Garlitska, Lesya, George, Kai Horst & Chertoprud, Elena S., 2022, A new species of Breviconia Conroy-Dalton & Huys, 2000 (Copepoda: Harpacticoida: Ancorabolidae Sars) from the Bering Sea, northern Pacific Ocean (Russia), European Journal of Taxonomy 813, pp. 103-122 : 106-107

Genus Breviconia Conroy-Dalton & Huys, 2000

Generic diagnosis (amended from Conroy-Dalton & Huys 2000)

Ancorabolinae . Body slightly depressed dorsoventrally, tapering posteriorly, with no clear demarcation between prosome and urosome. Cphth slightly broader than long, with moderately developed sensillar groups I–V and with small conical processes. Rostrum small, fused to cphth, basally constricted, with rounded or bifid tips bearing 1 tube pore and 2 sensilla. All body somites except the penultimate somite and the telson with a pair of backwards produced lateral wing-like and spinulose processes and laterodorsally with paired tubercles or small conical processes. P2 and/or P3–P4 and/or P5-bearing somites additionally with dorsolateral and dorsal tubercles or processes. All tubercles/processes bearing a sensillum at their tips. The female’s last thoracic and first abdominal somite fused, forming GDS. Anal operculum dorsally with small spinules laterally flanked by a pair of sensilla arising from small knob-like tubercles. A1 of female 3-, of male 7-segmented, subchirocer. Antennular segments smooth or densely covered with minute spinules. Aes on segments 2 and 3 (female) and 4 and 7 (male), respectively. A2 with allobasis, lacking exopods but carrying 2 abexopodal bipinnate setae. Endopod with 2 rows of spinules on the outer margin, and with spinulose frill subapically; apically with 1 short spine and 4 setae, 3 of which geniculate; additionally, with 1 small seta fused to the outermost apical seta. Md slender, with unarmed coxa, gnathobase elongated and curved by nearly 90°; md palp 1-segmented, with 1 (basal), 1 (exopodal) and 3 apical (endopodal) setae. Mxl with 1–2 setae on coxal endite; basis with 3 and 2 setae on proximal and distal endite, respectively; exo- and endopod completely reduced and represented by 2 and 1 setae, respectively. Mx with 2 syncoxal endites, each equipped with 2 apical setae; basis with 4 elements, the largest of which produced a strong claw-like spine; endopod represented by 2 setae. Mxp prehensile, slender; syncoxa unarmed or bearing few spinules subapically, without setae; basis longer than syncoxa, with a longitudinal row of long spinules; endopod drawn out into a long, slender lacking the usual accompanying minute seta. Swimming legs with slender, bow-like intercoxal sclerites and transversely elongated bases. P1 with 2-segmented exo- and endopod; basis carrying 1 inner and 1 outer bipinnate seta; exopod smaller than endopod, exp-1 with 1 outer spine, exp-2 with 2 outer spines and 3 geniculated setae. P2–P4 with 3-segmented exo- and endopods; basis with 1 outer bipinnate seta; exps-1 and -3 without inner setae, exps-3 with 2 outer spines/setae and 2 apical setae. In the female, endopods 2-segmented, with the first segment small and unarmed; enp-2 with 1 inner and 2 apical setae, in P3 and P4 additionally with 1 outer seta. Male P2 endopod like in the female; the P3 endopod is 3-segmented, with the first and third segment being small; enp-1 unarmed, enp-3 with 2 apical setae; enp-2 elongated, with strong curved apophysis on its inner apical edge. Male P4 enp-2 lacking inner seta. P5 of female with endopod fused to basis, forming a baseoendopod, whose endopodal lobe is elongated and bears 2 inner and 2 apical setae. Exopod distinct, approximately twice as long as the endopodal lobe, with 2 outer spines, 2 apical setae, and 1 densely bipinnated inner seta. Female genital field with ventrally located gonopores in the middle of the somite. P6 small, forming genital operculum, with 2–3 setae. Caudal rami elongated, approximately 3–7 times as long as the broadest width and equipped with 7 setae.
