Diagnosis. Eyes with four setae anteriorly. Palps dilated at the extremities, with 10 setae throughout their length and four setae at the distal extremities. Gena with six setae. Postgena with five short setae. Notopleural suture with four setae. Female with tergites 4 to 6 divided into two plates. Sternites 3 to 5 divided. Sternite 6 divided into two subtriangular plates. Sternite 7 subtriangular, with lateral and medial portions with depressions, strongly pigmented and without setae. Male: tergites 4 and 5 with medial zone without setae and less sclerotized.

Redescription. Head. Dorsal view—Eyes with a single lens; anteriorly with four setae. Lateral view—Gena with six setae. Postgena with five short setae. Ventral view—Palps dilated at the extremities, with 10 setae throughout length and four setae at the distal extremities. Theca as wide as long, more than twice as long as labella.

Thorax. Dorsal view—Notopleural suture with four setae. Thoracic spiracle pyriform. Thoracic ctenidium with 10 spines. Ventral view—Oblique suture obtuse-angled. Coxa I as wide as long, with setae throughout its length. Femur I wider than long, with setae throughout its length. Tibia I longer than wide, posterior margin with four rows of setae on apical portion. Basitarsus as long as the following three tarsomeres combined. Coxa II short, triangular, with few setae. Femur II longer than wide, rectangular, with no setae on medial portion. Tibia II longer than wide and posterior margin with three rows of setae on apical portion. Coxa III longer than wide, triangular, with setae throughout its length. Femur III longer than wide, rectangular, without setae on medial portion. Tibia III longer than wide and posterior margin with five rows of setae on apical portion.

Abdomen. Female. Tergites and sternites with numerous setae throughout their length. Distal margins of plates with a row of long setae of uneven length. Dorsal view—Syntergite 1+2 and tergite 3 whole, rectangular. Tergites 4 to 6 divided into plates. Tergite 7 with lateral concavity with 6–7 associated setae. Ventral view—Sternite 1+2 whole, rectangular, with a ctenidium of 45 long, thin and covering only middle third of posterior margin. Sternites 3 to 5 divided, rectangular. Sternite 6 divided, rectangular. Sternite 7 subtriangular, with posterior margin almost straight and lateral and medial portions of plate with depressions. Male. Tergites and sternites with numerous setae throughout their length. Distal margin of plates with row of longer setae of uneven length. Dorsal view—Syntergite 1+2 and tergites 3 and 4 whole, rectangular. Tergites 4 and 5 with medial zone without setae and less sclerotized. Anal plate with setae only on posterior margin. Ventral view—Sternite 1+2 long, rectangular, with ctenidium of 56 spines covering middle third of posterior margin. Sternites 3 and 4 whole, rectangular. Sternite 5 long, with a concavity at medial posterior margin and with a rounded lateral margin. Setae more sclerotized than the others and of different size associated with lateral margin.
