Megapachylus grandis Roewer, 1913 Fig. 13

Megapachylus grandis Roewer, 1913: 124, fig. 56 (♂); Kury 2003: 131.

Metapachyloides almeidai Soares & Soares, 1946: 317, fig. 2 (♂); Kury 2003: 176; (male holotype; Brazil, Batea, São Paulo, Lane & Soares leg., V.1943; MZSP 883; examined) Syn. n.

Description.

Penis (Fig. 13 A–C; MZSP16837): ventral plate with slightly convergent lateral sides deep U-cleft on distal margin, its apex folded ventrally, 3 distal pairs of large setae, slightly curved at apex, 1 median pair of short setae and, 4 basal pairs of spatulate setae, directed frontwards. Glans with dorsal process. Stylus thin, long, sigmoid, with subapical ventral trichomes. Ventral process shaft folded ventrally, apex flabelliform, with serrate distal margins and long distal tip.

Taxonomical note.

The male of the species described by Soares & Soares shows a moderate development of armature of leg IV but the number and arrangement of tubercles are perfectly coincident with those of Megapachylus grandis . It could be a beta male, although an extensive population study should be conducted to confirm this.
