Abstract

ABSTRACT The identities of the deep-water brachyuran crabs Carcinoplax abyssicola (Miers, 1885), C. longipes (Wood-Mason, 1891), and C. specularis Rathbun, 1914 (family Goneplacidae MacLeay, 1838) are clarified on the basis of the examination of types and of an extensive series of specimens from the Indo-West Pacific region, including colour photographs of fresh specimens. Two species described from the Philippines, C. verdensis Rathbun, 1914 and C. polita Guinot, 1989, and previously synonymised under C. specularis, are shown to be distinct species. Two new species, C. adelphia n. sp. and C. jugum n. sp., are described from Vanuatu and the Philippines, respectively. Carcinoplax adelphia n. sp. differs from the closely allied C. specularis by having a male first gonopod (G1) that is relatively more elongated, particularly the distinctly more slender distal half, than the G1 of C. specularis. Carcinoplax jugum n. sp. is characterized by a suite of characters that includes an epistome with strongly concave lateral margins, a carapace having distinctly swollen gastric and cardiac regions, and a G1 with a subconical distal part. The taxonomies of these seven species, as well as that of the allied C. fasciata Ng & Kumar, 2016 from southwestern India, are revised. A revised, updated key to the 25 known species of Carcinoplax H. Milne Edwards, 1852 is also provided.

对Carcinoplax深海珊瑚（Miers，1885）和Carcinoplex H.Milne Edwards的七个相关物种的修订，1852年，对两个新种的描述和该属的最新关键字（甲壳纲、十足目、Brachyuna、Goneplacidae）

摘要:根据对印度-西太平洋地区大量标本的类型和检验，包括新鲜标本的彩色照片，阐明了深水短爪蟹Carcinoplax abyssicola (Miers, 1885)、C. longipes (Wood-Mason, 1891)和C. specularis Rathbun (MacLeay Goneplacidae, 1838)的身份。两种描述自菲律宾的C. verdensis Rathbun(1914)和C. polita Guinot(1989)，以前与C. specularis同义，证明是不同的种。在瓦努阿图和菲律宾分别报道了两新种:C. philadelphia n. sp和C. jugum n. sp。与密切相关的镜锥虫不同的是，它的雄性第一性腺(G1)比镜锥虫的G1更细长，尤其是明显更细长的远端。jugum n. sp.的特点是具有一系列特征，包括具有强烈凹侧缘的上位体，具有明显肿胀的胃和心脏区域的甲壳，以及具有亚圆锥形远端部分的G1。本文对这7个物种的分类进行了修订，并对来自印度西南部的C. fasciata Ng & Kumar的分类进行了修订。一个修订，更新的关键，25种已知的致癌菌H.米尔恩爱德华兹，1852年也提供。
