Length 4.4 mm. LW/MWW = 3.2. LTC/LFC = 1. Membrane hyaline, almost entirely covered with microtrichia, except for cells bc, basal two thirds of c, basal three quarters of sc, basal one third of r1, br, bm, basal half of cup and basal one third of anal lobe without or with very sparse microtrichia. Vein r-m placed in the basal third of cell dm. Vein dm-cu straight. Halter brown, except for the yellow stem. Legs. (Fig. 130). Coxae brown, gray pruinose. Trochanters yellow.

Dark brown to black, gray pruinose on tergite 1, almost entirely gray pruinose on tergite 2, except for a small brown pruinose spot, and tergites 3–5 gray pruinose only posterolaterally; tergite 1 with three small black bristles laterally. Tergite and sternite 6 as in Fig. 134. Sternite 6 (Fig. 135) with two symmetrical subapical projections. Syntergosternite 8 dark brown to black, slightly shorter than tergite 5, gray pruinose (Fig. 133) and with longitudinal membranous area, longer than wide (Fig. 136). Terminalia. Epandrium and surstyli yellow (Fig. 137). Surstyli (Figs 137–138) asymmetrical. Left surstylus longer than right surstylus, curved inward, with basal lobe (Fig. 138); lateral view as in Fig. 139. Right surstylus curved inward; lateral view as in Fig. 140. Subepandrial sclerite as in Fig. 141. Right gonopod slightly more developed than left gonopod (Fig. 142). Phallic guide (Figs 143, 144) with two additional processes, being lateral one bifid; dorsal view as in Fig. 145. Phallus with subapical spicule (Fig. 143). Ejaculatory apodeme as in Fig. 146. Female unknown.
Variations (n = 4). Body length varying from 3.8–4.4 mm (three paratypes were not measured prior to dissection).
Type Material. HOLOTYPE ♂: “ BRASIL, RN [Rio Grande do Norte], Parnamirim, Est.[ação] Exp.[erimental] Rommel Mesquita de Faria” “ 05°55'45"S, 35°11'21"W, 18–25.ii.1995, Plant.[ação] Coco Anão” “ Holotype ♂, Elmohardyia potiguar Marques & Rafael ” (INPA). PARATYPES: same data as holotype (2♂ INPA); idem, 25.ii–04.iii.1995 (1♂ INPA); idem, 11–18.iii.1995 (2♂ CZMA).
Holotype condition. Specimen previously stored in 70% ethanol. Wings damaged. Tarsal segments of right mid leg missing. Terminalia placed in microvial with glycerin.
Etymology. The specific name ‘potiguar’ refers to a term traditionally used in Brazil for the native inhabitant of the Rio Grande do Norte state where the specimens were collected.
Distribution. Brazil: Rio Grande do Norte (plantation area surrounded with Atlantic Forest).
Discussion. Elmohardyia potiguar sp. nov. is close to E. limeirai sp. nov., due to the left surstylus with inward curved apex, sternite 6 with two subapical protuberances, membranous area longer than wide, and by the phallic guide with two additional processes. Elmohardyia potiguar sp. nov. differs from E. limeirai sp. nov. by the stouter left surstylus (thinner in E. limeirai sp. nov.), right surstylus somewhat parallel sided (base wider than apex in E. limeirai sp. nov.), and short but distinct left gonopod (not developed in E. limeirai sp. nov.).
