Genus Campopera Schellenberg, 1922

Diagnosis.Bodycaterpillar-like;withprosomecylindrical, unsegmented or divided only by constrictions between somites. Urosome narrower than prosome, 4-segmented, consistingof genital complex (fused fifth pedigerous somite and genital double-somite) and 3-segmented abdomen. Caudal rami small; caudal setae obscure or absent. Rostrum well-developed. Antennule broad, 1- or 2-segmented. Antenna 4-segmented, consistingof coxa, basis, and 2-segmented endopod bearing terminal claw. Mandible consistingof coxa and palp; coxa with broad gnathobase bearing teeth on medial margin; palp biramous with 1 setaon basis, 5 setae on exopod; endopod free or fused with basis. Maxillule with 8 or 9 setae on arthrite, 1 on coxal endite, 2 on epipodite; exopod and endopod not articulated from basis, armed with 4 setae each on exopod and on basis-endopod complex. Maxilla 3-segmented, consistingof syncoxa, basis, and unsegmented endopod; syncoxa with 2 or 3 endites; basis withlarge claw plus 1 or 2 setae; endopod atrophied, bearing 2 to 4 setae. Maxilliped lobate with several setae. Legs 1–4 biramous; protopods unsegmented or indistinctly 2-segmented; rami fused with or indistinctly articulated from protopod and unarmed or armed only with minute, papilliform setae. Leg 1 exopod 2-segmented; endopod of leg 1 and all rami of legs 2–4 unsegmented or only with traces of articulations. Leg 5 absent.

Type species. Campopera michaelseni Schellenberg, 1922 by original designation.

Remarks. Schellenberg (1922) described thetype species, C. michaelseni , as an associate of the ascidian Paramolgula gigantea (Cunningham, 1871) collected in the Falkland Islands. In the original description he provided figures of the habitus, rostrum, antennule, and leg 1. Two of the newspecies describedin the presentwork are immediately identifiable as belonging to Campopera , due to their characteristic caterpillar-like body form. The presence of a large claw on the basis of the maxilla, which Schellenberg (1992) mentioned as a diagnostic feature of the genus Campopera , is confirmed in two new species describedbelow.
