Icius hortensis Wiśniewski & Wesołowska, 2024, sp. nov.

Icius hortensis sp. nov. urn:lsid:zoobank.org:act: 870B27B6-68DB-4551-B7E5-F60604935394 Fig. 36 Diagnosis The male of this species has a palp similar to that in males of Icius insolidus (Wesołowska, 1999) from southern Africa. The two species can easily be distinguished by the shape of the tibial apophysis. As seen in lateral view, it is curved in Icius hortensis sp. nov. and straight in I. insolidus. Moreover, the newly described species has a unique palpal femur with large outgrowth on retrolateral surface in the distal part. Etymology The name is a Latin adjective, referring to a ‘garden’ and alludes to the collecting place of the spider, the Botanical Gardens in Entebbe.
