Abstract


The genus Cycadophila Xu, Tang & Skelley (Coleoptera: Erotylidae: Pharaxonothinae) associated with Cycas L. (Cycadacaeae) in Asia is reviewed. Strobilophila, new subgenus, with five species is described: Cycadophila (Strobilophila) assamensis new species, C. (S.) hiepi new species, C. (S.) kwaiensis new species, C. (S.) tansachai new species and C. (S.) yangi new species, all associated with Cycas. For the nominate subgenus Cycadophila eight new species are described, Cycadophila (Cycadophila) abyssa new species, C. (C.) collina new species,C. (C.) samara new species, C. (C.) convexa new species, C. (C.) cyclochasma new species, C. (C.) eurynota new species, C. (C.) papua new species, and C. (C.) torquata new species and four new generic combinations are proposed: C. (C.) vittata (Arrow) new combination, C. (C.) discimaculata (Mader) new combination, C. (C.) intermedia (Chûjô) new combination, and C. (C.) lata (Grouvelle) new combination. Only the first three listed species of the nominate subgenus have known associations with Cycas. Species are distinguished on the basis of morphology and/or by analysis of 16S rRNA gene sequences. The larva of subgenus Strobilophila is described based on individuals collected together with adults and matched with analysis of 16S rRNA gene sequences. Keys to subgenera and species of known adults and larvae are provided.
