Current identification/main database link: Tripodocyrtis elegans Funakawa 1994
The shell is somewhat spiny. The apical horn is unbladed, very weak and shorter than the cephalic height. Pores in the first segment are circular to subcircular and randomly arranged. Axial projection is distinct. The horizontal section of the second segment is somewhat triangular because of three distinct dorsal and lateral ribs. Pores in the second segment are circular to subcircular and randomly arranged, generally they are larger than those of the first segment. Three feet extend downward at the distai end of the second segment. Feet are long, unbladed and almost equal to the diameter of the second segment. The distal end of the second segment is fully open. Remarks.—This species is distinguished from Pseudodictyophimus gracilipes by the absence of the furrows at the ventral side. This species is distinguished from Pseudodictyophimus gracilipes tetracanthus (Popofsky) in Petrushevskaya (1971b) by the unbladed feet. It differs from Dictyophimus platycephalus Haeckel by its weak apical horn and incomplete furrows between the first and second segments. Dictyophimus sp. cf. D. platycephalus Haeckel in Nishimura (1990) has been described as having AD . In this study, although some specimens placed into this species have an indistinct skeleton- like AD , most specimens lack it. Therefore the skeleton-like AD is not stable at the specific level and its existence is regarded as a matter of intraspecific variation within this species.
