Description

Worker

Antennal scrobes smooth and shining with slight minute surface rippling. Propodeal declivity smooth and shining, the area reduced in size compared to other species, its borders barely raised; posterior face of petiolar node smooth and shining, merging above with the similarly unsculptured dorsum. Head relatively large and broad; eyes more protrusive in frontal view than in other species. Mesosoma relatively short and dorsally inflated—its profile with an almost semicircular dorsal arc in lateral view. Humeral epaulets well developed. Petiole relatively short and broad in lateral view, approximately as long as high, rounded above in profile. (Holotype; smallest available specimen, largest available specimen): TL (ca): 4.4, 4.4, 4.8; HW: 1.11, 1.07, 1.19; HL: 1.01, 0.99, 1.11; CI: 104, 108, 107; EL: 0.21, 0.20, 0.23; SL: 0.64, 0.62, 0.66; SI: 57, 58, 55; PW: 0.79, 0.74, 0.82; WL: 1.25, 1.25, 1.33; petH: 0.72, 0.65, -., petW: 0.45, 0.45, 0.49; GW 0.80, 0.77, 0.88.
