Diagnosis. This species can be distinguished from micromeria Bartalucci , which it most closely resembles, by the bicolored clypeus and the presence of a tyloid on flagellomere VIII.

Male. Body length 4 mm. Head: inner eye margin slightly emarginate; flagellomere I as long as broad; flagellomeres II and XI twice as long as broad, flagellomeres VIII–X each with one tyloid; clypeal apex broadly truncate. Mesosoma: hindleg unmodified. Metasoma: segment 1 longer than broad; sternum VIII thickened apex broadly triangular, slightly longer than broad, apical margin spinose. Genital capsule ( Figs. 5 , 15, 25 ): gonocoxa broadest basally, narrowed medially, broadly rounded apically in dorsal view; aedeagus narrow, about 10x as broad as long, apical lobes narrowly separated; volsella dorsal lobe extending diagonally from behind dorsal lobe of gonocoxa toward paramere, largely obscured by paramere and gonocoxa in lateral view; paramere basally strongly tapering toward base, 4x as long as broad, apical lobe about twice as long as broad in ventral view. Punctation: body with dense small, contiguous punctures. Vestiture: silvery. Coloration: head, mesosoma and metasoma black, with pale yellow to whitish markings; clypeus white, with black dorsal margin; mandible white, with dark apex; underside of scapal apex white; whitish band along inner eye margin; flagellum bicolored, top black, underside orange; small whitish spot behind eye near vertex; pronotum with transverse whitish band along posterior margin and ventral whitish spot; tegula and wing vein bases white; tarsi, trochanters, palps and tibial spurs whitish; tibiae and femora partly whitish; paramere apical lobe whitish.

Female. Unknown.
