Diagnosis
Males of Nyetnops madre Villarreal & Martínez sp. nov. resemble those of N. lachonta and N. buruti by having a copulatory bulb (tegulum+embolus), more than 2.2 × as long as palpal tibia but differ from those of N. buruti and N. lachonta by having the tegulum basal section of almost the same width as the distal section across the entire length of the bulb ( Fig. 7A–B View Fig ), instead of a distinctly narrower basal section as in N. buruti and the narrowing in the anterior section of the tegulum apical section in N. lachonta ; additionally, the males of this species have an embolar subapical dorsal and ventral serrated keel unique in the genus. Females are similar to those of N. guarani by having the posterior plate wide and a triangular distal margin of the receptaculum but can be distinguished by the less sharp dorsal margin of the receptaculum ( Fig. 7C–D View Fig ).
Etymology
The specific epithet is a noun in apposition taken from the type locality Madre de Dios.
