Fig. 62 in Notes on the species of Plagiodera CHEVROLAT, 1836 of the Australian, Oceanic and Oriental regions, with a description of P. hiekei n. sp. (Coleoptera, Chrysomelidae)

Fig. 62. Plagiodera spp., distribution area of the studied species. The dotted area represents the track Pliocene-Pleistocene (L. MATILE 1990). □ Group A: P. aerea (Philippines); P. riparia (Sulawesi, Bali, New Guinea, Australia: N.Territory?); P. hiekei n. sp. (New Guinea); P. punctipennis (Philippines). ● Group B: P. chapuisi (New Guinea); P. lownei (Australia); P. nitidipennis (Australia); P. amplipennis (Australia); P. philippinensis (Philippines). * Group C: P. cheni (New Guinea, Bismarck: New Ireland); P. violaceipennis (Solomon, Fiji, Tonga); P. fulvicollis (New Hebrides, New Caledonia?); P. samoana (Samoa). M = male; F = female. Notes: The data of Tonga (P. cheni group) is taken from the catalogue of C.A.M. REID: Chrysomelinae of Australia, New Guinea, New Zealand, Pacific Region and relevant S E Asian Taxa. 1993, unpublished manuscript kindly provided to one of the authors (M.D.). Probably P. violaceipennis and P. fulvicollis are synonyms and P. samoana is only a subspecies of this complex. For more precise findings we need deeper studies based on much more material.
