Diversity and Distribution. Ceratus is a moderate sized group consisting of 23 described species. Eleven species are precinctive on the Philippines. Eight species have been taken in Indonesia (Java, Sulawesi, and Sumatra), Malaysia (Bornean and Penninsular) and Papua New Guinea. Two species, Ceratus remotus (Fleutiaux) and Ceratus scotti Fleutiaux are present on Seychelles. Muona (1993) described the extinct, Ceratus woltani from Baltic amber. Two new species have been taken on the Asian mainland, including one described here. Additional undescribed species may be present elsewhere in Southeastern Asia.
