( Fig. 21 , 23 A~ E )

Measurements. Female (n = 13): L= 1614 μm+ 98 (1470 1765); a = 28.7± 2.1 (25~ 31.6); b=4.8± 0.4(4.3~ 5.9); c = 53. 6 ± 4.2(47.4~ 62.5); V=50.5%±1. 5 (48.4~ 54.5); Odontostyle=37 μm+ 1. 5(35 ~40.1); Odontophore= 41.1 µm+ 2.2(37.2~ 43.8); Rectum=35 μm ± 3.5 (31.3~43); Prerectum=168.5 µm± 9.5 (153.3~178.8); Head to guiding ring = 25 μm+ 1.0(23.3~27); Oesophagus length = 343.1 µm+ 16.8(318~ 370); Tail length = 29 µm± 2.7(25.5~ 33.5); Body width=56.5 μm± 4.5 (52~67); ABW =41.1 μm+ 3.9(36~ 47).

Female: Body tapering anteriorly to narrow lip region; posteriorly to a sub-hemispheroid tail and slightly ventrally arcuate. Lips low. obscure, offset. Amphids escutcheon shaped. Spear massive with broad flanges. Guiding ring double; 23~ 27 μm from anterior end. Oesophagus enlarged by abrupt expansion near middle. Cardia elongate-hemispherical. Prerectum length three times body width. Rectum length slightly shorter then the anal body diameter. Ovaries reflexe about halfway to vulva. Vulva transverse, heavily cuticularized. Tail hemispherical to bluntly conoid with 10~ 15 pairs of ' saccate bodies,

Discussion.: General shape similar to Korean specimens of E. hopedorus but differs from these specimens, by the presence of basal flanger at the odontophore E. macrodorus is very similar but the tail usually contains 10~ 15 pairs of saccate bodies.
