Taxonomic history
The was established by Takeuchi in 1938. Several have been described from East Asia by Shinohara (1999, 2006, 2016), with some species known only from female specimens until recent descriptions of associated males.
Molecular identification
COI mitochondrial barcodes have been successfully applied to identify and match unassociated male specimens to described , particularly useful given the morphological similarity between species and incomplete descriptions.
