On the presumed phylogenetic position of the Xiphocarididae (Decapoda, Caridea) based on the larval morphology of Xiphocaris elongata

First zoeal stage of the crab Domecia acanthophora (Desbonne, in Desbonne & Schramm, 1867) (Decapoda, Brachyura) and revision of the larval morphology of superfamily Trapezioidea

“…Marques et al, 2003;Barros-Alves et al, 2013;Guerao et al, 2014). According to phylogenetic analysis, Clark and Ng (2010) suggested that the genera Domecia, Quadrella Dana, 1851, Tetralia Dana, 1851and Trapezia Latreille, 1828 are nested in one clade that is defined by the absence of seta 3.5 and seta 3.4 on the third endopodal segment of the second maxilliped (for details, see Clark and Guerao, 2008), and should be according to a synapomorphy defines the Domecia + Tetralia + Trapezia clade: the presence of one subterminal seta on the distal endopod segment of the maxillule (vs. two subterminal setae).…”
