Andrya Railliet, 1893 em end Diagnosis: Monieziinae Spassky, 1951. Strobila ribbon-like, with numerous segm

ents. Scolex unarmed. Excretory system simple, with dorsal and ventral canals bilaterally connected with one anastomose. Genital pores alternating in sets or irregularly. Vagina opening in genital atrium posterior to orifice of male duct. External and internal seminal vesicle present. Testes numerous, distributed aporelly or between ventral excretory canals, sometimes overlapping ventral excretory canals. Uterus between ventral excretory canals or beyond this, at first mucose, near ovarium, ventrally, not transverse, becoming expressively reticulate in mature segments and filling the gravid segments. Eggs with pyriform apparatus. Parasites of Lagomorpha, ? Rodentia. Structure of the genus Andrya Railliet, 1893 1. Andrya rhopalocephala (Riehm, 1881) Railliet, 1893 (Fig. 5 and 34-39)Syn. : Taenia rhopalocephala Riehm, 1881, Anoplocephala rhopalocephala (Riehm, 1881) Blanchard, 1891. Original host: LepusJimidus, Europe, Holotype: does not exist. Comments: The species is known from many hosts of the genus Lej>us_and Oryj^olagjos^ distributed in Europe, North Africa and Central Asia (for more details see SPASSKY, 1951). It is still the only described species in the genus Andrya whose uterus is not across or is not beyond the ventral excretory canals. Since its original description the species A. rhopalocephala has been re-described many times, see e.g. STILES (1896), BAER (1927), JOYEUX and BAER (1936), SPASSKY (1951), GVOZDEV, KONTRIMAVICHUS, RHYZIKOV, SHALDYBIN (1970), TENORA and MURAI (1978). The species is conspicuous in its external morphological variability of the mature segments (compare e.g. BAER, 1927; GVOZDEV et al., 1970, TENORA and MURAI, 1978). 2. Andrya cuniculi (Blanchard, 1891) Railliet, 1893 (Figs 3 and 4). Syn. : Taenia rhopaliocephala Riehm, 1881, Anoplocephala cuniculi Blanchard, 1891, Mo- niezia cuniculi (Blanchard, 1891) Blanchard, 1893, Paranoplocephala cuniculi (Blanchard, 1891) Tenora et Murai, 1980. Original host: Oryctolagu s funiculus, Europe West. Holotype: does not exist. Comments: The species has been re-described well e.g. in the studies of STILES

(1896), ARNOLD (1938), BAER (1927), most recently in the study of TENORA, MURAI, VALERO and CUTILLAS (19811982). It is conspicuous in its external morphological variability of the mature segments (compare e.g. BAER, 1927; SPASSKY, 1951; TENORA, MURAI, VALERO and CUTILLAS, 1981-1982). From the ecological point of view it is interesting that (provided it has not been introduced) predominant are findings of this parasite in mammals of the genera Lepus_and Ory_ctolagus in the western part of the palaeartic region. According to some authors (e.g. ERHARDOVÁ, 1958) it is very difficult to distinguish the species A. rhopalocephala and A. cuniculi. It was TENORA and MURAI (1980) - even though they incorrectly classified the species A. cuniculi into the genus Paranoplocephala - who were the first to define exactly the differences between the above-mentioned species (the uterus beyond the ventral excretory canals in A. cuniculi, the uterus not across, not beyond the ventral excretory canals in A. rhopalocephala)

. The recent study of TENORA and CUTILLAS (1983) provides more detailed data about the species A. cuniculi. Notes: In one of earlier studies (see TENORA, MURAI and VAUCHER, 1984) we drew attention to the fact that our transferring some species of the genus Andrya in the genus Paranoplocephala
