The original description was published in 1794, based on a not-specified number of specimens all collected in Italy.Today these specimens are represented in the Fabricius collection by a single wing and a small piece of thorax attached to a pin (Fig. 2). The second description was presented in 1805 and based on two well-preserved specimens that are true syrphids and for which Thompson proposed the name Copestylum neotropicum (Thompson 1976) .</p><p>The single wing that remains from the specimens used for the original description has the typical venation of the genus Brachystoma and is therefore considered to belong to B. vesiculosum . Consequently this specimen is herewith designated as lectotype of Syrphus vesiculosus Fabricius (valid name Brachystoma vesiculosum) and labelled accordingly to fix and stabilize the current concept of the name (Fig. 2).</p><p>DIAGNOSIS. — Species blackish to brownish in ground color. Frons, face and thorax blackish with sparse grey pruinosity more or less visible depending on the orientation of the specimen. Coxae brownish to yellowish, femora yellow to brownish dorsally, tibiae and tarsi entirely blackish. Eyes dichoptic, antennae with a long stylus. Female postabdomen considerably modified, with tergite 7 enlarged, globose, developed laterally, enclosing segments 8 to 10 and cercus.</p><p>DISTRIBUTION (Fig. 8). — Austria, Croatia, France (mainland), Germany, Italy (mainland), Macedonia, Poland, Romania, Slovakia, Switzerland.</p><p>DESCRIPTION</p><p>Male (Figs 1; 3A; 4)</p><p>Head. Occiput black with a row of rather strong black postocular setae. Ocellar triangle black with orange-brown ocelli and a pair of fine setae. Antennae blackish; scape and pedicel of same length with a few fine, short setae, postpedicel a little longer than pedicel, stylus four times the postpedicel length. Frons and face blackish, the former a little broader than the latter. Labrum blackish, three times shorter than head height; labium short, very thick, spatula-like; palpus yellowish, short, rather thick, directed downwards, with yellowish fine, short hairs. Eyes dichoptic, all ommatidia of equal size.</p><p>Thorax. Black with sparse grey pruinosity on mesopleuron. Antepronotum with a pair of short, fine black setae. Postpronotum blackish to brownish anteriorly, without seta. One strong, long notopleural and postalar, scutellum with one pair of strong, long subapical setae, additional pair of fine, short apicals and moderatly long basal not always present or visible. All other setae inconspicuous, whitish, including one row of dorsocentrals. Acrostichals absent.</p><p>Legs. Fore coxa mainly brownish to yellowish ventrally, mid coxa mainly yellowish to brownish dorsally, hind coxa yellowish, all coxae covered with whitish vestiture, visible depending on the orientation, with 2-4 strong, long black setae. All trochanters brownish to yellowish. All femora yellow to more or less brownish dorsally; fore femur ventrally covered with minute spines, with two distinct anterolateral and anteroventral setae in apical half, 4-5 distinct posteroventral setae; mid femur ventrally covered with minute spines except basally, with anterolateral, antero- and posteroventral rows of 6-7 strong, long setae; hind femur ventrally covered with minute spines, with two distinct anterolateral setae apically, antero- and posteroventral rows of less than 10 strong, more or less long setae. All tibiae dark brown to black, with a regular ventral row of minute spines, one distinct dorsal seta at base; hind tibia somewhat thickened apically, ventrally covered with minute ventral whitish vestiture apically, distinct apical comb. All tarsi black without distinct setae.</p><p>Wings. Size 6-6.5 mm.

Phallus long, thin, bent anteriorly forming a characteristic loop.</p><p>Female (Figs 3B; 5)</p><p>Similar to male except for the following characters: postabdomen modified with tergite 7 enlarged, globose, developed laterally, enclosing segments 8 and 10 and cerci, but remaining open ventrally; sternite 7 lengthened posteriorly; tergite 8 well developed, well sclerotized anteriorly, with many dorsal minute spines; sternite 8 lengthened posteriorly, with distinct setae on the dorsal margin and a few shorter setae apically; tergite 10 with about 10 characteristic acanthophorites posterodorsally on each side; sternite 10 rather membranous with a few fine setae; cercus not horizontal but somewhat upright and bent anteriorly, well sclerotized apically.</p><p>DNA BARCODE</p><p>A 658 base-pair fragment of the COI gene was amplified and sequenced from two specimens (EMPB1, male, and EMPB4, female) Both sequences match 100% but the divergence rate with B. obscuripes is about 3%.</p></div>	https://treatment.plazi.org/id/03ABAC7BFFCD9429FF50FC45FE0533C1	Public Domain	No known copyright restrictions apply.

Loew (1856: 10) clearly specifies that his new species of Brachystoma was collected in Corsica by Mr Mann: “Sonst fiel mir unter Herrn Mann’s Corsikanischen Diptern eine neue Art der Gattung Brachystoma auf…”; in addition the label “ Corsica / Mann” was attached to the two specimens (Fig. 6). Therefore the type locality is more likely Corsica and not Sardinia as indicated in the original description (1856: 37).</p><p>The original description is based on male and female specimens but the number of specimens is not specified; the two specimens found in Loew collection correspond to the original description and here considered conspecific. Consequently the male is herewith designated as lectotype of Brachystoma obscuripes Loew and labelled accordingly to fix and stabilize the current concept of the name (Fig. 6). The second specimen, a female, becomes a paralectotype of the species.</p><p>DISTRIBUTION (Fig. 8). — France (Corsica); Italy (Sardinia).</p><p>DESCRIPTION</p><p>Similar to B. vesiculosum except for the following characters: smaller species (length of wing = 5-5.5 mm). Postocular setae somewhat stronger. Fore and mid coxae black-brown to yellowish posteroventrally, hind coxa brownish but more widely yellowish ventrally and posteriorly. All femora black with similar pattern of distinctly stronger setae. Male hypopygium distinctly smaller, cercus without pre-apical bulge, posterodorsal part of epandrium shorter, ventral epandrial setae not so strong, phallus not upright but more horizontal to the epandrium.</p><p>DNA BARCODE</p><p>A 658 base-pair fragment of the COI gene was amplified and sequenced from two specimens (EMPB15, male and EMPB12, female). Both sequences match 100% but the divergence rate with B. vesiculosum is about 3%.</p></div>	https://treatment.plazi.org/id/03ABAC7BFFCE9427FC21FA03FB5D3104	Public Domain	No known copyright restrictions apply.
