    peer reviewedWe treat the Australian spider wasp ‘Ctenocerini’, revising the systematics of Maurillus Smith, adding a new species Maurillus argenticapitis Pitts & Shimizu sp. nov. and describing two new monobasic genera Maurilloides Pitts & Shimizu gen. nov. based on Maurilloides nigrisoma Pitts & Shimizu sp. nov. and Evansiclavelia Pitts, Rodriguez & Shimizu gen. nov. based on Evansiclavelia poecilopteryx Pitts, Rodriguez & Shimizu sp. nov. We further discuss the phylogenetic position of Maurillus and the convergent evolution of the modification in head and pronotal structures occurring in the above three genera, as well as in pompilids from other subfamilies, that parasitise trapdoor spiders
