Fig. 1.
Joyeuxiella gervaisi (Setti, 1895) scolex from domestic cat from Dubai, UAE. The stinkhorn-shaped rostellum consists of a slender and longer stalk and conical shaped armed cap.
Fig. 2.
Joyeuxiella gervaisi (Setti, 1895) rostellum armed with rose-thorn hooks from domestic cat from Dubai, UAE.
Fig. 3.
Joyeuxiella gervaisi (Setti, 1895) from domestic cat from Dubai, UAE, mature segment. The anterior end of the segment is occupied by convolutes of vasa deferens (bar: 100 μm).
Fig. 4.
Joyeuxiella gervaisi (Setti, 1895) gravid segment from domestic cat from Dubai, UAE. Egg capsules are located between longitudinal excretory vessels (bar: 500 μm).
Fig. 5.
Cylindrical jar ‘Cest 254’ of the zoological museum of University of Naples. This vessel contains the cestodes collected by E. Setti. The host Gazella abyssinica is wrong.
Fig. 6.
Label taken from inside of the jar ‘Cest 254’. Here, the spelling of the host is correct but the species name, Dipylidium gervasi, name is misspelled.
Fig. 7.
Maximum-likelihood tree (partial mitochondrial COI) computed through MEGA-X software based on kimura-2 parameter and 1000 bootstrap replicates. Taenia hydatigena was taken as the outgroup. The geographical origin and host from which the sequence was identified are also mentioned. Bootstrap values are given as number on the nodes. The sequences for Joyeuxiella gervaisi and Joyeuxiella pasqualei retrieved in this study are depicted in red.
