Neoplasta lobata sp. nov.

( Figs 9–15 )

Diagnosis. A brown species with yellow legs ( Fig. 9 ); cercus rounded at apex ( Fig. 12 ); hypoproct subrectangular ( Fig. 13 ); hypandrium with rounded lobes laterally and digitiform lobes ventrally ( Figs 12, 14, 15 ).

Description. Male ( Fig. 9 ). Head ( Fig. 9 ): Dark brown to black, all setae whitish yellow. Ocellar triangle with 1 pair of divergent proclinate setae; anterior ocellus larger. Eye iridescent black, ommatidia enlarged anteriorly. Frons with 2 frontal setulae; 1–2 pairs of vertical setae contiguous with uniseriate row of postocular setae. Face 5X longer than wide, converging ventrally, bearing fine reclinate setulae. Occiput bearing scattered fine hairs. Mouthparts yellow; proboscis slightly curved with yellow setae. Antenna brown, with scape and pedicel bearing distinct short, dorsal setulae; postpedicel short, lanceolate, 1.2X as long as wide, stylus about 0.1X as long as postpedicel. Thorax ( Fig. 9 ): Brown, elongate, slightly arched ventrally. Pronotum with anterior margin almost straight and scutum with yellow setae, very small and fine, except 1 notopleural, 1 postalar and 2 pairs of scutellar setae. Legs ( Fig. 9 ): Yellow. Fore coxa ~ 1.1X as long as distance between fore- and mid coxae, 3X as long as wide, with a few setae dorsally. Fore femur ~ 1.3X longer than fore coxa, with row of strong 8 anteroventral and 19 posteroventral denticles, with anteroventral row on apical third. Fore tibia as long as fore femur. Mid- and hind legs slender, with fine setae. Wing ( Fig. 10 ): Membrane faintly yellow, veins yellowish; vein R2+3 short, gently arched to C apically, joining C ~ 0.3X of distance between end of R1 and R4; R4+5 fork angle acute (~ 70°); cell bm+dm very long, ~2.0X as long as cell br. Halter brownish. Abdomen ( Fig. 9 ): Brown. Terminalia: Brown. Cercus narrower basally and rounded at apex, in lateral view ( Fig. 12 ); left and right cerci closely approximated anterodorsally, with scattered setae on outer face ( Fig. 11 ). Epandrium wide, slightly narrower at apex, with stout scattered setae on outer face ( Fig. 12 ). Surstylus absent. Hypandrium with rounded lobes laterally; digitiform projections ventrally, with distinct setae ventrally ( Figs 12, 14, 15 ); gonocoxal apodeme projecting as narrow process just beyond anterior margin of hypandrium. Subepandrial sclerite straight on anterior margin; hypoproct long, subrectangular, with scattered setae ( Fig. 13 ). Phallus sclerotized, extending beyond hypandrium apex ( Fig. 14 ). Ejaculatory apodeme unilamellar, very short. Specimen length: 2.4 mm; wing length: 2.6 mm. Female. Unknown.

Geographic distribution. Brazil (São Paulo).

Type Material. HOLOTYPE ♂, labelled: “[ BRAZIL] Est.[ado] S.[ão] Paulo, S [erra]. Cantareira , Cantareira. 10-945[x.1945], [M.P.] Barreto col.” ( MZUSP). PARATYPE: Idem, Campos do Jordão, [morro] homem morto, 12945 (1 ♂, INPA).

Holotype condition. Abdomen in microtube with glycerin.

Etymology. From the Latin lobos (lobes), referring to the hypandrial lobes.

Remarks. Neoplasta lobata sp. nov. differs from other species mainly due to the hypoproct subrectangular and hypandrium with lateral and ventral lobes. In other species, the hypoproct is absent or if present, bilobed and hypandrium without lobes.
