    Caligus solea n. sp (Copepoda: Caligidae) parasitic on the common sole Solea solea (Linnaeus) from the north-eastern Mediterranean off the Turkish coast
    (Springer, 2014) Demirkale, Ibrahim; Ozak, Argun A.; Yanar, Alper; Boxshall, Geoffrey Allan
    A new species of caligid copepod, Caligus solea n. sp., is described from the common sole Solea solea (Linnaeus) caught off the north-eastern Mediterranean coast of Turkey. Both sexes of the parasite were collected from all over the upper body surface of its host. The new species belongs to the macarovi-group of species as established by Boxshall & Gurney (Bull Br Mus (Nat Hist) (Zool), 39:161-178, 1980), with which it shares the following four characters: (i) leg 4 with two-segmented exopod, distal segment carrying three apical spines but no lateral spine; (ii) distal exopodal segment of leg 1 with three plumose setae posteriorly plus four distal margin elements, spine 1 naked, spines 2 and 3 with accessory process and spine 4 about twice length of the others; (iii) females with one-segmented abdomen while males with two-segmented abdomen; (iv) male maxilliped with myxal process opposing the tip of the subchela. However, the new species differs from its congeners within the macarovi-group in the number of sensillae on each papilla on and around the postantennal process, and also in the absence of serrations along the distal margin of the maxilla. This is the twenty-eighth species of Caligus to be reported from the Mediterranean Sea.

    Lernanthropid copepods parasitic on marine fishes in Turkish waters, including two new records
    (Magnolia Press, 2016) Ozak, Argun Akif; Demirkale, Ibrahim; Yanar, Alper
    A review of Lernanthropidae (Copepoda: Siphonostomatoida) recorded on marine fish species in the Mediterranean and Turkish seas is presented together with the first records of two species of the genus Lernanthropus de Blainville, 1822 that are new to the Turkish coasts. The newly recorded parasites are: Lernanthropus gisleri van Beneden, 1852 from the gill filaments of Umbrina cirrosa (Linnaeus, 1758) and Lernanthropus callionymicola El-Rashidy & Boxshall, 2012 from the gill filaments of the Red Sea immigrant dragonet Callionymus filamentosus Valenciennes, 1837. General morphology, measurements and key diagnostic characters of both species are presented, based on light and scanning electron microscopy. In addition, some contradictions are noted in previous descriptions of L. gisleri and some newly observed structural details of L. callionymicola are also presented.
