Description
Summary:Rhabdochona cascadilla Wigdor, 1918 Synonyms: Rhabdochona sp. of Bangham (1941 partim ); Rhabdochona sp. of Bangham & Venard (1946 partim ) Description (after Byrne 1992a). With characteristics of the genus. General characteristics: outer circle of four cephalic papillae and inner circle of four labial papillae present. Prostom armed with 14 longitudinal sclerotized rods projecting anteriorly as teeth, of which three are dorsal, three ventral, two pairs ventro-lateral, and two pairs dorso-lateral. Sclerotized protuberances present in basal part of prostom [= basal teeth?]. Deirids small, bifurcate, located about the midpoint of vestibule. Male paratypes (means with ranges in parentheses): body 4.5 (4.0–5.1), prostom 0.016 (0.012–0.019), vestibule 0.076 (0.068–0.085), muscular oesophagus 0.159 (0.146–0.227) and glandular oesophagus 1.1 (0.8–1.8) long. Deirids 0.047 (0.039–0.054), nerve ring 0.124 (0.118–0.134) and excretory pore 0.198 (0.182–0.210) from anterior end. Caudal papillae digitiform: 14 to 19 pre-cloacal and 12 (six pairs) post-cloacal, mostly subventral. Phasmids minute, located just distal to most posterior pair of caudal papillae. Left spicule 0.378 (0.320–0.415), its alate portion (blade) 0.171 (0.153–0.190) long. Right spicule 0.118 (0.103–0.128) long, with dorsally projecting barb at distal end, and a bulbous, convex proximal end. Length ratio of right to left spicule 1:3.20 (1:3.11 to 1:3.24). Tail 0.277 (0.212–0.322) long, tapering and ending in pointed tip (Fig. 43 A,B). Female paratypes (means with ranges in parentheses): body 8.4 (6.4–9.9), prostom 0.024 (0.019–0.027), vestibule 0.089 (0.076–0.097), muscular oesophagus 0.198 (0.175–0.227) and glandular oesophagus 1.4 (1.1–1.6) long. Deirids 0.055 (0.050–0.062), nerve ring 0.147 (0.134–0.159) and excretory pore 0.235 (0.200–0.266) from anterior end (Fig. 43 C,D). Vulva near midpoint of body, 4.4 (3.5–5.0) from anterior end (Fig. 43 E). Phasmids minute, posterior to midpoint of tail. Eggs ovoid, smooth, without filaments or floats (Fig. 43 F), 0.017 (0.017– 0.019) x 0.033 (0.031–0.034). Tail 0.228 (0.184–0.287) long, tapering and ending in pointed tip. Comments: the 41 fish species listed below have been reported as hosts of R. cascadilla in Canada. However, according to Byrne (1992a) the numerous reports of this rhabdochonid species “across much of Canada and the United States, from at least 64 species of fish (Byrne 1989) should be accepted with reservation”.
