Thailand Agromyzidae (Diptera)-2

Area of Science:

• Entomology
• Biodiversity Research
• Insect Taxonomy

Background:

• The Agromyzinae subfamily, commonly known as leaf-miner flies, represents a significant group of insects with diverse ecological roles.
• A comprehensive understanding of Agromyzinae diversity in Thailand is crucial for biodiversity assessments and pest management strategies.

Purpose of the Study:

• To conduct a systematic revision of the Agromyzinae subfamily in Thailand.
• To identify and describe new species and document species new to the Thai fauna.
• To provide taxonomic keys for identification.

Main Methods:

• Revisionary taxonomic study of Agromyzinae specimens collected in Thailand.
• Morphological examination and comparison with existing type specimens and literature.
• Description of new species and recording of new distributional data.
• Establishment of new synonymy based on comparative analysis.

Main Results:

• A total of 29 Agromyzinae species found in Thailand were revised.
• Thirteen new species are described: Melanagromyza ancyla sp. nov., M. catalexis sp. nov., M. cirrappendicula sp. nov., M. lunulata sp. nov., M. macilenta sp. nov., M. multistriata sp. nov., M. pandiculata sp. nov., M. sexseriata sp. nov., M. spinuliloba sp. nov., M. turgida sp. nov., Ophiomyia flagellata sp. nov., O. quadrifida sp. nov., and O. striata sp. nov.
• Nine species, including three Agromyza, two Melanagromyza, and four Ophiomyia, are recorded as new to Thailand.
• Melanagromyza cordiophoeta Spencer, 1961, is established as a junior synonym of M. dolichostigma Meijere, 1922.
• Taxonomic keys for the genera Agromyza, Melanagromyza, and Ophiomyia in Thailand are provided.

Conclusions:

• The revision significantly expands the known diversity of Agromyzinae in Thailand.
• The study provides essential taxonomic tools for future research and identification of these leaf-miner flies.
• This work contributes to the broader understanding of insect biodiversity in Southeast Asia.
