Tullgrenella yungae Galiano, 1970: 352, figs 19–24, 54, 59–60 (holotype, male, BOLIVIA, Santa Cruz [17°42’23.2”S 63°07’57.1”W], II.1964, Martinez, Apostoli & Birabén leg., (MACN-Ar 6251), examined); Pett, Rubio & Stolar, 2021: 933, figs 9I–J (description of female).

Revised diagnosis. Tullgrenella yungae is close to T. melanica, from which it differs by the projections on the tegulum with an angulate basal portion and triangular distal portion (Figs 4C, 29C vs 27C); the openings of the final portion of the copulatory ducts in the spermathecae are located much further forward than in T. melanica (Figs 7J vs 7I, 30C vs 28C), so that the curvature of the ducts is located in an anterior-superior position of the spermathecae, not bordering them as found in T. melanica (Figs 7J vs 7I, 30C–D vs 28C–D).

Description. See Galiano (1970) for male and Pett et al. (2021) for female.
