Kachinus
''Kachinus'' is an extinct genus of ant-like stone beetle in the family Staphylinidae containing the single species ''Kachinus antennatus''. History and classification The type species, ''K. antennatus'', is known from only the holotype, a single, complete adult, now deposited in the American Museum of Natural History as specimen number "AMNH Bu-113". The amber specimen is from deposits in Kachin State, Tanai Village, northwest of Myitkyina, Myanmar. The holotype was first studied by Stylianos Chatzimanolis of the University of Tennessee, Michael S. Engel, Michael Engel of the University of Kansas, and Alfred F. Newton, Alfred Newton of the Field Museum. Chatzimanolis, Engel and Newton published their 2010 Type (biology), type description for ''K. antennatus'' in the journal ''Cretaceous Research''. The genus name is a masculine derivation of the Kachin State in Northern Myanmar where the amber containing the type specimen was unearthed. The species name ''antennatus'' is La ...

Scydmaeninae
Scydmaeninae are a subfamily of small beetles, commonly called ant-like stone beetles or scydmaenines. These beetles occur worldwide, and the subfamily includes some 4,500 species in about 80 genera. Established as a family, they were reduced in status to a subfamily of Staphylinidae in 2009 Many scydmaenine species have a narrowing between head and thorax and thorax and abdomen, resulting in a passing resemblance to ants that inspires their common name. The largest measure just 3 millimeters long, while some very small species only reach half a millimeter in length. Scydmaenids typically live in leaf litter and rotting logs in forests, preferring moist habitats. A number of types are known to feed on oribatid mites, using "hole scraping" and "cutting" techniques to get through the mite's hard shells. In addition to the two living subfamilies, the prehistoric subfamily Hapsomelinae, known only from fossils, has been placed here. Selected genera *'' Cephennium'' *'' Elacatopho ...
