Abstract
Five new species of Methocha Latreille, 1804 are described from Hong Kong: two species based on females only, Methocha haaksek Barthélémy & Terayama sp. nov. and Methocha leleji Barthélémy & Terayama sp. nov.; two on males only, M. wilsoni Barthélémy & Terayama sp. nov. and M. zetetes Barthélémy & Terayama sp. nov.; and one with females and males associated through molecular analysis, M. hongkongensis Barthélémy & Terayama sp. nov. A key to species and a phylogenetic tree of Methocha occurring in the Hong Kong SAR are provided.

Keywords: Thynnoidea, morphometrics, Cicindelinae, DNA barcoding, phylogenetic
