Amblyterus cicatricosus (Gyllenhal, 1817)

Melolontha cicatricosa Gyllenhal, 1817 (in Schönherr 1817: 113)

Amblyterus geminatus MacLeay, 1819: 142 ; Blanchard 1851: 224 (synonymy)

Types. Melolontha cicatricosa Gyllenhal, 1817 : lectotype (present designation): ϐ: “N. Holland / D. Hooker // Typus // Melolontha / cicatricosa Gyll. // NHRS-JLKB / 000029815” (NHRS).

Remarks. A lectotype is designated here for Melolontha cicatricosa ( Fig. 6 A–F) to fix the species identity. Carne (1958) examined the lectotype in NHRS. The synonymy of A. geminatus with A. cicatricosus was first proposed by Blanchard (1851). MacLeay’s holotype of A. geminatus is in ANIC although it was not listed when all type material was removed from the Macleay Museum, Sydney University ( Britton & Stanbury 1981). It was examined by Carne (1958) and re-examined by us and the synonymy is hereby confirmed.

Amblyterus cicatricosus occurs from central New South Wales to central Queensland and is a common species around Sydney ( AMS). It is distinguished from congeners by its size, colour, leg structure, and large male maxillary palpi ( Carne 1958) .
