Comment: The type material of L. vilis was revised and a lectotype was designated earlier (ASSING 2008). The original description of Lithocharis jacobsoni is based on an unspecified number of syntypes from " Sumatra: Fort de Kock" (CAMERON 1928). Five syntypes, one male and four females, were located in the Cameron collection at the BMNH. The male is evidently teratological: its abdomen did not contain an aedeagus and its sternite VII lacks a comb of palisade setae at the posterior margin. Similar malformations were observed also in another male of L. vilis, in one of L. mateui, and in one of L. sororcula. The examined male, which is designated as the lectotype, is undoubtedly the specimen which Cameron (1928) based his diagnosis and illustration on. Externally, the type material of L. jacobsoni is indistinguishable from L. vilis, which too was found in the type locality of L. jacobsoni. Thus, there is no reasonable doubt that L. jacobsoni is in fact conspecific with L. vilis.
Lithocharis vexans was described from a unique female holotype from "Dago Bandoeng" (CAMERON 1936). In external characters the holotype is identical to L. vilis. Hence the synonymy proposed above.
According to SCHÜLKE & SMETANA (2015), L. vilis has a cosmopolitan distribution. Confirmed records are currently known from the Canary Islands (ASSING 2000), Madeira (ASSING & SCHÜLKE 2006), Sri Lanka (ASSING 2008), China, Laos, Thailand, Malaysia, Singapore, Indonesia (Sulawesi, Java, Sumatra), the Philippines, Micronesia, and Australia (see material examined). In view of the frequent misidentifications all other previous records require revision. The male sexual characters are illustrated in ASSING (2008).
