Redescription of Neorhinotora Lopes

Head. Wider than long, vertex deeply excavated, compound eyes prominent. Two reclinate orbital setae, lower seta inconspicuous; one inner vertical seta; one outer vertical seta. Ocellar triangle shiny. Gena well developed, as wide as or wider than compound eyes; one subgenal seta as developed as oral vibrissa; pale setulae on its posterior half; pruinescence fine, silvery, also bordering compound eye. Flagellomere 1 globose, slightly flattened laterally; arista preapical. Labellum small; prementum with sparse fine setulae at the base of its posterior surface; palpi narrow, with numerous long and fine setulae.

Thorax. Two postsutural dorsocentral setae; one presutural intra-alar seta; one postsutural supra-alar seta; one postpronotal seta; two postalar setae; two notopleural setae; pruinescence on scutum sparse, fine, with variations of silver, golden and copper. Scutellum well developed; one lateral seta; one apical seta, sometimes with base prominent; well-developed spines absent ( N. fonsecai has lateral and apical prominences resembling spine rudiments). Pleura with sparse pruinescence; katepisternum predominantly shiny with two strong higher setae; setulae fine, pale, mainly on ventral surface.

Legs. Ventral apex of tibia and tarsus covered with golden setulae. Fore femur swollen (only slightly swollen in N. fonsecai ); numerous strong setae on the ventral surface. Fore tibia with a row of strong setae on the ventral surface. Mid- and hind coxa with one distinctive anteroventral seta each. Mid femur with two rows of short dark setae on the ventral surface. Mid tibia with one short and distinctive anteroventral apical seta. Mid tarsomeres 1–4 with strong, short, anteroventral and anterodorsal setae. Hind femur with one long and strong dorsal seta on distal quarter. Hind tibia with one short and strong apical anterodorsal seta. Hind tarsomeres 1–4 with strong and short anteroventral and anterodorsal setae.

Wing. Membrane smoky, with dark spots only around cross-veins r-m, dm-cu, between R2+3–R4+5 fork and R1 fork, on distal extremity of R4+5 and M; supernumerary veins in cell r1 absent (in N. diversa supernumerary veins are present and membrane is fully spotted, with darker and paler regions).

Abdomen. Setulose, lateral setulae longer. Male genitalia: Epandrium with strong setulae along its entire length. Surstylus well developed, setulose. Bacilliform sclerite narrow and laterally connected to the hypandrium. Cerci fused to each other and fused by their base to epandrium. Hypandrium fused to pregonites and postgonites, free from base of phallus and connected by the anteroventral margin to the phallapodeme. Pregonite reduced, strongly setulose. Phallapodeme thin and laterally flattened; base anteroventrally extended backwards to connect to the hypandrium, base dorsally connected to the phallus. Postgonite slightly projected ventrally, with small setulae on apex and some sparse setulae along its surface. Phallus more sclerotized on the laterodorsal portion, apex narrow. Ejaculatory apodeme slightly dilated basally and with little protuberances; spermatic sac inconspicuous, laterally positioned. Female terminalia: Ovipositor short. Hypoproct with numerous setulae; cerci free from each other, wide and flattened, 1-segmented, with numerous setulae. Epiproct with rounded apex; setulae long and strong. Sternite 7 and tergite 7 free from each other. Sternite 8 weakly sclerotized; limit with tergite 8 scarcely visible. Two spherical spermathecae, strongly sclerotized, with surface covered with small protuberances.
