Kiskeya baorucae new species

( Figs. 1–23 )

Description. Body length 1.06–1.10 mm, width 0.86–1.02 mm. Color black with light greenish luster. Femur dark brown, rest of legs and antenna dark yellow. Vertex smooth, without punctures or wrinkles. Supraantennal sulcus absent. Pronotum with tiny, sparse, sharp punctures. Elytron convex in lateral view [length (from apex to connection with pronotum) nearly equal to height], with tiny, sparse, barely visible punctures. Proportions of protarsomeres of female (starting with first) 9:4:6:11; mesotarsomeres 7:3:7:11; metatarsomeres 11:3:7:12. In male, proportions as follows: protarsomeres 9:4:5:10; mesotarsomeres 7:3:6:11; metatarsomeres 12:4:7:12. Apical tergite of female sinuous at apex ( Fig. 20 ). Vaginal palpi widely separated anteriorly, with eight long setae posteriorly ( Fig. 19 ). Posterior sclerotization straight medially, laterally curved towards middle, narrowly rounded at apex. Spermatheca ( Fig. 22 ) with receptacle longer and wider than pump. Outer side of receptacle convex, inner side slightly concave. Vertical part of pump much shorter than horizontal. Apex of pump with small denticle. Tignum curved laterally, posterior sclerotization without sharp borders ( Fig. 21 ). Apex of median lobe of aedeagus ogival in shape with well developed, long, and acute denticle ( Fig. 23 ). Apex slightly curved dorsally in lateral view.

Etymology. The specific epithet is a noun in apposition based on the type locality.

Ecology. Unidentified moss samples which contained K. baorucae were collected in the forest from a variety of substrates (rocks, tree stumps, trunks and branches) ( Figs. 25, 26 ) in both 2005 and 2006. Labels on specimens from Carnegie Museum indicate sweeping as a method of collecting.
