Tullgrenella guayapae Galiano, 1970: 327 View in CoL , 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 View FIGURE 8 , 10C View FIGURE 10 ), but differ from those by the inclination of tegulum and central straight-marked depression ( Fig. 10C View FIGURE 10 , 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 View FIGURE 7 , 11C–D View FIGURE 11 ).

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 View FIGURE 31 ). Spinnerets ( Figs 18A–D View FIGURE 18 ) 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 View FIGURE 18 ), right behind a large tartipore. PLS with single piriform spigot, one proximal prolateral mAp, and single lateral aciniform spigot ( Figs 18C–D View FIGURE 18 ). Tarsal organ ( Figs 19A–D View FIGURE 19 ) examined in female: tarsal organ ( Figs 19A–D View FIGURE 19 ) on dorsal tarsus of legs dropshape ( Figs 19C–D View FIGURE 19 ).

Distribution. Brazil ( Rio Grande do Sul), Uruguay (Maldonado, Rivera, Río Negro and Canelones) and Argentina (Jujuy, La Rioja, and Río Negro) ( Figs 50A–B View FIGURE 50 ).

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 View FIGURE 50 ). The variation in altitudinal occurrence of this species is 13–2476 m a. s. l. ( Figs 50A–B View FIGURE 50 ).
