Comostola enodata sp. n.  

Comostola enodata

8-9mm. This species is very similar in external appearance to chlorargyra and allies, but tends to have more regular marginal beading as mentioned above. There is some asymmetry in the male genitalia but the valves lack the distal fans of setae seen in the chlorargyra group. The sacculus of the right valve terminates in a triangular process and lacks the tongue-like central lobe of chlorargyra. The socii are broader basally. The eighth sternite has three, rather than four, shallow lobes at the margin. Given the uncertainty in the literature over the identity of this and the previous species (e.g. Prout, 1934, Gross-Schmett. Erde 12: 131), a holotype only is listed, and the distribution based on dissected material alone.

Holotype  BRUNEI: 3m, Seria, secondary and coastal veg., 30.12.78 (Lt. Col. M.G. Allen) BM geometrid slide 16859.

Geographical range. Borneo, Sumatra, Singapore (H.N. Ridley material), Sulawesi, New Guinea.

Habitat preference. The species is infrequent in the lowlands, perhaps favouring more disturbed forest types including coastal and heath forest.
