9. Glyphidops (Glyphidops) xanthopus (Schiner)

Nerius xanthopus Schiner, 1868: 247 . Type locality: “Süd-Amerika” ( Venezuela). Type? sex? [NMW]. Glyphidops xanthopus ; Enderlein, 1922: 151.

Glyphidops (Glyphidops) xanthopus ; Aczél, 1961: 315.

Diagnosis. Arista white pubescent at base and brown and bare on distal two thirds. Frontal vitta yellow. First flagellomere length 2.5 times width. Pleuron higher than long. Fore coxa without anterolateral seta. Femora with one yellow distomedial ring, mid and hind femora with one more ring, paler. Fore femora with anteroventral setae throughout and posteroventral setae only on distal half. Mid femur anteriorly with one seta (Hendel, 1933).

Comments. Nerius xanthopus was originally described by Schiner (1868) in his monograph on Diptera of the Novara expedition. Last redescription was by Hendel in 1933, based on material at the Naturhistorisches Museum Wien (NHM), which is also where the type material is located. Since then, no new specimens of N. xanthopus have been discovered and we were unable to access any type specimens or photographs. We provide a simple diagnosis here based on the original description by Schiner (1868), and subsequent redescription by Hendel (1933).

Distribution. Mexico, Guatemala, Venezuela, Surinam, Peru ( Steyskal, 1968).
