Etymology
. The specific name is a patronym in honor of Fernando Álvarez Padilla, one of the collectors of the
holotype
, for his contribution to spider taxonomy in
Mexico
.
Diagnosis
.
Novalena alvarezi
differs from
N. intermedia
in having the atrium procurved, from
N. ajusco
and
N. leonensis
in having the spurs separated by their basal width, and from
N. dentata
in having the atrium strongly procurved (
Fig. 16
