[An approach to the morphology of buccal armature of Sergentomyia nankingensis].
OBJECTIVE
To describe the morphological variation of pointed teeth of buccal armature of Sergentomyia nankingensis in a supplementary study.


METHODS
The morphology of Sergentomyia nankingensis was observed and the specimens included S. nankingensis captured from the field as well as the female ones bred in the laboratory and their offspring of first generation.


RESULTS
The buccal armature of females and males, consists of about 10-19 and 8-15 pointed teeth and the pigmented plate is polymorphous. In the nature, the number of pointed teeth of buccal armature of Sergentomyia is unstable, varying in more than 10 teeth in the same species sometimes.


CONCLUSIONS
Identification of species needs large amount of specimens for comparative observation. Sergentomyia sandfly should be raised separately and individually for morphological observation of its newly emerged offspring, especially when the sandfly specimens and data collected in the field were not sufficient.
