| Reference | Diagnosis | |
|---|---|---|
| E. P. Anderson et al. 2025 | Bivalved arthropod with two tagmata. Near circular to
ellipsoid valves attached anteriorly in vicinity of fourth or fifth cephalic somite. Remaining hinge disconnected from cephalon. Valves covering posterior three to four head appendages. Unira- mous antennae on second and third somites. Robust, annulated, coarsely setose primary antennae extending anterodistally, can recurve posteriorly. Second antenna on third somite delicate and elongate with closely set rows of setae. Posterior three cephalic limbs elongate and somewhat flexible with at least two rows of filamentous setae. The third of these elongate appendages, found on the sixth somite, noticeably smaller compared to two preceding it. Short trunk, 10 13 segments decreasing in width posteriorly. Raised central ridge along dorsal tergites. Small pleurae extending posterodistally from each tergite. Homogenous bifurcated rod-like or uniramous paddle trunk limbs. Trunk terminating with reduced telson. |
