Les sensilles des larves nageantes des Monogènes du genre Polystoma peuvent être classées en groupes et en cycles transversaux.
L’étude de trois espèces européennes montre que les deux générations de larves issues, l’une de l’adulte, l’autre du néoténique, ont la même chétotaxie, que la variation individuelle est extrêmement limitée et que certaines espèces voisines peuvent être distinguées par des variations de détail sur un schéma fondamental.
Abstract
The sensillae of the swimming larvae of the Monogeneans of the Polystoma genus can be classified into groups and transversal cycles.
The study of three european species shows that the two generations of larvae, one of them coming from the adult, the other one from the neotenic, have the same chetotaxy, that there are very few individual differences from one larva to the next, and that closely related species can sometimes be distinguished by minor variations within a fundamental pattern.
