T. (T.) intermedia Herrich-Schäffer, 1831

THIS SpECIES IS CHARACTERIZEd BY THE pRONOTUM SLIGHTLY NARROWEd BEfORE THE BASAL ANGLES BUT WITH MARGINAL RIdGE ENTIRE, MESOSTERNUM STRONGLY fORKEd, ANd ELYTRA dULL BLACK WITH SCATTEREd SHALLOW pUNCTATION. BOdY RATHER LARGE ANd BROAd, 12–16 MM. WHILE MOST Timarcha s. str. SpECIES fEEd ON RUBIACEAE ANd/OR PLANTAGINACEAE , THE fOOd-pLANTS Of THE SpECIES IN THIS GROUp ARE ALWAYS BRASSICACEAE ( JOLIVET & PETITpIERRE 1973; PETITpIERRE & DACCORdI 2013). ITS CHOROLOGY COVERS SOUTHEASTERN IBERIA, T. intermedia S. STR. IS GENERALLY fOUNd AT LOW ALTITUdES IN ALICANTE, MURCIA ANd ALMERíA pROVINCES, WHEREAS T. intermedia carmelenae PETITpIERRE, 2013 stat. nov., T. intermedia kiesenwetteri KRAATZ, 1879 stat. nov., ANd T. intermedia lugens ROSENHAUER, 1856 stat. nov., INHABIT SOME Of THE ISOLATEd HIGH MOUNTAINS IN THE GRANAdA OR JAÉN pROVINCES, GENERALLY OVER 1500 M ALTITUdE. ENdOpHALLI SHOWING A GLOBULAR ApICAL pART WITH A HORN-LIKE ApICAL pROTUBERANCE A, BASAL pART fINE ANd CYLINdRICAL WITH SMALL B ANd ALMOST INdISTINCT VB ANd DB pROTUBERANCES ( fIGS 4–7 ). THE fOUR SUBSpECIES dISpLAY THE SAME TYpE Of INTERNAL SAC, THEREfORE WE pROpOSE THE pREVIOUSLY qUOTEd stat. nov.
