( Figs. 1–2 View FIGURE 1 View FIGURE 2 )
Type host. Indotestudo elongata (Blyth) (Reptilia: Testudines ).
Type locality. Hebei Normal University, Shijiazhuang, Hebei Province, China (114°29’ E; 38° 03’ N).
Site of infection. Intestine (from fecal mass)
Type specimens. Holotype: male (HBNU-1009), allotype: female (HBNU-1010), paratypes: 2 males (HBNU- 1011) and 2 females (HBNU-1012).
Prevalence and intensity. 1 infected / 1 examined, 9 specimens.
Etymology. The species is named in honor of Professor Puqin Wang of Fujian Normal University for his contribution to the parasitic nematodes.
Description. Body stout, cylindrical. Cuticle finely transversely striated. Lateral alae present and narrow, beginning near nerve ring in both sexes, ending just anterior to caudal alae in male and extending to posterior to anus in female. Mouth opening triangular, surrounded by three lips not demarcated from body. Inner edge of each lip with one anterior cuticular flange. Subventral lip flanges triangular, dorsal lip flange rounded with one indentation on the anterior edge. Dorsal lip with two large lateral outer papillae and two tiny inner papillae, subventral lips each with two tiny inner papillae, one large and one small lateral outer papillae, and one amphid ( Fig.1 View FIGURE 1 . C). However, in SEM observation, tiny inner papillae were not seen, and three other papillae were observed located on outer side of amphid in each subventral lip, these papillae should be somatic papillae which distorted by dehydration procedure ( Fig. 2 View FIGURE 2 . A, B). Esophagus includes three parts: short pharynx, long corpus and posterior bulb.
Male: Body 7.64–8.82 (8.28) mm long and 540–590 (570) wide. Pharynx 80–90 (90) long, corpus 1.03– 1.25(1.18) mm long, bulb 250–300 (280) long and 180–260 (220) wide. Nerve ring 590–740 (670) and excretory pore 740–900 (850) from the anterior end, respectively. Caudal end curved ventrally. Tail with the pointed tip, 290– 380 (330) long. Precloacal sucker with distinct sclerotized rim, 78 in diameter, 90–130 (100) anterior to the cloaca. Caudal alae supported by three pairs of large papillae including two pairs at level of precloacal sucker and one pair lateral to cloaca. Other caudal papillae consisting of 8 pairs precloacal, ventrolateral in position; 5 pairs adcloacal; 7 pairs postcloacal in position, 5 ventrolateral, 2 dorsolateral (first pair arranged asymmetrically, sixth pair double). Spicules equal and nonalate, tessellated just at two thirds of distal part, promixal end smoothly (fig. 1. I), 740–930 (830) long. Gubernaculum present, 50–60 long and 24–27 wide.
Female: Body 7.60–9.02 (8.11) mm long, 490–570 (520) wide. Pharynx 80–100 (90) long, corpus 1.24–1.47 (1.37) mm long, bulb 220–300 (270) long and 220–290 (260) wide. Nerve ring 490–590 (530) and excretory pore 710–830 (760) from the anterior end, respectively. Vulva anterior to the middle of body, 3.14–4.02 (3.45) mm from anterior end, anterior lip of vulva protruded forming a flap. Vagina muscular, leading posteriorly into common uterus, this latter dividing into two uteri. Uteri parallel, leading posteriorly, flexing anteriorly and connecting with oviducts and coiled ovaries. Eggs oval with thick, smooth shells, in one-cell stage of development in uterus, 60–80 (70) long and 30–50 (40) wide. Tail pointed, 590–670 (610) long.
