For each genus is given the bibliographic reference relative to the original description, its sy - nonyms and the number of total known species. A review of current knowledge about Psela - phinae from the National Park of Amber Mountain (Northern Madagascar) shows that for this area are at present known 16 genera (14 endemic to Madagascar and one of Amber Mountain) and 23 species, all malgasy endemic, 19 of which are known only for the Amber Mountain area. During faunistic researchs carried out in this district, from 18 to 31 March 2011, were collected seven genera ( Faronitopsis , Trissemus , Leichotrella , Ctnenistes , Acylotyrus , Ei - chiella and Rhynchoclaviger ) reported for the first time for Amber Mountain area. The rese - arch confirms the high biodiversity of malgasy Pselaphid fauna and some of its characteristics as the coexistence in the same area of more congeners species, sometimes very similar to each other, contrary to what occurs in temperate regions. Besides the classic environment of the soil, in Madagascar there are many species that live on herbaceous vegetation or on the bran - ches of trees, in particular those belonging to the tribe of Brachyglutini and Ctenistini.
