Key to the species of the genus Anasta Emeljanov

1. Forewings with M vein first bifurcated to M1+2 and M3+4 veins distinctly beyond bifurcation of CuA, nearly abreast with Sc+R ( Fig. 3 B)......................................................................... A. lobosa sp. nov.

- Forewings with M vein first bifurcated to M1+2 and M3+4 veins near bifurcation of CuA, distinctly ahead of Sc+R ( Fig. 3 A, C, D)............................................................................................... 2

2. Cephalic process distinctly short, vertex with the ratio of length in central line to width in base (1.65–1.72):1 ( Fig. 4A )............................................................................ A. australiaca (Lallemand) comb. nov.

- Cephalic process long, vertex with the ratio of length in central line to width in base more than 2:1..................... 3

3. Vertex with the ratio of length in central line to width in base (2.03–2.66):1........................................ 4

- Vertex with the ratio of length in central line to width in base more than 3:1....................................... 5

4. Cephalic process distinctly long, nearly equally wide before and after contraction of vertex; aedeagus with ventrolateral lobes large and long ( Fig. 10A ).............................................................. A. prognatha (Distant)

- Cephalic process relatively short, narrower after contraction of vertex; aedeagus with ventrolateral lobes distinctly short and small ( Fig. 13A )............................................................. A. vitiensis Emeljanov & Wilson

5. Cephalic process distinctly long; vertex with media carina long and prominent.......... A. minuta (Lallemand) comb. nov.

- Cephalic process relatively short; vertex with media carina short and weak..................... A. timorina (Lallemand)
