Complementary description.

DS Epsilon type 2 (Fig. 3A ). Anterior and lateral margins of DS smooth, posterior margin with some granules. Ocularium low, with median concavity, unarmed (Fig. 3B ). Mesotergum delimited, divided into four areas, granulate; area I divided longitudinally, areas II-IV undivided; AHF: II = I<III = IV (Figs 3B-E ). Posterior margin of DS substraight. Free tergites I-III with granules (Fig. 3E ). Cheliceral hand swollen. Legs increasing in thickness from leg I to leg IV, unarmed, leg I filiform. Fe IV two times DS length (Fig. 3B ). Penis with small LP (height less than width), apex with anterolateral sharp corners. Malleus with two pairs of branched MS-A; one pair of branched MS-B; MS-C absent; MS-D absent (see remarks); MS-E2 large and trifid, MS-E1 absent. Stylus elongated, curved at distal third, surpassing the lamina parva, with dorsal process and dorsal connective tissue (Fig. 3F ).

Remarks.

It seems that MS-D and MS-E1 went unnoticed or ignored in some works of González-Sponga (1981, 1987, 1998). However, Barinas species has these MS, as explained by Ahumada-C. et al. ( 2020). Therefore, we suspect that they are present in B. virginis comb. nov. as well, but only a revision of the male genitalia could settle this issue.
