Three new species of comb-tailed spiders (Araneae: Hahniidae) from a Mexican oak forest with comments on their natural history and sexual behavior

摘要

Three new hahniid species, Hahnia quadriseta sp. nov., Neoantistea multidentata sp. nov. and N. aspembira sp. nov., are described from a total of 1,131 individuals collected during spider inventories in Veracruz, Mexico. All specimens were collected inside four plots of Quercus forest, from leaf litter using active searching, sifted litter processed with Berlese funnels and pitfall traps. Sexual behavior and the natural history of N. aspembira sp. nov. are analyzed. In addition, the stridulatory organ morphology of both Neoantistea species is described. Stridulatory organs are absent in Hahnia quadriseta sp. nov., although present in other species of this genus.
