BFBAF410AB74038808582DCF82AA28C2.taxon	description	General description. Medium-sized nematodes, filiform body, cuticle with fine transverse striations along entire body. Males smaller than females. Round cephal ic plate in both sexes (Figs 1 B, 2 B). Deirids symmetrical, simple with rounded tip (Fig. 2 A, C), located immediately posterior to nerve ring. Mouth with two round and simple lateral lips, each with three small teeth on its internal surface; each lip bears a lateral amphid, and a pair of sub-median papillae (Figs 1 B, 2 B). Pharynx short, cylindrical, opening into oesophagus. Oesophagus divided into anterior muscular portion and posterior glandular portion. Excretory pore in anterior region of body, posterior to nerve ring and located at level of division of muscular and glandular oesophagus. Posterior end conical and rounded in both sexes (Figs 1 F, H, 2 D, F). Description of male (based on eight specimens; the number of measurements, where different from eight, is given in parentheses): Total body length (MTBL) 4.85 - 8.03 mm (6.19), width at mid-body 200 - 300 (243). Deirids 150 - 185 (166; n = 7) from anterior end. Nerve ring and excretory pore 100 - 168 (125) and 125 - 295 (179, n = 6) from anterior end, respectively. Pharynx length 23 - 45 (33). Oesophagus total length 613 - 1038 (800, n = 7), muscular portion length 108 - 170 (128, n = 7), glandular portion length 488 - 913 (671, n = 7). Ratio oesophagus total length: MTBL 0.1 - 0.16 (0.13, n = 7). Testis elongated, distributed in zigzag from anterior intestinal portion to posterior region, near cloaca. Caudal alae well developed, bearing ventrally numerous papilliform plates. Cloaca surrounded by numerous papillae (24 - 28), 11 - 14 sessile papillae and 10 - 16 pedunculate papillae distributed asymmetrically in the following arrangement: ventrolateral: 4 - 8 pedunculate on right, 6 - 9 pedunculate on left side; ventral, sessile: 5 - 8 on right and 4 - 8 on left side (Figs 1 F, 2 E, F). Number and disposition of papillae variable with respect to cloaca, thus, precloacal, paracloacal, and postcloacal positions not established. Spicules and gubernaculum absent. Tail 50 - 67 (59, n = 6) long. Description of female (based on ten gravid specimens; the number of measurements, where different from ten, is given in parentheses): Total body length (FTBL) 8.72 - 21.46 mm (14.61), width at mid-body 270 - 440 (349). Deirids 125 - 250 (173, n = 8) from anterior end. Nerve ring and excretory pore 100 - 188 (147, n = 8) and 193 - 343 (256, n = 6) from anterior end, respectively. Pharynx length 30 - 58 (41, n = 9). Oesophagus total length 853 - 1500 (1227, n = 7); muscular portion length 125 - 325 (220, n = 8), glandular portion length 703 - 1220 (996, n = 7); ratio oesophagus total length: FTBL 0.1 - 0.16 (0.14, n = 7). Didelphic, opisthodelphic, ovaries distributed in posterior region of body, uteri extended parallel along almost entire body. Vagina muscular, directed posteriorly, located in anterior region of body close to anterior end of intestine, vulva at 1130 - 2570 (1770) from anterior end (Fig. 1 C). Ratio distance vulva to anterior end of body: FTBL 0.11 - 0.13 (0.12). Tail 25 - 30 (27, n = 8) long. Embryonated eggs occupying almost entire uterus, thick shelled with smooth surface, 39 - 44 (41, n = 15) long by 29 - 33 (31, n = 15) wide (Fig. 1 D); larvated eggs located near vulva, 45 - 50 (48, n = 15) long by 38 - 40 (39, n = 15) wide (Fig. 1 E).	en	Oca, Edgar Uriel Garduno-Montes de, Lopez-Caballero, Jorge D., Mata-Lopez, Rosario (2017): New records of helminths of Sceloporuspyrocephalus Cope (Squamata, Phrynosomatidae) from Guerrero and Michoacan, Mexico, with the description of a new species of Thubunaea Seurat, 1914 (Nematoda, Physalopteridae).
