Diphya rugosa TULLGREN, 1902:31 , pl. 3, f. 3 (♀). Syntype ♀ examined after photographs provided by A. Tanikawa (for specimen details see TANIKAWA, 1995:106).

Diphya macrophthalma : TANIKAWA, 1995:106, f. 18 (♀, synonymised two species).

Comments. Diphya rugosa was described based on three specimens from Valley of Aysén River belonging cUrrently to Aysén Province, Chile. TANIKAWA (1995) was first to examined the types. BecaUse of some similarities in shape of median plate of epigyne, and presence of mating plug in epigyne of D. macrophthalma hiding fovea, he considered two species as synonyms. Comparisons made in this study, show that the epigyne of D. rugosa and D. macrophthalma (figs 18 and 17 respectively in Tanikawa, 1995) differ in siZe (respectively Figs 32, 30 ). It is clear that the epigyne of the former species is larger and the marginal plates well differ in shape. After maceration of epigyne of D. macrophthalma , it became clear that species is lacking a septum, which is present in D. rugosa . In addition, the type localities of the two species are separated by over 600 km (see Fig. 36 ).
