Summary:Taenia talicei Dollfus, 1960 (Figs. 1–14) Type host : Ctenomys torquatus Lichtenstein, as established by the original description of the metacestode by Dollfus (1960). Other hosts: C . talarum Thomas and C . australis Rusconi. Microhabitat: Abdominal cavity. Definitive host: Canis lupus familiaris Linnaeus (experimental infection); natural definitive host unknown. Type locality: Uruguay. Other localities: Mar de Cobo (Mar Chiquita, 37º58´S, 57º34´W) and Las Grutas (Necochea, 3833´S, 5845´W), Buenos Aires Province, Argentina.

Scolex 631 123 (450–860) long and 1.017 176 (710–1.210) wide bearing four rounded muscular suckers 273 31 (220–330) in diameter (Figs. 1–2). Rostellum armed with two rows of hooks; small hooks 168 26 (150–187), large hooks 237.50 7 (232–242). Total number of hooks 46 (44–50) (Figs. 1–4). Male genitalia (meristic data and morphological description of male genitalia based on serial sections and whole specimens, measurements of male genital system corresponding to 5 proglottids from 3 worms): Testes oval, 124–138 in number, 65 (42–77) long, 54 (35–67) wide. Testicular field not extending laterally beyond osmoregulatory canals. In mature proglottid, cirrus pouch elongated and curved, reaching poral osmoregulatory canals, 157 18 (132–175) long and 121 6 (112–125) wide; coiled cirrus inside (Figs. 5–6). Vas deferens highly coiled; coiled region extends well into the medulla (Fig. 5). Male and female genital ducts pass between the ventral and dorsal longitudinal excretory canals (Fig. 7). Female genitalia (meristic data and morphological description of female genitalia based on serial sections and whole specimens, measurements of female genital system corresponding to 5 proglotids from 3 worms): In mature segments, ovary bilobed; poral lobe 450 61 (360–480) by 350 28 (304–360) smaller than antiporal lobe 590 23 (48–60) by 580 76 ...
