Synchalara minax is a moth in the Xyloryctidae family. It was described by Edward Meyrick in 1907. It is found in India (Assam).
The wingspan is 22-25 mm. The forewings are whitish-ochreous tinged with brownish and irrorated with fuscous. The basal fourth of the costa suffused with dark fuscous. There is a very indistinct irregular line of fuscous suffusion from the costa at one-fourth to the dorsum before the middle. There is a broad oblique fascia of dark fuscous suffusion, sharply defined and pale-edged anteriorly, very undefined posteriorly, from the costa about the middle, reaching more than half across the wing. A suffused fuscous curved line is found from the costa about three-fourths, almost obsolete on the dorsal half. There is also a marginal row of blackish dots around the apex and termen. The hindwings are pale grey.
