Burmacrocera new genus (Mycetophilidae). 

 Closely allied to Macrocera, with which the venation nearly agrees, 

 but there is no cross-vein between subcosta and radius, Cu2 is not 

 bent, the subcosta is longer, and the anal fails before the margin. 

 Second antennal joint cylindrical, not globose; antennas 16-jointed, 

 very slender, but not nearly so long as the wings. Legs very long and

 small, claws minute. Thorax with coarse bristles; abdomen slender, 

 petiolate basally; eyes (male) extremely large, covering most of head, 

 the facets elevated, low-conical. Type the following.
