Megacraspedus calamogonus is a moth of the family Gelechiidae. It was described by Edward Meyrick in 1885.[1] It is endemic to New Zealand.[2]

The wingspan is 10–16 mm (0.39–0.63 in). The forewings are whitish-ochreous, with the veins sometimes slightly infuscated. There is a dark fuscous dot in the disc slightly before the middle, a second very obliquely before it on the fold, and a third in the disc at two-thirds. There is also a short fuscous apical streak. The hindwings are whitish.[3]

Larvae of this species feed on the flowers and seeds of grass and sedge plants.[4] Hosts include Austroderia richardii, Chionochloa flavescens, Chionochloa macra, Chionochloa pallens, Chionochloa rigida and Chionochloa rubra.[5]
