Ectrepesthoneura Enderlein, 1911

Willistoniella Meunier, 1904: 74 (preoccupied by Mik, 1895).

Meunieria Johannsen, 1909: 87 (preoccupied by Kieffer, 1904).

Ectrepesthoneura Enderlein, 1911: 115 .

DIAGNOSIS: As given by Chandler (1980): Lateral ocelli remote from eye margin; laterotergites bare; Sc ending in R before base of RS; R 4 present; R 1 short, at most twice as long as r­m; R 5 straight; C prolonged well beyond tip of R 5; veins of medial and cubital sectors weak and faint; posterior fork sessile. Males with ‘‘sensory pit’’ near the base of mid tibia; hind tibial comb absent.

TYPE SPECIES: Tetragoneura hirta Winnertz, 1846: 19 (orig. designation)

COMMENTS: There are about 10 extant species from the Holarctic region. The genus is very close to Tetragoneura Winnertz (about 100 widespread living species) and is sometimes included in it or treated within the tribe Gnoristini ( Tuomikoski, 1966; Vaisanen, 1986). There are two fossil species described from Baltic amber ( Meunier, 1904) and the Oligocene of Rott, Germany ( Statz, 1944). Chandler (1999) suggested that Ectrepesthoneura was paraphyletic.
