V. Kiseliene et al., ON MORPHOLOGY AND CHAETOTAXY OF CERCARIA-ABYSSICOLA WESENBERG-LUND, 1934 (DIGENEA, ECHINOSTOMATIDAE), Acta Parasitologica, 42(1), 1997, pp. 7-11
A rare echinostome cercaria - Cercaria abyssicola Wesenberg-Lund, 1934
is redescribed on the base of the material found in Valvata piscinali
s from the lake Asveja in Lithuania. Description of the cercaria is co
mpleted with data concerning the number of collar spines (equal to 45)
, structure of excretory system and pattern of chaetotaxy. Some detail
s are also added to the morphology of redia and metacercaria. The taxo
nomic status and possible affinities of the species are discussed.
