Description

Species of the ant genus Odontomachus in Japan are revised. Type comparison and detailed morphological analysis show that O. kuroiwae (Matsumura, 1912) is an independent species from O. monticola Emery, 1892 and that the former species is distributed in Okinawa Island and Okinoerabu Island in the Ryukyu Islands. Lectotypes of both species are designated. All three castes of O. kuroiwae and O. monticola are characterized. All castes of O. kuroiwae, and the worker and male of O. monticola, are illustrated with scanning electron micrographs and light micrographs. The queen of O. kuroiwae is described for the first time. Odontomachus kuroiwae and O. monticola are morphologically distinguished and taxonomically discussed. Our morphological analysis suggested that O. monticola consists of a complex of several species. Additional notes on the morphology and distribution of both species in Japan are also given.
