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).
