Differential diagnosis
Females of
A. porta
sp. nov.
can be differentiated from females of all described species of
Anyphaena
of the
pacifica
and
pectorosa
groups by the lateral borders of the epigynum being long and parallel, simulating a pair of lengthy doors slightly open with the hood as the door upper frame. Copulatory ducts weakly sclerotized, path bent 180° at the hood, making two loops (
Figs 39E–F
,
40E–F
,
41G–H
). Similar epigynum shapes are shared with
A. salgueiroi
sp. nov.
and
A. ibarrai
sp. nov.
, but differ, respectively, from
A. porta
sp. nov.
by the almost closed atrium borders (
Fig. 42E
) and the copulatory ducts being heavily sclerotized (
Fig. 43F
). Males have a broad ventral tegular projection with the prolateral edge enlarged, a retrolateral rectangular transparent edge, and two small apical apophyses (
Figs 40A
,
41A
). Distal edge of median apophysis bifurcated, ventral extension the largest and hook-shaped in ventral view (
Figs 40A
,
41A
), dorsal extension translucent and hook-shaped in retrolateral view (
Figs 40D
,
41D
). RTA anterior branch acute, RTA posterior branch tip C-shaped (
Figs 40B–D
,
41B–D
). Coxae II to IV with broad and flat ventral tubercles (
Fig. 41E–F
). Similar broad ventral tegular projections are found in
A. pectorosa
(
Platnick 1974
: figs 51, 55, 59;
Dondale & Redner 1982
: fig. 327),
A. bermudensis
Sierwald, 1988
(
Sierwald 1988
: fig. 1) and
A. zorynae
Durán-Barrón, Pérez & Brescovit, 2016
(
Durán-Barrón
et al.
2016
: figs 5–6, 9), these last two species with coxae unarmed and with small tubercles, respectively.

Etymology
The species epithet refers to the Spanish words ‘
portón
’ or ‘
puerta
’, referring to the door-shaped epigynum atrium, a feature diagnostic of this species.

Distribution
This species is found in oak and tropical wet forest fragments around Pico de Orizaba Volcano National Park (

Natural history
Most specimens were collected over vegetation by direct searching or with a beating tray. This species is present year-round.
