In this paper we revise the species of Sicarius (Araneae: Sicariidae) from the Brazilian Caatinga, the largest tropical dry forest nucleus in the world. We redescribe, designate a neotype and provide new records for Sicarius tropicus (Mello- Leitão, 1936), the only species previously known from the region, and describe three new species: S. cariri n. sp., S. diadorim n. sp. and S. ornatus n. sp. We report high intraspecific variation in the genitalic morphology of these species, especially in females. We also provide anecdotal observations on natural history and behavior of these species, including diet, mating behavior and clutch size. We include an identification key for Brazilian Caatinga species of Sicarius.
在本文中，我们修订了来自巴西卡廷加的刺客蛛属（蜘蛛目：刺客蛛科）物种，卡廷加是世界上最大的热带干旱森林核心区域。我们重新描述了热带刺客蛛（Sicarius tropicus (Mello-Leitão, 1936)），指定了新模标本，并提供了该物种的新记录，这是该地区之前唯一已知的物种，同时还描述了三个新物种：卡里刺客蛛（S. cariri n. sp.）、迪亚多林刺客蛛（S. diadorim n. sp.）和华丽刺客蛛（S. ornatus n. sp.）。我们报告了这些物种生殖器形态的高度种内变异，尤其是在雌性个体中。我们还提供了关于这些物种自然史和行为的趣闻观察，包括饮食、交配行为和产卵量。我们给出了巴西卡廷加刺客蛛属物种的检索表。
