Branchiobdellida (Annelida: Clitellata) Found in the Crayfish and Annelid Collections of the French National Museum of Natural History (Paris), and on Recently Collected Crayfishes from France

摘要

Thirty one samples from the Zoothece collection in the French National Museum of Natural History in Paris consisting of 71 crayfishes were checked for branchiobdellidans (crayfish worms). As a result 79 crayfish worms from 11 of the samples were found, separated and identified. The identified worms included three European species: Branchiobdella astaci ODIER, 1823, Branchiobdella parasita HENLE, 1835 and Branchiobdella hexodonta GRUBER, 1882. These species were found on crayfishes collected in France (B. astaci), Greece (B. parasita, B. hexodonta), Montenegro (B. astaci) and Ukraine (B. astaci). The Asian species, Branchiobdella kobayashi YAMAGUCHI, 1934 was found in the gills of Cambaroides dauricus (PALLAS, 1773) from Amur, Russia. In addition 11 samples with a total of 19 crayfishes collected by Mr. Pierre Noel from France, and six samples with a total of 41 crayfishes sent by Mr. P. Gotteland and two samples of a total of five crayfishes sent by Mr. Th. Duperray also from France were checked for epibionts. As a result B. astaci was found in two of the samples and B. hexodonta, a new record for this country, was found in one of the samples. Xironogiton victoriensis GELDER AND HALL, 1990 was found in a sample of Pacifastacus leniusculus (DANA, 1852). The identification of Branchiobdella specimens on four prepared slides in the Museum's collection was checked and the misidentified specimens were labelled correctly.
