Hemiarcha bleptodes is a moth in the Gelechiidae family. It was described by Turner in 1919. It is found in Australia, where it has been recorded from Queensland and New South Wales. The wingspan is 12-14 mm. The forewings are blackish suffused and irrorated with white and with white markings. There are six dots on the costa, the three basal rather elongate and more or less produced into the disc. There is an oblique fascia from one-third of the costa to the mid-dorsum, its anterior edge twice indented, the posterior edge less defined. A postmedian central discal spot is divided by a narrow transverse septum and there is an ill-defined narrow subterminal fascia, as well as a slender interrupted submarginal line. The hindwings are pale-grey.
