Face occupying around 2 / 5 of head width in frontal view; shiny black; white setulose laterally, black setulose sublaterally, bare at median part as wide as ~ 1 / 4 of width of face. Gena very narrow; black; white setulose. Oral margin laterally not produced. Frons black; medially bare, laterally black setulose. Vertex black; black setulose. Occiput black; dorsal 1 / 2 black setulose, ventral 1 / 2 white setulose. Eye bare. Antenna black, except pedicel and basal 1 / 6 of postpedicel brown; antennal ratio ~ 7: 1: 7.5.</p><p>Thorax. Scutum shiny black, with bronze sheen on lateral 1 / 3 and faint dark blue sheen on median 1 / 3; black setulose, except for narrow fascia of golden yellow setulae along anterior margin. Postpronotum of same colour as scutum; black and dark yellow setulose. Postalar callus dark brown; black setulose. Scutellum trapezoid, with two calcars as long as ~ 1 / 3 of scutellar length; of same colour as scutum except calcars largely pale brown; black setulose anteriorly and medially, yellow setulose laterally and posteriorly. Pleura shiny blackish brown, except anepimeron and katepimeron pale brown. Anepisternum with shallow sulcus; dark yellow setulose anteriorly, black setulose posteriorly, widely bare medially and ventrally. Anepimeron black setulose anteriorly, dark yellow setulose posteriorly. Katepisternum with patch of pale yellow setulae dorsally and small patch of yellow setulae ventrally. Katatergite long microtrichose, anatergite short microtrichose. Calypter greyish yellow and halter pale yellow.</p><p>Wing: hyaline; microtrichose, except bare on basal 1 / 3 of cell r 1, a small basal patch of r 2 + 3, most of cell br (only microtrichose along vena spuria), most of cell bm except for narrow median strip of microtrichiae, large part of cell dm (Fig. 24), anterobasal 1 / 2 of cell cup, and basomedian 3 / 4 of alula.</p><p>Legs: femora black, only apex brown; black setulose. Tibiae brown at both ends, blackish in between; largely black setulose, with some pale setulae ventrally. Tarsi orange-brown; black setulose dorsally, golden yellow setulose ventrally. Coxae and trochanters blackish; fore and mid coxae black setulose anteriorly, pale setulose posteriorly; hind coxa silvery white setulose.</p><p>Abdomen. Tergites black to blackish brown, slightly paler along lateral margins. Tergite 1 black setulose. Tergite 2 shiny, except for oval median dull macula and pair of smaller, oblique lateral maculae; black setulose, except yellow setulose in anterolateral corners, and white setulose along posterior margin. Tergite 3 dull, except for narrow shiny strips along lateral and posterior margins; black setulose, except narrowly white setulose along posterior margin. Tergite 4 shiny; black setulose, except white setulose in anterolateral corners and on pair of larger posterior patches. Sternites blackish; sternites 1–3 white, setulose, sternite 4 black setulose. Genitalia as in Fig. 138.</p><p>Female. Unknown.</p><p>Diagnosis.</p><p>Body length: male 9.5–10 mm (n = 2). Superficially, this species looks most similar to S. chloraspis Reemer, sp. nov., S. pallitarsis Reemer &amp; Mengual, sp. nov., and S. varicaudata Reemer &amp; Mengual, sp. nov., which are of similar size and colouration. These species also share the following combination of characters: face black, tibiae entirely brown, tergite 3 broadly dull with narrow shiny margins (Fig. 58). Serichlamys boti Reemer, sp. nov. differs from the three other species, as well as from all other known species of Serichlamys, in the partly bare wing cell dm (Fig. 24). It also differs from the three species mentioned above in the presence of only two basoventral setae on the surstylus (Fig. 138) (instead of 4 or 5 in the other three species, Figs 