Leinendera achaeta   sp. n. Figs 2-7, 8-15


Apical scutellar macrosetae absent; epandrium elongate, apical 1/3 triangular in lateral view (Figs 8-11); gonocoxite with an indentation on apical third of the inner margin (Figs 9, 10); hypandrium with distal margin straight, basal margin rounded (Fig. 12).

Male. Holotype. Body: Slender (Fig. 2). Head: Antenna (Fig. 5) with yellow scape and pedicel, with brown and yellow setae; yellow postpedicel with brown apex, and 16 times the length of first element of the stylus; stylus brown; second element of stylus five times the length of the first element. Vertex (Fig. 3) golden tomentose; ocellar tubercle brown tomentose with two brown, short, proclinate, ocellar setae; face and frons golden tomentose (Fig. 3), face moderately narrow (Fig. 3), lower facial margin silvery tomentose; gena dark-brown; pale yellow mystacal macrosetae (Figs 3, 4); occiput golden-brown tomentose; yellow occipital setae; 4-6 light brown postocular macrosetae; brown palpus with brown setae; apical setae of palpus longer than others; light brown labrum, lacinia and postmentum, black labella and prementum; yellowish labial setae.

Thorax (Figs 2, 4). Antepronotum and postpronotum brown and golden tomentose; brown mesonotum; brown paramedian stripe, darker on anterior half; presutural and postsutural spots brown tomentose, area between spots grey tomentose; mesonotum grey tomentose laterally; brown scutellum with impressed rim, silvery tomentose; pleuron silvery tomentose with brown oblique stripe extending from base of wing to base of fore and mid coxae (Fig. 4). Chaetotaxy: Brown acrostichal setae; two brown notopleural macrosetae; one brown supra-alar macroseta and 1 brown supra-alar seta; one brown postalar macroseta; four brown, dorsocentral, presutural setae; four brown, dorsocentral, postsutural setae; apical scutellar macrosetae absent; one short, brown, discal scutellar seta; yellowish anatergal and katatergal setae; posterior meron + metanepisternum with yellow macroseta and pale yellow tuft of small setae on posterior margin.

Wing (Figs 6, 7). Hyaline basal 2/3, apical 1/3 extending to anal margin reaching anal cell with dense brown microtrichiae; dark brown veins; R2+3 slightly sinuous at the level of the R4 and R5 bifurcation; cell r4 narrower basally; without costal dilatation; R4 and R5 bifurcation beyond level of the discal cell apex; crossvein r-m before level of discal cell middle (Obs. the additional r-m on figure 6 is an anomaly); microtrichia on posterior margin arranged in two divergent planes; pale-yellow halter.

Legs (Figs 2, 4). Narrow, yellow; apex of all femora with dark brown ring. Chaetotaxy: Hind trochanter with 1 yellow macrosetae; fore femur with 4 yellow setae ventrally; mid femur with 1 yellow anterior macroseta, 2-3 yellow macrosetae anteroventrally, 2-3 yellow macrosetae posteroventrally and 1 yellow, posterior, preapical macroseta; hind femur with 2 yellow anterior macrosetae, 2-3 dorsal preapical macrosetae and 3 yellow macrosetae posteroventrally; fore tibia with 3 yellow long macrosetae laterally; mid tibia with 4 yellow long macrosetae anteroventrally, 1 yellow posterior macroseta and 2 yellow macrosetae posteroventrally; hind tibia with 3 yellow anterior setae, 2 yellow posterior setae, 1 yellow anteroventral seta and 3 yellow posteroventral setae; tarsomere with yellow setae and macrosetae; yellow empodium and pulvillus; claws with light brown basal half and black apical half.

Abdomen (Fig. 2). Brown. Dark brown tergites, except I–III light brown laterally; tergites III–VI with silvery tomentose spots laterally; tergites with yellow, lateral, marginal macrosetae. Light brown sternites, except dark brown V–VI.

Terminalia (Figs 8-15). Light brown. Epandrium elongate, apical 1/3 triangular in lateral view (Figs 8-11); hypandrium with distal margin straight, proximal margin rounded (Fig. 12); gonocoxite with an indentation on apical third of inner margin (Figs 9, 10); gonostyle tapered and with rounded apex (Fig. 13); apex of subepandrial sclerite rounded (Fig. 14); ejaculatory apodeme narrow in lateral view (Fig. 15), aedeagal sheath subtriangular in lateral view (Fig. 15).

Length: Body length 11.9 mm; wing length 10.9 mm.

Holotype condition: Right postpedicel and right hind tarsus lost. Detached wing mounted on microslides, terminalia placed in microvial with glycerin, both pinned with the specimen.

Variation (n = 2): Size. Body length 11.5-12.4 mm; wing length 10.1-10.5 mm. Face silvery tomentose; mid femur with 1-3 yellow anterior macrosetae; mid tibiae with 3 yellow long macrosetae anteroventrally.

Female: Unknown.


From the greek achaeta, a = absent and chaeta = bristles, referring to the absence of apical scutellar macrosetae.


All specimens of Leinendera achaeta   sp. n. were collected with Malaise traps placed in tobacco, Nicotiana tabacum   L., plantations. The vegetation surrounding the tobacco plantations was composed mainly by grasslands and shrubs of small to medium size. No information about the prey is known.


Differs from the other two species of Leinendera   by the absence of apical scutellar macrosetae and characters of the terminalia (Figs 2-15). When describing Leinendera   , Carrera (1945) mentioned that the genus was distinct from Glaphyropyga   by the presence of apical scutellar setae. However, that author described the taxon based on a single species and, with the inclusion of Leinendera achaeta   sp. n., this character can no longer be used in the diagnosis of the genus. Regardless, Leinendera achaeta   sp. n., Leinendera nigra   Vieira, 2012 and Leinendera rubra   Carrera, 1945 have a brown oblique stripe extending from the base of the wing to the base of the fore and mid coxae (Figs 16, 24), which could be used as a new diagnostic character for the genus, since it does not occur in any other closely related genus of Asilinae  .
