Lobosorchis tibaldiae Miller & Cribb, 2005 Metacercariae (Fig. 2) Hosts: Neoglyphidodon melas (Cuvier), Perciformes, Pomacentridae, bowtie damselfish; Pomacentrus melanochir (Bleeker), Perciformes, Pomacentridae, Indonesian damsel. Locality: Heron Island, Great Barrier Reef (23 º 26 ’S; 151 º 54 ’E), Queensland, Australia. Site: Flesh. Deposited specimens: vouchers G 230576 –G 230578. Description: Based on 3 specimens. Body oval, longer than wide, 388 (328–426) long by 238 (163–289) wide; length/width ratio 1.7 (1.5–2). Oral sucker 64 (63–65) long by 111 (80–128) wide. Oral spines 60 (54–65), length 11 (8–15). Ventral sucker 42 (40–45) long by 42 (38–43) wide. Ratio oral/ventral sucker width 2.6 (2.1–3). Forebody occupying 37 (35–40)% of body length. Prepharynx 11 (6–13) long. Pharynx 39 (35–45) long by 49 (45–53) wide. Ventral sucker/pharynx width ratio 0.9 (0.8–0.9). Oesophagus 21 (16–26) long. Intestinal bifurcation dorsal to or immediately anterior to ventral sucker. Intestinal caeca blind, 398 (286–494) long, terminate midway between ventral sucker and posterior end of body or close to posterior end of body. Testes multiple, in two symmetrical groups of 4–5, in mid-hindbody, individual testes 21 (14–29) long by 22 (14–29) wide. Gonotyl a small lobe arising from anterior wall of ventrogenital sac, often undeveloped. Genital pore immediately anterior to ventral sucker. Ovary deeply lobed, immediately anterior and adjacent to testes, 22 (16–26) long by 26 (18–35) wide. Laurer's canal present. Vitelline system undeveloped.