139–141). Serichlamys boti Reemer, sp. nov. is similar to S. pallitarsis Reemer &amp; Mengual, sp. nov. in the pattern of dull maculae on tergite 2: dull maculae narrower than shiny areas separating them (wider than shiny areas in S. chloraspis Reemer, sp. nov. and S. varicaudata Reemer &amp; Mengual, sp. nov.) (compare Figs 31, 33). Serichlamys boti Reemer, sp. nov. and pallitarsis Reemer &amp; Mengual, sp. nov. also share orange tarsi (dark in S. chloraspis Reemer, sp. nov. and S. varicaudata Reemer &amp; Mengual, sp. nov.). However, the partly bare wing cell dm (entirely microtrichose in S. pallitarsis) and the two basoventral setae on the surstylus (4 or 5 in S. pallitarsis Reemer &amp; Mengual, sp. nov.) clearly separate this species.</p><p>The holotype and the paratype differ in the colour of the setulae on the scutum: black except for narrow fascia of golden yellow setulae along anterior margin in the holotype, entirely golden yellow in the paratype.</p><p>Etymology.</p><p>The name of this species is a patronym in honour of Sander Bot, who collected the holotype and one of the paratypes.</p><p>Distribution.</p><p>This species is known from two localities on the western slope of the Andes: one in Colombia (elevation 1481 m), and one locality in Ecuador (elevation 1450 m).</p></div>	https://treatment.plazi.org/id/9280DAEBDBAA5ECAB5F8CCCEDBAC3678	Public Domain	No known copyright restrictions apply.

Superficially, this species looks most similar to S. boti Reemer, sp. nov., S. pallitarsis Reemer &amp; Mengual, sp. nov. and S. varicaudata Reemer &amp; Mengual, sp. nov., which are of similar size and colouration. These species also share the following combination of characters: face black, tibiae entirely brown, tergite 3 broadly dull with narrow shiny margins (Fig. 64). However, this is the only known species of Serichlamys with a strong metallic green shine on scutum and scutellum (Figs 31, 64). A weak metallic, sometimes green, shine also occurs in other species, but not as strong. In addition, there is a pair of large, smooth, metallic green maculae on tergite 2 (Fig. 31) (these maculae are not green in the three species mentioned above).</p><p>Etymology.</p><p>The specific epithet is composed of the Greek words chloros (green) and aspis (shield). This name refers to the metallic green scutum and scutellum of this species.</p><p>Molecular data.</p><p>The holotype male was successfully sequenced and its DNA barcode clusters together (BS = 100) with the COI sequence of one of the paratypes (MZH S 264), which had previously been identified as ‘ Microdon CR 99-10 ’ in GenBank, and a public sequence of another Serichlamys specimen from Costa Rica, previously identified as Microdon MRC- 20. Both codes or name-holders are known to be used by F. C. Thompson and likely refer to the same species, S. chloraspis Reemer, sp. nov.</p><p>Distribution.</p><p>This species is only known from Costa Rica, where it was found in the centre and southeast of the country at elevations between 50 and 1200 meters.</p></div>	https://treatment.plazi.org/id/3C87FDB12F7B5B25BAC7DA126686EA09	Public Domain	No known copyright restrictions apply.

These species also share the following combination of characters: face black, tibiae entirely brown, tergite 3 broadly dull with narrow shiny margins. From S. chloraspis Reemer, sp. nov. and S. varicaudata Reemer &amp; Mengual, sp. nov. this species differs by the entirely orange tarsi (dark in S. chloraspis Reemer, sp. nov. and S. varicaudata Reemer &amp; Mengual, sp. nov.). From S. boti Reemer, sp. nov. it differs by the entirely microtrichose wing cell dm (partly bare in S. boti Reemer, sp. nov.), as well as by the presence of 4 or 5 basoventral setae on the surstylus (2 in S. boti Reemer, sp. nov.).

