Comments. REITTER (1880) based this species on an unknown number of specimens from -Mysol- (=Misool). The E. Reitter s collection of exotic scaphidiines was puchased by R. Oberthür ( HORN et al. 1990), and the bulk of the R. Oberthür collection is housed in the MHNN. Thus, Ihave assumed that also the type material of B. longipes is in the Paris collection ( LÖBL 2018), although not found there while my visit. ACHARD (1924) stated to have received from R. Oberthür the type (le type) and transferred the species to Heteroscapha Achard, 1914 (a junior synonym of Bironium ; see LÖBL 1971). As the number of original specimens is unknown, ACHARD (1924) designated the lectotype by inference, and this specimen is in the NMPC. The present concept of B. longipes (Reitter) is based on this specimen examined previously and redescribed in LÖBL (1989), though re­examined for the present study. It complies with the original Reitter s description.

The followings characters are here newly given: Elytra with basal striae interrupted at level of humeral areas; male tarsomere Iabout as wide as half of protibial apex, shorter than tarsomeres II and III combined; tarsomeres III not lobed, with long, not flattened ventral setae; gonocoxite without gonostyle ( Fig. 20 ).
