Müller, 1906

Diagnosis
Large, fragile species. Carapace lateral aspect subrectangular but tapering slightly anteriorly (C. dasyophthalma Habitus 1, C. dasyophthalma Habitus 3). Shoulder vaults well developed, sharp edged (difficult to see in damaged specimens). Carapace covered with faint vertical striations. Both dorsal and ventral corners are rounded. The right asymmetrical gland opens just posterior to the mid-length, on a well defined process. The left asymmetrical gland opens just ventrally of the postero-dorsal corner.
Female, frontal organ partially differentiated, about double length of first antenna, capitulum finely spinose (C. dasyophthalma 1). Second antenna endopodite "a" and "b" setae both finely spinose (C. dasyophthalma 2).
Male, frontal organ stem slightly longer than first antenna, capitulum hirsute (C. dasyophthalma 3). First antenna, "a" seta S-shaped at base, almost as long as limb, "c" almost as long as second podomere, "b", "d" and "e" setae subequal, "e" seta armature numerous pairs of fine hair-spines, "b" seta with a few coarse spines (C. dasyophthalma 4).

Remarks
Poulsen, 1973 placed this characteristic species in the genus Paraconchoecia originally established by Claus to include Conchoecia oblonga (Conchoecia oblonga), C. spinifera (Conchoecia spinifera), C. inermis (Conchoecia inermis) and C. elegans (Conchoecia elegans) (= gracilis sensu Claus). Like many of Poulsen's designations to this genus, this species does not fit well.

Distribution
Probably occurs in all oceans at depths >2500m. In the Atlantic it is known from 0°-53°N. 1, 2 (R.R.S. Discovery Map).

Type specimens
None designated; status of original material uncertain.

Type locality
Original material collected from the tropical Atlantic at 0°N 6°W.
