Key to adults of Domodon species

1 Tergite 4 largely or entirely black or dark brown ( Figs 1 , 6 , 19 ). Other tergites also partly dark ( Figs 1 , 6 , 19 ). Vertex entirely black or dark brown, with or without metallic hue ( Figs 3 , 7 , 18 )................................................ 2

- Tergites entirely yellowish brown, although differences in length, arrangement and colour of the pile create the impression of a pattern of vaguely delimited dark median and lateral maculae on the tergites ( Fig. 10 ). Vertex largely yellowish brown with some small dark brown markings ( Figs 12–14 )............................................. D. inaculeatus sp. nov.

2 Antenna with basoflagellomere approximately as long as scape ( Fig. 4 ). Tergite 3 partly yellowish, at least along posterior margin ( Figs 1 , 24, 27 )................................................................................. 3

- Antenna with basoflagellomere more than three times as long as scape ( Fig. 17 ). Tergite 3 entirely blackish ( Figs 19 , 26 )....................................................................................... D. sensibilis sp. nov.

3 Face pale yellow without black vitta. Femora brownish with pale yellow tip............... D. peperpotensis Reemer, 2014

- Face pale yellow with brown median vitta ( Figs 3 , 7 ). Femora entirely brownish, without yellow marks................. 4

4 Yellow markings along posterior margin of tergite confined to posterior half of tergite ( Figs 1 , 24 ). Surstylus dorsally with a row of short pointed setae ( Fig. 20 )....................................................... D. caxiuana sp. nov.

- Yellow markings along posterior margin of tergite 3 medially connected with yellow markings along anterior margin of tergite ( Fig. 27 ). Surstylus dorsally without a row of short pointed setae ( Fig. 23 ).................... D. zodiacus Reemer, 2013
