Tullgrenella selenita Galiano, 1970: 348 , fig. 5–9 (holotype, male, ARGENTINA, Chubut, Lago Futalaufquen [42°48’59.6”S 71°42’58.8”W], II.1969, A. Gosztonyi leg. (MACN-Ar 6249), examined).

Diagnosis. Males of Tullgrenella selenita resemble those of T. peniaflorensis by the tegular membranous process up than embolar base, but can be recognized by the larger borders of conductor and the distal inclination of the proximal retrolateral lobe of tegulum ( Figs 48C–D ). Females of T. selenita resemble those of T. peniaflorensis by the antero-medial copulatory opening facing up, but can recognized by the shorter copulatory ducts in one lap ( Figs 7Q vs 7P, 49C–D vs 47C–D).

Copulatory ducts arranged in monoplanar spirals, with one turn( Figs 7Q , 49C–D ). Spermathecae circular, with the base of fertilization ducts placed on an anterior/dorsal surface. Fertilization ducts extended anteriorly to the sides ( Figs 7Q , 49C–D ).

Material examined. CHILE, Región de Aysén, Cochrane, Puerto Bertrand (47º7’27.96”S 72º 39’42.11”W), 10.IV.2006, R. Briones leg., 1♀ ( FNAG36 1456); South Cochrane (47º7’46.96”S 72º43’52.16”W), 14.IV.2006, R. Briones leg., 1♂ ( FNAG36 1078) .

Distribution. Argentina [Chubut ( Galiano 1970)], Chile (Cochrane) ( Figs 54A–B ).

Natural history. Individuals were collected in the leaf litter in a forest with the presence of Nothofagus dombeyi (Mirb.) Oerst. The variation in altitudinal occurrence of this species is 186–530 m a. s. l. ( Figs 54A–B ).
