Tullgrenella brescoviti Estol, Marta & Rodrigues, 2020: 358 (holotype, male, BOLIVIA, La Paz, Laguna Viscachani [16°31’00.0”S 68°12’00.0”W], 05.VIII.1993, A.D. Brescovit leg. ( MCN 23871 , examined); paratype, 1 female, BOLIVIA, La Paz, Valle del Zongo [16°31’00.0”S 68°12’00.0”W], 05.VIII.1993, H. Höfer leg. ( MCN 24104 ), examined).

Revised diagnosis. Males of T. brescoviti resemble those of T. guayapae Galiano, 1970 (see Galiano 1970: figs 10– 13) and T. morenensis ( Tullgren, 1905) (see Galiano 1970: figs 1–2) by the tegular membranous process globose, and the cymbium pointed and sickle-shaped ( Figs 8C , 10C , 12C ), but differ from T. guayapae by the larger conductor, distal embolus not exceeding the length of the cymbium apex ( Figs 12C–D vs 10C–D), and from T. morenensis by the tegulum oblique and the acute RTA ( Figs 12C–D vs 8C–D). Females of T. brescoviti resemble those of T. didelphis ( Simon, 1886) (see Galiano 1963: fig. 11; Galiano 1970: fig. 58) and T. morenensis (see Galiano 1970: fig. 57) by the long copulatory ducts with the first loop oval, and the presence of posteriorly opening coupling pocket, but differ from both species by the smaller spermathecae, distant from each other ( Estol et al. 2020).

Description. See Estol et al. (2020) ( Figs 12–13 ).

Distribution. Bolivia [La Paz ( Estol et al. 2020)] ( Figs 50A–B ).

Natural history. The species was collected in the Puna grassland ecoregion. Puna is characterized by a biome of montane grasslands and shrublands in the central Andes Mountains of South America ( Estol et al. 2020). This species is recorded in sympatry with T. didelphis ( Simon, 1886) in the Brazilian subregion and South America Transitional Zone ( Figs 50A–B ). The altitudinal occurrence of this species is 3600 m a. s. l. ( Estol et al. 2020) ( Figs 50A–B ).
