A gall midge that induces thick lenticular galls on leaflets ofPuerariaspecies (Fabaceae) in Japan, mainland China, Taiwan and South Korea is described asPitydiplosis puerariaesp. nov. (Diptera: Cecidomyiidae).Tanaostigmodes puerariae(Hymenoptera: Tanaostigmatidae), described earlier from mainland China as an inducer of the lenticular gall, is regarded to be an inquiline.Pitydiplosis puerariaeis distinguishable from the only known congener, the NearcticPitydiplosis packardi, by the male genitalia with entire aedeagus and with hypoproct that is as long as cerci and bilobed with a U‐shaped emargination. DNA sequencing data indicate the existence of three genetically different intraspecific groups: (i) “YNT‐montanagroup” induces galls onPueraria montanaon the Yaeyama Islands, Japan and in northern Taiwan; (ii) “CT‐montanagroup” onP. montanain central Taiwan; (iii) and “JCK‐lobatagroup” onPueraria lobatain mainland China, South Korea and Japan north of Okinoerabu Island. A possible diversification scenario of the three groups is hypothesized based on DNA sequencing data and geohistorical information. A distribution gap of the gall midge on five islands between Tokunoshima and Ishigaki Islands, Japan was confirmed by intensive field surveys. Ecological traits and adult behavior ofPity. puerariaeare also described. Its possibility as a potential biological control agent againstP. lobataseems counter‐indicated.
