Figure 38 ; Map 8

Type. Holotype male: MEXICO: Veracruz: Municipality of Las Vigas , San Juan del Monte , 2400 m, 15.IV– 17.V.1999, Q. Santiago and J. Márquez (CNAN-T0949), deposited at CNAN .

Etymology. The specific name is a noun in apposition referring to the shape of tegular median process of male pedipalp in ventral view, ‘ punta’, which means ‘ pointed’.

Diagnosis. The males of N. punta differ from N. perote and N. valdezi in having the tegular median process exceeding the length of conductor ( Fig. 38 a). The females differ from N. comaltepec in having the atrium withouth sclerotized tips on posterior margin ( Fig. 38 e), from N. perote and N. popoca in having the atrium strongly procurved, and from N. valdezi in having the atrium occupying less than a quarter of the plate length ( Fig. 38 c).
