Torquatoides noerdjitoi n.sp.

( Figs. 17–28 )

General description. Body elongate, slender, with fine transverse striations. Lateral alae absent. Mouth surrounded by 2 lateral pseudolabia. Four or five teeth on internal surface of each pseudolabium. Cuticular collar consisting of circular row of plaques posterior to labia. Six plaques in anterior row, 12 in posterior row. Each posterior rounded plaque with one papilla. Amphids on anterior lateral plaques. Buccal capsule long, cylindrical. Oesophagus divided into short anterior muscular part and longer posterior glandular part; muscular part 3.6–4.1% TBL in male, 1.2–2.2% TBL in female; glandular part 14.4–17.6% TBL in male, 8.7– 11.8% TBL in female. Nerve ring around anterior part of muscular oesophagus. Cervical papillae and excretory pore immediately anterior to nerve ring.

Male (n=2). Body length 5.77–6.32 mm, maximum diameter 70–90 µm. Cephalic extremity 23–30 µm diameter. Buccal cavity 58–63 µm long. Nerve ring 150–190 µm, excretory pore 130–140 µm, and cervical papillae 105–110 µm from anterior end, respectively. Anterior muscular oesophagus 210–260 µm long, 20–30 diameter; posterior glandular oesophagus 0.83–1.11 mm long, 35–40 µm diameter. Distance between striations at mid-body 6.2–6.8 µm. Caudal alae well developed, symmetrical 375–390 µm long, 35–45 µm wide. Eleven pairs of pedunculate caudal papillae, eight preanal and three postanal; first preanal papillae 280– 340 µm from posterior end of body. One pair of small papillae near tail tip. Spicules dissimilar, unequal; left relatively long and slender, 308–320 µm long, with pointed tip, right thick and short, 120–125 µm long, with a crescent-shaped tip. Ratio of spicule lengths 1:2.56–2.57. Gubernaculum straight on dextral side, coniod on sinistral side, 34–37 µm long. Tail 71–80 µm long.

Female (n=5). Body 11.00–24.00 mm long, 80–100 µm maximum diameter. Cephalic extremity 28–42 µm wide. Buccal cavity 71–80 µm long. Nerve ring 160–210 µm, excretory pore 140–170 µm, and cervical papilla 120–130 µm from anterior end, respectively. Oesophagus with short anterior mucular part and long posterior glandular part; anterior part 240–290 µm long, 18–30 µm in diameter; posterior part 1.30–2.10 mm long, 50–80 µm diameter. Vulva 2.26–6.24 mm from posterior end. Tail digitiform, 122–160 µm long. Eggs elongate, 60–65 µm long, 10–13 µm wide, unembryonated in uteri.

Host. Batrachostomus javensis javensis (Horsfield, 1821) . (Aves: Caprimulgiformes: Podargidae )

Site of infection. under the lining of the gizzard

Prevalence. 1/1

Intensity. 2 males and 5 females

Type locality. Jalur Apai, Gunung Ciremai National Park, West Java, Indonesia (6 0 55’S, 108 0 22’E, elevation 1,700m)

Type specimens. Holotype, male ( MZB Na 406); allotype female ( MZB Na 407); paratypes, one male, 4 females ( MZB Na 408)

Etymology: The new species is named after M. Noerdjito (MZB) for help provided in the collection of the specimens.

Remarks. Six species of Torquatoides have been reported from birds (Zhang and Brooks, 2004): Torquatoides torquata (Gendre, 1922) in Centropus monachus Ruppell, 1837 from Africa; T. balanocephala (Gendre, 1922) in Merops malimbicus Shaw, 1806 from Africa and M. orientalis Latham, 1802 from India; T. bengalensis Nandi and Majumdar, 1987 in C. sinensis (Stephens, 1815) from India; T. crotophaga ( Williams, 1929) in Crotophaga ani (Linnaeus, 1758) from Central America ( Panama), C. sulcirostris and Geococcyx californianus from South Texas ( USA), and Guira guira from Brazil; T. singhi (Rasheed, 1960) in Dicrurus macrocercus Vieillot, 1817 from India and T. trogoni Zhang and Brooks, 2004 in Trogon massena Gould, 1838 from Costa Rica.

The new species can be distinguished from T. torquata , T. bengalensis , and T. crotophaga in lacking lateral alae. Among the species lacking lateral alae, the new species differs from T. balanocephala in having 12 versus 8–10 posterior cuticular plaques posterior to the labia and 8 versus 13–17 pairs of precloacal papillae. T. noerdjitoi n. sp. differs from T. singhi in having a longer body (males 5.77–6.32 mm long, females 11.00–24.00 mm in the new species versus males 2.9 mm long, females 7.52 mm long in T. singhi ), 8 versus 10 pairs of precloacal papillae, longer spicules (left spicule 308–320 µm long, right spicule 120–125 µm long in the new species versus 107 µm long and 77 µm long, respectively, in T. singhi ), and egg size (60–65 µm long by10–13 µm diameter in the former versus 28 µm long by 19 µm diameter in T. singhi ). The new species resembles with T. trogoni in the body length and ratio of spicule lengths, but differs in having 8 instead of 21– 22 pairs of pre-cloacal papillae, in the shape of right spicule and in the shape of gubernaculum.
