Abstract

A new genus of the family Sparassidae is described from Madagascar: Thunberga gen. nov. It can be distinguished from other genera of the Heteropodinae by its different cheliceral dentition and eye arrangement as well as by its uniquely dotted prosoma. Four species are transferred to the new genus: T. hildebrandti (Järvi, 1912) comb. nov. (from Rhitymna Simon, 1897a), T. malagassa (Strand, 1907) comb. nov. (from Olios Walckenaer, 1837), T. nossibeensis (Strand, 1907) comb. nov. (from Olios), T. septifer (Strand. 1908) comb. nov. (from Olios, elevated to species rank). T. hildebrandti comb. nov. is recognised as junior synonym of T. nossibeensis comb. nov. One species is described for the first time: Thunberga greta spec. nov. (female, Madagascar). The systematic placement within the family and the character "anterior epigynal pocket" are discussed.

摘要

马达加斯加发现了蟹蛛科的一个新属

新属Thunberga。它可通过不同的螯牙齿列、眼的排列以及独特的点状前体与异足蛛亚科的其他属相区分。四个物种被转移到这个新属：希氏Thunberga hildebrandti (Järvi, 1912) 新组合（原属Rhitymna Simon, 1897a）、马拉加Thunberga malagassa (Strand, 1907) 新组合（原属Olios Walckenaer, 1837）、诺西贝Thunberga nossibeensis (Strand, 1907) 新组合（原属Olios）、分叶Thunberga septifer (Strand. 1908) 新组合（原属Olios，提升为种级）。希氏Thunberga hildebrandti新组合被认定为诺西贝Thunberga nossibeensis新组合的次异名。首次描述了一个物种：格雷塔Thunberga greta新种（雌性，马达加斯加）。讨论了该属在蟹蛛科中的系统位置以及“前生殖厣袋”这一特征。
