Proguithera drescheri ( Wygodzinsky, 1966)

( Figs. 30–33 )

Guithera (Proguithera) drescheri Wygodzinsky, 1966: 127 , 130. Holotype (♀): Indonesia, West Java, Tangkuban Perahu , RMNH.

Proguithera drescheri: Dispons (1970: 220) (generic placement); Rédei (2004: 314) (in key), Ishikawa & Naka (2016: 192) (in key).

Guithera (Proguithera) drescheri: Maldonado-Capriles (1990: 102) (catalogue, distribution).

Diagnosis. Recognized within the genus by the following combination of characters: pronotum along midline 0.9 times as long as its width across humeral angles, with deep median longitudinal sulcus ( Fig. 31 ); anteroventral series of fore femur composed of not more than 20 spine-like setae; fore wing with cross vein between M + Cu and submarginal vein basad of discal cell well developed, slightly oblique, inserted some distance from basal angle of discal cell ( Fig. 33 , white arrow); Rs vein clear; discal cell stout, shorter than M extending from its apex ( Fig. 30 ).

Type material examined. Holotype (♀): INDONESIA, West Java, Tangkuban Perahu , S6°45′47″, E107°35′58″, 4000–5000 ft, Mar. 1937, F.C. Drescher leg. ( RMNH).

Distribution. INDONESIA: West Java.

Remarks. This species can be easily recognized by the structure of the pronotum, armature on the fore femur, and fore wing venation. Its type locality was recorded as ‘G. Tangkoeban Prahoe, 4000–5000 Voet, Preanger, Java’ on the data label of the holotype, and ‘ Java: Dreangar, Tangkoeban Prahoe’ in the original description. The locality is the Tangkuban Perahu volcano in West Java, Indonesia. The handwritten “P” on the data label looks like “D”, which probably caused Wygodzinsky (1966) to write “Preanger” instead of “Dreanger”. The male of this species remains unknown.
