Popis: Anyphaena adnani sp. nov. urn:lsid:zoobank.org:act: 44F20A0E-E32D-43DC-B7B2-1AE4AA62AC21 Figs 2A–B, 6–8, 52 Differential diagnosis Males of A. adnani sp. nov. have the RTA anterior and posterior branches similar to those of A. bromelicola Platnick, 1977 (Platnick 1977: figs 5–6), but differ from this species by the sharper point of the RTA anterior branch and the ventral tegular projection tip acute and being less curved (Figs 7A, D, 8A, D). Females of this species are differentiated from those of A. bromelicola (Platnick 1977: figs 7–8) by the flattened hood, shorter midpiece, and wider atrium (Figs 7E, 8E). Etymology The species epithet is dedicated to Dr Adnan Selimovic, friend of the authors and taxonomy supporter.
