Abstract: Mem Inst Oswaldo Cruz, Rio de Janeiro, Vol. 94(6): 829-836, Nov./Dec. 1999 Quantitative Morphological Evidence for Incipient Species within Lutzomyia quinquefer (Diptera: Psychodidae) JP Dujardin, F Le Pont, E Martinez Code Number:OC99238 Morphological variation among geographic populations of the New World sand fly Lutzomyia quinquefer (Diptera, Phlebotominae) was analyzed and patterns detected that are probably associated with species emergence. This was achieved by examining the relationships of size and shape components of morphological attributes, and their correlation with geographic parameters. Quantitative and qualitative morphological characters are described, showing in both sexes differences among local populations from four Departments of Bolivia. Four arguments are then developed to reject the hypothesis of environment as the unique source of morphological variation: (1) the persistence of differences after removing the allometric consequences of size variation, (2) the association of local metric properties with meristic and qualitative attributes, rather than with altitude, (3) the positive and significant correlation between metric and geographic distances, and (4) the absence of a significant correlation between altitude and general-size of the insects.
