Etymology. The specific epithet is a noun in apposition referring to the type locality. Diagnosis. Males of Patrera chucurui n. sp. can be differentiated from those of the remaining species of the genus by their strongly develop, wide, curved ventral tegular process, by a second spine-shaped projection closely related to the embolus, and by the very long retrolateral tibial apohysis ( Fig. 24F ̅G). Females are distinguished from the remaining species by the ellipse-shaped atrium, lateral borders united posteriorly, convulated, long copulatory ducts and by the absence of a hood ( Fig. 24H ̅I).
