Material examined. China: • 1 ♂ 1 ♀, Inner Mongolia, Hulun Buir, Genhe City, Hanma National Nature Reserve, Abei Forest Farm, 51°48'42"N, 122°38'47"E, elev. 1023 m, 2. 07. 2018, R. B. Wu leg. Diagnosis. Acantholycosa aborigenica is similar to A. irinae Fomichev & Omelko, 2020 (Fomichev and Omelko 2020, figs 1, 2, 7, 8, 13–15, 22–24, 48–49) in having the embolic tip bent anteriorly and median apophysis lacking apical arm (Figs 1 A, B, 2 C – F). The males of A. aborigenica can be distinguished from those of A. irinae by the paleal apophysis with broadened end ventrally (Figs 1 A, 2 C, E) (vs. sharp); median apophysis with triangular basal arm in ventral view (Figs 1 A, 2 C, E) (vs. semi-oval); absence of embolic spine near embolic base (Figs 1 A, 2 C, E) (vs. presence). Females can easily be distinguished from those of A. irinae by the septal base occupying 1 / 4 atrium (Figs 1 C, 2 G) (vs. 1 / 2), and septal stem reaching the apical pocket (Figs 1 C, 2 G) (vs. not reaching the apical pocket). Description. See Marusik et al. (2004). Habitus as shown in Fig. 2 A, B, male palp as in Figs 1 A, B, 2 C – F, epigyne as in Figs 1 C, D, 2 G, H. Distribution. From Central Aimag in Mongolia to the upper reaches of the Kolyma River and south to Inner Mongolia (China). Comment. This species belongs to the A. lignaria - group.
