Rhene amabilis Wiśniewski & Wesołowska, 2024, sp. nov.

Rhene amabilis sp. nov. urn:lsid:zoobank.org:act: 0419FA65-C512-4D9E-8985-995E38640EAF Figs 73–74 Diagnosis The species is distinctive in having a unique form of the genitalia. The male can be distinguished from its congeners by the shape of the embolus, which is wider at the tip than at the base and in ventral view looks as if it was two-tipped (Figs 73C, 74B). The epigyne has spacious chambers in the initial part of the copulatory ducts, with adjacent large accessory glands. A similar internal structure of epigyne can be seen in Rhene konradi Wesołowska, 2009 but its accessory glands are smaller (compare Fig.74F with Wesołowska 2009b: fig. 8). Etymology The specific name is Latin, meaning ‘attractive’, and refers to the pretty body form of this spider.
