Cypa pallens brooksi Clark; Diehl, 1980: 28

Diagnosis

See Cypa decolor Walker. Some specimens have greyish forewings, rather than greenish brown ones (e.g. as illustrated by Diehl (1980)); these may be faded.

Taxonomic Notes

1. The male genitalia of brooksi illustrated by Jordan (1931:242) are very similar to those of terranea from Borneo: the setose process on the valve is slightly larger and the spines on the aedeagus apex are less developed than in Bornean specimens. Nevertheless the taxa are undoubtedly conspecific. Diehl (1980) subordinated duponti to brooksi.
2. The Cypa species terranea Butler, duponti Roepke and uniformis Mell all have straight fasciation on the hindwing underside as indicated for terranea in Part 3, but the material to hand then covered under that species was mixed. Plate 15 in Part 3 correctly illustrates terranea, but the genitalia in fig 152 were from a specimen of duponti, a somewhat paler species. The situation was clarified by Kitching & Cadiou (2000), who retained the taxon brooksi Clark as a synonym of terranea. C. terranea is rarer than duponti in Borneo (see next Note), and is only known in Borneo from two specimens from disturbed lowland localities.

Geographical range

Sundaland.

Habitat preference

This is probably a rare lowland species but the specimen taken on the Mulu survey was from lower montane forest on limestone.
