Caccothryptus

Caccothryptus is a genus of minute marsh-loving beetles in the subfamily Limnichinae. The genus was formally established (circumscribed) by the entomologist David Sharp in 1902, with C. compactus as the type species. In 2014, the entomologists Carles Hernando and Ignacio Ribera published a major revision of the genus, reorganizing it from seven species into twenty species in five species groups, classified mainly by similarities in genital shape. Discoveries in the following years have brought the total number of species up to thirty-four. Due to the relative lack of studies and material on Asian Limnichidae, more species are likely still to be described. Ranging from 2.5 to 5.5 mm in total length, the beetles have ovoid bodies ranging from black to brown in color. Their range extends across Southeast Asia, alongside portions of East Asia and South Asia. They generally live in water-logged dead wood adjacent to small streams.

==Taxonomy== Caccothryptus is a genus of Limnichinae, a subfamily of the minute marsh-loving beetles (Limnichidae). The Limnichidae are a diverse family of beetle, absent only from alpine and polar regions, as well as most oceanic islands. They are most commonly riparian, living on the shores of rivers, although some are intertidal (living along beaches or coral formations). However, many genera are fully terrestrial, living in forest litter. Little research has been done on most genera, and the larvae and pupae of most are especially poorly documented. Most species are herbivorous.
