Tullgrenella corrugata Galiano, 1981: 218 , figs 6–7 (holotype, female, BRAZIL, Pará [5°58’36.6”S 53°40’36.5”W], W.J. Moenkhaus leg. (MCZ), not examined; 2 female paratypes from the same locality, one in the Milwaukee Public Museum (not examined) and one female (MACN-Ar 7207), examined).

Diagnosis. Males of Tullgrenella corrugata Galiano, 1981 resemble those of T. morenensis , T. brescoviti , T. guayapae , and T. musica by the oblique tegulum in relation to the distal sickle-shaped cymbium ( Figs 4A , 6A–B , 8C–D , 10C–D , 12C–D , 14C–D , 16C–D ), but can be recognized by the large conductor not forming a cradle-shape ( Fig. 16C ). Females of T. corrugata resemble those of T. brescoviti by the large and spiral copulatory ducts in posterior region, and by the separated spermathecae ( Figs 7A, 7E , 17C–D ), but differ from those in having longer and more curved copulatory ducts in the epigynum, the antero-medial copulatory opening, and the epigynum plate with a longer ventral posterior border ( Figs 7E , 17C–D ).

Projections accompanying the embolus, pars pendula about half of embolus length, large conductor about half of embolus length, cradle-shaped, dorsal and retrolateral to embolus, border slightly retrolateral ( Fig. 16C ).

Female. Described and illustrated by Galiano (1981: 218, figs 6–7).

Material examined. ARGENTINA, Buenos Aires, Sierra de La Ventana [38°08’21.6”S 61°47’38.8”W], XI.1971, M.E. Galiano leg., 1♀ (MACN-Ar 42161); ditto, 01.XI.1974, M.E.

Miranda leg., 1♀ (MACN-Ar 42229). Distribution. Brazil [Pará ( Galiano 1981a)], Argentina (Buenos Aires and Córdoba) ( Figs 50A–B ).

Natural history. Some individuals from Argentina, Buenos Aires, Sierra de La Ventana, were associated with rocks and collected manually in a fragment of mountains and grasslands (Cristina Scioscia, personal communication). Some specimens from Argentina were collected with a beating tray and manual collection, suggesting that this species has differentiation between several stratum types. The species was also recorded in the state of Pará, Brazil, which have physiognomies as Amazonian Forest , Mangroves , or Cerrado in Northern Brazil ( Galiano 1981a). This fragment includes the Chacoan subregion ( Figs 50 A – B ). The variation in altitudinal occurrence of this species is 252–628 m a. s. l. ( Figs 50 A – B ).
