A NEW TRIAENOPHORID TAPEWORM, MILANELLA FAMILIARIS N. GEN. AND N. SP. (CESTODA: BOTHRIOCEPHALIDEA),
June 27th, 2008 | by admin |A NEW TRIAENOPHORID TAPEWORM, MILANELLA FAMILIARIS N. GEN. AND N. SP. (CESTODA: BOTHRIOCEPHALIDEA), FROM BLACKFISH CENTROLOPHUS NIGER.
Milanella familiaris n. gen. and n. sp. (Bothriocephalidea: Triaenophoridae) is proposed to accommodate a new cestode from blackfish Centrolophus niger (Gmelin) (Perciformes: Centrolophidae). Milanella is characterized by: trapeziform, markedly craspedote proglottids with a velum-like posterior margin and horn-like lateral projections; pyriform uterine sac in the first gravid proglottids; arrow-shaped scolex with well developed apical disc and prominent posterior margins; strobila containing intensively stained corpuscles most numerous in its anterior part; deeply lobated ovary; absence of a neck; a large, pyriform, thin-walled cirrus-sac with the proximal part bent anteromedially; vagina posterior to the cirrus-sac; and cortical vitelline follicles. Milanella most closely resembles Bathycestus Kuchta and Scholz, 2004, Pistana Campbell and Gartner, 1982, and Probothriocephalus Campbell, 1979, differing mainly in the shape of proglottids and uterine sac.
