description: <i>Marbefia,</i> gen. n. urn:lsid:zoobank.org:act: 5B070367-A759-44B2-931C-7D9A49AC6AC4 <b>Diagnosis.</b> Laophontidae. Body linear, not dorsoventrally depressed. Integument of cephalothorax and body somites covered with tiny spinules; posterior margins of somites smooth, with spinule rows dorsally and ventrally. Rostrum delimited at base; broadly triangular, prominent. Genital double-somite &amp;female; with lateral incisions and ventrolateral internal chitinous ribs marking original segmentation. Pleural extensions of &amp;female; abdominal somites well developed. Caudal ramus cylindrical, subrectangular and as long as wide; inner margin with long spinules; with 7 setae; setae IV and V well developed, pinnate; seta VI reduced, setiform. Anal operculum spinulose. Sexual dimorphism in antennule, P3–P4 endopods, P5, P6 and in genital segmentation. Antennule slender and 7-segmented in &amp;female;; 8-segmented and subchirocer with 3 segments distal to geniculation in ♁; segments with spinular ornamentation along anterior margin of segments 1–4 in &amp;female; and 1–3 in ♁; segments 1–2 without processes; with aesthetasc on segment 4 (&amp;female;) or 5 (♁); acrothek on apical segment consisting of 2 setae and one aesthetasc. Antenna with 4 setae on exopod; allobasis with abexopodal seta. Mandibular palp elongate, 1-segmented; with one basal, one exopodal and 3 endopodal setae. Maxillule with defined exopod bearing 2 setae. Maxilla with 3 endites on syncoxa; endopod represented by 4 setae. Maxilliped elongate; syncoxa with 2 setae; basis without distinct ornamentation; endopodal claw long and curved, with one accessory seta. P1 long, with elongate coxa and basis; with 3-segmented exopod, exp-2 1.6 times as long as exp-1, exp-3 with 2 short and 2 geniculate setae; endopod stout, enp-1 without inner seta, enp-2 with minute seta and long minutely denticulate claw. Swimming legs P2–P4 with 3-segmented exopods and 2-segmented endopods. P2–P4 enp-2 swollen, with double row of flimsy setular extensions along outer lateral margin (except for P 4 in ♁); inner seta of P3–P4 enp-1 present in &amp;female; but absent in ♁. P3 enp-2 produced into straigth spiniform apophysis in ♁ (homologous with outer spine of enp- 2 in &amp;female;). Armature formula of swimming legs 2 to 4 (P2–P4) as follows: P5 with separate exopod and baseoendopod. Exopod elongate with 6 setae in &amp;female; and 4 setae in ♁. Endopodal lobe well developed in &amp;female;, subrectangular, with 5 setae. Baseoendopods fused medially in ♁; endopodal lobes rudimentary, with 2 setae each. P6 forming well developed operculum with 2 small setae in &amp;female;; asymmetrical in ♁ (with dextral or sinistral configuration), with outer distal corner produced into conical process bearing 2 well developed elements. <b>Type and only species.</b> <i>Pseudonychocamptus carthyi</i> Hamond, 1968 = <i>Marbefia carthyi</i> (Hamond, 1968), comb. n. <b>Etymology.</b> The name of the new genus honours the advances in our understanding of marine ecosystem functioning stimulated by the MarBEF Network of Excellence in Marine Biodiversity and Ecosystem Functioning. Gender: feminine.
