Description. Body length 0.76–0.86 mm, width 0.60–0.69 mm, ovoid, relatively convex in lateral view (1.5 times as long as thick). Color shiny black, with silvery luster. Legs and antennae brown, antenno- meres 2 and 3 paler, 2 nearly whitish. Vertex smooth, with small, sparse, sharply impressed punctures, bearing short setae. Supraantennal sulcus present. Antennal club with 3 antennomeres. Pronotum with punctures as small and sparse as on vertex. Posterolateral callosity of pronotum nearly as large as anterolateral. Elytron ( Fig. 13 ) convex in lateral view [length (from apex to connection with pronotum) nearly equal to height], with punctures smaller and sparser than those on pronotum. Proportions of protarsomeres in male and female (starting with first) 4:2:3:8; mesotarsomeres 4:2:3:8; metatarsomeres 11:2:3:9. Median lobe of aedeagus simple. In ventral view, apex subtriangular, without acute denticle, surface convex. In lateral view, evenly curved throughout, abruptly curved near base; basally narrower than medially; apex nearly straight ventrally. In dorsal view, opening ovoid and relatively wide.

Remarks. Kiskeya micheliorum can be easily separated from the Dominican Republic species K. baorucae Konstantinov and Chamorro-Lacayo, 2006 and K. neibae Konstantinov and Chamorro-Lacayo, 2006 based on the smaller body, and the aedeagus without apical denticle (the aedeagus of both Dominican Republic species has a well-developed denticle). Kiskeya micheliorum differs from K. elyunque by having antennomeres 2 and 3 paler than antennomeres 4 and 5 (in K. elyunque antennomeres 2 and 3 are about as dark as the remaining antennomeres). Kiskeya micheliorum may be separated from other Puerto Rican species with the help of the key at the end of this paper.

Habitat. Kiskeya micheliorum was collected along an unpaved road off the main road in Maricao at the 9.2-mile mark. Two moss bearing trees are located along this small road.

Distribution. Puerto Rico.

Etymology. This species is named after Mona and Julio Micheli and the rest of Micheli family (Ponce, Puerto Rico) in recognition of their contribution to studies of Puerto Rican nature. The epithet is a noun in the genitive case.
