Discussion. — This species resembles festiva Kieffer in its thoracic, 

 wing, abdominal patterns, and in most aspects of the male genitalia, 

 but differs in its paler color, the whitish ends of the halter knobs, 

 and its larger size. Its known distribution includes only western 

 Thailand and northern Malaya.
