The firefly genus Reductodrilus Pic, 1943 (Coleoptera, Lampyridae) in the Philippines

The genus Reductodrilus Pic, 1943 has hitherto been considered monotypic, comprising a single described species from Borneo. Here, Reductodrilus from the Philippines is revised and three endemic species recognized. Reductodrilus longelytratus Packova & Kundrata, sp. nov . and Reductodrilus maculatus Packova, Vorst & Kundrata, sp. nov . are described. Furthermore, Dodecatoma testaceiceps Pic, 1924 (formerly placed in Rhagophthalmidae) is transferred to Lampyridae as Reductodrilus testaceiceps (Pic, 1924), comb. nov ., and Ototretadrilus philippinus Wittmer, 1941 established as its new junior synonym. In addition, a lectotype is designated for Dodecatoma testaceiceps . This revision improves our understanding of the poorly known Southeast Asian Ototretinae and demonstrates that the diversity of Philippine Ototretinae has been substantially underestimated.
