Abstract
The Philippine islands are one of the key biodiversity hotspots in the Indo-Pacific area. Knowledge of moss-inhabiting flea beetles (Coleoptera: Chrysomelidae: Alticinae), a diverse and ecologically and morphologically enigmatic group in the Philippines is described.
Six species from the Philippines are recorded, belonging to three genera: Benedictus luzonicus Sprecher-Uebersax et al., 2009 (recorded from the Philippines previously), Ivalia antennata sp. nov., I. caligulata sp. nov. and I. postfasciata (Chen, 1934), comb. nov. (transferred from Chabria Jacoby, 1887), Cangshanaltica mindanaoensis sp. nov., and C. luzonica sp. nov. Cox1 barcode sequences of Ivalia antennata and Cangshanaltica mindanaoensis are presented.
Biogeography and diversity of moss-inhabiting flea beetles in the Philippines are discussed.
