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 a).
