Taxonomy

Ignoring its provenance from 1550 m altitude, M. pachycarpidia may key out beside M. sulcata, a lowland species with smaller fruits. Similar also is M. bialata from lowland areas in the Bismarck Archipelago but that species has twigs with ant-swellings.

The (immature) fruits of M. pachycarpidia may resemble those of M. sphaerosperma, also a montane species, with terete twigs and a much more conspicuous indumentum on the lower leaf surface.
