A new melanistic species of Megacampsomeris Betrem, 1928 from the Philippines and taxonomic reassessment of Laevicampsomeris luzonensis (Rohwer, 1921) (Hymenoptera, Scoliidae, Campsomerini)

A new species of Megacampsomeris Betrem, 1928 (Hymenoptera, Scoliidae, Campsomerini) from Mindanao in the Philippines, Megacampsomeris funesta Castagnet & Cabon, sp. nov., is described and illustrated on the basis of both sexes. This new species, entirely melanistic with brown pilosity, is similar in habitus to M. habrocoma (Smith, 1855), M. laevivertex Betrem, 1928, and M. malaccensis Betrem, 1928 from Indonesia but differs mainly in its finer, denser and often coalescent punctation.

In addition, the examination of multiple Laevicampsomeris luzonensis (Rohwer, 1921) specimens, including male genitalia, supports its reallocation to the genus Megacampsomeris. Thus the new combination is proposed: Megacampsomeris luzonensis (Rohwer, 1921), comb. nov. Finally, M. asiatica (de Saussure, 1858) and M. prismatica (Smith, 1855) are removed from the Philippines fauna.

A determination key and an updated list of Megacampsomeris species from the Philippines are given.
