Within the Pandaridae, representatives of Prosaetes, Cecrops, Luetkenia, Philorthagoriscus, Orthagoriscicola, and Entepherus are considered members of the Dinemoura-group based on their shared possession of a narrow third pedigerous somite and dorsal plates on the fourth pedigerous somite in the adult female and a modified leg 3 terminal endopodal segment in the adult male.
SEM analysis of females, males and the three types of eggs: The anterior ventral plate of the lorica contains two oval borders jointed to the lateral spines that in turn join the ventral and dorsal plates. Two rounded spines are present in the ventral posterior: in the female these form a semi-circular boarder from which emerges the foot.
