Molecular and morphological characterisation of two closely related species belonging to the subgenus paraphlebotomus-, phlebotomijs chabaudi croset, abonnenc & rioux, 1970 and p. Riouxi depaquit, killick-kendrick & leger, 1998 (diptera, psychodidae).
In 1998, the description of Phlebotomus riouxl emphasised the difficulty to differentiate the female from the closely related P. choboudi, a suspected vector of Leishmanio killicki in several foci in Tunisia. In order to be able to distinguish the females of these two species, we started a molecular study based on 37 Algerian and Tunisian specimens. The alignment of the sequences of the cytochrome b of the mitochondrial DNA and their analysis using Neighbor-Joining, maximum likelihood and maximum parsimony shows the individualisation of two species including an intraspecific variability. Following a morphological approach, it is not possible to distinguish the females on the basis of their spermathecae. A new character is proposed: the presence of ontero-lateral teeth of the pharyngeal armature for P. choboudi, never observed in P. riouxi. However, a molecular typing is necessary at the present time for a sure identification of the females. |
