| wing geometry as a tool for studying the lutzomyia longipalpis (diptera: psychodidae) complex. | toro toro (t) and yungas (y) have been described as genetically well differentiated populations of the lutzomyia longipalpis (lutz & neiva, 1912) complex in bolivia. here we use geometric morphometrics to compare samples from these populations and new populations (bolivia and nicaragua), representing distant geographical origins, qualitative morphological variation ("one-spot" or "two-spots" phenotypes), ecologically distinct traits (peridomestic and silvatic populations), and possibly different ... | 2001 | 11784928 |
