Tullgrenella guayapae Galiano, 1970: 327 , figs 10–13 (holotype, male, ARGENTINA, La Rioja, Patquía, Guayapa [30°02’39.0”S 66°52’53.2”W], X.1993, M. Galiano leg. (MACN-Ar 6238, examined); paratype ditto holotype (MACN-Ar 6239), examined); Estol et al. 2020: 362, figs 13–14, 19, 30–31 (description of female).

Diagnosis. Males of Tullgrenella guayapae resemble those of T. morenensis by the tegular process globose, higher than the embolar base, the embolus path exceeding the cymbium apex, and the cradle-shaped conductor ( Figs 8C , 10C ), but differ from those by the inclination of tegulum and central straight-marked depression ( Fig. 10C , see red arrow). Females of T. guayapae resemble those of T. morenensis by the copulatory ducts with two loops and the spermathecae close together but can be recognized by the compressed and larger second loop of the copulatory ducts ( Figs 7B , 11C–D ).

Description. See Estol et al. (2020: 358). We add the following complementary data: Male abdomen: epiandrous region with a pair of conspicuous tufts of spigots, bearing at least clustered long spigots ( Figs 31C–D ). Spinnerets ( Figs 18A–D ) examined only in females: spigots, in general, in reduced number in all spinnerets. ALS with two piriform spigots, a single elongate minor ampullate spigot (mAP) at distal portion ( Fig. 18B ), right behind a large tartipore. PLS with single piriform spigot, one proximal prolateral mAp, and single lateral aciniform spigot ( Figs 18C–D ). Tarsal organ ( Figs 19A–D ) examined in female: tarsal organ ( Figs 19A–D ) on dorsal tarsus of legs dropshape ( Figs 19C–D ).

Natural history. Some individuals were collected with D-Vac, pitfall trap, and sweeping net in grassland in Southern Brazil ( Estol et al. 2020), and some species were found associated with Selaginella sellowii Hieron, 1900 ( Selaginellaceae, Lycopodiophyta ) in Uruguay. One female was found with a mantispid larva attached to its pedicel, which has previously been recorded for another species of this genus ( Hagopián & Laborda 2020). The habitat of this species can be considered shrubs and soil/grasslands. It is more restricted to the Chacoan subregion and one record in the South American Transitional Zone ( Figs 50A–B ). The variation in altitudinal occurrence of this species is 13–2476 m a. s. l. ( Figs 50A–B ).
