Females are described for the first time in the genus Sensiava Markhaseva & Schulz, 2006, that was known previously only from males. Four species of this genus are identified from samples collected in the vicinity of the abyssal sea bed. Two species, Sensiava secunda sp. nov. and S. peculiaris sp. nov. are named, and two species are not given names due to a poor condition of the examined specimens and their incomplete descriptions. Sensiava males have also been found in the samples. They share with their male congener Sensiava longiseta Markhaseva & Schulz, 2006 a geniculate right antennule, which is a plesiomorphy observed only in the benthopelagic Clausocalanoidea Giesbrecht, 1893. A differential diagnosis for the genus is given, based on both sexes. Sensiava was previously known only from the Antarctic waters between 63-64ºS, but its distributional range now can be extended significantly further to the north, up to the Equator in the South Atlantic.
在2006年的Sensiava属（Markhaseva和Schulz）中首次描述了雌性，该属此前仅知有雄性。从深海海床附近采集的样本中鉴定出该属的四个物种。命名了两个物种，即Sensiava secunda sp. nov.和S. peculiaris sp. nov.，另外两个物种由于所检查标本的状况不佳及其描述不完整而未命名。在样本中也发现了Sensiava属的雄性。它们与同属雄性Sensiava longiseta Markhaseva & Schulz, 2006一样，具有膝状的右触角，这是仅在1893年的底栖浮游性Clausocalanoidea中观察到的一种原始特征。基于两性给出了该属的鉴别诊断。Sensiava属以前仅在南纬63 - 64度之间的南极水域被发现，但现在其分布范围可以显著向北扩展，直至南大西洋的赤道地区。
