Penestomus prendinii

Only females of Penestomus prendinii are known to science.^[2] The carapace is brown with somewhat rounded lateral margins, covered by fine black setae with broad white setae concentrated posterior to the fovea. The sternum is dusky pale yellow. The chelicerae are brown with five promarginal teeth and two retromarginal teeth, bearing fine black setae only. The legs are dusky brown basally, with anterior legs orange distally and posterior legs yellow distally. The opisthosoma is dark gray dorsally with a pair of broad light dorsolateral patches, covered with a mixture of fine black and broad white setae.^[3]

The species is listed as Data Deficient by the IUCN due to taxonomic reasons, as males remain unknown and the full species range requires further study.^[2]
