Differential diagnosis

The epigynal plate in A. urieli sp. nov. is broad, more than two thirds of epigastric furrow length, globular, anteriorly projected and ventrally compressed ( Figs 13C, F View Fig , 14E–F View Fig ), epigynum anterior half with two deep pits ( Figs 14E View Fig (arrow), F, 15G (arrow), H). Similar epigyna are found in A. triangularis sp. nov., but differ from those in A.urieli sp. nov. by their anterior projection being ventrally distended, the shape of the anterior pits, and the path of the copulatory ducts extremely short ( Figs 14A–B View Fig , 15G– H View Fig ). Males of A. urieli sp. nov. are differentiated from those of related species by their ventral tegular projection base being bifurcated with a process shaped like a bird head ( Figs 14A View Fig , 15A View Fig (arrows)), and from A. triangularis sp. nov. by the smaller basal projection of the cymbium ( Figs 14C–D View Fig , 15D View Fig (arrows)), the ventral tegular projection of the retrolateral margin with a transparent cuticular edge, the narrower RTA posterior branch ( Figs 14A, C–F View Fig , 15A, C–F View Fig ), and the smaller coxa II tubercle ( Fig. 15E–F View Fig ).

Etymology

The species epithet is dedicated to Uriel Garcilazo-Cruz, Mexican arachnologist, and former member of the second author’s lab.