Tergites 4 and 5 are entirely yellowish brown.</p><p>Diagnosis.</p><p>Body length: male 7.5–8.5 mm (n = 10), female 8.5 mm (n = 1). Together with S. simpliciphallus Reemer, sp. nov. and S. spathulata Reemer, sp. nov., this species belongs to a group of three species of which most (not all!) specimens have dorsoventrally flattened, spoon-shaped calcars on the scutellum (Figs 51–57). From S. spathulata Reemer, sp. nov. it differs by the presence of separate patches of microtrichia on tergite 2 (Fig. 48), the brown postpedicel, and the structure of the male genitalia (Fig. 148). From S. simpliciphallus Reemer, sp. nov. this species can only be reliably distinguished by the structure of the male genitalia, most notably the shape of the phallus: S-shaped in S. serpentiphallus Reemer, sp. nov., straight in S. simpliciphallus Reemer, sp. nov. Other characters, such as colouration of integument and setulosity, as well as distribution of microtrichia on the tergites, were found to be too variable among the studied specimens. Females are undistinguishable from S. simpliciphallus Reemer, sp. nov. at present.</p><p>Etymology.</p><p>The name serpentiphallus is a noun composed of the Latin words serpens (snake) and phallus (phallus). It refers to the s-shaped phallus of the male of this species.</p><p>Molecular data.</p><p>The female from São Luis do Paraitinga (CNC 1059095) was successfully sequenced. The identification of this specimen was based on the fact that it was collected at the same locality and date as CNC 1059094, a male which was identified based on its genitalia. The DNA barcode is placed with high support (BS = 99.6) together with a cluster that includes the sequences of S. spathulata Reemer, sp. nov. and Serichlamys sp. (CNC 1059093; GenBank accession no. PQ 629019), although they differ considerably (similarity = 87.459 –87.541 %)</p><p>Distribution.</p><p>This species is known from the Brazilian States of São Paulo and Rio de Janeiro.</p></div>	https://treatment.plazi.org/id/3F8873C640975259A6626D7B6130E909	Public Domain	No known copyright restrictions apply.

Coxae and trochanters brown; yellow to white setulose.</p><p>Abdomen. Tergites dark brown, except lateral margins and posterior margins of tergites 3 and 4 paler brown. Tergite 1 yellowish setulose. Tergite 2 with three large patches of grey microtrichiae, with narrow shiny parts in between; medially white setulose, laterally yellow setulose.

Tergite 4 semi-shiny; golden yellow setulose laterally and posteriorly, black setulose anteriorly and medially. Sternites yellowish brown; yellowish white setulose. Genitalia as in Fig. 149.</p><p>Female. One female (see Additional specimens) probably belonging to this species was collected at the same site and date as one of the male paratypes. Apart from usual sexual dimorphism, no important differences were noted.</p><p>Diagnosis.</p><p>Body length: male 8–8.5 mm (n = 12), female 9 mm (n = 1). Together with S. serpentiphallus Reemer, sp. nov. and S. spathulata Reemer, sp. nov., this species belongs to a group of three species of which most (not all!) specimens have dorsoventrally flattened, spoon-shaped calcars on the scutellum (Figs 51–57). From S. spathulata Reemer, sp. nov. it differs by presence of separate patches of microtrichia on tergite 2 (Fig. 48), the brown postpedicel, and the structure of the male genitalia (Fig. 149). From S. simpliciphallus Reemer, sp. nov. this species can only be reliably distinguished by the structure of the male genitalia, most notably the shape of the phallus: S-shaped in S. serpentiphallus Reemer, sp. nov., straight in S. simpliciphallus Reemer, sp. nov. Other characters, such as colouration of integument and setulosity, as well as distribution of microtrichia on the tergites, were found to be too variable among the studied specimens. Females are undistinguishable from S. serpentiphallus Reemer, sp. nov. at present.</p><p>Molecular data.</p><p>An unidentified female specimen from Estação Biológica de Boracéia (Salesópolis, Sao Paulo, Brazil; CNC 1059093; GenBank PQ 629019) possibly belongs to S. simpliciphallus . Its DNA barcode clusters with the sequences of S. spathulata Reemer, sp. nov. (BS = 100).</p><p>Etymology.</p><p>The name simpliciphallus is a noun composed of the Latin words simplex (simplicity) and phallus (phallus). It refers to the ‘ simple’ shaped phallus of the male of this species, in contrast with the otherwise morphologically very similar S. serpentiphallus .</p><p>Distribution.</p><p>This species is only known from the Brazilian State of São Paulo.</p></div>	https://treatment.plazi.org/id/4CF2093CEBB359629928F7A395FF357F	Public Domain	No known copyright restrictions apply.

