Diagnosis. Anepisternal setae black, moderately thicker on the superior region; three black notopleural macrosetae; no anatergal setae; 6 black apical scutellar setae; epandrium with a projection on ventral margin (Fig. 20); female tergite 9 + 10 membranous medially.

Redescription. Male. Lectotype (by present designation). Head. Scape and pedicel black with apical margin brown, postpedicel black; ocellar setae thin, except for 4 thicker ones; vertex and frons black with sparse golden tomentum; face black, golden tomentose; mystax with black macrosetae and some yellow setae; palpus with yellow to brown setae; proboscis black with yellow ventral setae; labial setae yellowish; occiput black with sparse golden and grey tomentum; occipital setae black and yellow; black postocular macrosetae arranged in long row, starting from lateral half of head until region above eyes.

Thorax. Antepronotum and postpronotum golden tomentose; mesonotum dark brown, with presutural and prescutellar golden spot and golden lateral margins with yellow to brown tomentum; mesopleuron black, grey and golden tomentose. Chaetotaxy: black anepisternal, moderately thick on superior region of anepisternum; 3 black notopleural macrosetae; 3 black supra-alar setae; 2 black postalar setae; black pre and postsutural dorsocentral setae; no anatergal setae; 6 black apical scutellar setae; black discal scutellar setae; black katatergal setae and seta on meron+metanepisternal blackish.

Wing (Figs. 22, 23). Light Brown, without costal dilation; crossvein r-m slightly beyond middle of discal cell; microtrichia on posterior wing margin arranged in single plane; halter yellow.

Legs. Black, except ventral region of tarsomeres brown (Fig. 19). Chaetotaxy: fore femur with only black and yellow ventral setae; mid femur with three black setae anteriorly, 4 black setae anteroventrally, one row of black setae from base to apex posteroventrally and 3 yellow setae basally, and 1 black, apical macrosetae posterodorsally; hind femur with 4 black macrosetae anteriorly, one row of black macrosetae from base to apex antero and posteroventrally, 1 black preapical macroseta anterodorsally and another posterodorsally, 1 black apical macrosetae posterodorsally; fore tibia with 3 black macrosetae posteriorly; mid tibia with one row of black setae posteriorly; hind tibia with 7 black setae anterodorsally and 6–8 posterodorsally; tarsomeres with black setae. Abdomen. Tergites 2–4 brown with yellowish apex; basal 1/4 of tergite 5 brown and apical 3/4 with grey tomentum; tergites 6–8 with shining silvery tomentum (Figs. 20, 22); lateral margin of tergites 2–5, golden tomentose; distal margin of sternite 8 without projections; sternites grey tomentose.

Terminalia (Figs. 19, 20, 22). Black. Oblique to body axis. Epandrium divided proximally and halves approximated medially; epandrium with ventral projection (Figs. 19, 20).

Length. Body 14.7 mm; wing 10.8 mm.

Lectotype condition. Left hind tarsomeres 2–5 missing; there are remnants of glue between the mid and hind trochanters and the pin.

Male paralectotypes body length: 14.4– 16 mm; wing 10.5– 11 mm.

Paralectotypes. Female: Similar to male, except for body length (14.6– 17 mm, wing 10.3–10.7 mm), brown tarsomeres, tergites 2–7 brown and apex and lateral margins, golden to brown tomentose; tergite 8 dark brown, long and slender (Fig. 24). Tergite 9 + 10 membranous medially.

Distribution. Venezuela (Fig. 75).

Comments. Diplosynapsis cellata has the typical wing (Fig. 23) of the genus, and its dubious placement in Diplosynapsis by Papavero (2009) does not proceed. The lectotype and paralectotype were designated in this study (Figs. 21, 25). This specimen was labelled as the lectotype accordingly, to fix and stabilize the current concept of the name.

Type material examined. Lectotype. (by pres. desig.) Lindig 1864, VENEZUELA / cellatus Alte Sammlung (♂ NMW).

Paralectotype: same data as holotype (3♂, 3♀ NMW).
