Diagnosis

The male is smaller than the female, and the suprahumerals are obtuse and not easily seen from the front. The metopidium is perpendicular, and is continued in a slight curve over the dorsum as a posterior horn, reaching to the tegmina. General colour dark fuscous, with a pale ochreous spot above the wing-insertions. The tegmina hyaline with a brown neuration. Legs brown and moderately long. Size, 4 x 3 mm. Habitat Adelaide.
The female has the suprahumerals more porrect and acute at the tips. The legs are only slightly dilated. The surface is roughly punctured. Size, 6 x 3 mm ♀, 4 x 2 mm ♂. Habitat Adelaide. Mr. J.O. Tepper's Collection. (Buckton 1903).

The above description from Buckton (1903) appears to be an inadvertent combination of descriptions of two taxa all under the heading "Pterosticta interposita n.s.". Both parts end with size measurements (which differ) and "Habitat Adelaide". How much of this text applies to S. interposita is unclear.
