Abstract:

Background: Ariston O. P.-Cambridge, 1896 and Siratoba Opell, 1979 are two poorly known genera of the spider family Uloboridae, which together comprise six nominal species previously described. This study provides an update of the taxonomic status for both genera and the description of two new species for Ariston. Results: The male of Ariston albicans O. P.-Cambridge, 1896 is described and illustrated for the first time, based on specimens from Chiapas, Mexico; Ariston reticens Gertsch & Davis, 1942 is transferred to Siratoba, and Siratoba sira Opell, 1979 is considered its junior synonym; Ariston spartanus n. sp. is described based on male and female collected in Caicubi, state of Roraima, Brazil; and Ariston aglasices n. sp. is described based on a female collected in Bonampak, Chiapas, Mexico. Conclusions: An emended diagnosis for Ariston and Siratoba and for each previously known species is provided. In total, five species are recognized in Ariston, including two new species, and two species are recognized in Siratoba.
