The Methocha (Hymenoptera: Thynnidae: Methochinae) of Hong Kong (China), a preliminary faunal list with descriptions of five new species and sexual associations rendered through molecular analysis

Key Points

• To document and describe new species of Methocha identified in Hong Kong, including their sexual associations.
• Described five new Methocha species based on molecular analysis and morphological traits.
• Utilized both female-only and male-only specimens for species identification.
• Provided a phylogenetic tree and key to species for identification.
• Identified two new species based solely on female specimens and two based solely on males.
• Described one species with both male and female specimens linked through molecular analysis.
• Presented a key for species identification and a phylogenetic tree reflecting relationships among species.
