Chorsia hemicyclopis Hampson comb. n.
Pseudogyrtona hemicyclopis Hampson, 1926, Descr. Gen. Spec. Noctuinae, p. 216.

 

 
Chorsia hemicyclopis ♂


Diagnosis. The forewings are more distinctly marked than in other species in this genus, particularly the dark brown trapezium with whitish edging at the apex of the costa. There is a dark dot and a pale oblique basal streak that runs obliquely from the base of the costa across half the wing towards the tornus. In males, the grey hindwings are bisected longitudinally by a paler wedge.

Taxonomic note. The valves have an oblique longitudinal pleat that separates a costal strip from an extensive saccular portion that extends to a spur at the distal end of the pleat just short of the apex. The aedeagus is short but has a relatively complex vesica that terminates in a robust cornutus.

Geographical range. Borneo, Thailand (VK).

Habitat preference. This is an uncommon species of lowland forest up to 500m, but can also occur in secondary and disturbed forests.
