Description

Elongate worms with spined tegument. Total length 1200–3880 (mean 2360); maximum width 216–440 (324). Oral sucker subterminal, 140–240 × 120–200 (212 × 162), usually slightly longer than wide. Prepharynx absent. Pharynx subglobular, 40–84 × 40–72 (66 × 58); oesophagus 100–280 (179) long. Intestinal bifurcation at middle of first third of body. Caeca asymmetric, right longer than left, terminating blindly at end of middle third of body. Ventral sucker in anterior third of body, 88–180 × 80–140 (132 × 108); sucker ratio (maximum diameter OS:VS) is 1:0.5–0.8 (1:0.6). Genital pore median or submedian, in forebody, near intestinal bifurcation, located at 240–660 (461) from anterior end. Testes oblique, pre-equatorial, smooth; anterior 80–200 × 60–180 (147 × 116); posterior 80–200 × 60–160 (144 × 112). Cirrus-sac dorsal to ventral sucker, extending from acetabular region to genital pore, 100–240 (160) long, 48–88 (65) wide; length:width ratio 2.3–2.7:1 (2.5:1). Ovary entire, post-testicular, lateral, sinistral, 60–120 × 48–100 (89 × 74). Vitelline follicles in lateral fields, occupying middle third of body; follicles paracaecal, variable in number, shape and size. Uterus long, with extensive descending, ascending and transverse coils throughout post-testicular region; distal coils pass between testes. Eggs 38–44 × 28–34 (41 × 31). Excretory bladder V-shaped. Excretory pore subterminal, asymmetrical.

Type-host: Gallotia atlantica (Peters and Doria) . Hosts deposited in the herpetology collection of the Department of Animal Biology of the University of Barcelona ( Spain).

Site: Small intestine.

Type locality: Yaiza (28 ° 56 ∞ N; 13 ° 46 ∞ W), Island of Lanzarote, Canary Islands, Spain .

Material studied: Thirty-five individuals. Type-specimens deposited in The Natural History Museum, London (H 2000.5.5.1; P 2000.5.5.2) and Department of Animal Biology, University of Valencia (nos. LZ-64.18,19; 117.12,13,28,34,40)
