Holotype male, NIGP167158. This specimen is mostly wizened, especially the abdomen dorsally, details of which are scarcely visible. Consequently, the separation of tergum 10 might be a result of the decay, or may be considered an autapomorphy of this new genus. In addition, most parts of hind wings are overlapped under forewings, therefore not completely visible, but the apical veins are clear.
