Type species. Icaleptes malkini Kury & Pérez-González, 2002 , by original designation.

Included species. Icaleptes malkini Kury & Pérez-González, 2002 ; Icaleptes dimorphicus sp. nov.; and Icaleptes armasi sp. nov.

Emended diagnosis. Icaleptes can be differentiated from Zalmopsylla by the male lacking the sulci of the scutum magnum; large coxa IV occupying the middle third of the mesotergum; coxa IV with huge ventral protuberances (except in I. malkini ), located around or very close to the genital operculum; femur IV barely armed, with only a few distal retrolateral pointed tubercles; and the two proximal basitarsomeres of leg III fused and slightly enlarged. In the male genitalia of Icaleptes , the capsula externa is modified into a robust stragulum with two widely, but not entirely, separated apical lobes. This allows visualization of the wide capsula interna with a well-developed parastylar collar in dorsal view. In contrast, Zalmopsylla has the capsula externa modified into a stragulum with a bulbous base, projected into a powerful sclerite with two expanded branches (left and right) running close alongside each other, completely concealing the capsula interna in dorsal view. The ventral plate of the penis in Icaleptes may be entire or differentiated into a basal wide pergula and an apical short and stout rutrum, whereas in Zalmopsylla , the ventral plate has a subapical constriction, is expanded into left and right apical lobes and has a pointed median apex.

Distribution. COLOMBIA, Sierra Nevada de Santa Marta, Departments of Cesar (Sebastian de Rábago) and Magdalena (Santa Marta and Ciénaga).
