From: Embryonic neurogenesis in Pseudopallene sp. (Arthropoda, Pycnogonida) includes two subsequent phases with similarities to different arthropod groups

Figure 1

Two hypotheses on the phylogenetic position of Pycnogonida within Arthropoda. Left phylogram: Traditional placement of pycnogonids as sister group to Euchelicerata, both taxa forming the Chelicerata. Right phylogram: Alternative placement of pycnogonids as sister group to all remaining arthropod lineages, the latter representing the Cormogonida. Note the unresolved position of Myriapoda.
