Genus Porcellidium Claus, 1860 Type species . Porcellidium viride (Philippi, 1840). Diagnosis [an alternative (apomorphic) character state is known for all characters marked with an asterisk]. Spermatophore elongate* (sausage shaped), female receives only one spermatophore during her life span, usually deposited on ventral surface of the genital double-somite at time of metamorphosis from stage V copepodid to adult, attachment to female ephemeral (shed before egg laying starts); bodY oval*, dorsoventrallY compressed*; male cephalosome truncated anteriorly*, female not truncated anteriorlY*; animals do not conglobate*; dorsal organs absent*, no massive honeYcomb-like cuticle; hYaline border surrounds cephalosome*, marginal glands open dorsal to hYaline border*; female genital double-somite broad*, divided into anterior and posterior lobes*, rounded posteriorlY*, lateral striations absent*; male genital somite never fused to metasome segment 4 and P5 baseoendopod*; female caudal ramus rectangular*, setae T1 to T4 always present* (T1 may be recessed), never pinnately clavate or evenlY spaced*; no ridge-plates on labrum*; six setae on maxillule endopod*; maxilliped coxae touch in midline*, basis with fimbriate process*; limbs P2, P3, P4 with three external spinous setae on exopod segment 3*; P5 shorter than genital double-somite*, ventral expansion absent*; male antennule segment 3 setae δ and δ' alwaYs present*, anterior comb absent*, blade or knob-like ventral process may be present, segment 4 with three denticles*, brush-pad never present*; male P5 trapezoid with six setae*.
