Abstract

Pinnotherid crabs are well known as obligate associates of other marine invertebrates, frequently bivalve molluscs. Knowledge of the Australian pinnotherid crab fauna is expanded by description of a new species of Viridotheres Manning, 1996, representing the first record of the genus from Western Australia. The new species of Viridotheres is most similar to V. gracilis (Bürger, 1895) from the Philippines and V. takedai Ahyong, Komai & Watanabe, 2012 from Japan, but is unique in the genus in the elongated maxilliped 3 palp that distinctly overreaches the propodal apex. The identity of the poorly known northern Australian species, Pinnotheres latipes Hombron & Jacquinot, 1846, originally described from the Northern Territory, is resolved by designation of a neotype that places the species in the genus Nepinnotheres Manning, 1993. Nepinnotheres latipescomb. nov. is widespread in northern Australia and commonly hosted by the bivalve mollusc Pinna Linnaeus, 1758. Previous Australian records of Nepinnotheres cardii (Bürger, 1895) and N. edwardsi (De Man, 1888) from Australia are referable to N. latipes. Nepinnotheres latipes is one of only five known pinnotherids having androgynous males. Few pinnotherids are known from males, so estimating the extent of androgyny in Pinnotheridae must await discovery of males of additional species.

摘要

Pinnotherid螃蟹是众所周知的其他海洋无脊椎动物的专性伴生，通常是双壳软体动物。通过描述1996年新的Viridotheres Manning物种，扩大了对澳大利亚pinnotherid螃蟹动物的了解，这是西澳大利亚州属的第一个记录。Viridotheres的新种与菲律宾的V. gracilis（Bürger，1895）和日本的V. takedai Ahyong，Komai＆Watanabe，2012最相似，但在拉长的maxilliped 3纸浆中是独特的，明显超过了足尖。鲜为人知的北澳大利亚物种Pinnotheres latipes的身份最初从北领地描述的Hombron＆Jacquinot，1846年，通过指定将新物种置于Nepinnotheres Manning属（1993年）中的新种来解决。Nepinnothereslatipes进行梳理。十一月 该病在澳大利亚北部很普遍，通常由双壳软体动物Pinna Linnaeus主持，1758年。澳大利亚以前记录的来自澳大利亚的Nepinnotheres cardii（Bürger，1895年）和N. edwardsi（De Man，1888年）都被称为N. latipes。猪笼草是仅有的五个雌雄同体雄性pinnotherids之一。从雄性中知道很少有pinnotherids，因此要估计Pinnotheridae中雌雄同体的程度必须等待发现其他物种的雄性。
