Ulopsina, a remarkable new ulopine leafhopper genus from China

Area of Science:

• Entomology
• Taxonomy
• Insect Systematics

Background:

• The subfamily Ulopinae is a diverse group of leafhoppers with complex tribal classifications.
• Existing tribal delimitations within Ulopinae, specifically Mesargini and Coloborrhinini, may not represent natural evolutionary groupings.

Purpose of the Study:

• To describe a new cicadellid genus, Ulopsina gen. nov., and two new species, U. sinica sp. nov. and U. szwedoi sp. nov., from China.
• To investigate the taxonomic placement of the new genus and its implications for the classification of the subfamily Ulopinae.
• To provide a checklist of Ulopinae species in China and reassign species previously placed in the genus Moonia.

Main Methods:

• Morphological description and illustration of the new genus and species.
• Comparative analysis of morphological characters to assess tribal relationships.
• Taxonomic revision involving the transfer of nine species from Moonia to Mesargus.

Main Results:

• Description of Ulopsina gen. nov., U. sinica sp. nov., and U. szwedoi sp. nov.
• Identification of morphological characters in Ulopsina that bridge the gap between the tribes Mesargini and Coloborrhinini.
• Uncertainty regarding the precise tribal placement of Ulopsina, suggesting potential issues with current tribal definitions.
• Compilation of a checklist of Chinese Ulopinae.
• Reclassification of nine Chinese Moonia species into the genus Mesargus (comb. nov.).

Conclusions:

• The discovery of Ulopsina gen. nov. suggests that the current tribal classification of Ulopinae may not be natural.
• Further research is needed to clarify the phylogenetic relationships within the Ulopinae subfamily.
• The taxonomic revision provides a more accurate classification of Chinese Ulopinae species.
