Further taxonomic differentiation in thequadrispinosa complex of Dicraspeda Chaudoirin the Papuan Region and additional records ofthe genus (Coleoptera: Carabidae: Odacanthinae)

摘要

The Papuan and southern Oriental odacanthine species Dicraspeda quadrispinosaChaudoir is further subdivided into additional taxa which provisionally aredescribed as new subspecies: Dicraspeda quadrispinosa krikkeni from San CristobalIsland, D. quadrispinosa vanasseni from Guadalcanal Island, D. quadrispinosabrachyspinosa from the minute Kolombangara Island, all Solomon Archipelago,and D. quadrispinosa ambonensis from Ambon Island in the Buru Archipelago.A new key is given for all described taxa of Dicraspeda quadrispinosa. In particularthe Solomon Archipelago seems to be the home of a number of well differentiatedtaxa that exhibit divergent character evolution and are restricted to single islands.New records of some additional little known species of the genus DicraspedaChaudoir are communicated which considerably extend their presently recordedranges.
