摘要

A new species of caligid copepod, Caligus adanensis sp. nov., is described based on one male and three female specimens collected from the body surface of garfish, Belone belone (Linnaeus, 1760), caught in the Mediterranean Sea, off the south-eastern coast of Turkey. The new species belongs in the Caligus macarovi group of species as established by Boxshall and Gurney (1980) and recently updated in Boxshall (2018), as it shares the following set of characters: (i) leg 4 with 2-segmented exopod, carrying only three apical spines on distal segment; (ii) distal exopodal segment of leg 1 bearing three plumose setae posteriorly plus four distal elements, with spine 1 naked, spines 2 and 3 each with accessory process, spines 1 to 3 of similar length, and seta 4 about twice the length of the others; (iii) females with a 1-segmented abdomen but males with a 2-segmented abdomen; (iv) male maxilliped with a myxal process opposing the tip of the subchela; (v) maxilla with spinules on the posterodistal margin of the brachium; and (vi) unisensillate papillae associated with the post-antennal process. The new species differs from other members of the group by a combination of characteristics that include (1) a large, prominent cuticular swelling present near the basal segment of the female antenna; (2) antenna with posterior process on the proximal segment; (3) the sternal furca has long, slightly divergent tines that are slightly expanded and incurved at the tip; (4) the second endopodal segment of leg 3 carries a small subtriangular, papilliform process on its ventral surface; (5) the male maxilliped has a prominent bilobate myxal process bearing corrugations on the surface of the larger lobe and two unequal, spiniform projections on the subchela in addition to the proximal seta at the base of the claw; and (6) body proportions of the new species differs from its congeners.
