Trois Capillaria (Nematoda) de l'intestin du lérot en France. Rapports avec un Capillaria de l'estomac du sanglier

Abstract

Comparative study of Capillaria from the digestive tract of lerots, Eliomys quercinus (L.), and wild boars Sus scrofa scrofa L., in France : 1) Three species of Capillaria were found in the intestine of lerots. C. myoxinitelae (Diesing, 1851) was rare. C. Iegerae n. sp. was common, closely related to the previous species but distinguished by the following main characteristics : egg shell with a thinner network of surface ornamentations, smaller caudal bursa provided with two pairs of caudal papillae instead of one, spicule with a thinner and regularly pointed extremity instead of a lanceolate extremity. C. alcoveri (Mas-Coma et Esteban, 1985) n. comb. was found only once. It was distinguished from the two previous species by the presence of four pairs of bursal papillae, and an egg shell without surface network. 2) The Capillaria found in the stomach of wild boars was identified as C. myoxinitelae. It appears that this species is fundamentally a parasite of the wild boar, although it was initially described in the lerot.
