Type. Holotype male: MEXICO: Chihuahua: Sierra del Nido, Arroyo del Álamo, 29°20′N, 106°50′W, 27.XII.1969, V. Roth (CASENT 9048865), deposited at CAS.
Etymology. The specific name is a noun in apposition referring to the color tone of the holotype ‘clara’ which means ‘ light’.
Diagnosis. The males of this species differ from N. approximata and N. bosencheve in having the tegular median process with one projection (Fig. 19 a) and the RTA with a denticle on ventral projection (Fig. 19 b). The females differ from N. approximata in having the spurs more conspicuous (Fig. 19 c), from N. franckei and N. volcanes in having the primary spermathecae with posterior part wider than anterior part (Fig. 19 d), from N. paricutin in having the spurs directed mesally, from N. saltoensis in having the spurs separated from the posterior margin by their basal width, and from N. creel in having the spurs in lateral position (Fig. 19 c).

Sternum brown with a central yellow band with arrowhead shaped spot. Legs yellow with black spots on coxa and trochanter, three black rings on femur, two on patella, and two on tibia.
