| Abstract: | A leading factor responsible for the evolution of Philoliche rondani mouthparts, as in other long-proboscid Pangoniinae, appears to be an adaptation to the consumption of nectar from difficultly available sources (flowers with elongated floral tube). Adaptations to blood-sucking, inherent only to females, have morphogenetic and behavioral aspects. Philoliche rondani males, as compared to males of Tabanus-like tabanids, have better developed clypeus, labrum, and labium. The long-proboscidity leads to the transformation of labial musculature and complication of the food canal structure. Under suction of nectar, the most distal portion of this canal is formed only by the labrum. Lateral labial folds form a peculiar closing apparatus. Cibarial and pharyngeal pumps of Philoliche rondani are similar to those of other tabanids investigated. |
