Cymbasoma pedroi Suárez-Morales and Mercado-Salas sp. n. (Figures 3, 4) Material examined Holotype. One adult female (ZMH K-62094), partially dissected, semi-permanent slide mounted on glycerine, sealed with acrylic nail varnish; deposited in the Crustacea Collection of the Museum of Nature Hamburg, Zoology. Specimen with cephalothorax partially twisted and both antennules broken off from sampling or previous manipulation and preservation. Material collected off the coast of north-west Iceland; Cruise IceAge 1, Station M 85/3-1104 (66°38.600̍N, 024°31.970̍W), collected 13 September 2011 by Saskia Brix. Type locality North-west Iceland (66°38.600̍N, 024°31.970̍W). Epibenthic sledge trawled at a depth of 118.8 m. Etymology The species name is dedicated to our colleague and friend Prof. Dr Pedro Martinez Arbizu (Senckenberg Research Institute) for his relevant contributions to the systematics of the Copepoda. Name in genitive case; the gender is masculine. Diagnosis Cymbasoma with robust, medially expanded cephalothorax, forehead anteriorly produced into subtriangular swelling, with wrinkled surface, antennules absent in holotype except for first segment; genital somite with conspicuous rounded protuberances on posterolateral margins; anal somite more than half as long as genital double-somite, with deep constriction on outer margins. Fifth leg bilobed, endopodal and exopodal lobes fused, forming thick cylindrical ramus armed with three subequally long setae; inner protuberance representing endopodal lobe unarmed, located close to distal margin of fifth leg ramus. Description of adult female Body shape and tagmosis as usual in female Cymbasoma (Suárez-Morales and McKinnon 2016). Total body length of holotype individual = 2.07 mm, measured from anterior end of cephalothorax to posterior margin of anal somite. Cephalothorax length = 1.02 mm, representing about 49% of total body length (Figure 3). Oral cone located 0.18 of way back along ventral surface of cephalothorax (oc in Figure 3).
