Body 1.9 cm long, light brown, not narrow or elongated; profile curved. Legs and ventral side sparsely covered with bristles ( Fig. 2 View Fig ).

Head. In dorsal view, including eyes, about twice as wide as long; slightly wider than anterior margin of pronotum. Antenna small, not extending past clypeus; with six segments. Clypeus in dorsal view rounded, bulbous; profile rounded. Rostrum reaching base of metacoxae.

Thorax. Pronotum in dorsal view about half the length of mesonotum. Metanotum very small compared to pronotum and mesonotum. Apex of fore wing reaching third abdominal segment; hind wing reaching third abdominal segment ( Fig. 2 View Fig ). Legs and ventralregion of thorax with sparse setae. Profemur ( Fig. 3A View Fig ) with posterior tooth long, sharp, curved forward slightly; about 3× as long as wide at base. Accessory posterior tooth small, blunt. Intermediate tooth present. Diastema betweenintermediate tooth (itf) and posterior tooth (ptf) wide; diastema between itf and ptf longer than length of ptf. Profemoral comb with 7 teeth.Apical toothof comb slightly blade-like; pointed. Protibia ( Fig. 3A View Fig ) withwell-developed blade; untoothed; with one pointed, well-developed, preapical tooth. Apical tooth about 1.5× as long as width of base; separated from previous tooth by deep notch. Protarsus ( Fig. 3A View Fig ) two-segmented; apical tarsomere elongated; protarsal claws of unequal size. Mesotibia ( Fig. 3B View Fig ) without lateral spines or protrusions; with five apical spines, one much smaller than the others. Mesotarsus two-segmented; apical tarsomere elongated; mesotarsal claws of unequal size. Metatibia ( Fig. 3C View Fig ) with four large apical spines and two or three much smaller spines situated slightly higher up on leg and between the larger spines. Hind tarsus ( Fig. 3C View Fig ) two-segmented, apical tarsomere elongated; metatarsal claws of unequal size.

Abdomen ( Fig. 2 View Fig ). Short, cylindrical in cross section; in dorsal view, lacking distinct waist; with few ventral setae. Abdominal tergites without transverse rows of setae; tergites 6–10 with sparse hairs; tergite 7 with dark spot either side of midline. Sternites three-quarters the width of abdomen proximal to thorax, tapering distally to onetenth the width of abdomen; covered with white tomentum. Sternite 1 lacking median protruberance. Sternite 10 of male with a single protrusion, pointed apically.
