描述了澳大利亚大堡礁吕宋岛椰子海滩外的一种新种Gnathia masca sp. nov.。雄性的特征是头部有一个浅的背侧沟，延伸到一半的长度，一个轻微的前突，两个锥形的上级额侧突起和一个锥形的下内侧额突。雄花的齿状叶片上有6个突起，内裂片有6或7个细圆齿，顶端突起大。活的雄性、雌性和幼虫的特征是棕色色素沉着，特别是在雄性中，它在眼睛之间形成一条黑色的带，使其看起来像面具。
Gnathia masca sp. nov. is described from material collected off Coconut Beach, Lizard Island, Great Barrier Reef, Aus-tralia. Males are characterised by a cephalosome with a shallow dorsal sulcus that stretches half its length, a slightly pro-duced frontal border with two conical superior fronto-lateral processes and a conical inferior medio-frontal process. Malemandibles have 6 processes on the dentate blade and a distinct internal lobe with 6 or 7 crenulations and a single largedistal process. Live males, females and larvae are characterized by brown pigmentation especially in the male where it forms a dark band that stretches between the eyes, giving it the appearance of a mask.
