In both sexes, prodorsal and hysteronotal shields close to each other, almost touching; entire surfaces of prodorsal and hysteronotal shields with numerous large circular lacunae, up to 10 µm in diameter ( Figs. 40 A, 41A). In males, pregenital apodemes fused together forming transverse sclerite shaped as a rectangular bracket ( Fig. 42 A). In female, epigynum fused with inner tips of epimerites IIIa, terminal cleft 3.5–4 time longer than wide at midlevel ( Fig. 41 B)...... A. pipromorphae Atyeo, 1967 - In both sexes, prodorsal and hysteronotal shields clearly distant from each other; surface of prodorsal shield with ornamentation other than large circular lacunae or without ornamentation, hysteronotal shield with large ovate lacunae only in posterior part or only with small lacunae. In males, pregenital apodemes represented by longitudinal plates or bands well separated from each other. In female, epigynum free from epimerites IIIa, terminal cleft 2–3 times longer than wide at midlevel..........2 2. In both sexes, prodorsal shield with angular or dash-like lacunae. In males, anterior half of hysteronotal shield with angular lacunae; adanal suckers dentate, tarsus IV with claw-like apical process, opisthosomal lobes with oblique posterior margin ( Figs. 37 A, B, 39A). In females, lacunae on hysteronotal shield of uniform size across all shield ( Fig. 38 A)............................................................................................ A. cuneiformis Mironov sp. n. - In both sexes, prodorsal shield without ornamentation. In males, anterior half of hysteronotal shield without ornamentation; adanal suckers edentate or with faint radial striae, tarsus IV with bidentate apical process, opisthosomal lobes with truncate posterior margin. In females, anterior half of hysteronotal shield without ornamentation, its posterior half with large ovate lacunae............................................................................................. 3. 3. In both sexes, idiosoma 2.5–2.7 times longer than wide.................. A. intermedius ( Trouessart and Neumann, 1888 ) - Idiosoma longer than wide 1.8–2 times in males and 1.9–2.3 times in females......................................4 4. In male, legs IV with ambulacral disc extending beyond posterior margin of terminal lamellae. In female, legs IV extending slightly beyond the level of lobar apices; head of spermatheca as small inflation at proximal end of primary spermaduct............................................................................. A. candango Hernandes et al. , 2007 - In male, legs IV with ambulacral discs scarcely extending to posterior margin of terminal lamellae. In female, legs IV extending to the level of setae h2 ; head of spermatheca pear-shaped............. A. elaeniae Mironov and González-Acuña, 2009
