Three new species of the genus Thinodromus Kraatz, 1857 from Indonesia and the Philippines (Coleoptera: Staphylinidae: Oxytelinae)

Abstract

This paper is based on the specimens deposited in the following collections: cMG — private collection of M. Gildenkov (Smolensk, Russia); DUISB — Daugavpils University Institute of Systematic Biology (Latvia); MHNG — Museum d ́Histoire Naturelle Geneva (Switzerland); NHMW — Naturhistorisches Museum Wien (Austria). In the present study, standard methods were used for the taxonomic research of insects; the preparations were made on an MBS-10 binocular microscope. The genital preparations were processed using 10% KOH and then fixed in euparal. In the descriptions and diagnoses giving the length to width ratio for the head, pronotum, and elytra, the following standard units were used: 7 standard units = 0.1 mm; thus, 1 standard unit constitutes about 0.0143 mm. Photographs were taken with a Canon EOS 5D Mark III camera and a Canon MP-E 65 mm objective using the extended focus technology. The distributional maps were created using MapCreator 2.0 software.
