Abstract

A new species of the genus Lasconotus Erichson, 1845 from Ishigaki-jima Island, Southwest Japan, is described. Lasconotus akitai sp. nov. is compared with the three previously known species of Lasconotus in Japan: L. niponius (Lewis, 1879), L. okadai Aoki, 2011, and L. sculpturatus (Sharp, 1885). The new species is characterized by small body size, large eyes, antennal segments III and IV same in size, four sharp ridges on pronotum, and bubble-shaped sculpture on ventral side of body. A key to the four Japanese Lasconotus-species is also given.
