The nematode Rumai rumai Travassos, 1960 (Philometridae) is redescribed from the tissues of the mouth, tongue, operculum and head of the arapaima, Arapaima gigas (Schinz) (Osteichthyes), from Mexiana Island, Amazon River Delta, Brazil. Additional data on the related Nilonema senticosum (Baylis, 1922) from the same host and locality are also presented. Rumai rumai is characterized by the presence of a sclerotized formation on the female cephalic end, dorsal and ventral cephalic projections, the shape and structure of the oesophagus and a conical caudal extremity. Males of both R. rumai and N. senticosum, specific parasites of the ancient arapaima fish in the Neotropics, remain unknown. The relationship between these tissue-dwelling nematodes and the aquaculture system of Mexiana Island is commented upon.
1960年发现的线虫鲁迈鲁迈线虫（Rumai rumai Travassos），现根据巴西亚马逊河三角洲墨西拿岛的巨骨舌鱼（Arapaima gigas (Schinz)，硬骨鱼纲）口腔、舌头、鳃盖和头部组织重新描述。文中还提供了来自同一宿主和地点的相关糙皮尼洛线虫（Nilonema senticosum (Baylis, 1922)）的补充数据。鲁迈鲁迈线虫的特征是雌性头部末端有硬化结构、头部背侧和腹侧有突出物、食管的形状和结构以及圆锥形尾端。鲁迈鲁迈线虫和糙皮尼洛线虫均为新热带区古老的巨骨舌鱼的特定寄生虫，其雄性仍不为人知。文中还讨论了这些组织内寄生线虫与墨西拿岛水产养殖系统之间的关系。
