Symmimetis heveli sp. n.
10mm. The wings are mostly dark blackish brown, relatively strongly
marked, the forewing postmedial sharply angled and slightly concave distad and
clearly edged with white over its anterior half. There are two parallel but
irregular white lines at the forewing disc where there is a white fleck in muscosa;
these lines are not seen in cristata or other Indian material where
the fleck occurs. The hindwing postmedial is angled on both surfaces of the
wings, distinguishing it from both Bornean congeners, where it tends to be
curved or just more strongly flexed at that position. Two females with similar
facies to this male and similar genitalia to each other (slides 18921, 18927)
are tentatively associated. The male genitalia have the saccus shorter than in muscosa.
In the aedeagus vesica the distal spines are more numerous and the more
basal, robust one shorter with a more slender, curved companion. These latter
may interact with the more basal, posteriorly (rather than laterally) directed
asymmetry of the sclerotised part of the female bursa that is also more lightly
spined inside than that of muscosa.

Habitat preference. The type locality is montane but there are no
vegetation data for it on the label. The putative female is from dipterocarp
forest at 250m on the lower slopes of the limestone G. Api.
