Redescription of Platygyndes Roewer 1943, a false Gonyleptidae, (Arachnida, Opiliones, Cosmetidae)

Abstract

Praelibitia Roewer, 1956 and its type species, Praelibitia titicaca Roewer, 1956, are respectively syn-onymized with Platygyndes Roewer, 1943 and its type species Platygyndes titicaca Roewer, 1943, and furthermore the genus is transferred from the Gonyleptidae to the Cosmetidae. On the basis of domed and unarmed ocularium, increased number of granules on scutal areas, unarmed dorsal scutum and general body shape, Platygyndes seems to be closely related to Moselabius Roewer, 1956 and Caracarana Roewer, 1956. External morphological characters that are useful to revealing relationships among cosmetid genera are discussed. © P. Pinto-Da-Rocha, M.R. Hara.
