-{'''Pancrustacea'''}- je [[Kladus|klada]], koja obuhvata sve [[rakovi|rakove]] i [[Hexapoda|heksapode]].{{r|Zrzavý1997}} Ovo grupiranje je kontrarno hipotezi -{[[Atelocerata]]}-, po kojoj su -{[[Myriapoda]]}- i -{[[Hexapoda]]}- are [[Sestrinske vrste|sistrinski taksoni]], a [[rakovi]] su samo u manjoj meri srodni. Od 2010. godine, -{Pancrustacea}- takson je široko prihvaćen.{{r|Rota-Stabelli2010}} Ovaj kladus se isto tako naziva -{'''Tetraconata'''}-, u smislu četvrtastih -{[[ommatidia]]}- koje mnogi članovi poseduju.{{r|Dohle2001}} To ime neki naučnici preferiraju kao način izbegavanja zabune jer se prefiks -{„pan-”}- koristi kao indikacija da klada obuhvata [[krunska grupa|krunsku grupu]] i sve pretstavnike matičnih grupa.{{r|Richter2009}}
