Superlestes, new genus 



Runs out in Munz's key to Lestes. From Lestes and Austro- 

 lestes it is separated at once by the shortening of M3 which in the 

 front wing reaches the wing margin at about the level of the proxi- 

 mal side of the stigma and in the hind wing proximal to this level. 

 In the other genera M3 reaches the wing margin in both wings 

 under the stigma or even distal to it. Superlestes differs from 

 Lestes sponsa, type of the genus, and Austrolestes in having Cu, 

 and CU2 arise from the medio-anal link in very close proximity, 

 Cui curved forward from this point, and the first postquadrangu- 

 lar cell with the anterior and proximal sides about equal, and the 

 distal and posterior sides about equal, in which character Super- 

 lestes resembles Lestes virgatus and L. viridis. In Lestes sponsa 

 and Austrolestes Cui and Cu2 are more separated at the medio- 

 anal link, Cux is straight, and the first postquadrangular cell has 

 the anterior side longer than the proximal, and the posterior 

 longer than the distal. Other venational characters of Superlestes 

 are: M2 arising in the front wing between the fourth and fifth 

 postnodals, and in the hind wing at or near the fourth; Mia 

 zigzag, arising at the sixth to eighth postnodals in the front wing 

 and at about the sixth in the hind wing; bridge vein of Rg^a rising 

 from Mi+j well distad to the forking of Mj+j and M3; three 

 sectors between M, and Mj, two between Mj and Rs, two between 

 Rs and Mj, and two between M3 and M^; 16-17 postnodals in the 

 front wing and 14-16 in the hind wing; stigma covering three cells.
