Remark

New to Burma and the Comoro Islands. S. crassus is the most widely distributed member of the genus, now known from continental Asia (Assam, Burma, Thailand, Malay peninsula, Vietnam, China) and from the islands of Ceylon, Penang (ROUGEMONT leg., 1990) and Lombok. It is erroneously cited from Celebes ( ROUGEMONT 1996: 716, and consequently in ASSING 2014: 493); these references should read Ceylon.

This is the first record of a member of the genus outside the oriental region; this is not very surprising however, as a number of other oriental Staphylinidae (e. g. Astenus leptocerus (Eppelsheim) , A. maculipennis (Kraatz) , Cephisella brachycera (Kraatz) , C. rufa (Kraatz) , Medon planus (Kraatz) , Lithocharis sororcula (Kraatz) , Phacophallus spp., Philonthus spp.) occur in other islands of the western Indian Ocean (e. g. Mascarene islands, LECOQ 1986). The fact that these are all species that are common and widespread on the Indian subcontinent and Ceylon, rather than endemic representatives of oriental genera or species groups in a different zoogeographic region, suggests that they were introduced by man, probably in vegetable matter imported from south Asia.
