Rhabditidae sp. 1

( Figs 4 View FIGURE 4 A, B; Table 2 View TABLE 2 )

The three dead females (ZIHU 3325-3327) obtained were infested and colonized by fungi inside their bodies ( Fig. 4 View FIGURE 4 A, B).

Head rounded with no constriction, lateral lips with small amphidial aperture. Stoma cylindrical; cheilostom not sclerotized, glottoid apparatus isomorphic, metastom with two warts. Pharyngeal corpus with muscular median bulb. Reproductive system amphidelphic; vulva transverse, located near midbody. Rectum short, 0.9–1.1 abd length. Tail conical, 6.0–7.3 abd length.

The specimens resemble Caenorhabditis ( Osche, 1952) Dougherty, 1953 in general features of the body.

Characters: a,b,c, de Man's ratios; V, position of vulva as a percentage of the body length from anterior end. * Value in ZIHU 3325 (L= 849).
