description: Opeatocerata tanimboca sp. nov.
(Figs 185–194)
Diagnosis. Tergites 3–6 with paramedian suboval black spots (Figs 185, 188); epandrium ventral lobe slightly bilobate apex (Fig. 189); phallus subcylindrical with dorsal subapical spine (Fig. 193).
Description. Male (Fig. 185). Head: Face parallel-sided, dark brown with gray pruinescence visible in ventral view, about 4X longer than lower width. Ocellar tubercle protuberant, dark brown with gray pruinescence; ocelli brown. Scape, pedicel and postpedicel brown with black bristles; postpedicel about 1.5X longer than pedicel; stylus about 3X longer than postpedicel. Proboscis dark yellow, shorter than head height. Thorax yellow, shiny (Fig. 185). Legs yellow, except for all tarsomeres 4–5 black; mid, hind tibia and hind tarsomere 1 with anterodorsal, posterodorsal, anteroventral and posteroventral rows of longer bristles. Wing (Fig. 186) hyaline, pterostigma, brown, conspicuous, about 2.7X longer than wide. Halter light yellow. Abdomen dark yellow, shiny; tergites 3–6 with paramedian suboval black spots (Figs 185, 188); tergite 8 divided in two subrectangular plates; sternite 8 divided in two subtriangular plates. Terminalia: Anterior cercus with proclinate dorsal projection in lateral view (Figs 187, 1189), posterior margin truncate and with a median sinus in dorsal view (Fig. 211); descendant plate subtrapezoidal in posterior view (Fig. 191). Posterior cercus with a rounded apex in lateral view (Figs 187, 188) and with a dorsal submedian subtriangular projection in dorsal view (Fig. 191). Hypoproct subrounded in lateral view (Fig. 189) and comma-shaped in posterior view (Fig. 191). Epandrium ventral lobe with slightly bilobate apex (Fig. 189); without spiniform bristles, longer bristles apically on ventral lobe (Fig. 189). Hypandrium wider than long, with concave apex (Fig. 194), without long bristles. Phallus subcylindrical, longer than hypandrium, with dorsal subapical spine (Fig. 193). Subepandrial sclerite wider than long, U-shaped (Fig. 192). Bacilliform sclerite with folds and longer than subepandrial sclerite (Fig. 192). Specimen length: 3.2 mm; wing length: 3.3 mm. Female. Unknown.
Geographical distribution. Colombia (Leticia) and Brazil (Amazonas) (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). Paratype: Brazil, Amazonas. Tabatinga, 13–17.i.1992, Arm[adilha] Malaise, J. Vidal & Lílian (1 ♂, INPA).
Holotype condition. Good; left wing mounted on microslide; abdomen in microtube with glycerin.
Etymology. The specific epithet is a noun in apposition and refers to Reserva Tanimboca, Leticia, Colombia, the locality where the holotype was collected.
Remarks. Opeatocerata tanimboca sp. nov. differs from other species in the tergites with paramedian suboval spots (Fig. 188) (in other species it is subtriangular or subrectangular), anterior cercus with descendant plate subtrapezoidal (Fig. 191) (in other species this plate is either subtriangular, subrectangular, with lateroventral expansions or hourglass-shaped) and phallus with dorsal subapical spine (Fig. 193) (in other species there is no dorsal subapical spine on the phallus).
