Cymothoida Wägele, 1989

Remarks. At subordinal level, following Brandt & Poore (2003), the apomorphic states of the anterolateral and ventral attachment of the uropodal peduncle, which articulates ventro-laterally, and the ventrally flat pleotelson unambiguously identifies the suborder as Cymothoida. The plesiomorphic state of five free (unfused) pleonites is a further consistent character, with occasional fusions of pleonites in some Cirolanidae, notably the highly derived cave-dwelling genera (see Bowman, 1975; Botosaneanu et al., 1986; Bruce & Herrando-Pérez, 2005; Iliffe & Botosaneanu, 2006).
