peniaflorensis group

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 ).
