Key to males of Caledomina

1. In genitalia, sternite IX without sternal process ( Fig. 6 ); dorsal branch of superior appendage oriented dorsally ( Fig. 6 ); ventral branch of superior appendage drop-shaped ( Fig. 6 ) ................................... ......................................................................................................................... C. dorsospina sp. nov.

– In genitalia, sternite IX with long sternal process ( Figs 1 , 11 ); dorsal branch of superior appendage oriented posteriorly ( Figs 1 , 11 ); ventral branch of superior appendage parallel-sided ( Fig. 11 ) or tapering ( Fig. 1 ) ................................................................................................................................ 2

2. In genitalia, tergite IX weakly produced dorsally ( C. noumea in Fig. 19 ); dorsal branch of superior appendage apically curving ventrally and with ventrally oriented spines .......................................... .................................................................................................................. C. noumea Johanson, 2011

– In genitalia, tergite IX strongly produced dorsally ( Figs 1 , 11 ); dorsal branch of superior appendage apically oriented posteriorly and with ventrally or mesally oriented spines .................................... 3

3. In genitalia, sternite IX with sternal process exceeding inferior appendage posteriorly ( Fig. 11 ); dorsal branch of superior appendage with mesally oriented spines ( Fig. 12 ) .................................... ............................................................................................................................. C. kohensis sp. nov.

– In genitalia, sternite IX with sternal process shorter than inferior appendage ( Fig. 1 ); dorsal branch of superior appendage with mesally and ventrally oriented spines ( Figs 1–2 ) ................................... ............................................................................................................................
