Diagnosis : Dorsum black or dark-brown; median stripe pale yellow to grayish, thin and sometimes interrupted, becoming whitish and wider next to posterior tip; eyes dorsal with clear halos; glandular border with three cell types ; mc:h, 17%-19%; pharynx cylindrical; esophagus conspicuous; esophagus: pharynx ratio, 27%-37%; anteriormost testes posterior to ovaries; most posterior testes near root of pharynx; sperm ducts opening into end of proximal region of vesicle; prostatic vesicle, mainly globose, extrabulbar with two distinct regions: a forked, laterally expanded and ventrally disposed ental region and a large unforked ectal region; ejaculatory duct sinuous; male atrium long, intensely folded, with two main regions; ovovitelline ducts emerging dorsally from end of posterior half of ovaries, uniting ventrally to the female atrium; common glandular ovovitelline duct almost vertical, slightly anteriorly arched; female canal posteriorly directed and slightly recurved; female atrium oval-elongate, highly folded; length of male atrium, approximately two times that of female atrium; gonopore canal slightly posteriorly inclined; male and female atria with independent musculatures; dorsal elongated fold separating male and female atria.
