Enchodelus macrodurus ( De Man, 1880) Thorne, 1939

Measurements:

Females (n = 15): L = 1.38 — 1.54 (1.46) mm; a = 21 — 26 (24); b = 4.0 — 4.9 (4.4); c = 57 — 73 (63); cÕ = 0.5 — 0.7 (0.6); V = 41 — 43 (42); G1 = 13 — 15; G2 =14 — 15; lip region width = 17 — 19 (18) m; lip region height = 6 — 7 (7) m; amphidial aperture = 9 — 12 (10) m; odontostyle = 42 — 47 (45) m; odontophore = 42 — 48 (45) m; guiding ring = 27 — 33 (29) m; neck length = 304 — 361 (331) m; expanded part of pharynx = 116 — 144 (130) m; cardia = 9 — 13 (10) m long; prerectum = 114 — 222 (152) m; rectum = 30 — 36 (34) m; ovary = 55 — 133 (78) m; oviduct = 78 — 117 (98) m; uterus = 80 — 113 (94) m; tail = 20 — 29 (24) m; ABD = 38 — 43 (41) m.

Location of pharyngeal gland nuclei and their orifices: D = 65 —66; AS1 = 17 — 20; AS2 = 25 — 30; PS1 = 56 — 58; PS2 = 56 ­ 58

Habitat and locality: Soil from grassland and shrubs from Banbiyan of Shengnonjia mountains, Hubei Province, P. R. China

Remarks: Thorne (1939) designated E. macrodorus as the type species of his newly proposed genus Enchodelus because of its widespread distribution in Europe and in USA. Jairajpuri and Loof (1968) reported a single specimen from Srinagar, India with a comparatively anterior location of vulva ( V = 37 vs 41 — 46 in European specimens). Ahmad and Jairajpuri (1980) provided a detailed description of the species based on fifteen females collected from high altitudes in India. In these specimens the vulva position was same as those of European populations. The Chinese population agrees fairly well with the European as well as Indian populations.
