Plexippus musicus Mello-Leitão, 1945: 294, fig. 85 (holotype, female, ARGENTINA, Corrientes, Goya [29°08’38.7”S 59°15’52.7”W], M. Birabén leg., (MLP 16835), examined; paratype, female Corrientes, Santiago Alcorta [28°47’10.5”S 58°41’35.3”W], M. Birabén leg., (MLP 16862), examined).
Tullgrenella musica: Galiano, 1970: 339, figs 14–18, 63.
Revised diagnosis. Males of Tullgrenella musica are similar to those of T. morenensis by the embolar projections (pars pendula and conductor) (Figs 4A, 6A–C, 14C–D), but can be distinguished by the dimension of conductor (Figs 4A, 6A, 8C, 14C) and the slender pars pendula (Fig. 14C). Females of T. musica resemble those of T. morenensis by the monoplanar spiral copulatory ducts, the window separated by septum (Fig. 5A), and by the posterior circular spermathecae (Figs 7D vs 7A), but can be distinguished by the enlarged copulatory ducts with a lap in dorsalmedian region (Figs 7D vs 7A, 15D).
Description. See Galiano (1970). We add the following complementary data: palp expanded (Figs 6A–C), bulb with a 90º turn, pars pendula visible (Figs 6A–C), and conductor accompanying embolus when basal haematodocha expanded (Figs 6A–C). Basal haematodocha well-developed when expanded (Figs 6A–C).

Distribution. Brazil (São Paulo, Santa Catarina, and Rio Grande do Sul), Uruguay (Maldonado), and Argentina (Entre Ríos) (Figs 50A–B).
Natural history. Based on specimens collected in Brazil, we can conclude that this species is rarely found in grazed and non-grazed grasslands (Silva & Ott 2017). From collections on cacti in Uruguay, this species can be associated with the shrubs and soil habitat. This species occurs in the Chacoan subregion (Figs 50A–B). The variation in altitudinal occurrence of this species is 7–908 m a. s. l. (Figs 50A–B).
