Brown col., varzia, litter (1W) (MCZ35423) [MCZC] [examined]. Paratypes: same data as holotype (1Q) (MCZ35423) [MCZC] [examined]; (1W) (MZSP67451) [MZSP] [examined]. Diagnosis. Regular and longitudinal striae on head dorsum, parallel towards posterior margin, interspaces between thicker striae filled with thinner striae; mesosoma covered with striae of variable thickness assuming multiple directions, interspaces indistinguishable; transverse on mesonotum; dorsal margin of mesonotum straight; lateral of pronotum and mesepisternum with longitudinal striae in part continuing transversely on propodeum dorsum and in part continuing on propodeal spine; dorsal margin of petiole discontinuous; petiole ventral surface entirely covered with transverse striae; regular to irregular and mostly transverse striae on dorsal surface of petiole, interspaces indistinguishable; subpostpetiolar process striate; profemur posterior surface and protibia extensor surface entirely striate; long striae on tergum of first gastral segment; sternite striation weakly marked, covering all basal region; branched setae with multiple branches arising from the main axis; branches relatively long, subequal-sized; branched setae mainly in posterior and lateral regions of head, mesosoma, petiole and postpetiole.
