Genus Proguithera Wygodzinsky, 1966

Proguithera Wygodzinsky, 1966: 129 (new subgenus of the genus Guithera Distant, 1906), upgraded to the generic rank by Dispons (1970). Type species: Guithera (Proguithera) drescheri Wygodzinsky, 1966 , by original designation.

This small genus in the tribe Leistarchini of the subfamily Emesinae to date includes only the following two described species from the Oriental and Palaearctic regions ( Rédei 2004): Proguithera drescheri ( Wygodzinsky, 1966) , from Indonesia, and P. inexpectata Rédei, 2004 , from Afghanistan. The diagnostic characters of the genus within the Leistarchini are: venter of head lacking spine-like setae ( Figs. 8, 10 ); interocular furrow strongly curved backward far beyond level of posterior border of eyes ( Figs. 7, 9 ); pronotum covering mesoscutum but not scutellum ( Figs. 2, 4 ); profemur lacking penicillate process, but with accessory series ( Figs. 15–16 ); posteroventral series of profemur beginning at or near from the base of the segment ( Figs. 15–16 ); protarsus two-segmented ( Fig. 19 ); and pterostigma reaching tip of forewing ( Fig. 11 ). Wygodzinsky (1966) provided a detailed description of this genus (as a subgenus of the genus Guithera).

The following new species is the first documented occurrence of Proguithera from Japan.
