Bálint, Zs. ; Benyamini, D.: Taxonomic notes, faunistics and species descriptions of the austral South American polyommatine lycaenid genus Pseudolucia (Lepidoptera: Lycaenidae): the chilensis and collina species-groups

tain externally collina-like taxa not monophyletic because of what appeared to be tremendous morphological heterogeneity. However, extensive new material (cf. Table 1.) has revealed the intermedial character states allowing a view that this diverse morphology is indeed homologous at base and that the externally collina-like taxa do form a monophyletic group. This group, herein called the collina speciesgroup, includes the previously constructed benyamini, collina, lyrnessa speciesgroups. Its monophyly is supported by the following shared characters: (1) male genital uncus horseshoe-shaped; (2) male genital aedeagus with very short suprazonal element and (3) female genital ostium membranous with sclerotized edges at the vaginal opening (such that, if the entire ostium is sclerotized slightly, it shows a bifurcate structure in lateral view). This monophyly is also supported by the fact that larvae of all these species are breed or feed on the Portulacaceae genus Montiopsis (subgenus Calandrinia) and the Polygonaceae genus Chorizanthe (BENYAMINI 1995 and Appendix II below). Key to the species of the collina species-group occurring in Chile and Argentina based on hindwing ventral markings 1 Horizontal median marking elements lineal (P. collina, P. Humbert, P. shapiroi, P. tamara and P. vera) 2 - Horizontal median marking elements lorate (P. benyamini, P. dubi, P. oraria, P. scintilla and P. ugartei) 6 2 Median line generally continuous with conspicuous black tornai spot in cell CuA2 (P. collina, P. humbert and P. shapiroi) 3 - Median line interrupted with less prominent tornai spot in cell CuA2 (P. vera and P. tamara) 5 3 Tornai spot in cell CuA2 rounded (Figs 9-12) P. collina - Tornai spot in cell CuA2 lineal or triangular (P. Humbert, and P. shapiroi) 4 4 Tornai spot in cell CuA2 lineal (Figs 13-14) P. shapiroi - Tornai spot in cell CuA2 triangular (Figs 15-16) P. humbert 5 Postbasal spot in cell Sc+Rl three times smaller than postmedian spot in cell - Postbasal spot in cell Sc+Rl two smaller than postmedian spot in cell Sc Rl Sc Rl (Figs 17-20) P. tamara or equal in size (Figs 21-24) P. vera
