Comments. In two females, one from Parque Nacional Conguillío, Cautín ( Figs 26–29 ) and one from Volcán Villarrica, Cautín ( Fig. 31 ), only the last flagellomere is black, while the rest of the antenna is orange yellowish. The male from Temuco, Malleco ( Figs 23–25 ) and the other two females from Las Trancas, Ñuble ( Figs 30, 33–34 ) match the pattern of the color of the antenna of the holotype ( Fig. 21 ).
