ABSTRACT
The tapeworm species Bertiella satyri from a semi-wild Sumatran orangutan (Pongo abelii: Ponginae) is redescribed and the sequence of its 18S rDNA is presented. The tapeworms parasitizing the genera Pan, Pongo, Homo and Hylobates from Muséum National d'Histoire Naturelle, Paris and from Muséum d´Histoire Naturelle, Genève are also presented. The validity of B. satyri is confirmed. B. satyri (BSA) differs from the most similar species Bertiella studeri (BSTU) in the following characteristics: (1) testes number, BSTU 300-400; BSA 116-124, (2) genital opening, BSTU regularly alternate; BSA irregularly alternate, (3) Cirrus-sac, BSTU short, 0.250-0.320, does not reach excretory ducts; BSA long, 0.630 × 0.495, reaches excretory ducts, (4) egg size, BSTU 0.053-0.060; BSA 0.030-0.051, (5) host BSTU Pan troglodytes, Africa; BSA Pongo pygmaeus, P. abelii, Indonesia (Borneo, Sumatra). Both species differ according to our material and the name B. satyri (Blanchard, 1891) is resurrected.

The present study presents the description of Oochoristica beveridgei n. sp. (Linstowiinae Fuhrmann, 1907). The species was found in the small intestine of Tarentola parvicarinata Joger (Gekkonidae) in East Senegal (West Africa). Among known species of Oochoristica Lühe, 1898, O. beveridgei is most similar to Oochoristica junkea (Johri, 1950) Schmidt, 1986, found in Gekko gecko (Linnaeus) from India. A common feature of both species is the location of the cirrus sac, which lies anterior to the poral part of the ovary. The new species differs from O. junkea in having a higher number of testes, different testes arrangement, wider cirrus sac, and a different shape of ovary. The position of the cirrus sac in O. beveridgei is also similar to that found in Oochoristica gallica Dollfus, 1954, whose host is Psammodromus hispanicus Fitzinger (Lacertidae) from Morocco. The new species differs from O. gallica in that it possesses fewer testes and that these testes have a different arrangement. The location of the cirrus sac in O. beveridgei is also similar to that seen in Oochoristica bivitellolobata Loewen, 1940, whose host is Cnemidophorus sexlineatus (Linnaeus) (Teiidae) from the United States. The latter species has a higher number of testes, with only half of the cirrus sac located anterior to the poral part of the ovary, and possesses a divided vitellarium.

Andrya cuniculi (Blanchard, 1891) (Cestoda: Anoplocephalidae) is redescribed from Oryctolagus cuniculus (L.) from Spain. Large ranges of variability in body length and width, testes number and position of the cirrus sac were observed. An external seminal vesicle covered with small glandular cells is present. The pattern of development of the uterus is similar to that of Andrya rhopalocephala (Riehm, 1881). The only reliable differential characters to distinguish A. cunliculi from A. rhopalocephala are the position of the uterus in gravid segments and the position of the testes in mature segments. The uterus of A. cuniculi occupies the median field and parts of the lateral fields but is restricted to the median field in A. rhopalocephala. Testes are distributed more symmetrically lateral to the female organs in A. cuniculi but are mostly antiporal in A. rhopalocephala.
