Polyhymno paracma is a moth of the Gelechiidae family. It was described by Meyrick in 1909. It is found in Mozambique, Namibia, South Africa (Gauteng, Mpumalanga, Limpopo) and Zimbabwe.
The wingspan is 13-14 mm. The forewings are ochreous-fuscous with a broad shining white sharply-defined median streak from the base to beyond five-sixths, the apex acute, the lower margin prominent beyond the middle of the wing and sending a fine branch along the fold almost to the tornus. There is a narrow shining, white subdorsal streak from the base to the tornus and a whitish line along the costa from about one-fourth to the middle, then obliquely to above the apex of the median streak. An oblique white striga is found from the costa about three-fourths to near the termen, the apex leaden-grey. There is also a suffused leaden-grey mark along the upper part of the termen. The hindwings are grey.
