Re-study of the type species of the genus Humes, 1999 (Copepoda, Cyclopoida, Schminkepinellidae) described from the Pacific Ocean (Juan de Fuca Ridge), and study of the species from a deep-sea hydrothermal vent field on the Central Ridge in the Indian Ocean revealed a derived feature and widespread geographic distribution of this deep-sea genus of cyclopoids. The derived feature of is the sexually dimorphic third endopodal segment of leg 3 possessing a small outer terminal spine together with spine-like outgrowths on this segment. The new species differs from Humes, 1999 in not expressing sexual dimorphism in leg 5, having three spines and one seta on its exopod in both sexes ( has three spines and one seta on the female exopod but three spines and two setae on the male exopod) and in having broader caudal rami which are 8.9 times longer than wide in the female (this ratio for is 11). An amended diagnosis of the genus , a key and a table of morphological differences for all species of Schminkepinellidae are given.
对1999年休姆斯属（桡足亚纲，剑水蚤目，施明克平内利科）的模式种进行重新研究，该模式种采自太平洋（胡安德富卡海岭），同时对印度洋中脊一个深海热液喷口区的该属物种进行研究，结果揭示了剑水蚤目这一深海属的一个衍生特征及其广泛的地理分布。其衍生特征为第3对胸足的内肢第3节存在两性异形，该节具有一个小的外侧端刺以及该节上的刺状突出物。该新物种与1999年的休姆斯属物种不同之处在于，第5对胸足无两性异形，两性的外肢均有3根刺和1根刚毛（休姆斯属雌性外肢有3根刺和1根刚毛，而雄性外肢有3根刺和2根刚毛），并且尾叉更宽，雌性尾叉长为宽的8.9倍（休姆斯属的这一比例为11）。给出了该属的修订诊断、检索表以及施明克平内利科所有物种的形态差异表。
