Scape and pedicel twice as wide as ﬂagellomeres, scape with one and pedicel with two apical rows of setae. Flagellum with 14 cylindrical segments, covered by hairs as long as ½ ﬂagellomere diameter. Face setulose. Only three apical segments of palpi visible; antepenultimate and penultimate knoblike; apical long, slender, straight, its length approximately the combined length of preceding two palpomeres.
Thorax: Mesonotum with few long lateral and scattered shorter setae. Anterior parapsidal suture distinct. Scutellum with 6 long setae and sparse short ones. Laterotergites and mediotergite bare.
