Meligethes (Odonthogethes) wagneri Rebmann, 1956

Examined material. China, SHAANXI, MT. HUA, CA. 950 m A.S.L., 34.506944° 110.076389°, 12.vI.2017, P. AUDISIO, M. LIU & M. HUANg LgT, ON fLOWERINg bUSHES Of Sorbaria arborea C.K. SCHNEID ( ROSACEAE ), 12 ♂, 10 ♀ (NWAU, CAR-MZUR).

Distribution. SE AND CENTRAL CHINA (FUJIAN, ZHEJIANg, TAIWAN, E SHAANXI). THIS SpECIES WAS pREvIOUSLY KNOWN ONLY fROm A SERIES Of SpECImENS COLLECTED IN FUJIAN, ZHEJIANg, AND TAIWAN (REbmANN 1956A; KIREJTSHUK 2005; S.- T. HISAmATSU 2009; AUDISIO et al. 2015). THE NEW DATA fROm E SHAANXI CONSIDERAbLY EXTENDS THE gEOgRApHIC RANgE WESTWARD AND NORTHWARD ( FIg. 6b ).

Host-plants. ALL Of THE AbOvE CITED SpECImENS fROm MT. HUA, SHAANXI, WERE COLLECTED ON fLOWERINg bUSHES Of Sorbaria arborea C.K. SCHNEIDER ( ROSACEAE ; FIg. 4E ), bUT DEfINITIvE LARvAL HOST-pLANTS RELATIONSHIpS CANNOT bE ESTAbLISHED. S.- T. HISAmATSU (2009) REpORTED SEvERAL RECORDS Of THIS SpECIES (UNDER THE SpECIfIC EpITHET Meligethes shirozui S. HISAmATSU, 1965, A SYNONYm Of M. wagneri : AUDISIO et al. 2015) fROm TAIWAN ON fLOWERS Of Viburnum Sp. ( CApRIfOLIACEAE ), Callicarpa formosa ROLfE ( LAmIACEAE ), AND Prunus phaeosticta (HANSEN) MAXIm. ( ROSACEAE ). ONLY THE LATTER pLANT REpRESENTS A pOSSIbLE LARvAL HOST. Meligethes wagneri OCCURS IN bUSHY AREAS, CLOSE TO RIvER EDgES AND vALLEYS, AT INTERmEDIATE ALTITUDES (CA. 1000–2300 m) (REbmANN, 1956A; S.- T. HISAmATSU 2009; AUDISIO et al. 2015; DATA AbOvE).
