Tullgrenella gertschi Galiano, 1981: 217 , figs 4–5 (holotype, female, BRAZIL, São Paulo, São Paulo [23°33’18.8”S 46°38’23.5”W], W.J. Moenkhaus leg. (MCZ), not examined; paratype: 1 female, same data as holotype (MCZ), not examined; female, ditto (MACN-Ar 7206), examined).

Diagnosis. Tullgrenella gertschi is close to T. galianoae Marta , sp. nov. by the females having the copulatory ducts posterior-ventral facing the borders ( Figs 7N , 42C–D vs 41C–D) and copulatory ducts in one lap ( Figs 42C–D v 41C–D ), but T. gertschi can be distinguished from it by the septum in ventral epigynum with two depressions like a window ( Fig. 42C ).

Description. See Galiano (1981).

Material examined. BRAZIL, Rio Grande do Sul, Viamão [30°04’16.8”S 51°05’40.9”W], 05.IV.1994, R. Balestrin leg., 1♀ ( MCTP 4848 ) .

Distribution. Brazil (São Paulo and Rio Grande do Sul) ( Figs 53A–B ).

Natural history. Found only in the Chacoan subregion ( Figs 53A–B ). The variation in occurrence of this species is 85–7750 m a. s. l. ( Figs 53A–B ).
