Material examined. 1$, Buk-myeon , Uichang-gu, Changwon-si, Gyeongsangnam-do, South Korea (GPS coordinates: 35°22′22.5″N, 128°36′47.3″E) GoogleMaps , extracted by sieving and the Baermann funnel method from potato farm soil. The specimen (slide No. NIBRIV0000862892) is deposited at the National Institute of Biological Resources , South Korea .
Measurements. See Table 1.
Description. Female: Body cylindrical, length 529.5 μm long, ventrally curved after fixation ( Fig. 1A View Fig ). Cuticle annulated; annuli 2.0 μm wide and 1.0 μm thick at mid-body. Lateral field occupying 22.2% of width of body at mid-body. Lateral incisures varying in number along body length: three incisures between procorpus region and deirid, branching off from deirid into five incisures ( Fig. 1B View Fig ); two incisures fading out between anus and phasmid region; three incisures extending to tail terminus ( Fig. 1C View Fig ). Head region continuous with neck. Lip region 7.5 μm in diameter, with triradiate symmetry with 6 + 4 papillae ( Fig. 1D View Fig ). Three pairs of asymmetrical lips; pairs of lips separated by U-shaped primary axils. Guarding process absent. Cephalic probolae absent. Three low and rounded labial probolae present. Stoma cephaloboid; length 1.6 times the lip region diameter ( Fig. 1B View Fig ). Cheilorhabdions oval-shaped. Small dorsal denticle on metastom. Pharyngeal corpus fusiform with swollen metacorpus, 3.1 times isthmus length. Isthmus narrower than corpus, distinctly demarcated from metacorpus. Basal bulb oval-shaped with well-developed valves; 1.4 times as long as its width. Cardia inconspicuous, surrounded by intestinal tissue. Nerve ring located in posterior corpus, at 63.7% of pharynx length. Excretory pore position at posterior corpus, at 63.8% of pharynx length. Position of deirids in lateral field at anterior isthmus, at 71.5% of total neck length. Reproductive system monodelphic-prodelphic ( Fig. 1E View Fig ). Vulva lips not protruding. Vagina length 0.6 times body diameter. Post-uterine sac 2.6 times body width. Uterus length 3.2 times body diameter. Spermatheca 1.9 times body width. Oviduct short. Ovary straight, with a single row of oocytes. Rectum length 1.5 times anal body diameter ( Fig. 1C View Fig ). Tail conoid, with truncated terminus. Phasmids located middle of tail, at 48.1% of tail length.
Male: Unknown.
Distribution. Denmark ( Bussau, 1991), Israel ( Steiner, 1936), Mongolia ( Andrássy, 1967), Malawi ( Siddiqi et al., 1992), South Korea (this study), Spain ( Abolafia and Peña-Santiago, 2003), and USA ( De Ley et al., 1999).
Habitat. Soil sample from a potato farm.
Remarks. Morphological characters of the specimen described in this study generally agree with previous studies ( Steiner, 1936; Siddiqi et al., 1992; De Ley et al., 1999; Abolafia and Peña-Santiago, 2003), except for total body length (529 vs 613-1,530 μm), the ratio of body length to body width (a = 27.2 vs 15.0-24.3), the ratio of total body length to pharynx length (b = 3.4 vs 4.0-7.8) and corpus to isthmus ratio (3.1 vs 3.3-7.2). Although these morphometric measurements of the specimen examined from a single individual differ from A. bodenheimeri , they are considered intraspecific variations as previously reported from many other Acrobeloides species ( Anderson, 1965; 1968; Boström and Gydemo, 1983; De Ley et al., 1999; Abolafia and Peña-Santiago, 2003). Morphometric analysis using multiple nematode individuals is further required to delimitate morphological variation of the species.
