Description

Worker

Borowiec and Salata (2022) - (partly after Baroni-Urbani 1978). Small to large: HL: 1.21; HW: 1.29; SL: 0.79. Color. Whole body from rusty yellow to greyish brown, antennae and legs yellow . Head. As long as or slightly wider than long, widest in anterior third then softly converging posterad, occipital corners rounded, occipital margin shallowly concave. Clypeus very short, transverse, with softly rounded anterior margin armed with a row of slightly angulated denticles, each denticle at apex with a minute spine. Clypeus with diffused longitudinal striation, surface microreticulate but shiny, with a pair of long erected setae in the middle and few short erected setae laterally. Mandibles long and narrow, with striated sculpture, inner margin with 5 large, bidentate apically teeth, two or three large unidentate teeth behind last bidentate tooth and small tooth close to apex. Anterolateral corners of head often prolongate in denticle or spine. Head with very distinct granulate sculpture, frons sometimes with distinct longitudinal striation, interspaces appear irregular and slightly dull, with moderately long and moderately dense subdecumbent pubescence, erected setae absent, ventral side of head mostly with short subdecumbent pubescence and few erected setae. Scape very short, 0.6 times as long as width of head, stout, slightly widened from base to apex, but apically slightly constricted, its surface distinctly microreticulate and slightly dull, with short subdecumbent to suberect pubescence, ventral surface also with few erect setae. Funicular segments transverse, stout, only first segment 1.4 times as long as wide, segments 2 longer than wide, segments 3-6 short, slightly wider than long, the rest of funicular segments distinctly broader than six basal segments. Eyes minute but well visible, composed with more than four ommatidia. Mesosoma. Elongate, 2.4 times as long as wide, dorsally and laterally with fine microreticulation with sparse punctuation, propodeum on sides with oblique and longitudinal striation, interspaces shiny, with short and sparse appressed to decumbent pubescence , surface from slightly shiny to slightly granulate. In lateral view pronotum slightly convex, mesonotum and propodeum straight, posterior face of propodeum oblique, mesonotal suture distinct. Mesosomal dorsum lacking erected setae. Waist and gaster. Petiole in form of cubicous node broadly connected with gaster, surface sparsely punctate, interspaces slightly irregular but shiny, covered with sparse and short pubbescence in anterior half and longer subdecumbent to decumbent, longer pubescence basally. Gaster longer than mesosoma, tergites with micropunctation and fine microreticulation, surface shiny, covered with moderately long and moderately dense subdecumbent pubescence not covering surface and few to several longer standing hairs. Legs. Stout, tibiae distinctly widened from base to apex, surface covered with moderately long and sparse subdecumbent to decumbent hairs, erected setae absent sometimes few additional suberect hairs present.
