Polyrhachis simpla

Identification
A member of the Polyrhachis continua species group in the subgenus Myrma

Polyrhachis simpla is very similar to Polyrhachis spinifera and Polyrhachis sericeopubescens, however, it differs from both in having the lateral margins of the pronotal dorsum virtually flat, while they are distinctly upturned in the other species. Also, the lateral margins of mesonotum distinctly converge posteriorly in P. simpla, while they are subparallel in both P. spinifera and P. sericeopubescens. (Kohout 2013)
