Female: Length of wing 0.78 (0.69-0.89, n = 8) mm. 



Head. — Eyes broadly separated, bare. Antenna with flagellar seg- 

 ments in proportion of 15:11:12:14:14:14:14:15:15:16:16:16:25, an- 

 tennal ratio 0.77 (0.71-0.81, n = 5); distal sensory tufts present on 

 segments III, VIII-X. Palpal segments in proportion of 8:17:20:7:10, 

 third segment slightly swollen, 2.1 (1.7-2.4, n-=9) times as long as 

 greatest breadth, with a small, deep sensory pit. Mandible with 15 

 (14-15, n = 6) teeth.

Wing. — Pattern as figured; second radial cell dark; pale spot over 

 r-m crossvein narrow, extending to coastal margin; cell R, with four 

 small, round pale spots, the two poststigmatic spots well separated 

 and located one behind the other, the posterior one located 

 slightly proximad, apices of veins dark at wing margin; three small 

 pale spots in cell Mi; only one pale spot in distal part of cell Mz; a 

 round pale spot in center of cell M4; anal cell with one pale spot in 

 distal portion; cell M2 with a pale spot lying behind medial fork, none 

 in front of mediocubital fork; a pale spot lying just distad of basal 

 arculus. Macrotrichia sparse and in rows on distal half of wing, 

 a few in base of cell M2 and in anal cell; costa extending to 0.59
