Paratypes: 1♀ (IBSP 118217) same data as holotype; 1♀ (FCE-Ar 9066), URUGUAY, Cerro Largo, Paso Centurión, Aduana [32°08’01.9”S 53°43’57.3”W], 13–16.IV.2017, D. Hagopián leg.

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).
