Type species: Diphya macrophthalma Nicolet, 1849 from central Chile , designated by SIMON (1894) . Diagnosis. Diphya is one of the best delimited genera of Tetragnathidae due to eye pattern and spination of legs I and II. ALE as well as posterior eyes are greatly enlarged and at least 2 times larger than AME (vs. all eyes equal in size, or if sizes heterogeneous, lateral eyes are smallest). In addition to large size, the lateral eyes in Diphya are widely spaced. This character (spaced lateral eyes) is known in only a few Tetragnatha , were all eyes are of equal size. Another character that allows Diphya to be separated from other tetragnathids is retrolateral row of stiff sUbdecUmbent setae on legs I and II ( Figs 1, 2, 4, 8 ) forming kind of capturing basket. Males of species occurring in Chile and Argentina can be distinguished from all other Tetragnathidae by having tibial apophysis ( Figs 9, 12, 14 , 16‒18 ).
