摘要

Four species of palicoid crabs, Neopalicus jukesii (White, 1847) and Rectopalicus ampullatus Castro, 2000 of the family Palicidae, and Crossotonotus spinipes (De Man, 1888) and a new species of Pleurophricus A. Milne-Edwards, 1873 of the family Crossotonotidae, are recorded from the Ogasawara Islands, Japan. Diagnostics for the new species are the protruded bilobed front, six subacute lobate teeth at each lateral margin of the carapace, six rounded lobes at the posterior margin of the carapace, a crested armature of the cheliped carpus, and the strongly depressed ambulatory legs, which readily distinguish it from its two congeners, P. cristatipes A. Milne-Edwards, 1873 known by two males from Australia and the Kai Islands in Indonesia, and P. longirostris (Moosa & Serene, 1981) known by a female from the Sunda Strait, Indonesia.

Milne-Edwards,1873年。记录于日本小gas原群岛。新物种的诊断是突出的双叶前部,在甲壳的每个侧缘有六个亚急性叶状齿,在甲壳的后缘有六个圆形的叶,螯状腕骨的冠状电枢以及强烈下垂的活动腿可以轻易地将其与两个同类动物区分开来,即cristatipes A. Milne-Edwards,1873年,来自澳大利亚和印度尼西亚的Kai群岛的两名男性,以及P. longirostris(Moosa&Serene,1981年),其来自Sun他海峡的女性,印度尼西亚。
