Nannochorista edwardsi Kimmins, 1929
Diagnosis: Tergite XI of the male genitalia reaches the end of the basistyles; the central depression between basistyles on the dorsal surface is shallow and U-shaped; projection from the inner base of the dististyles is short and broad. Forewing length: 6.2 – 9.2 mm.
Distribution – Geographical: ARGENTINA (Neuquén; Rio Negro) and CHILE (Arauco; Aysen; Chiloe; Osorno).
Distribution – Temporal: 16 October until mid-March at 250 – 1360 m elevation.
Ecology: Nothing is known of habitat preferences.
Biology: Nothing is known of immature stages or life history of this species.
Notes: This species may have dark gray maculations adjacent to distal forewing crossveins. However, this characteristic is variable and unreliable for species identification (Byers, 1989). Consequently, male genitalia provide the only consistently reliable characteristics for identification.
