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 ).
