, new genus and species, is described from 15 specimens (14.0-27.2 mm SL) collected from shallow (0-9 meters) intertidal and sub-tidal waters of the Rangitāhua Kermadec Islands, New Zealand. The new taxon is distinguished from all other members of the Gobiesocidae by a combination of characters, including a heterodont dentition comprising both conical and distinct incisiviform teeth that are laterally compressed with a strongly recurved cusp, an oval-shaped opening between premaxillae, a double adhesive disc with a well-developed articulation between basipterygia and ventral postcleithra, and many reductions in the cephalic lateral line canal system. The new taxon is tentatively placed within the subfamily Diplocrepinae but shares a number of characteristics of the oral jaws and the adhesive disc skeleton with certain members of the Aspasminae and Diademichthyinae.
新属新种是根据从新西兰朗伊塔胡克马德克群岛潮间带和潮下带浅水区(0 - 9米)采集的15个标本(体长14.0 - 27.2毫米)描述的。这个新分类单元通过一系列特征与喉盘鱼科的所有其他成员区分开来,这些特征包括:具有异形齿列,包括圆锥形和独特的切牙状牙齿,这些牙齿侧向压缩,有强烈弯曲的尖端;前颌骨之间有椭圆形开口;有一个双吸盘,在基鳍骨和腹侧后匙骨之间有发达的关节;以及头部侧线管道系统有许多简化。这个新分类单元暂时置于双褶喉盘鱼亚科内,但在口颌和吸盘骨骼方面与某些无臂喉盘鱼亚科和冕喉盘鱼亚科成员有一些共同特征。