As male, except for following differences. Body length 10 mm (n = 1). Antenna: scape and pedicel brow, postpedicel blackish. Legs entirely yellowish brown. Tergite 5 dark brown; yellowish setulose laterally and posteriorly, black setulose anteriorly and medially.</p><p>Diagnosis.</p><p>Body length: male 7–8 mm (n = 10), female 10 mm (n = 1). Together with S. serpentiphallus Reemer, sp. nov. and S. simpliciphallus Reemer, sp. nov., this species belongs to a group of three species of which most (not all!) specimens have dorsoventrally flattened, spoon-shaped calcars on the scutellum (Figs 51–57). From both species, as well as from S. mus (Curran), it differs by the wide fascia of grey microtrichia on tergite 2, with at most a pair of smaller round bare parts laterally (Figs 46, 47). It also differs from the three aforementioned species by the black postpedicel (at most basal 1 / 4 paler). Male genitalia as in Fig. 147.</p><p>Notes.</p><p>The distribution of microtrichia on the wing is very variable. For instance, in the holotype cell cup is entirely microtrichose, but in some paratypes it is partly bare. In some specimens the alula is almost entirely microtrichose, while in other ones there is a large bare patch basomedially, and intermediates occur.</p><p>Etymology.</p><p>The name spathulata is an adjective derived from spatha, the Latin word for spoon. It refers to the spoon-shaped scutellar calcars.</p><p>Molecular data.</p><p>Five DNA barcodes were obtained for this species, which cluster together in our NJ tree (BS = 100). As sister taxon we recovered Serichlamys sp.

Face occupying ~ 2 / 5 of head width in frontal view; shiny black; white setulose, except black setulose on dorsal 1 / 4. Gena very narrow; black; white setulose. Oral margin laterally not produced. Frons black; medially bare, laterally black setulose except white setulose along eye margin. Vertex black; black setulose. Occiput black; dorsal 1 / 2 golden yellow setulose, ventral 1 / 2 white setulose. Eye bare. Antenna: scape black, pedicel and postpedicel dark brown; antennal ratio ~ 4: 1: 5.</p><p>Thorax. Scutum shiny black with bronze sheen; golden yellow setulose. Postpronotum and postalar callus shiny brown; golden yellow setulose. Scutellum trapezoid, of same colour as scutum, with two apical calcars as long as ~ 2 / 5 of scutellar length. Pleura greyish brown, except meron and ventral parts of katepisternum blackish. Anepisternum with shallow sulcus; golden yellow setulose anterodorsally and posterodorsally, widely bare medially and ventrally. Anepimeron golden yellow setulose. Katepisternum with patch of white setulae dorsally and a few white setulae ventrally. Katatergite long microtrichose, anatergite short microtrichose. Calypter and halter pale yellow.</p><p>Wing: hyaline; microtrichose, except bare on basal 1 / 4 of cell r 1, most of cell br (only microtrichose along vena spuria), posterobasal 1 / 2 of cell bm, anterobasal 1 / 3 of cell cup, and basomedian 3 / 5 of alula.