Description

Tarsostenus are oblong beetles 3.5–8.0 mm long and 1.0–2.0 mm wide. They can be recognised by a distinctly oblong pronotum with glabrous streaks on the disc and without lateral tubercles, the elytral disc with 10 rows of punctations, and the unguis lacking a denticle.[3]

Several species within the genus have a transverse white band halfway along the elytra.[4]

Ecology

Based on those species whose ecology is known, Tarsostenus are predators on wood-boring beetles.

For example, T. univittatus preys on bostrichids (Lyctus, Sinoxylon, Xylobiops and Trogoxylon[5]) and anobiines.[6] It has been found in borer-infested lumber and wooden furniture from a range of different trees: ash, hickory, persimmon, white oak, Vahellia tortilis (=Acacia tortilis) Hayne raddiana, pecan, Cercis siliquastrum, Corymbia maculata (=Eucalyptus maculata), Ficus retusa, Schinus terebinthifolius and Triplochiton sclerodendron.[5]

Tarsostenus hilaris has been collected from Eucalyptus "laden with various species of cerambycids".[4]

The holotype of T. kanak was collected by beating unspecified vegetation in a rainforest.[4]
