“Nola” sijthoffi van Eecke
van Eecke, 1920, Zool. Meded. Leiden, 5: 119.
van Eecke, 1926, Zool. Meded. Leiden, 9: 48.
Diagnosis. The forewing is rather dirty white with grey tinges, and the
hindwing is pale grey. The forewing has a prominent blackish triangle medially
on the costa and smaller black marks subbasally and postmedially. A curved,
finely punctate postmedial extends posteriorly from the latter. The male
antennae are bipectinate.
Taxonomic note. The male genitalia have a strong uncus but no scaphial
structures. The valves, though somewhat cleft, are not typically of Nola,
the sacculus being ventrally expanded around the harpe and with an unusual tuft
of inwardly directed scales distally on it. The male genitalia are the same in
both races, the typical race having more heavily marked forewings with the
distal margin broadly shaded at the tornus and with irregular markings extending
to the dorsum from the medial triangle. However, the Sumatran taxon N.
Roepke has very similar facies and may be conspecific also. In which case two
taxa may be involved, sympatric in Sumatra. The male genitalia (but not the
Inoue from Japan are somewhat similar in valve shape.
Geographical range. Java; Sumatra, Borneo (ssp. sumatrana).
Habitat preference. Single specimens have been taken in the lower montane
forest zone of G. Mulu (1000m) and on the limestone G. Api (900m).
