Bradymerus triplehorni Grimm , new species

( Figs. 1 – 2 )

Description. Holotype male ( Fig. 1 ). Oblong, ferruginous (probably teneral specimen), length 6.0 mm, width 2.4 mm. Genae not broader than eyes. Frons with deep supraorbital furrows, without supraorbital keels. Last 5 antennomeres forming a club. Pronotum wider than long, length/ width ratio 0.81; disc strongly convex transversely, moderately convex longitudinally, with medial impression, rough and partly confluent punctation, interspersed with sharp, sometimes keeled granules, before base punctures more separate; middle of base with nearly smooth depression; anterior angles acute, protruding; lateral margins with distinct crenulation. Elytra strongly convex transversely; puncture rows without striae, borders of deeply impressed punctures bearing 2 microgranules; all intervals with a row of distinct granules or nodules. Tibiae externally without keels, but densely denticulate or sharply granulate, otherwise coarsely, longitudinally punctured; anterior tibiae without tooth. Aedeagus as in Fig. 2 .

Paratype Female. Slightly larger, length 6.5 mm, width 2.6 mm, and darker, black; otherwise conforming with holotype.

Diagnosis. Bradymerus triplehorni superficially resembles Bradymerus kinabalicus Schawaller ( Schawaller 2006: fig. 45) in the general body characters, especially in the surface character of the pronotum and elytra. In B. kinabalicus , the last three antennomeres form a club, the male protibiae are equipped with a tooth, the pronotum is broader, the elytra are less convex transversely, somewhat flattened dorsally, the tibiae are smooth, and the shape of aedeagus is distinctly different (compare Fig. 2 with Schawaller 2006: fig. 110).

Type Material. Holotype male ( NME) and paratype female ( CRG): West Malaysia, Kelantan, 70 km NW of Gua Musang, Mt. Chamah , 1900 m, Kampong Perias, 17.IV. – 9.V.2014, P. Čechovský lgt.

Etymology. The author takes pleasure in naming this species in honor of Charles A. Triplehorn for his valuable contributions to the knowledge of the family Tenebrionidae .
