Tullgrenella nadjae Estol, Marta & Rodrigues, 2020: 357, figs 1–6, 15–16, 20–22, 26–27 (holotype, male, BOLIVIA, La Paz, Huatajata, Titicaca Lakeshore [16º12’S 68º41’W], 8.VIII.1993, A. Brescovit & H. Höfer leg. (MCN 23782), examined); paratype, 1 female, ditto holotype (MCN 56814), examined).

Revised diagnosis. Males of Tullgrenella nadjae Estol, Marta & Rodrigues, 2020 resemble those of T. quadripunctata by the pointed and sickle-shaped cymbium, and those of T. lunata (Mello-Leitão, 1944) by the lanceolate conductor (Figs 21C–D, 23C–D), but differ from both species by the retrolateral tibial apophysis long and sinuous, and from T. lunata (Figs 23C–D vs 25C–D) and by the oblique tegulum in T. nadjae (Fig. 23C). Females of T. nadjae resemble those of T. quadripunctata (Mello-Leitão, 1944) and T. lunata (Mello-Leitão, 1944) by the shape of epigynum, as long as wide, and the antero-medially situated copulatory opening (Figs 7F–G, 22C–D). However, they differ from those of T. quadripunctata and T. lunata by the straight loop of the copulatory ducts, above the spermathecae, distant from each other (Figs 7F vs 7G, 24C–D vs 26C–D).

Description. Male and female described by Estol et al. (2020).

Distribution. Bolivia (La Paz) (Figs 51A–B).

Natural history. Recorded at the limits of the Brazilian subregion and South America Transitional Zone (Figs 51–B). The altitudinal occurrence of this species is 3960 m a. s. l. (Estol et al. 2020) (Figs 51A–B).
