Diagnosis. Males are distinguished by their much larger basal conical process of the male palpal tibia ( Fig. 4B, C View FIGURE 4 ); from N. cisnerosi they are distinguished by their PAC longer and prominent, while PAC small and inconspicuous in the latter (Peñaherrera-R. et al. 2023: fig. 5c).

Etymology. The specific epithet is a non-Latin adjective (invariable) derived from the Spanish adjective “canosa”, meaning white hairs referring to the species densely covered with white setae.
