Polyrhachis vindex

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

Kohout (2008) - Polyrhachis orsylla is undoubtedly closely related to Polyrhachis vindex. The species differ in the form of the pronotal spines which are shorter and only slightly longer than their basal widths in P. orsylla and about twice as long as their basal widths in P. vindex. Also, the sculpturation of pronotal dorsum in P. orsylla is distinctly finer, almost vague in some specimens, while in P. vindex it consists of rather distinct, more-or-less regular, striation.
