Original Description

Sethophænida (vel Dicyrtida multiradiata clausa) with terminal apophyses. Cephalis with a horn.

The genus Clistophaena agrees with the preceding Sethophaena in the mouth of the thorax being closed by a lattice-plate. But the appendages of the thorax are terminal feet, not lateral wings; their number is commonly six or nine, rarely more. Clistophaena may be derived either from Tetrahedrina by interpolation of secondary feet between the three primary, or from Sethamphora by development of a basal lattice-plate closing the mouth.

From the Greek clistophaena = closed shell"

Editors' Notes
[By referring back to p.433 in his Prodromus (Haeckel, 1881a), Haeckel in 1887a apparently meant Clistophaena to be an emendation of the name Clistophatna, which is unjustified according to the provisions of ICZN (1961) art. 33a. Clistophaena is thus a junior objective synonym of Clistophatna Haeckel,1881a.]
