A new genus and species of the philometrid nematode Dentirumai philippinensis n. gen., n. sp. Philometrinae, Philometridae, are described on the basis of the female specimens found in the loach goby, Rhyacichthys aspro (Valenciennes), from the upper Bianuan River, Municipality of Casiguran, Aurora Province, in the Philippine Archipelago. Dentirumai philippinensis was collected from the body cavity, subcutaneous tissues near the bases of the pectoral and pelvic fins, and surrounding body tissues in the hypaxial musculature of R. aspro. Based on light microscopic and scanning electron microscopic examination, the new nematode species is morphologically close to the genus Rumai Travassos, 1960 except for one major difference, i.e. the presence of a sclerotized ring in the oral aperture armed with distinct numerous minute teeth on its inner surface. This important taxonomic feature makes it possible to erect a new genus, Dentirumai n. gen. to accommodate the newly discovered philometrid species. A key to genera of the Philometrinae is provided.
基于在菲律宾群岛奥罗拉省卡西古兰市比阿努安河上游的糙吻沙塘鳢（Rhyacichthys aspro，瓦朗谢讷）体内发现的雌性标本，描述了菲尔线虫科菲尔线虫亚科的一个新属新种——菲律宾齿吻菲尔线虫（Dentirumai philippinensis n. gen., n. sp.）。菲律宾齿吻菲尔线虫采自糙吻沙塘鳢的体腔、胸鳍和腹鳍基部附近的皮下组织以及下轴肌肉的周围身体组织。通过光学显微镜和扫描电子显微镜检查，这种新的线虫物种在形态上与1960年的鲁迈属（Rumai Travassos）相近，但有一个主要区别，即口腔中有一个硬化环，其内表面有许多明显的微小牙齿。这一重要的分类特征使得有可能建立一个新属——齿吻属（Dentirumai n. gen.）来容纳新发现的菲尔线虫物种。提供了菲尔线虫亚科各属的检索表。
