Diagnosis. Each eye with two associated setae, one anterior and one posterior. Gena with two long setae. Palps dilated distally, with four setae throughout their length and two more on distal region. Female, in dorsal view, with syntergite 1+2 and tergites 3 and 4 whole. In ventral view, sternites 5 and 6 divided into two plates. Male with all tergites and sternites formed of entire plates. Male with all tergites and sternites whole.

Redescription. Head. Dorsal view—Eyes with a single lens and one seta each, posteriorly and anteriorly. Lateral view—Gena with two setae. Ventral view—Palps dilated distally, with four setae throughout their length and two on distal region. Theca as wide as long, twice as long as labella.

Thorax. Dorsal view—Notopleural suture with three setae. Thoracic ctenidium with 8 or 11 spines. Thoracic spiracle elliptical. Ventral view—Sternal plate with setae, except in medial and posterior regions. Oblique suture right-angled in female, obtuse-angled in male. Coxa I as wide as long, flattened, with setae throughout its length on anterior margin, with some setae longer than the others. Femur I longer than wide, flattened, with setae throughout its length; two setae located on distal region, longer than the others. Tibia I longer than wide, posterior margin with four rows of setae on apical portion. Basitarsus as long the following three tarsomeres combined. Coxa II triangular and with rare setae. Femur II longer than wide, with setae only along anterior and posterior margins. Tibia II longer than wide and posterior margin with two rows of setae in medial portion. Coxa III as long as wide, with rare setae. Femur III longer than wide with posterior margin with few setae along its length. Tibia III longer than wide and posterior margin with five rows of setae on apical portion.

Abdomen. Female. Tergites and sternites with few setae throughout their length. Distal margin of plates with a row of longer setae. Dorsal view—Syntergite 1+2 with few setae throughout its length. Tergite 3 to 5 whole, rectangular. Tergite 6 long, with concave posterior margin. Tergite 7 with four to seven setae on each side of the plate, anterior margin narrow and posterior margin straight. Ventral view—Sternite 1+2 narrow, with ctenidium of 30–35 spines in middle third of plate. Sternites 3 and 4 whole and rectangular. Sternites 5 and 6 divided. Sternite 7 with setae only at posterior margin. Male. Tergites and sternites with few setae throughout their length. Distal margin of plates with a row of longer setae. Dorsal view—Syntergite 1+2 subtriangular, with rounded margin. Tergite 3 to 5 whole, rectangular. Tergites 4 and 5 with two setae longer than the others on posterior margin. Tergite 6 short and narrow, with a row of six long setae at posterior margin. Anal plate with setae only on posterior margin. Ventral view—Sternite 1+2 with ctenidium of 30–40 spines covering most of posterior margin. Sternites 3 and 4 rectangular. Sternite 5 long, with rounded margin and a concavity at medial posterior margin; setae on lateral margin more sclerotized than the others and of different sizes.