</p><p>Legs: femora black; yellow to white setulose. Tibiae black, apices narrowly brown; white setulose. Tarsi black with apical tarsomere yellowish brown; black setulose dorsally, yellow setulose ventrally. Coxae and trochanters blackish; yellow and white setulose.</p><p>Abdomen. Tergites blackish, with lateral and posterior margins brown. Tergite 1 yellowish white setulose. Tergite 2 shiny with three large dull maculae; yellowish white setulose. Tergite 3 dull on most of surface, with lateral and posterior margins shiny; yellowish white setulose on shiny parts, black setulose on dull parts. Tergite 4 semi-shiny; reddish yellow setulose laterally and posteriorly, black setulose anteriorly and medially, white setulose in anterolateral corners. Sternites blackish; yellow setulose. Genitalia as in Fig. 141.</p><p>Female. As male, except for following differences. Face, frons, and vertex black setulose except for pair of small patches of white setulae along eye margin. Scutum, scutellum, and pleura black setulose. Tergite 5 yellow to yellowish brown; yellow setulose.</p><p>Diagnosis.</p><p>Body length: male 9–10 mm (n = 10), female 11–12 mm (n = 2). Superficially, this species looks most similar to S. boti Reemer, sp. nov., S. chloraspis Reemer, sp. nov., and S. pallitarsis Reemer &amp; Mengual, sp. nov., which are of similar size and colouration. These four species all have a black face, entirely dark tibiae, a uniformly coloured postpedicel, and a large rectangular dull area on tergite 3. The combination of the following characters distinguishes S. varicaudata Reemer &amp; Mengual, sp. nov. from the other three species: wing cell dm entirely microtrichose (partly bare in S. boti Reemer, sp. nov.), scutum and scutellum without strong metallic green shine (green metallic in S. chloraspis Reemer, sp. nov.), tergite 2 with lateral dull parts large (Fig. 33) (small in S. boti Reemer, sp. nov. and S. pallitarsis Reemer &amp; Mengual, sp. nov.; Figs 30, 32), hind metatarsus dorsally black (orange in S. boti Reemer, sp. nov. and S. pallitarsis Reemer &amp; Mengual, sp. nov.). Male genitalia as in Fig. 141.</p><p>Notes.</p><p>In the studied male specimens, the degree to which tergite 4 is covered with red setulae varies from only the apical 1 / 3 to the entire tergite (Figs 123–125). The colour of the setulae on the vertex also varies from entirely golden yellow to entirely black.</p><p>Etymology.</p><p>The specific epithet is composed of the Latin words varius (different) and cauda (tail). The name refers to the variability of the colouration of both integument and setulosity of tergite 4.</p><p>Molecular data.</p><p>Several DNA barcodes were successfully obtained from multiple specimens from Ecuador and they were recovered in a well-supported cluster (BS = 98.8) in the NJ tree. The intraspecific similarity ranges from 99.111 to 100 %.</p><p>Distribution.</p><p>This species is only known from Ecuador, where it was found on eastern and western slopes of the Andes at elevations between 1800 and 2200 meters.</p></div>	https://treatment.plazi.org/id/C402A79A34DD5EE08B5C26525CA70278	Public Domain	No known copyright restrictions apply.

