Diagnosis.

Platygyndes   is a Cosmetidae   having the domed and narrow ocularium, instead of the depressed medially and widened one, which is common in eastern and several Andean species. Moreover, this genus possesses the well-marked scutal grooves I–V; the moderately flattened, not dorsally projected pedipalpal femur; and the moderated, laterally flattened pedipalpal tibia which strongly contrast with the typical type observed in the family (strongly flattened and spoon-shaped). On the basis of unarmed domed ocularium and dorsal scutum, the genus seems to be more closely related with Moselabius   Roewer, 1956 and Caracarana   Roewer, 1956. Moselabius   known only after a female can be distinguished from Platygyndes   by larger and sparser tubercles on the dorsal scutum and a paramedian pair of the enlarged tubercles on free tergites I–III and thickened tibiae IV. Caracarana   differs from Platygyndes   by the incrassate femur IV, the pedipalpal tibia with a ventral projection, the thickened and basally constricted tibia IV, the thickened and curved metatarsus IV and the long tarsal process.
