Melanagromyza minima is related to Melanagromyza bidens Spencer and Melanagromyza minimoides Spencer, and it is differentiated especially by the elongated ovipositor in the female (Fig. 83 in Spencer & Stegmaier 1973), and by the shape of male genitalia. Larvae of this species are associated with Asteraceae species, mostly to plants of the genera Wedelia Jacq. and Eupatorium L.
