Syngonorthus Butler

Type species: subpunctatus Butler.

The genus contains a single species, one of the larger members of the tribe. The male antennae are filiform, ciliate. The colour is reddish fawn, fasciated and speckled with dull rufous brown. The wings have darker fringes and discal spots, with straight antemedial and postmedial fasciae crossing the forewing, and a similar postmedial on the hindwing. The postmedials are reproduced on the paler underside by rows of blackish spots on the veins. The hindwing has the margin angled at M3.

The male genitalia have the coremata large, double. The slender, sinuous dorsal processes of the valves are well separated from the main part of the valve. Each of the latter is closely associated with a furca-like structure that extends to the valve apex, and forms a complex pocket-like structure with its pair adjacent to the vinculum. The aedeagus vesica is convolute but without ornament. The eighth sternite is constricted towards the anterior, bearing lateral apodemes that support weak coremata on each side.

The female genitalia have the bursa with an elongate basal tubular section with a ring of sclerotisation at its junction with the short ductus. The basal section is almost twice as long as the pyriform distal part; the latter contains a signum consisting of an irregular ellipse of sclerotisation with an angled, bifid flange arising from it. The bursa is finely corrugate throughout.

Relationships with the next three genera are discussed in the introductory comments for the tribe and under Auzeodes Warren.
