Eusphinctus furcatus

In Thailand this species has been collected in evergreen forests (Jaitrong et al., 2016).

Identification
Eusphinctus furcatus is similar to Eusphinctus taylori Forel, 1900 in general appearance as they share the pygidial apex deeply notched (as seen from above), 11-segmented antenna, reddish brown body and swollen mesosoma. However, E. furcatus is easily separated from E. taylori by the following conditions: body larger (WL 1.68-1.78 mm in S. furcatus while WL 1.27 mm in E. taylori); petiole longer than broad (broader than long in E. taylori); body color darker (deep reddish brown in E. furcatus while light reddish brown in E. taylori). (Jaitrong et al., 2016)
