Description of adults: Following Cockerell, 1919. "Length a little over 2 mm., anterior wing about 2.3 mm.; body and appendages dark brown; wings pale brown, hyaline, without evident scaling (probably denuded); eyes very prominent, much more convex than in Mnemonica; maxillary palpi elongate, so far as visible similar to those of Mnemonica; wings very similar to those figured by Comstock´s Manual for the Study of Insects, pg. 216, but R1a runs to the costa, as in Comstock´s figure of Mnemonica ("The Wings of Insects" pg. 314); the course of the media, except the apical branches, cannot be made out. The five branches of the radius all end separately; the two anals run parallel, very close together. The frenulum, with four well-developed bristles, agrees with Tillyard´s recent figures (Proc. Linn. Soc. N. S. W., 1918), and the humeral lobe of the hind wing is very distinct."

Distribution:

The species is known only from the single type specimen, which has been found in Burmese amber. The latter is assumed to be of Cretaceous origin, embedded in Miocenic clay (Cockerell 1922). Its age therefore is between 112.2 - 98.9 Ma (anonymous 2010).

Anatomy:

The sex of the specimen has not been determined. From the available pictures it is also not possible to conclude anything about genitalic morphology.

Diagnosis:

So far, it has not been possible to reinvestigate the type specimen for possible apomorphies, that would allow a certain placement of the species within Micropterigidae. Available literature too, does not allow such an assignement. On the other hand, it is obvious, that the taxon cannot be placed in genus Sabatinca, since the latter is highly inhomogenous and evidently not monophyletic.
