Abstract

The type of the poorly known pilumnid crab, Speocarcinus celebensis Tesch, 1918, is redescribed and figured. As Speocarcinus is now known to be a wholly American pseudorhombilid, the generic placement of this Tesch species has been in doubt. Ng (1987) provisionally assigned it to Viaderiana Ward, 1942, but Števčić (2011) decided to place it in a new monotypic genus, Bossacarcinus. The type is a poorly preserved subadult female, and not a male as originally reported. Bossacarcinus celebensis is likely to be a pilumnine, not a rhizopine, and is compared with allied genera like Viaderiana, Ser Rathbun, 1931, Heteropilumnus De Man, 1895, and Xestopilumnus Ng & Dai, 1996.

论苏拉威西岛的 Speocarcinus celebensis Tesch, 1918（十足目，腕足动物，Pilumnidae）的特征

对鲜为人知的梭子蟹 Speocarcinus celebensis Tesch, 1918 的模式进行了重新描述和图解。由于 Speocarcinus 现在被认为是一种完全属于美洲的假虹彩蝶类，因此该 Tesch 种的属种定位一直存在疑问。Ng（1987 年）暂时将其归入 Viaderiana Ward，1942 年，但 Števčić （2011 年）决定将其归入一个新的单型属 Bossacarcinus。模式标本是一只保存较差的亚成体雌性，而非最初报告的雄性。Bossacarcinus celebensis 很可能是一种柱栖类，而非根栖类，并与 Viaderiana、Ser Rathbun, 1931、Heteropilumnus De Man, 1895 以及 Xestopilumnus Ng & Dai, 1996 等盟属进行了比较。
