T. (T.) calceata Pérez Arcas, 1865

Material: 2 ♂: Galapagar , Madrid, 12.02.1989, leg. A. Anichtchenko (AAC) ; 1 ♂: San Sebastián de los Reyes , Madrid, 18.10.1997, leg. A. Anichtchenko (AAC) ; 1 ♂: Uclés, Tarancón, Cuenca, 29.03.2006, leg. A. Anichtchenko (AAC); 3 ♂: Navahermosa, Toledo, 27.02.2007, leg. A. Anichtchenko (AAC).

Description: THE ENdOpHALLUS STRUCTURE ( fIGS 13A, B ), IS VERY SIMILAR TO THOSE Of THE “ T. goettingensis ”—GROUp, BUT IT dIffERS fROM ALL THE SpECIES KNOWN SO fAR fOR THIS CHARACTER BY THEIR ASYMMETRIC DA pROTUBERANCES, NAMELY A HYpERTROpHIC LEfT ANd A REdUCEd RIGHT pROTUBERANCE. THE BASAL pART Of ENdOpHALLUS IS SpHAERICAL, dORSALLY WITH

MERGEd DB pROTUBERANCES, ANd WITH CLEARLY VISIBLE VB. THE fLAGELLUM IS WEAKLY SCLEROTIZEd CONTRARY TO THE MANUBRIUM, WHICH IS LONG, NARROW ANd WITH pARALLEL SIdES.
