Description. Body length 0.73–0.84 mm, width 0.58–0.69 mm, ovoid, relatively convex in lateral view (1.5 times as long as thick). Color shiny black, with pink luster. Legs and antennae light brown, anten- nomeres 2 and 4 paler, 3 nearly white. Vertex dull, with tiny, sparse, weakly impressed punctures, bearing short setae. Supraantennal sulcus present. Antennal club with 3 antennomeres ( Fig. 17 ). Pronotum with punctures as small and sparse as those on vertex. Posterolateral callosity of pronotum much smaller than anterolateral. Elytron ( Fig. 16 ) convex in lateral view [length (from apex to connec- tion with pronotum) nearly equal to height], with punctures as small and sparse as those on pronotum. Proportions of protarsomeres in both male and (starting with first) 4:2:4:8; mesotarsomeres 3:2:3:8; metatarsomeres 8:2:4:8. Median lobe of aedeagus simple. In ventral view, apex subtriangular, without acute denticle, surface slightly convex. In lateral view, evenly curved throughout, including base; basally slightly narrower than medially; apex nearly straight ventrally. In dorsal view, opening elongate, rela- tively narrower basally than at middle.

Remarks. Kiskeya segarrai can be easily separated from the Dominican Republic species K. baorucae and K. neibae based on the smaller body and the aedeagus without apical denticle (the aedeagus of both Dominican Republic species has a well-developed denticle). It may be separated from Puerto Rican species with the help of the key at the end of the paper.

Habitat. Kiskeya segarrai was collected in the same moss cushions as Borinken toronegro , at Toro Negro, the highest point in Puerto Rico, near the phone towers. Moss bearing trees are located on the side of the road that leads to the towers.

Distribution. Puerto Rico.

Etymology. This species is named after Alex Segarra (University of Puerto Rico, Mayaguez) for his contribution to study of insect diversity in Puerto Rico. The epithet is a noun in the genitive case.
