Key to the Embolemidae of Japan

Females (unknown in the species not present in the key to the females)

1. Head + mesosoma fusiform ( Figs 6 C, 7); tarsi very slender ( Fig. 7 ); eye strongly reduced ( Fig. 6 A); scutellum very long and narrow, alutaceous, trapezoidal, with shorter base posterior ( Figs 6 B, C); metanotum reduced to very narrow longitudinal carina forming a bridge upon the first region of propodeum ( Figs 6 B, C)................................................................................................. Trogloembolemus fujiei Olmi, Mita et Guglielmino , sp. nov. 1

- Head + mesosoma not fusiform (as in Fig. 8 ); tarsi normal as in ( Fig. 8 ); eye normal ( Figs 2 A, 3A, 4A, 5A); scutellum subcircular ( Figs 2 B, 3B, 4B, 5B); metanotum short and transverse ( Figs 2 B, 3B, 4B, 5B)............................... 2 1. Trogloembolemus fujiei is a very characteristic species with antennae longer than head + mesosoma + metasoma and antennal segment 3 more than 3 × as long as segment 2. These characters are not present apparently in the other three above species. However, we have not included these characters in the above key, because Hilpert (1989) has shown that in Embolemus ruddii Westwood, 1833 , they are variable. We cannot exclude that the same variability can be present also in T. fujiei .

2. Dorsal anterior surface of propodeum shiny, smooth, weakly granulated, not rugose ( Fig. 2 B).............................................................................. Embolemus honshuensis Olmi, Mita et Guglielmino , sp. nov.

- Dorsal anterior surface of propodeum dull, rugose ( Figs 3 B, 4B)................................................3

3. Dorsal surface of propodeum with median depression situated at border between anterior and posterior surface ( Fig. 4 C)................................................................................. Embolemus walkeri Richards

- Dorsal surface of propodeum without median depression situated at border between anterior and posterior surface ( Fig. 3 C)................................................................................ Embolemus krombeini Olmi
