Diagnosis. Eyes absent. Gena with two setae, one longer than the other. Palps uniform in width, with six setae throughout their length and three on distal portion. Two additional setae on posterior margin, one longer than the other. Thoracic spiracles rounded. Notopleural suture with two associated setae. Female with tergite 6 divided into two plates. Tergite 7 with six setae throughout its length. In ventral view, sternites 4 to 6 divided into two plates.

Redescription. Head. Dorsal view: eyes absent. Lateral view: gena with two setae. Ventral view: palps uniform in width with six setae throughout their length and three on distal portion. Theca longer than wide and twice as long as labella.

Thorax. Dorsal view: notopleural suture with two setae. Thoracic ctenidium with 10 spines. Thoracic spiracles rounded. Ventral view: sternal plate with few setae throughout its length; oblique suture right-angled. Coxa I as wide as long, with setae throughout its length. Femur I wider than long, rectangular, flat, with setae throughout its length. Tibia I with distal posterior margin extremely curved, posterior margin with four rows of setae in apical portion. Basitarsus as long as the following three tarsomeres combined. Coxa II short and triangular. Femur II longer than wide, with setae only on anterior portion; one seta, larger than the others, located in posterior distal region. Tibia II elliptical, posterior margin region with two rows of setae on median portion. Coxa III as wide as long, with setae on distal portion. Femur III rectangular, with posterior margin almost straight. Tibia III longer than wide, posterior margin with five rows of setae on apical portion.

Abdomen. Female. Tergites and sternites with setae throughout length. Distal margin of the plates with a row of longer setae, almost equal in length. Dorsal view—Syntergite 1+2 whole with setae concentrating on the median portion of the plate. Tergites 3 to 5 whole and rectangular. Tergite 6 divided into two plates. Tergite 7 with rounded anterior margin and straight posterior margin. Ventral view—Sternite 1+2 whole, with ctenidium of 44 spines starting from margin of plate. Sternite 3 with a slit in the middle portion. Sternites 4 to 6 divided. Sternite 7 hexagonal with the median portion of the plate without setae.

Male. Unknown.

Type host. Unknown.

Type locality. Unknown.

Geographic distribution. Unknown.

Type material examined. 1 ♀ [holotype, examined from photos], NHMUK, nº010369545. Bat nº35, no further data, N. C. Rothschild coll.

Remarks. The head was difficult to observe on the slide-mounted specimen, so it was not possible to assess the presence of setae. Theodor (1967) mentioned that the anterior margin of the head has four setae. Sternite 3 shows a small gap, almost imperceptible, probably due to poor preservation of the specimen.
