Homoneura ( Homoneura) bistriata group

Diagnosis. Palpus yellow except for black tip. Wing with a brown medial spot present between r-m and apical spot on R4+5 ( Fig. 17 ), brown preapical or apical spot on R2+3 confluent or isolated with medial spot on R4+5; brown apical spot on R4+5 and M1 confluent or isolated; brown cloud or stripe-like spot on r-m and dm-cu; a distinctive brown apical spot at tip of Sc and R1, confluent or separated from brown spot on r-m. Abdomen yellow to yellowish brown, male tergites 3–6 or 5–6 each with a brown medial spot or stripe; hypandrium H-shaped, surstylus with a ventral process, originated from ventroapical corner of epandrium; postgonite shorter than aedeagus (except for the only female known in the H. ( H.) hainanensis and H. ( H.) extensa ).

This group is similar to the H. ( H.) singularis group, but in H. ( H.) singularis group, wing has two brown spots between r-m and apical spot on R4+5. It is also similar to the H. ( H.) striatifrons group, but in H. ( H.) striatifrons group, wing has larger brown spots and a small brown spot is present on the crossed base of R2+3 and R4+5.
