Diagnosis. Males ( Figs 77View FIGURE 77, 78View FIGURE 78, 79View FIGURE 79 b–e) resemble those of M. lineolata  comb. nov. and M. puyehue  by the very short embolus, partially concealed by the distal part of the bulb, but differ from both by the larger, triangular RTA that is located distally. Females ( Fig. 76View FIGURE 76, 79aView FIGURE 79) also resemble to those of M. puyehue  by the twisted copulatory ducts and closely spaced posterior epigynal ridges, but the ridges are diverging in M. setosa  (parallel in M. puyehue  ), the spermathecae are larger in M. setosa  comb. nov., and the epigyne lacks the elevated median hood.

Notes. We identify the specimen of C. setosa  examined as the type, because its morphology is compatible with the description, and also by the label’s information with Simon’s calligraphy ( Fig. 78eView FIGURE 78), indicating that was collected by “Gou” (Gounelle) in Caraça, a locality in Minas Gerais where Gounelle collected (see Vasconcelos & Melo-Júnior 2001). The specific epithet “hirsuta”, as written on the label, is very similar in meaning to “setosa”, referring to the hairy appearance of this species.

Description. See Platnick & Ewing (1995) for male and female descriptions (under Meriola hyltonae  ).

Natural history and habitat. The specimens were collected in flooded grasslands, under rocks or at grassland at the edge of Baccharis  sp. vegetation (“chilcal”). Some specimens were found in marshes and others in forests, beating shrubs. A few specimens were collected in bird nests of Anumbius annumbi  (“leñatero”) and of Caracara plancus  (“carancho”).

Distribution. Known from southern Brazil, Uruguay and Argentina ( Fig. 94aView FIGURE 94).
