• syn. Cataclysta marginipuncta Turner 1937: 77. TL Australia (Queensland, Cape York) MS syn. n.
• syn. Pycnarmon quintula Meyrick 1938a: 78 TL Indonesia (Java, Djokjakarta).

Spiedel & Mey (1999) comment that the C. angulata group of spp. is misplaced in Cataclysta and belong to the Musotiminae (S.H. Yen in litt.) and merits a genus of its own which will [may] be described by Yen.

As Acentropinae as (Cataclysta) in Globiz & LepIndex.

We treat it in the Musotiminae.

Description

A shiny, pale fulvous brown and white sp. which fades to a pale pink-brown. The FW has a white post median line which is withdrawn basally (loops) towards the median position before reaching the posterior margin.There are three or four white streaks in the post median area Subcostally there are three dark spots at the subapical, antemedian and post basal positions. The shiny pale pink brown HW has a diffuse broad, pale median band and four or five black, sub termal spots. Note the distinctive marginal incision near the HW tornus. Musotima [Ambia] decoralis Snellen, 1900 [1901] although much more brightly coloured has similar general patterning and HW shape and may be related.
