The helicarionid fauna of southeastern to mid-eastern Queensland is dominated by a group of semislugs with moderately reduced shells belonging to genera  Fastosarion ,  Eungarion ,  Stanisicarion ,  Dimidarion ,  Macularion  and  Hymanarion . We comprehensively revise their systematic classification using comparative morpho-anatomy and mitochondrial phylogenetics, and demonstrate that these genera combined form a well-differentiated and monophyletic radiation. In our mitochondrial phylogeny, this radiation is divided into three main clades that are statistically well supported. One clade is also well defined in terms of diagnostic morpho-anatomical characters, but we could not identify diagnostic characters for the other two clades due to considerable levels of morpho-anatomical variation. We propose accepting only two genera,  Fastosarion  (with junior synonyms  Eungarion ,  Dimidarion , and  Hymanarion ) and  Stanisicarion  (with junior synonym  Macularion ). Both genera represent mutually monophleytic sister taxa that can consistently be distinguished by the presence or absence of a penial verge that is fused to the penial wall and by egg shape. We also synonymise  Fastosarion ameyi  with  F. aquavitae ,  F. schelli  with  F. helenkingae ,  Dimidarion peterbrocki  and  D. slatyeri  with  F. alyssa ,  Stanisicarion virens  with  S. freycineti . Revised species descriptions are presented for  Fastosarion alyssa ,  F. aquavitae ,  F. brazieri ,  F. comerfordae ,  F. griseolus ,  F. hannianus ,  F. helenkingae ,  F. mcdonaldi ,  F. minerva ,  F. paluma ,  F. papillosus ,  F. pustulosus ,  F. superbus, Stanisicarion aquila  and  S. freycineti . Nine new species,  Fastosarion deensis ,  F. ephelis ,  F. insularis ,  F. katatonos ,  F. longimentula ,  F. rowani ,  F. sarina ,  F. tuljun  and  Stanisicarion wolvi  are described, bringing the total number of accepted species to 24.
