Tetropiopsis

Tetropiopsis

*Tetropiopsis* [auct., verify] is a small, monotypic genus of spondylidine longhorn beetles native to Japan, where adults are encountered from May through August on dead or dying conifers at elevations ranging from sea level to 1,500 metres. The beetles are dark brown to black and cylindrical in outline, measuring 10–20 mm, and fly predominantly at night. Larvae develop deep within sapwood of Pinaceae hosts over a protracted period of two to four years, making this genus a characteristic element of conifer deadwood communities in eastern Asia.
