Redescription. Male. Length: body, 6.5–7.0 mm; wing, 6.5–7.0 mm. Head. Vertex yellow, setation yellow. Upper frons reddish yellow. Flagellomeres 1–3 brownish on outer margin, paler ventrally on inner margin; flagellomeres 4–8 dark brown to black; eighth flagellomere five times length of seventh flagellomere (Fig. 2). Palpus (Fig. 67) reddish yellow, elongate; basal segment cylindrical, as long as wide; apical segment oval, 1.8–2.3 its width, 1.6–4.0 length of basal segment, both with pale hairs. Thorax (Figs. 8, 60). Entirely reddish yellow, postpronotal lobes and notopleural strip slightly contrasting with color of scutum. Scutum and scutellum orange, with brownish pilosity. Legs. Mostly reddish yellow, except for brownish tarsomeres (basitarsus only distally), mid and hind trochanters, hind coxae and hind tibiae dark brown to black. Wing as in Fig. 66. Halter yellow. Abdomen. Reddish yellow, with black transverse bands on tergites; tergites 2–4 with one small macula, mostly yellow; sternites weakly sclerotized. Male genitalia (Figs. 9–14). Distal margin of gonocoxite rounded (Fig. 9); inner plate with two acuminate projections distally (Fig. 10). Gonostylus wider on basal half, with a small rounded inner projection (Figs 12–13). Ejaculatory apodeme truncate basally (Fig. 9). Distal margin of lateral projections of phallus rounded (Figs. 9–10). Cercus more or less oval (Fig. 14).
Female. Differs from male as follow. Length: body, 6.0– 7.5 mm; wing, 6.0–8.0 mm. Abdomen. Tergites mostly black, except for tergites 7–8; sternites weakly sclerotized, 1–4 with a small black macula. Female genitalia (Figs. 15–20). Tergite 8 wide, more or less rectangular, rounded anteriorly. Sternite 8 quadrate, narrowing towards apex (Fig. 19); gonapophyses slightly sclerotized, strongly bilobed, rounded apically. Tergite 9 more or less rounded laterally (Fig. 16). Genital fork with anterior arm rounded at extreme base (Figs. 15–17); membranous lobes of genital fork wide, covering nearly entire distal half; projection of posterior margin short, inner margin oblique; margin between posterior projection with a more or less oval medial incision; genital opening large, circular, a few microtrichia on bursa. Three spermathecae present (Fig. 56), lateral ones with short ducts, more sclerotized posteriorly, with a distinct rounded valve near middle of duct; spermathecal capsules circular, helicoid, with two coils, strongly sclerotized (Fig. 18). Cercus with first segment moderately compressed, basally wider than distally; first segment of cercus more than 1.5 times length of second segment.
Geographic distribution. Brazil (states of Mato Grosso, Minas Gerais, Rio de Janeiro, Santa Catarina and São Paulo) (Fig. 92).
Comments. This species shows variation in the hind leg color. The specimens of the type series of Arthropeina fulva, according to the original description, and some of the identified specimens have dark brown to black hind coxa, while specimens from Teodoro Sampaio (State of São Paulo), Presidente Olegário (State of Minas Gerais) and Chapada dos Guimarães (State of Mato Grosso) have the hind coxae yellow to reddish yellow. This difference does not seem significant to indicate that this set of specimens are not conspecific. Structures of female genitalia and spermatheca do not show substantial differences. Most specimens from this species studied here, however, are females. Maybe males from these areas may show more significant differences. At present, we decided to treat these specimens as conspecific and the differences in color as intraspecific variation.
