Abstract

The taxonomy of the Sundathelphusa philippina (von Martens, 1868) species group (Brachyura; Gecarcinucidae) from the Philippines is revised, and two new species are described. Sundathelphusa philippina sensu stricto is here restricted to the Bicol Peninsula of southern Luzon, and to the islands of Samar and Leyte. It is one of the largest freshwater crabs in the archipelago, reaching carapace widths of more than 53 mm. Sundathelphusa cebu sp. nov. from Cebu Island is superficially similar to S. philippina in morphology but can be separated by a suite of carapace characters. Sundathelphusa quirino sp. nov. from northern Luzon is the most distinct of the three taxa, with a distinctly more swollen carapace, relatively wider male pleon and a straighter male first gonopod. Sundathelphusa spelaeophila Stasolla, Abbarchi Innocenti, 2015, is also shown to be a junior synonym of S. philippina sensu stricto.

摘要

对来自菲律宾的菲律宾孙氏溪蟹（von Martens，1868年）物种组（短尾派；地蟹科）的分类进行了修订，并描述了两个新物种。狭义的菲律宾孙氏溪蟹在此仅限于吕宋岛南部的比科尔半岛以及萨马岛和莱特岛。它是该群岛最大的淡水蟹之一，头胸甲宽度超过53毫米。来自宿务岛的新物种宿务孙氏溪蟹在形态上与菲律宾孙氏溪蟹表面相似，但可通过一系列头胸甲特征加以区分。来自吕宋岛北部的新物种基里诺孙氏溪蟹是这三个分类单元中最独特的，其头胸甲明显更肿胀，雄性腹节相对更宽，雄性第一触角更直。2015年的洞穴孙氏溪蟹（Stasolla, Abbarchi Innocenti）也被证明是狭义菲律宾孙氏溪蟹的次异名。
