[Synopsis of a four-year research on the "maculipennis" complex (author's transl)].

The authors have carry out during four summers a study of the "maculipennis complex" on the Languedoc-Roussillon coast line. They have determined three sibling species: Anopheles maculipennis subalpinus (very abundant, with an important eggs ornementation' poly-morphism), Anopheles maculipennis maculipennis (found only once in that region) and Anopheles maculipennis atroparvus found only the last year of our research.
