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 View Fig , 8A, D View Fig ). 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 View Fig , 8E View Fig ).

Etymology

The species epithet is dedicated to Dr Adnan Selimovic, friend of the authors and taxonomy supporter.
