- Аннотация: Descriptions are given for the males of Rhaptothyreus typicus Hope et Murphy 1969, a morphologically unique and incompletely investigated deep-sea nematode, using light microscopy, TEM, and SEM. The cephalic sensilla are arranged in 2 circles: an anterior circle consisting of six pairs of papilliform sensilla, and a posterior circle consisting of four papilliform sensilla. The fovea of the giant oblong amphid is covered with cuticle bearing minute perforations. The minute, slit-like, true amphidial aperture revealed only by TEM. The apical oral aperture is reduced to a simple pore, and the vestigial pharynx is devoid of an internal lumen and musculature. A mid-gut is a trophosome consisting of a solid mass of irregularly-shaped cells. Trophosomal cell are filled with rod-shaped structures assumed to be intracellular symbiotic bacteria. There is no evidence of even a vestige of a reproductive system except for the presence of a single spiculum. The phylogenetic relationships of Rhaptothyreus remain unknown.
