Figs 3 d–g, 52–54, 93

Meriola mauryi Platnick & Ewing, 1995: 36 , figs 97–101 (male holotype from Buenos Aires, Buenos Aires, Argentina, in MACN, examined).

Diagnosis. Males ( Figs 53–54 ) can be easily recognized by the short, triangular RTA, the ventrally directed embolus, and the basally expanded tegulum. Females ( Fig. 52 ) are similar to M. lineolata comb. nov. by having large, oval S2 flanked by the smaller, CDR and S1 ( Platnick & Ewing 1995: fig. 101), and a small hood, but can be distinguished by the larger and more advanced hood ( Fig. 52h ).

Description. Male and female described by Platnick & Ewing (1995).

Natural history and habitat. Several specimens were collected in pitfalls traps.

Distribution. Known from Distrito Federal and Rio Grande do Sul in Brazil, and Misiones, Santa Fe and Buenos Aires provinces in Argentina ( Fig. 93 ).
