) such as the number of articles on AI and AII, presence of a male antennal organ on the second article of AI, number of exopod articles on the thoracopod, basipod of male ThVIII with teeth and without setae, the presence of a large endopodal spine on the uropod sympod. The two species are also similar in size, ranging between 1 and 1.8 mm, with females being larger than males in both species. However, both species can be easily distinguished by the antennal organ and the morphology of the lobes on ThVIII in both males and females. The other differences are numerous but more subtle, making them potentially more difficult to discern; however, considered altogether, they reveal two distinct species. In general, these differences relate to relative proportions among articles, specific patterns of setation and relative sizes of setae and spines on AI and AII, mouthparts and other appendages such as the thoracopods, uropod and furca.