Face occupying slightly &lt;1 / 3 of head width in frontal view; shiny black with faint green hue; white setulose. Gena very narrow; black; white setulose. Oral margin laterally not produced. Frons black; medially bare, laterally with mixed white and black setulae. Vertex black; black setulose except yellowish setulose along anterior and posterior margins. Occiput black; dorsal 1 / 3 pale yellow setulose, otherwise white setulose. Eye bare. Antennal fossa slightly higher than wide. Antenna blackish brown; antennal ratio ~ 4: 1: 4.5.</p><p>Thorax. Scutum shiny black, with green sheen on median 1 / 3 and bronze sheen on lateral 1 / 3; black golden yellow setulose on anterior 1 / 4 and narrowly along lateral and posterior margins, otherwise black setulose. Postpronotum and postalar callus yellowish brown; yellow setulose. Scutellum trapezoid, with two calcars as long as ~ 1 / 4 of scutellar length; shiny dark brown with faint greenish sheen, except calcars yellow; yellow setulose. Pleura shiny dark to yellowish brown. Anepisternum with shallow sulcus; yellow setulose anterodorsally and posterodorsally, widely bare medially and ventrally. Anepimeron yellow setulose with a few black setulae dorsally. Katepisternum with patch of white setulae dorsally and small patch of white setulae ventrally. Katatergite long microtrichose, anatergite short microtrichose. Calypter pale yellow, halter white.</p><p>Wing: hyaline; microtrichose, except bare on basal cell bc, posterobasal 1 / 3 of cell c, basal 3 / 5 of cell r 1, basal 1 / 8 of cell r 2 + 3, most of cell br (only microtrichose along vena spuria), slightly more than posterior 1 / 2 of cell bm, anterior 1 / 2 of cell cup, and basomedian 2 / 3 of alula.</p><p>Legs: femora blackish brown with yellow apices; yellow setulose. Tibiae pale yellow at basal 2 / 3, pale brown at apical 1 / 3, and blackish brown around cicatrix; yellow setulose except black setulose on inner side at apical 1 / 3. Tarsi pale brown; black setulose dorsally, yellow setulose laterally and ventrally. Coxae and trochanters brown; pale yellow to white setulose.</p><p>Abdomen. Tergites blackish brown, mostly shiny except for large part of tergite 3. Tergite 1 white setulose. Tergite 2 shiny except for small median dull macula, with distinct metallic sheen at lateral 1 / 4; whitish setulose, except for some black setulae along lateral margin. Tergite 3 dull black, except for narrow fascia with bronze sheen along posterior and lateral margins; dull part short black setulose except for pale setulae posteromedially, shiny parts longer yellowish white setulose. Tergite 4 entirely shiny but not metallic; mostly short black setulose, but longer pale yellow to whitish setulose along lateral margins and on pair of large posteromedian patches. Sternites blackish brown; all sternites white setulose. Genitalia as in Figs 150–153: phallus with large, subapical flag-like projection.</p><p>Female (based on paratype) As male, except for usual sexual dimorphism and following differences. Scutum largely black setulose, except for yellowish setulae along anterior margin. Tergites somewhat paler brown than in male.</p><p>Diagnosis.</p><p>Body length: male 6.0–7.0 mm (n = 19), female 8.5–9 mm (n = 3). The combination of a black face with a contrasting colour pattern on the tibiae (Fig. 7) sets this species apart from all other species in the genus. Besides, the male genitalia are very distinct in the fact that the phallus carries a ‘ flag-like’ apicodorsal projection (Figs 150–153).</p><p>Notes.</p><p>This is the only known species of Serichlamys in which the male has a flag-like appendix on the phallus. Some slight variation occurs in the shape of this appendix (Figs 150–153), but this is considered to be intraspecific. Little variation among the specimens (mostly subtle differences in colouration) was noted in external characters, except that the colour of setulosity on the scutum may vary between entirely golden yellow to mostly black. No habitat information is indicated on the labels of the specimens, but the localities suggest that they were found at the margins of tropical rain forest.</p><p>Etymology.</p><p>The specific epithet is a noun in apposition composed of the Latin words vexillum (flag) and phallus (penis). It refers to the characteristic dorsal projection on the phallus in males of this species.</p><p>Molecular data.</p><p>A specimen from Ecuador and another from Peru were sequenced. Both DNA barcodes cluster together with high-support (BS = 100) and they have a similarity of 97.833 %.</p><p>Distribution.</p><p>This species is known from Ecuador (n = 13), Peru (n = 1) and Panama (n = 1). In the first two countries, it has been found at elevations between 300 and 1100 meter, at slopes of the Andes and in lowland rainforest. In Panama it was found in rainforest at 800 meters of altitude. Based on these records, it can be expected that this species also occurs in Colombia.</p></div>	https://treatment.plazi.org/id/C4D2B1C6D080536F8F690EB346C985E3	Public Domain	No known copyright restrictions apply.
