Chorsia
greenleavesi sp. n.
 10mm,  11mm. The facies is similar to that of colyeri
but
the forewing ground is more of a lightly variegated white and grey, and the
three triangles are not so prominent. In the male genitalia both dorsal and
distal processes of the uncus are narrow, the former curved and slightly
clubbed, the latter straight except at the acute, downcurved apex. The two parts
diverge from a much shorter ‘stalk’ than in kingi. The valves and vinculum are
similar to those of colyeri except the apical portion of the former is less
tapering, more rounded. The aedeagus vesica is less globular and with more
distinct diverticula.
