TYPE LOCALITY: India , Nicobar Isis, Trinkat Island . DISTRIBUTION: Islands of Trinkat, Little Nicobar, and Great Nicobar in the Nicobar Archipelago. SYNONYMS: burrescens . COMMENTS: Except for larger body size, morphology closely resembles that of most samples of R. tiomanicus from the Sunda Shelf. Whether burrus is an endemic of the Nicobars or whether samples from the three islands are insular variants of R. tiomanicus needs to be tested by a systematic revision of the R. tiomanicus complex (Musser, 1986; Musser and Califia, 1982 ; Musser and Heaney, 1985).
