A new species of bristletails of the genus Petrobiellus (Microcoryphia: Machilidae) from Sakhalin
V.G. Kaplin
Abstract. Petrobiellus sachalinensis sp. nov. from the northwest of Sakhalin Island (Russia) is described and illustrated. It is compared with the three other known species of the genus, P. takunagae Silvestri, 1943 from Honshu Island (Japan), P. curvistylis Uchida, 1954 from Hachijo-jima Island (Japan), and P. kusakini Kaplin, 1980 from Simushir Island (Russia). The new species can be distinguished from the congeners by the colour of body and scales, by distribution of pigment, by colour and shape of paired ocelli, and by structure of compound eyes, maxillary palps, legs, urites, and ovipositor.
