Comostola enodata sp. n.
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
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.
