Material examined.

BRAZIL. Locality not specified further, 3 males & 1 female syntypes (NHM 1863.41). Rio de Janeiro: Niterói, female holotype of Xundarava holacantha   (MNRJ 1469); ditto, male holotype of Weyhia absconsa   (MNRJ 1483).

Diagnosis.

Mischonyx scaber   resembles Mischonyx cuspidatus   and Mischonyx poeta   because of armature of the male femur IV: presence of a dorsobasal apophysis relatively short and curved; one retrolateral apophysis on distal third; and a row of high, acuminated tubercles increasing in size from the base to distal third. Mischonyx scaber   can be distinguished from Mischonyx cuspidatus   by the presence of a short gap between the retrolateral row and the retrolateral apophysis on femur IV (the retrolateral row is continuous to the retrolateral apophysis on femur IV in Mischonyx cuspidatus   ). Mischonyx scaber   can be distinguished from Mischonyx poeta   by the absence of enlarged tubercles (present in Mischonyx poeta   ) on the posterior part of the lateral margin of the dorsal scutum.

Taxonomical note.

Mischonyx scaber   was described from Brazil, however, many authors, including Kury (2003), cited other countries as its type locality. It is clearly written “Brazil” on the label of the Gonyleptes scaber   holotype. The only other known specimens of this species are the types of Xundarava holacantha   and Weyhia absconsa   (both in poor condition). The precise distribution records are Rio de Janeiro (Ilha do Governador) and Niterói.
