Differential diagnosis
Katasophistes merida is easily recognized because of the striking rows of large and deep systematic punctures along the elytra and its relatively short and stout maxillary palps.
Description
Body length 2.7–3.4 mm, width 1.7–2.4 mm. Body broadly oval, moderately convex (Fig. 10A, B). General coloration dark brown, slightly paler along margins of pronotum and elytra (Fig. 10 A, B). Each elytron with five rows of large and deep systematic punctures. Apex of fifth abdominal ventrite truncate (Fig. 11C). Aedeagus (Fig. 12D) with basal piece nearly 0.8-times the length of parameres; parameres at widest point, nearly 0.6-times greatest width of median lobe; apex of parameres narrowly round; apex of median lobe with median pointed projection.
Etymology
Noun in apposition. Named after the Venezuelan State of Mérida, where the beetles have been collected.
Distribution
Venezuela (Mérida). Elevation range 1616–1682 m. See Fig. 13.
Biology
This species is associated with seepage and waterfall habitats in the Andes, where it has been collected at several sites in wet rock. See Fig. 14 A–D.
