Eighty-one samples containing 361 crayfishes from the Crustacea Collection of Natural History Museumin Vienna, Austria, were examined for branchiobdellids (crayfish worms). Branchiobdellids were pres-ent in 64 samples: worms and cocoons in 33 samples, only worms in six and cocoons only in 25. Atotal of 240 crayfish worms were recovered and those well preserved were identified: Branchiobdellaastaci ODIER, 1823, Branchiobdella parasites (BRAUN, 1805), Branchiobdella pentodonta WHITMAN, 1882,Branchiobdella hexodonta GRUBER, 1882 and Branchiobdella balcanica MOSZYNSKI, 1937, with B. astacibeing reported for the first time from Austria, Slovenia, Slovakia, and Ukraine. Branchiobdella cocoonswere found on crayfish from European Turkey and the first records of Branchiobdella kozarovi SUBCHEV,1978 on Astacus leptodactylus ESCHOLTZ, 1823 in northwest Asian Turkey and eastern Kazakhstan werereported. Two paratype specimens of Branchiobdella papillosa NESEMANN & FLUTTER, 2002, from the mu-seum were mounted and a microscopical re-description of the species was made.
