description: Opeatocerata agudeloi sp. nov.
(Figs 8–16)
Diagnosis. Yellow species; posterior cercus with acuminate apex in lateral view (Fig. 11), without dorsal projections (Fig. 12); phallus subcylindrical, wider at apex, with a narrow dorsal subbasal appendix and ventral subapical appendix (Fig. 15).
Description. Male (Fig. 8). Head: Face parallel-sided, dark brown, without visible pruinescence in ventral view, about 4X longer than lower width. Ocellar tubercle protuberant, dark brown, without pruinescence; ocelli yellow. Antenna yellow with black bristles; postpedicel about 2X longer than pedicel; stylus about 2X longer than postpedicel. Proboscis yellow, shorter than head height. Thorax yellow, shiny (Fig. 8). Legs yellow except hind tibia with apical black ring and tarsomeres 4–5 black; hind tibia and tarsus with anterodorsal and posterodorsal row of longer bristles. Wing (Fig. 9) hyaline; pterostigma brown, conspicuous, about 2.6X longer than wide. Halter yellow. Abdomen yellow, shiny (Figs 8, 10); tergite 8 divided in two subrectangular plates; sternite 8 divided in two trapezoidal plates. Terminalia: Anterior cercus with proclinate dorsal projection in lateral view (Figs 10, 11); concave in dorsal view (Fig. 12); descendant plate with lower margin slightly bilobed and narrower than superior margin in posterior view (Fig. 13). Posterior cercus with acuminate apex in lateral view (Fig. 11), without dorsal projections (Fig. 12). Hypoproct subtriangular in lateral view (Fig. 11) and comma-shaped in posterior view. Epandrial ventral lobe with bilobed apex (Fig. 11), with spiniform bristles mesially on dorsal lobe, and longer bristles at apex of ventral lobe (Fig. 11). Hypandrium longer than wide, with median sinus apically (Fig. 16), without long bristles. Phallus subcylindrical, wider at apex, longer than hypandrium, with long and narrow dorsal appendix and short ventral appendix (Fig. 15). Subepandrial sclerite wider than long, U-shaped (Fig. 14). Bacilliform sclerite folded and longer than subepandrial sclerite (Fig. 14). Specimen length: 3.6 mm; wing length: 3.5 mm. Female. Unknown.
Geographical distribution. Colombia (Leticia) (Fig. 211).
Type material. HOLOTYPE ♂, labelled: Colombia, AMZ [Amazonas], Letícia, Reserva Tanimboca, Km 11 via Tarapacá, 4º13’S; 69º56’W, 24–29.iv.2011, Arm[adilha] Luz. Antonio Agudelo leg. (CEUA).
Holotype condition. Left wing on microslide; abdomen in microtube with glycerin.
Etymology. The specific epithet is a tribute to Antonio Agudelo, the specimen collector.
Remarks. Opeatocerata agudeloi sp. nov. is similar to O. mourai sp. nov. by the posterior cercus with acuminate apex in lateral view (Figs 11, 132), epandrial lobe bilobed at apex (Figs 11, 132) and phallus with subbasal dorsal appendix (Figs 15, 136). Differs from the latter by the anterior cercus with proclinate dorsal projection in lateral view (Fig. 11) and phallus with ventral subapical appendix (Fig. 15). Opeatocerata mourai sp. nov. has the anterior cercus with dorsal pro and reclinate projections in lateral view (Fig. 32) and phallus without ventral appendix (Fig. 136).
