First illustrated description of the male of <i>Diphya macrophthalma</i>, the type species of the genus (Araneae, Tetragnathidae)

Diphya macrophthalma Nicolet, 1849, a type species of the genus and known by only holotype female from Central Chile, is redescribed in details based on recently collected material. The male is described in details and illustrated for the first time. Diphya rugosa Tullgren, 1902 previously considered as junior synonym of D. macrophthalma is revalidated. The known distribution of Diphya species from southern South America is mapped. Comments about status of northernmost populations of D. spinifera Tullgren, 1902 are given.
