Description
Summary:Arctocestus n. g. (Fig. 13) Etymology. The name of the new genus refers to the Arctic distribution of A. serratus and its hosts, Dicrostonyx spp. “ Arctocestus ” is masculine. Diagnosis. Strobila of moderate dimensions. Scolex small, distinctly separate from neck. Suckers directed laterally or antero-laterally. Neck narrow (absolutely and relative to scolex width), of variable length. Length/width ratio of mature proglottids ca. 25%. Proglottids craspedote, with pronounced, protruding velum, giving strobila characteristic serrate appearance. Genital pores unilateral or infrequently (and irregularly) alternating. Genital ducts pass dorsal to longitudinal osmoregulatory canals. Ventral longitudinal osmoregulatory canals wide. Testes antiporal, most poral testes may reach midline of proglottid, i.e. level of antiporal lobe or middle of vitellarium. Several testes regularly positioned lateral to antiporal ventral longitudinal canal. Testes slightly overlapping ovary. Cirrus sac long and wide, with prominent ... : Published as part of Haukisalmi, Voitto, Hardman, Lotta M., Hoberg, Eric P. & Henttonen, Heikki, 2014, Phylogenetic relationships and taxonomic revision of Paranoplocephala Lühe, 1910 sensu lato (Cestoda, Cyclophyllidea, Anoplocephalidae), pp. 371-415 in Zootaxa 3873 (4) on page 389, DOI: 10.11646/zootaxa.3873.4.3, http://zenodo.org/record/229232 ...
