Dorsiceratus Drzycimski, 1967

Type species: D. octocornis Drzycimski, 1967 .

Additional species: D. triarticulatus Coull, 1973 , D. ursulae George, 2006 , D. wilhelminae sp. nov., D. dinah sp. nov. (both described here).

Generic diagnosis. Ancorabolinae Sars, 1909, Ceratonotus -group sensu Conroy-Dalton (2001). Body long, slender. Cphth frontally with peak, lacking lateral processes. Rostrum constricted, fused to cphth, square or rectangular in shape, with terminal pair of sensilla and single tubepore. Cphth and free thoracic somites with dorsal pair of spinulose cuticular processes at their distal margins, which bear single sensilla at their bases and tips. Thoracic somites bearing P2–P5 with dorsal single tubepores. Last thoracic somite and abdominal somites also with dorsal tubepores in differing numbers. Genital double somite present in female, with dorsal suture indicating former separation. Telson broader than long, trapezoid in shape. Anal operculum with row of spinules. FR of different length, with 7 setae, with terminal tubepore, furcal seta I minute. Female A1 4-segmented, male A1 5–6-segmented. A2 with allobasis bearing 2 abexopodal setae. Md with variable gnathobase and 1-segmented palpus bearing 4–5 setae. Mxl with coxa and basis distinct or fused. Mx with 2 endites, each with 2–3 setae, syncoxa and basis distinct or fused. Mxp prehensile, syncoxa with 1 terminal seta, enp formed into a long claw with associated minute seta. Swimming legs 1–4 with transversely elongate bases and with exp and enp. P1 exp 2–3-segmented, in case of 2-segmented exp first outer spine of terminal segment may be translocated subterminally. Terminal segment with 4–5 geniculate setae. P1 enp not prehensile, 2-segmented, enp2 terminally with 1–2 setae. P2–P4 with 3-segmented exps and 2-segmented enps, enp1 much shorter than enp2. P5 enp completely reduced and represented by 1–2 setae that are accompanied by 1–2 tubepores. Outer basal seta arise from small setophore and are associated with a long tubepore. Exp distinct or fused to benp, with 5 setae, 1 long tubepore may be present subterminally.
