Diagnosis. Eyes with a pair of associated setae located anteriorly. Gena with three setae. Postgena with three short setae. Palps dilated at their extremity, with 4–5 setae throughout their length and three setae at apex. Dorsal region of thorax with three setae: two located anteriorly at the notopleural suture, one located posteriorly on notopleural suture. Female with tergite 6 divided into two plates and sternites 3, 4, 5, and 6 divided into two plates. Male with all tergites and sternites whole.

Redescription. Head. Dorsal view: eyes with a single lens and a pair of setae located anterior to them. Lateral view: gena and postgena with three setae each. Ventral view: palps dilated at their extremity, with 4–5 setae throughout their length and three setae at the apex. Thecae as wide as long, more than twice as long as labella.

Thorax. Dorsal view: notopleural suture with three setae. Thoracic ctenidium with 12–14 spines. Thoracic spiracle pyriform. Ventral view: sternal plate with setae throughout its length; oblique suture right-angled. Coxa I longer than wide, conical, tapered proximally and with setae only in anterior region. Femur I longer than wide, laterally compressed, with setae throughout length and with one or two long setae in postero-distal region. Tibia I wider than long, laterally compressed, elliptical, with setae throughout its length. Posterior margin with four rows of setae in apical portion. Basitarsus of same size as next three tarsomeres. Coxa II longer than wide, with rare setae on distal margin. Femora II and III longer than wide, rectangular and with few setae throughout their length. Tibia II longer than wide, conical, tapering distally, posterior margin with two rows of setae on median portion. Coxa III as wide as long, triangular, with rare setae throughout its length. Tibia III longer than wide, posterior margin with five rows of setae in apical portion.

Abdomen. Female. Tergites and sternites with few setae throughout their length. Distal margin of plates with a row of setae longer than the others and of different lengths. Dorsal view—Syntergite 1+2 and tergites 3 to 5 whole. Tergite 6 divided into two plates. Tergite 7 whole and short with a straight posterior margin and about 15 setae. Ventral view—Sternite 1+2 whole, short, rectangular. Ctenidium dense, with 52 to 57 spines, occupying entire posterior margin of sternite 1+2. Sternites 3 to 6 divided. Sternite 7 short, with rounded lateral margin and straight posterior margin with about 15 setae. Male. Tergites and sternites with few setae throughout their length. Distal margin of plates with a row of setae of different lengths. Dorsal view—Syntergite 1+2 whole and triangular. Tergites 3 to 5 whole, rectangular. Tergite 5 with two setae longer than the others on posterior margin of plate. Tergite 6 short, with six setae longer than the others at posterior margin. Anal plate with microtrichia throughout its length and setae only on posterior margin. Ventral view—Sternite 1+2 whole, with ctenidium of approximately 48 spines across posterior margin. Sternites 3 and 4 whole, rectangular. Sternite 5 with concave median distal margin and rounded lateral margin. Distal margin of sternite 5 with three short setae and more sclerotized than other sternites.

Type host. Thyroptera discifera Lichtenstein & Peters, 1855 .

Type locality. Colombia, Bolivar , Sinú river, Socorré .

Geographic distribution. Colombia (Bolivar) ( Fig. 9 ).

Type material examined. 1 ♀ and 1 ♁ [paratypes], MZUSP, nº46.107, host T. discifera . Colombia. Bolivar , Sinú river, Socorré, March 3, 1949, P. Hershkovitz coll.

Remarks. In their description of the species, Guimar„es & D’Andretta (1956) reported the presence of six tergites. They disregarded the presence of a syntergite owing to the presence of two spiracles associated with the first tergite plate. For this reason, the terminology of the ventral and dorsal plates was modified in the present work.
