Type species. Lepidiota laevis Arrow, 1932 .

Included species. Barryfilius centralis ( Britton, 1978) , Barryfilius contiguous ( Britton, 1978) , Barryfilius laevis ( Arrow, 1932) , Barryfilius lewisae ( Britton, 1978) , Barryfilius quinarius ( Britton, 1978) , Barryfilius vernus ( Britton, 1978) .

Description. Body 17–26 mm long; colouring not metallic. Mandibles not curved downwards at apices. Labrum not strongly projecting, not deflexed and not extended in the same plane as the clypeus, not or only slightly excavated anteriorly. Antennae with 10 antennomeres, male antennal club with 3–6 full-length lamellae but with some development on other antennomeres, males with club at least as long as remaining antennomeres combined. Anterior face of clypeus shallow, ratio of greatest width to mid depth> 6.6; upper surface of clypeus slightly concave. Clypeofrontal suture not raised or angulate. Pronotum with long, erect yellow-brown setae only on anterior and posterior margins; posterior pronotal angles obvious; pronotal hypomera with elongate white, flattened setae and long, yellow setae. Elytra with a few long setae close to the base, otherwise punctures with minute, stout, yellow-brown or white setae. Ventral thorax with long, yellow setae, no scales. Anterior faces of prefemur and protibia with yellow setae and flattened, adpressed, white setae. Pretarsal claws with a tooth, prominent and near middle. Anterior edge of metafemur not concave near base. Apical spurs of metatibia inserted close together so that the metatarsus moves above the spurs. Aedeagus with parameres symmetrical or near to symmetrical.

Diagnosis. Differs from other genera of Australian Melolonthini (sensu Britton 1978) by the following combination of characters: body 17–26 mm long; labrum not or only slightly excavated anteriorly; anterior face of clypeus shallow, ratio of greatest width to mid depth> 6.6; upper surface of clypeus slightly concave; clypeofrontal suture not raised or angulate; antennae with 10 antennomeres, male antennal club with 3–6 full-length lamellae but with some development on other antennomeres, males with club at least as long as remaining antennomeres; pronotum with long, erect yellow-brown setae only on anterior and posterior margins; posterior pronotal angles obvious; pronotal hypomera with elongate white, flattened setae and long, yellow setae; elytra with a few long setae close to the base, otherwise punctures with minute, stout, yellow-brown or white setae; anterior faces of prefemora and protibiae with yellow setae and at least a few broad or elongate, flattened, adpressed, white setae; tooth on pretarsal claws prominent and near base; anterior edge of metafemur not concave near base; aedeagus with parameres symmetrical or near to symmetrical.

Etymology. The genus is named for Dr Rachael Barry and her child, my grandson, Flint Barry Allsopp . It combines Rachael’s family name with filius, Latin for son. The genus name is masculine in gender.
