Type. Holotype female: COSTA RICA: Cartago: Parque Nacional Volcán Irazú , 3000 m, 17.VIII.1983, Coyle, deposited at AMNH .

Etymology. The specific name is a noun in apposition taken from the type locality.

Diagnosis. Novalena irazu distinguishes from N. laticava in having the spurs separated from lateral margins of atrium by their basal width, from N. simplex in having the anterior margin of atrium without lobes, from N.

shlomitae in having the spurs separated by three times their basal width, and from N. cintalapa , N. tacana , and N. triunfo in having the atrium with posterior margin more or less straight ( Fig. 28 View FIGURE 28 a).

Description. Female (holotype): Carapace dark brown. Chelicerae dark brown, condyles orange. Endites and labium dark brown with white tips. Sternum dark brown with a median reddish spot. Legs dark brown, coxa with orange spots. Three black rings on femur. Opisthosoma dark brown with several orange spots, reddish foliage, and five pairs of lateral black dots. Spinnerets dark brown.
