Abstract
The fine structure of the trifoliate process of three species of Atherigona were studied. The outer surface of the lateral lobe of the process for the three species, A. bedfordi, A. hyalinipennis and A. secrecauda is covered with a dense mat of hairs. There are spine-like outgrowths on their inner surface referred to as “commasets” as well as some unusual sensilla on the rim of the lateral lobe and the section connecting the lobes to the stem. These structures showed inter-specific variation. The stem of the process is glabrous and granulate in A. bedfordi and A. secrecauda, but sparsely pilose in A. hyalinipennis.
Résumé
La structure raffinées du procédé trifoliate des trois espèces de l’Atherigona ont été recherchées. L’extérieure du lobe lateral du procédé des trois espèces: A. bedfordi, A. hyalinipennis et A. secrecauda, est couvert d’une natte épaise des poils. Il y a des excroissances rassemblantes des épines à l’intérieur qu’on appelle des “commasets”, aussi bien que certaines rares sensilla au bord du lobe lateral et la section qui rattache les lobes à queue. Ces structures ont exposé à la variation interspécifique. La queue du procédé est glabreux et granulée avec A. bedfordi et A. secrecauda, mais d’une mainère poilue éparse avec A. hyalinipennis.
