# Trypeticus

Trypeticus is a genus of beetles belonging to the family Histeridae.

## Taxonomy

In 1984, Marseul described the genus as a division of the Neotropical genus Trypanaeus described by Eschscholtz in 1829. Then he included many Indo-malayan Archipelago species based on differently shaped mesosternum. However his most works were described by stating the genus as a subgenus within Trypanaeus. Then in 1916, Bickhardt gave a solid basis for Trypeticus as separate genus and formed the separate subfamily Trypeticinae. Between 1920 and 1930, the forestry entomologist L.G.E. Kalshoven collected several species of the genus on Java and Sumatra which are currently preserved in The Nationaal Natuurhistorisch Museum at Leiden. In 1999, Slipinski and Mazur removed the subfamily Trypeticinae into the synonymy of Trypanaeinae.

## Distribution

The species are distributed throughout Indo-China, Malayan peninsula, the entire Indo-Malayan Archipelago including the Philippines, New Guinea, Northern Queensland, Taiwan, Southeast China, Korea, and Japan as well as Indian subcontinent, Sri Lanka and Nepal.

## Description

Primarily oligophagous, if not monophagous, the beetles depend on xylophagous prey species. Adults show strong sexual dimorphism. The males show great variations with a more or less thick-set body form. However, females are fairly uniform in body form, so can be detect possible patterns of distribution or patterns of diversification. Adults have a cylindrical body form, peculiar tibiae with very long tarsi. The clypeus is more or less prolonged into a rostrum. The antennal flagellum consists of six segments of more or less subconical form. In the resting position, beetle laid down through deep incisions in the anterior prosternal margin of the antennal flagelli. They also can deflect the head and retract it for the greater part into the prothorax. The posterior margin of the prosternum is transverse or at most slightly emarginate.

## Biology

Adult beetles live in the burrows of bark beetles and other wood-boring insects. They can be collected easily by using flight interception traps.
