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 ( Fig. 62 , Chamberlin 1916)
