Species included. Tullgrenella peniaflorensis Galiano, 1970 and T. selenita Galiano, 1970 .

Diagnosis. Males can be recognized by the large, longer tegular membranous process higher than the embolar base (Figs 46C, 48C, see purple arrow), the ventral border inclination of conductor (Figs 4F, 46C–D, 48C–D) and the pointed RTA (Figs 46D, 48D); and females mainly by the posteriorly-opening coupling pocket in a horizontal curly bracket-shape, the shorter copulatory ducts, and the anterior copulatory opening facing upwards (Figs 7P–Q, 47C, 49C).

Distribution. Chile (Coquimbo, Valparaiso and Aysén) and Argentina (Chubut) (Figs 54A–B).

Natural history. Found in the north of the Andean region according to the regionalization by Morrone (2014) (Figs 54A–B). Some individuals were collected in the leaf litter in a forest with the presence of Nothofagus dombeyi (Mirb.) Oerst. The variation in altitudinal occurrence of these species is 128–530 m a. s. l. (Figs 54A–B).
