Helcystogramma perelegans


The perelegans   group

This species group is characterized by the presence of the ocellus ( Figure 4A View Figure 4 ), the antenna not ciliate, the labial palpus and the forewing with metallic lustre, the termen slightly concave below apex, the mesothorax without hair pencil from anepisternum; the eighth tergite concave anteriorly, the uncus long, narrowed mesially, deeply and triangularly concave on anterior margin, the gnathos slender and long, acute apically, the valva dilated distally, its ventral free lobe stout, parallel sided, straight at apex, the vinculum with lobes at right angle with margin distally, sharp apically, the saccus short triangular ( Figure 16C View Figure 16 ), and the aedeagus shorter than valva, club-shaped distally, roundly dilated apically in the male genitalia. The perelegans   group contains H. perelegans ( Omelko et Omelko, 1993)   and H. flavifuscum   sp. nov. in China, occurring in the middle and southern parts of China (Figure 1).


This species group is similar to the hibisci   group. It can be separated from the latter by the presence of the ocellus; the longer uncus deeply and triangularly concave on anterior margin, and the aedeagus shorter than valva, roundly dilated apically.
