Bottom Line: The third instar larvae and the pupae of Platyphileurus felscheanus Ohaus, 1910 (Phileurini), recently synonymized with Surutu jelineki Endrődi, 1975 (Cyclocephalini), are described and illustrated, and some life history information is given.The systematic position of this monotypic genus is reassessed at the tribe level by considering larval and adult morphological characters.Both character sets, being described and illustrated, suggest the placement of Platyphileurus in the tribe Oryctini.

ABSTRACT
The third instar larvae and the pupae of Platyphileurus felscheanus Ohaus, 1910 (Phileurini), recently synonymized with Surutu jelineki Endrődi, 1975 (Cyclocephalini), are described and illustrated, and some life history information is given. The larvae were collected and reared in bromeliads in rain forests of Santa Catarina state in southern Brazil. The systematic position of this monotypic genus is reassessed at the tribe level by considering larval and adult morphological characters. Both character sets, being described and illustrated, suggest the placement of Platyphileurus in the tribe Oryctini.

Photos: C Grinter.

Mentions: Left mandible (Figs 5, 8): Form falcate. Scissorial area with S1 and S2 distant but bridged by flat area forming broad apical blade, separated from S3 by acute scissorial notch. S4 of similar size as S3, blunt, of cylindrical appearance in ventral view, separated from S3 by acute and deep notch. Mandible dorsally with 1 long discal seta in front of labium at level of S3 (arrow). Outer margin convex. Scrobis (SCR) with 1 short, thin seta. Dorsal area adjacent to scrobis with 2 rows of 7 sensorial pits. Dorsal area adjacent to molar crown with 3 setae. Acia (AC) well developed, with brush of apical setae. Brustia (BR) with 12 long setae. Ventral surface with elongate-oval stridulatory area (STA) with about 30 narrowly separated, subparallel ridges. Molar area with a tuft of 8 ventral molar setae(VMS) (setae very close together and difficult to count). Molar lobe (ML) large, forming a dorsoventral ridge, not subdivided. Molar crown with 2 lobes. Postartis (PTA) large, spherical. Ventral process triangular with rounded tip.
