Nygmia longitegumen sp.
Nygmia longitegumen (paratype)
17-22mm. The facies of the forewings is a
rich pale brown version of the civitta group type, distinguished by the
absence of white marginal marks and the presence of a black one more or less
centrally. The discal spot is absent. The male genitalia are distinctive, with
the tegumen extended ventrally to overlap the vinculum, the highly setose,
triangular valves with spines at the apical and saccular angles, and a bicornute
juxta. The aedeagus is typical of the civitta group with a immaculate
vesica and a small apical spur.
