G. G.Musser and M. D. Carleton in 2005 found M. howi to be similar to some M. cf. lutillus from Papua New Guinea and suggested that it belonged to the M. cervinipes group, including M. bannisteri , M. fraterculus , M. lutillus , and M. obiensis . In their 2017 morphometric analysis on skulls, P H. Fabre and colleagues found M. how: as-
sociated with a group coon of M. burtoni , M. cervinipes , M. cooperae , M. fraterculus , M. frigicola , M. lutillus , and also “ M. burton ?” from Halmahera. Monotypic.
