Male adults of gnathiid isopods (Crustacea; Isopoda; Gnathiidae) have remarkably developed rectangular-shaped cephalosomes and mandibles in most species. Tenerognathia visus Tanaka, 2005 belongs to a monospecific genus having remarkable characters in male morphology; reduced mandibles and large eyes occupying the whole of an elliptical cephalosome. The original description of T. visus is based on male adult specimens from coral rubble. This study found adult males and their larvae of T. visus attracted by light. Furthermore, specimens of female adults were observed by laboratory rearing of praniza larvae. In this study, morphologies of larvae and female adults of T. visus are described and notes on mating behavior in a laboratory aquarium are provided.
颚虱等足类动物（甲壳纲；等足目；颚虱科）的成年雄性在大多数物种中具有显著发达的矩形头节和颚。2005年的田中视颚虱属于一个单种属，在雄性形态上具有显著特征；颚退化，大眼睛占据整个椭圆形头节。视颚虱的原始描述基于来自珊瑚碎块的成年雄性标本。本研究发现视颚虱的成年雄性及其幼虫受光吸引。此外，通过对前茗幼虫的实验室饲养观察到了成年雌性标本。在本研究中，描述了视颚虱幼虫和成年雌性的形态，并提供了在实验室水族箱中的交配行为记录。
