Remarks.
The male and female description by
Chamberlin (1916)
presented detailed information on morphology for both sexes.
Holotype
photos confronted with drawings of both epigynum and pedipalp (
Chamberlin 1916: 286
, pl. 24, figs 2–3) suggest transferring to
Hogna
. The male pedipalp has a rounded palea and a sickle shaped terminal apophysis (
Fig. 50b
), which is diagnostic for the majority of
Hogna
species
(
Dondale & Redner 1990
). The epigynum presents an inverted T-shaped pattern and a smooth atrium (
Fig. 51c
). Different from
Trochosa
,
Hogna
median septum is longer than wide, the transversal septum is narrow and about half the length of the median septum (
Dondale & Redner 1990
). Additionally,
H. andina
hoods are parallel (
Fig. 51c
), different from
Trochosa
or
Varacosa
Chamberlin & Ivie, 1942
species
, which have curved hoods. The two parallel bands inside the longitudinal median band are absent in both sexes (
Fig. 51b
), which also excludes placing this species in
Trochosa
. The hoods in
Birabenia
Mello-Leitão, 1941
, also called anterior pockets (
Piacentini & Laborda 2013
) are deep, as opposed to the shallow ones in
Hogna
females. Likewise, the long legs and thick body (
Fig. 51a, d
) are diagnostic of
Hogna
Dondale & Redner 1990
), along with the three, instead of four retromarginal teeth of
Birabenia
. Finally, this species should not be kept in
Arctosa
because the males do not have the reduced palea or TA in different degrees of sclerotization (
Dondale & Redner 1983a
), and females possess the inverted T-shape of the epigynal plate, which is triangular to trapezoidal in
Arctosa
(
Dondale & Redner 1983a
)
. The synapomorphies of
Hogna
used to remove species from this genus and be transferred to
Tigrosa
are summarized in
Brady (2012:182)
.
Diagnosis:
Males of
Hogna andina
can be recognized by the curved cymbium (
Fig. 50b
) and short ventral projection of median apophysis (
Fig. 50c
). Females can be recognized by the dilated and rounded head of spermatheca (
Fig. 51c
).
Distribution.
Known from four localities
Cuzco
,
Peru
including the
type
locality (
