Peloridiomorpha Heteroptera - (unranked) The name Prosorrhyncha is a name (proposed by Sorensen et al. 1995) for a suborder of Hemiptera, comprising a grouping of the traditional taxon "Heteroptera" plus its sister taxon, the family Peloridiidae (often classified as a suborder itself).
There is no agreement on the status of this taxon, as there are two competing classifications regarding this branch of the Hemiptera; while some hemipterists follow this classification (link below), it has by no means been accepted universally.
See the Heteroptera article for the detailed discussion, and a comparison of the two taxoboxes.
Prosorrhyncha is therefore given preference over the other names specifically because the suffixes of the older names are conventionally reserved for taxonomic ranks other than suborder, thus their use would create internal conflict and confusion (e.g., the ending "-oidea" is used for the rank of superfamily, meaning that if "Heteropteroidea" were adopted, it would include, within it, groups such as Pentatomoidea, Lygaeoidea, etc.
