Ale-Rocha, R. & De Carvalho, C. J. B., 2003, Neohybos gen. nov. (Diptera, Empidoidea, Hybotinae) from the Neotropical Region, Zootaxa 387, pp. 1-16 : 12-15

Neohybos luridus (Bezzi) comb. nov. ( Figs. 19–25 , 30 )

Hybos luridus Bezzi, 1909:310 ; Collin, 1933:28 (citation); Smith, 1967:11 (catalogue), Rafael & Ale­Rocha, 1995:530 (revision).

Diagnosis. Flagellum with one dorsal short bristle; body black with pruinose thorax and shiny abdomen; scutum with gray pruinescence inserted with dorsocentral strip of brown pruinescence, posterior half of scutum and inferior half of mesopleuron with whitish tomentum; scutellum with gray pruinescence; acr and dc short, scattered, acr uniserial; wing smoothly brownish to hyaline with brown stigma; legs black except base of tibiae, tarsomeres 1–2 yellow, tarsomeres 3–4 brown.

Species reviewed by Rafael & Ale­Rocha (1995) with designation of the female lectotype and figures of female terminalia and wing. In the mentioned work, the male specimen used by Bezzi (1909) in the original description was not studied and it is probably lost. A series of female specimens from Ecuador were examined in this work. Two male specimens were associated with the females by general characters. The male terminalia was studied and the illustrations presented for the first time.

Male terminalia ( Figs. 19–25 ): bristles sparse and slender; right hypandrial lobe as long as half of length of hypandrium; dorsal bridge incomplete, right hypandrial arm short; left postgonite almost triangular; right epandrial lamella tapered distally in lateral view; left epandrial lamella with bilobed apex; right bacilliform sclerite with large process with truncate apex bearing black robust short bristles; phallus with large and robust spine­like process distally.

Distribution. Bolivia, Ecuador (new record).
