Abstract
The monotypic genus Enigmadiplosis Harris (Diptera: Cecidomyiidae) was placed in the tribe Clinodiplosini based on adult morphology, but the genus is somewhat puzzling because larvae are typical for the tribe Cecidomyiini. In this study, we describe Enigmadiplosis harrisi sp. nov., a pest species that damages young leaves of the ornamental shrub Rhododendron pulchrum in Mie Prefecture, Honshu, Japan. We also conducted a molecular phylogenetic analysis to confirm the tribal placement. The result clearly indicates that Enigmadiplosis belongs to Cecidomyiini and we therefore assign the genus to that tribe. In addition, we redescribe Clinodiplosis rhododendri (Felt) that forms leaf-roll galls on Rhododendron spp. in eastern North America to allay future questions as to the identity and show that this is unrelated to the new Japanese species.
期刊介绍：
Invertebrate Systematics (formerly known as Invertebrate Taxonomy) is an international journal publishing original and significant contributions on the systematics, phylogeny and biogeography of all invertebrate taxa. Articles in the journal provide comprehensive treatments of clearly defined taxonomic groups, often emphasising their biodiversity patterns and/or biological aspects. The journal also includes contributions on the systematics of selected species that are of particular conservation, economic, medical or veterinary importance.
Invertebrate Systematics is a vital resource globally for scientists, students, conservation biologists, environmental consultants and government policy advisors who are interested in terrestrial, freshwater and marine systems.
Invertebrate Systematics is published with the endorsement of the Commonwealth Scientific and Industrial Research Organisation (CSIRO) and the Australian Academy of Science.
