Other material examined. BRAZIL, Rio Grande do Sul, São Francisco de Paula, Potreiro Velho [29°28’50.5”S 50°10’28.0”W], 24.IV.2006, A.A. Lise leg., 1♀ ( MCTP 35720 ) . URUGUAY, Maldonado, Sierra del Carapé [34°31’41.0”S 54°58’09.0”W], 21.X.2019, collected under rock, 1♀ (FCE-Ar 12155) .

Etymology. The name means “very cool” in Portuguese, a comment frequently made by the authors of this species whenever they find new species of jumping spiders. Noun in apposition.

Diagnosis. Tullgrenella legalissima Marta & Hagopián sp. nov. resembles T. serrana , T. aisenbergae Marta sp. nov., and T. sciosciae Marta & Bustamante sp. nov. by the C-shaped initial copulatory ducts ( Figs 7K–N ), but can be distinguished from T. aisenbergae Marta sp. nov. by the sclerotized, posterior-ventral space between copulatory opening and posteriorly-opening coupling pocket ( Figs 7L vs 7M, 35C–D vs 37C–D). It can also be recognized from aforementioned congeners by the ovoid spermathecae ( Figs 7L , 35D ).

Spinnerets: coloration as abdomen’s dorsum ( Figs 35A–B ). Epigynum: copulatory opening posterior-medial into a fillet that widens posteriorly forming pockets near a short pCP ( Figs 7L , 35C–D ). Copulatory ducts arranged in one monoplanar spiral, C-shaped, with one medial-dorsal thinner twist right before reaching the spermathecae ( Figs 7L , 35D ). Spermathecae ovoid, with the base of fertilization ducts placed on the anterior/dorsal surface ( Figs 7L , 35D ).

Distribution. Brazil (Santa Catarina and Rio Grande do Sul) and Uruguay (Cerro Largo and Maldonado) ( Figs 53A–B ).

Natural history. Some individuals were collected under rocks in Uruguay. This suggests that this species inhabits a soil habitat. It is found only in the East of the Chacoan subregion ( Figs 53A–B ). The variation in altitudinal occurrence of this species is 8–908 m a. s. l. ( Figs 53A–B ).
