Abstract

Spiders of the islands on the coast of the state of São Paulo, Brazil are poorly known. Herein, we redescribe and discuss the taxonomic position of Psalistops crassimanus Mello-Leitão, 1923, described from Alcatrazes Island and formerly included in the Barychelidae. This species is, herein, transferred to the genus Stenoterommata Holmberg, 1881, Nemesiidae, and the new combination Stenoterommata crassimana (Mello-Leitão, 1923) n. comb. is established. Stenoterommata crassimana males are diagnosed by the very slender and long apical portion of embolus having a strong curvature close to its apex. The females have the spermathecae with single elongate lobe bearing two receptacles. This species is probably endemic to the Alcatrazes Archipelago and Queimada Grande and Queimada Pequena Islands, on the coast of the state of São Paulo, Brazil.

摘要

巴西圣保罗州海岸岛屿上的蜘蛛鲜为人知。在此，我们重新描述并讨论了1923年由阿尔卡特拉兹岛描述的厚掌蛛属（Psalistops）粗掌蛛（Psalistops crassimanus Mello-Leitão）的分类地位，该物种曾被归入重螯蛛科（Barychelidae）。在此，该物种被转移到1881年建立的狭管蛛属（Stenoterommata Holmberg），栉足蛛科（Nemesiidae），并建立新组合狭管蛛粗掌蛛（Stenoterommata crassimana (Mello-Leitão, 1923) n. comb.）。狭管蛛粗掌蛛雄性的触肢器顶突非常细长，在靠近顶端处有强烈弯曲，以此作为诊断特征。雌性的受精囊有单个细长叶，带有两个受精管。该物种可能是巴西圣保罗州海岸阿尔卡特拉兹群岛、大凯马达岛和小凯马达岛的特有物种。
