Type material. Holotype male of Acanthoscurria insubtilis Simon, 1892 from Bolivia, San Mateo, Garlepp col. (MNHN AR 4784 – 15132, examined) . Lectotype and paralectotype females, here designated, of Crypsidromus bolivianus Simon, 1892, from Bolivia, Espiritu Santo, Garlepp col., MNHN AR 4653 – 15135, examined ).

Remark. The larger syntype female of Crypsidromus bolivianus deposited at MNHN (AR4653, 15135) labelled as “ Crypsidromus vel Eurypelma pull”, Bolivia, agrees with the description of Simon (1892a) and is, herein, designated as lectotype. It has stridulatory setae on retrolateral trochanter (Fig. 189), a diagnostic character of Acanthoscurria, and, therefore, is transferred to Acanthoscurria . Espiritu Santo, the type locality of this species, is close to San Mateo, also in Bolivia, the type locality of Acanthoscurria insubtilis Simon, 1892 in which holotype male was captured by the same collector (G. Garlepp) and published in the same paper (Simon 1892a). The type specimen of A. boliviensis has spermathecae with a narrow base and two receptacles closely positioned, corresponding to the female of A. insubtilis (Fig. 290). Therefore, I consider C. boliviensis and A. insubtilis synonyms. Even though A. boliviensis has page priority over A. insubtilis, as first reviser (ICZN 1999, Article 24.2), I choose A. insubtilis as senior synonym of A. boliviensis as that name was cited more times in the literature (World Spider Catalog 2023). Therefore, I consider Acanthoscurria boliviensis (Simon, 1892) n. comb. a junior synonym of Acanthoscurria insubtilis Simon, 1892 .
