Arctosa denticulata Jiménez & Dondale, 1984: 115 , figs 1–6. Male holotype from near Aguacachil Cave, Taxco, Guerrero, Mexico, 5 June 1981, M. Ramirez leg. (see remarks). Female paratype, same locality of holotype. Examined by photography.

Remarks. This species is the only Arctosa collected inside a cave. It could be an accidental occurrence since the description made by the authors does not indicate any morphological adaptation for subterranean environments. Regarding the depository of holotype, after consulting Dra. Jiménez, she reported that may be deposited in the UNAM. However, the current curator Dr. E. González-Santillan provided information and pictures of paratypes, from same locality and date, but none of them corresponds to the holotype. Therefore, here we conclude the holotype is lost.

Emended diagnosis. The structure referred as a stout spur and a small tooth in the median apophysis by Jiménez & Dondale (1984: fig. 3) is what we call here as posterior arm (Pa), and the small tooth, the retrolateral arm (Ra).Another small tooth on the terminal apophysis, used diagnostically too, is recognized here as the minute palea protuberance. This protuberance is also present in Arctosa jibarosa sp. nov., Arctosa costenola sp. nov. and Arctosa tenebrosa .

Females can be distinguished by the largest and sinuous stalk of spermatheca ( Jimenez & Dondale 1984: fig. 2). Description. Detailed description in Jiménez & Dondale (1984: 115‒116). Distribution. Mexico (Aguacachil Cave, Guerrero State, Fig. 65 )
