T. (T.) monticola Dufour, 1851

Material : 1 ♂: Gourette, Pyrenées Atlantiques, France, 21.06.1970, leg. G. Tiberghien (EPC) ; 1 ♂: Monte Perdido: collado de Añisclo, 2400m alt., Huesca , 16.06.2003, leg. A. Anichtchenko (AAC) ; 3 ♂: Canfranc: barranco de Izas, 1600m alt., 18.06.2005, leg. A. Anichtchenko (AAC); 1 ♂: Canfranc: cabaña de la vuelta de Iserias, Huesca, 15.06.2003, LEG. A. ANICHTCHENKO (AAC).

Description: SpECIES SIMILAR TO T. geniculata , WITH pRONOTUM WIdEST pOSTMEdIALLY ANd pUNCTUREd SMOOTH ELYTRA. BOTH SpECIES HAVE A WELL SCLEROTIZEd Of RHOMBOId OR ARROWHEAd-SHApEd MANUBRIUM ANd A THIN ANd WEAKLY SCLEROTIZEd fLAGELLUM. THE ENdOpHALLI ARE ALSO SIMILAR, WITH A SHORT ANd SUBCYLINdRICAL BASAL pART, A MORE OR LESS INfLATEd MIddLE pART, ANd GRAdUALLY NARROWEd ApICAL. THEY dIffER IN SHApE Of THE MANUBRIUM, I.E. RHOMBOId IN T. monticola BUT Of ARROWHEAd-SHApEd IN T. geniculata . IN AddITION, THEY ARE dISTINGUISHEd BY THE pRESENCE OR NEAR ABSENCE Of BASAL pROTUBERANCES, RESpECTIVELY. THUS, THE DB, VB ANd B ARE SMALL IN T. geniculata ( fIGS 16–19 View FIGURES 16–19 ), BUT VB IS SMALL WHEREAS DB ANd B ARE ALMOST INdISTINCT IN T. monticola ( fIGS 20A, B View FIGURES 20–21 ).
