   <abstract xml:lang="ru">
    <p>В статье приводится иллюстрированное описание двух новых для науки видов нематод семейства Desmodoridae Filipjev, 1922, обнаруженных на коралловых рифах около берегов Вьетнама. Onyx vulgaris sp. n. по размерам тела и длине спикул близок к O. disparamphis Tchesunov, Jeong, Lee, 2022 и O. orientalis Nguyen Dinh Tu, Nic Smol, An Vangelsen, Nguyen Vu Thanh, 2011. От первого вида, O. vulgaris sp.n. отличается более коротким и менее стройным хвостом, иной формой терминального бульбуса фаринкса, иной формой фовеи амфидов и иной формой преклоакальных супплементов у самцов. От второго вида он отличается более длинными внешними губными щетинками, более коротким терминальным бульбусом фаринкса, более близко к переднему концу тела расположенной вульвой и более длинным рульком. Desmodora coralis sp. n. по размерам тела и отсутствию преклоакальных супплементов у самцов близка к D. scaldensis de Man, 1889, D. macramphis S. Stekhoven, 1950 и D. nini (Inglis, 1963). От всех трех видов отличается более тонким телом и наличием у самцов на вентральной стороне хвоста бугра с порой.</p>

    <p>Two new nematode species of the family Desmodoridae Filipjev, 1922, found in coral reefs in Vietnam, are described and illustrated. Onyx vulgaris sp. n. in body size and spicules length is close to D. disparamphis Tchesunov, Jeong, Lee, 2022 and O. orientalis Nguyen Dinh Tu et al., 2011. It differs from first species by the comparatively shorter and less slender tail, different form of terminal bulb of pharynx, different form of amphidial fovea and differs form of precloacal supplements in males. It differs from second species by the longer inner labial setae, shorter terminal bulb of pharynx, close to anterior body end located vulva and longer gubernaculum. Desmodora coralis sp. n. close to D. scaldensis de Man, 1889, D. macramphis S. Stekhoven, 1950 and D. nini (Inglis, 1963) in body size and absence of precloacal supplements in males and differs from all three species by the thinner body and presence of tubercle with pore on ventral side of tail in males.</p>
