(Figs 34–42, 84)
Etymology. The species name is a patronym in honor of Professor José Augusto Silva Oliveira for stimulating research and other contributions to the Universidade Estadual do Maranhão.
Diagnosis. Predominantly yellow. Membranous area between segment 8 and terminalia inflated and longer than length of tergite 8; cercus triangular, slightly tapered distally in lateral view; gonocoxal apodeme prolonged; phallus with a distal membranous area, covered with tiny dark spicules, and distally with sclerotized hook-shaped process.
Holotype ♂ (Fig. 34). Body length 2.4 mm; wing length 1.8 mm.
Description. Head (Fig. 34). Black; clypeus, palpus and proboscis light yellow; anterior ocellus larger than posterior ones. Eye black, iridescent, contiguous in middle of face, with tiny, very inconspicuous setulae. Frons brown, about 2.0X longer than wide, covered with dark yellow to light brown pubescence; occiput with light yellow setae, sparse yellowish-brown pubescence, dense only at eye margin. Antenna light yellow, except for paler postpedicel and stylus with light brown appearance in lateral view; scape short, about half-length of pedicel; pedicel about 2.0X longer than scape; postpedicel about 2.0X longer than maximum width; stylus longer than postpedicel; scape, pedicel and postpedicel with tiny, very inconspicuous setae. Clypeus with whitish pubescence; palpus with 2–3 distally arranged light yellow setae; labellum with short, dense pale yellow setae. Proboscis with short setae located distally.
Thorax (Fig. 34). Pale yellow, except for small brown details in following areas: i) dorsomedial region of prothorax, and ii) anterior to notopleuron. Thorax about 2.0X longer than wide; mesonotum with short, weak and sparse setae, except notopleuron with one longer and stronger seta.
Legs (Fig. 34). Pale yellow to yellow. Foreleg with C1 about ¼ longer than F1, F1 about ¾ longer than T1, t1 equal in length. Mid and hind legs with coxae, femora, tibiae and tarsi of equal length. F1 with Ff=8/23/16/5+1, black denticles arranged in two parallel linear rows, located on distal ⅔, closer to each other distally, bordered by two rows of strong setae. T1, ventrally arched, ventral surface with two rows of black, spine-like setae (17–18), T1 with strong, spine-like seta located on ventrodistal surface. All legs with short, sparse pale yellow to dark yellow setae on coxae and femora, dense on tibiae and tarsi, except for slightly longer setae distally on C1; T1 with 1 row of setae on posterodorsal surface on distal ½.
Wing (Fig. 35). Membrane slightly yellowish, except slightly darker radial sector region, veins yellowish; R 2+3 long and straight, gently curved towards distal C vein, ~ 0.7 distance between end of R 1 and R 4; bifurcation of R 4+5 acute (~60°); distance from bifurcation of R 4+5 to bifurcation of M 1+2 about 2.0X length of R 4; R 5 about ¾ length of M 1 and subequal to size of M 2. R 5 and M 1 veins converging preapically but diverging distally; cell bm + dm short, terminating at level of R 1, about 2.0X longer than cell br. Halter pale yellow.
Abdomen (Fig. 34). Long and slender. Tergites brown to dark brown, except tergite 7 pale yellow; distinct setae only on posterior margin. Sternites yellow with a few scattered setae, stronger on posterior margin. Membranous area between segment 8 and terminalia inflated, longer than length of tergite 8.
Male terminalia (Figs 36–42). Entirely brown. Cercus subtriangular, tapered distally in lateral view (Figs 37, 40); left and right cercus distinctly separated anterodorsally; cercus setose externally. Epandrium narrowly rounded distally, with short setae near dorsal margin (Figs 36, 37). Surstylus subquadrate distally (Figs 40, 41). Hypandrium subtriangular (Fig. 39), sclerotized with short, scattered setae in ventral view. Gonocoxal apodeme long, projected beyond anterior margin of hypandrium, longer than length of terminalia (Figs 37, 39, 42). Subepandrial sclerite with subquadrate anterior projection and rounded median posterior process, with distal setae in dorsal view (Fig. 41). Phallus cylindrical, strongly sclerotized, except distal membranous area covered by tiny dark spicules and distally with sclerotized hook-shaped process; phallus extended beyond hypandrium distally (Fig. 42). Ejaculatory apodeme long with laterally flattened unilamellar plate, ⅔ length of gonocoxal apodeme (Figs 37, 42).
Female. Unknown.

Variation. Male (n = 4). Body length 2.4–3.2 mm, mean 2.8 mm; wing length 1.7–1.8 mm, mean 1.75 mm; wing width 0.4–0.6 mm, mean 0.5 mm.
Geographical record. Brazil (Maranhão).
Remarks. Hemerodromia joseaugustoi sp. nov. appears to belong to the same group of species that includes H. joanae sp. nov., H. lamellata Câmara, Plant & Rafael, 2014, H. longilamellata Câmara, Plant & Rafael, 2014, H. megalamellata Câmara, Takiya, Plant & Rafael, 2015 and H. membranosa Câmara, Takiya, Plant & Rafael, 2015 in having the membranous area between segment 8 and terminalia long or nearly as long as tergite 8, and long gonocoxal and ejaculatory apodemes. Hemerodromia joseaugustoi sp. nov. is similar to H. longilamellata in having the cercus subtriangular, slightly tapered distally in lateral view and epandrium narrowly rounded distally. Hemerodromia joseaugustoi sp. nov. differs from H. longilamellata by subepandrial sclerite with rounded median posterior process (subepandrial sclerite with pointed median posterior process in H. longilamellata); phallus sclerotized with distal membranous area covered by small, dark spicules and hook-shaped sclerotized process distally (phallus sclerotized, extended slightly beyond apex of hypandrium, with apically membranous, narrow area without spicules; without hook-shaped distal process in H. longilamellata).
Comments. Specimens of H. joseaugustoi sp. nov. were collected in Cândido Mendes in February and May and in Centro Novo do Maranhão from December to February.
