Prosomapoda
Clade of arthropods / From Wikipedia, the free encyclopedia
Prosomapoda is a clade of euchelicerates including the groups Xiphosura (horseshoe crabs) and Planaterga (a group comprising bunodids, pseudoniscids, chasmataspidids, eurypterids and arachnids), as well as several basal synziphosurid genera.[1] The clade is defined by the lack of exopods (outer branches) of prosomal appendage II-V in the adult instar,[1] where in contrast the exopods of appendage II-V are well-developed in the non-prosomapod euchelicerates Offacolus and Dibasterium.[2][3]
