Type: Boxshallia bulbantennulata Huys, 1988. Total: 1 sp.

Diagnosis after R. Huy (1988, p.139) :
- Prosome 5-segmented with posterior margin of Mxp-bearing somite not produced into carapace-like expansion.
- 1st pedigerous somite exposed.
- Urosome 5-segmented in female ; genital double-somite without any trace of subdivisions.
- A1 with conspicuous swelling at the outer side of segment 1 ; 27-segmented in female with aesthetascs on segments XI, XVI and XXVII ; 23-segmented in male, unigeniculate between segments XIX and XX, with aestherascs on segments XI, XVI and XXIII.
- Exopod of A2 7-segmented ; endopod indistinctly 3-segmented
- Md palp biramous ; basis with 3 setae ; endopod 2-segmented ; exopod 3-segmented.
- Mx1 with 1-segmented rami ; epipodite with 7 setae.
Praecoxa and coxa of Mx2 with 2 endites each ; endopod 3-segmented.
- Mxp with 4 endites on syncoxa and with 6-segmented endopod.
- Coxa of P1 wkthout inner spine ; endopod 3-segmented.
- Distal exopod segment P1-P4 with 3 outer spines.
- Distolateral angle of 2nd endopod segment bifid in P2-P4.
- P5 biramous, endopod represented as a bipinnate spine ; exopod 2-segmented ; with distinct intercoxal sclerite and coxa in female ; positioned midventrally in male.
- Caudal ramus with 6 setae.

The new genus can be distinguished from all other misophrioids by the presence of the bulb-shaped process on the 1st antennular segment of both sexes. This structure is already discernible in the copepodite I stage. In spite of the profound condensation of the proximal segments, the primitive 27-segmented condition is still recognisable.
The new genus is unique in the presence of 3 setae on the basis of Md. Another unusual feature is the presence of 4 setae midway along the inner margin of the proximal endopod segment. A high number of armature elements occurrs also on different parts of Mx1. The new genus is unique amongst misophrioids in lacking an inner spine on the coxa of P1 in both sexes. The new genus shows a bifidprocess on the distolateral angle of the 2nd endopod segment of P2-P4; this detailed structure is also present in most deep-sea genera, however, not always on the same legs.
