Myrmoteras binghamii

Identification
This species has abundant appressed pubescence on gastral tergites. It is distinguished from the most closely related Myrmoteras tomimasai by the weaker sculpture on the dorsum of head and pronotum, and creamy to yellowish mid- and hind coxae. Legs are yellowish and much paler than the mesosoma. (See also under M. concolor and M. tomimasai.)
