group, as can be inferred both from the sexual characters and from the external morphology (special color pattern, four protrusions on anterior margin of labrum, morphology of the aedeagus, shape of the male sternite IX and the female sternite VIII). This new species is distinguished from other species of this group by the shape of female sternite VIII and the morphology of the aedeagus (more slender dorsal plate of the median lobe; slender parameres; three distinctive sclerotized spines in the internal sac). Based on the similar morphology of the aedeagus,
