Face shining with few scattered punctures, punctures stronger between lateral ocelli and on occiput; scape with few long, erect setae ventrally; flagellomere I L/W 2.5–3.1; lower rim of antennal socket not sharp or carinate below; basal half of clypeus shining, impunctate, apical half with several irregularly spaced, broad, shallow punctures and long apically directed setae; gular carina not abruptly raised anteriorly, not visible below mandibular condyle in full lateral view; mandibles with several long, stout amber-colored setae on outer surface. Mesosoma. Strongly punctured, sparsely clothed with medium to long erect or suberect setae; anterior face of pronotum shining medially, nearly impunctae, lateral surface strongly punctate; mesonotum with punctures smaller, more closely set anteriorly; mesepisternum with strongly raised, ridge-like elevation below anterodorsal protuberance; propodeum with dorsal sulcus strongly impressed, shining, raised area laterad of sulcus finely reticulate, impunctate except for small lateral area, posterior declivity sharp, carinate, sulcus between declivity and posterior transverse carina smooth, shining; posterior propodeal face separated from lateral face by lateral diagonal carina meeting posterior carina dorsally, obsolete before posterior rim.
