Schubartesia singularis B. Soares, 1944a: 34, fig. 1 (♂); Kury 2003: 192; Kury et al. 2010: 566; (male holotype, Brazil, Bahia, Os Gerais, Rio Branco Valley, MZSP, examined).

Material examined.

BRAZIL. Bahia: (Os Gerais, Rio Branco Valley), male holotype of Schubartesia singularis (MZSP). Minas Gerais: Januária (Parque Nacional Cavernas do Peruaçu), 1 ♂ & 1 ♀ (MZSP 29075); ditto, 2 ♂ (MZSP 29839).

Description.

Penis (Fig. 15 A–C; MZSP 29075): ventral plate with the sides subparallel, with deep cleft on distal margin (U-cleft in ventral view and V-cleft in dorsal view; its apex convergent), 3 pairs of long helycoidal setae, 2 pairs of ventral distal short setae, 1 pair of median short setae, 4 pairs of spatulate, large setae arranged in an oblique row in lateral view, basal lobe short and projected dorsad. Stylus sigmoid, smooth. Ventral process shaft short and wide, apex flabelliform with slightly serrated distal margin.

Taxonomical note.

Schubartesia singularis and Parapachyloides armatus were both formerly placed in Pachylinae and transferred recently to Gonyleptinae by Kury et al. (2010). In that occasion, they justified the transfer arguing that penial features are typical of those of Gonyleptinae , but they did not formally described or characterized them. Despite the typical " Pachylinae " general aspect (four scutal areas on dorsal scutum, robust pedipalps and conspicuous trochanter armature), the penis morphology, such as the deep cleft on distal margin of the penis ventral plate, indicates that it belongs to a more derivative gonyleptine lineage.
