Vein r-m placed just before basal third of cell dm. Vein dm-cu straight. Halter brown with middle part of stem yellow. Legs ( Fig. 163 ). Coxae dark brown to black, gray pruinose. Trochanters yellow. Femora brown with base and apex yellow, entirely gray pruinose posteriorly. Tibiae yellow, gray pruinose. Tarsi dark yellow to brown, except fifth tarsomere darker or entirely black. Pulvilli yellow. Abdomen. ( Fig. 166 ). Dark brown to black, gray pruinose on tergite 1, almost entirely on tergite 2, except for two brown pruinose spots anterolaterally and a small spot medially; gray pruinose posterolaterally on tergites 3–5; tergite 1 with three stout bristles laterally. Tergite and sternite 6 as in Fig. 167 . Sternite 6 ( Figs 168, 169 ) with three sclerotized spine-like projections, basal one longest. Syntergosternite 8 dark brown to black, shorter than tergite 5, gray pruinose ( Fig. 166 ) and with large membranous area ( Fig. 170 ). Terminalia. Epandrium and surstyli ( Fig. 171 ) yellow. Surstyli ( Figs 171–172 ) asymmetrical. Left surstylus strongly developed, apex curved outward, about 2X longer than right surstylus, with basal lobe; lateral view as in Fig. 173 . Right surstylus with acute apex in lateral view ( Fig. 174 ). Subepandrial sclerite as in Fig. 175 . Right gonopod longer than left one ( Fig. 176 ). Phallic guide ( Figs 177–178 ) with one additional bifid process; dorsal view as in the Fig. 179 . Phallus with inconspicuous subapical spicule ( Fig. 180 ). Ejaculatory apodeme as in Fig. 181 . Female unknown.

Variation (paratype). Body length 4.4 mm. Wing length 4.6 mm. Sternite 6 with basal protuberance longer than in the holotype specimen.

Type Material. HOLOTYPE ♂: “ BRASIL, PI[auí], Guaribas, Parque Nacional Serra das Confusões, Andorinha, 515 m, 09°08'27.8"S, 43°33'42.1"W ” “Armadilha de Malaise, 01–10.ix.2013, J.A. Rafael, F. Limeirade-Oliveira & T.T.A. Silva cols [collectors]”. “ Holotype ♂, Elmohardyia rosalinae Marques & Rafael ” ( CZMA). PARATYPE: idem, 20–30.ix.2013 (1♂ INPA).

Holotype condition. Left wing detached, mounted on microslide. Terminalia

placed in microvial with glycerin.

Etymology. The specific epithet is a patronym honoring Rosalina da Silva, a great friend and a “second mother” of the first author.

Distribution. Brazil: Piauí (Caatinga Biome).

Discussion. Elmohardyia rosalinae sp. nov. is close to E. valida Menezes & Rafael due to sternite 6 with thorn-like protuberances, left surstylus with outward curved apex and longer than right surstylus, and by the similar shape of the phallic guide. Elmohardyia rosalinae sp. nov. differs from E. valida by tergites 3–5 being gray pruinose posterolaterally (only on tergite 5 in E. valida ), and by sternite 6 with three protuberances (only two in E. valida ).
