Hypoxys subrastratus (Bergroth, 1891) Nunes et al. (2020) : 423 (diagnosis and distribution).

Diagnosis. See Nunes et al. (2020). Characteristic added here: Male genitalia. Dorsal surface of the pygophore with spot restricted to coarse area ( Fig. 11A — Nunes et al. (2020)). Phallus ( Fig. 7B ). Vesica widening ventrally in lateral view. Phallotheca curved. Female genitalia. Valvifers VIII with mediolateral crest well swollen ( Fig. 9C , black arrow). Pars intermedialis slightly swollen medially ( Fig. 6E ). Capsula seminalis with three thick and long projections: two slightly surpassing anterior annular crest and the other almost reaching base of the pars intermedialis ( Fig. 6E ).

Distribution ( Fig. 12 ): BRAZIL: Pará, Maranhão, Goiás, Minas Gerais, São Paulo, Santa Catarina, Rio Grande do Sul; ARGENTINA: Candelaria; BOLIVIA: La Paz; PARAGUAY: Paraguarí.

Comments. This species can be separated by dorsal rim of pygophore with rectangular median notch and inner wall with the larger swollen area between species of H. triangularis group.
