[2] The species is found extensively in Guatemala, north of Paraguay: Villarrica, Gorgona Island off the coast of Colombia, Cusco in the Peruvian Andes to eastern Brazil, Amazonas region of Venezuela, the island of Trinidad, Suriname, French Guiana, and Belém at the mouth of the Amazon in northeastern Brazil.

[2][3] M. conifera has wings of the greyish brown ground colour.

The triangular white patch on costa is usually prominent, sometimes reduced.

Hindwing: The termen is sometimes weakly sinuate, sometimes rounded; medially semi-translucent with darkish grey-brown colour.

[3] The absence of chestnut brown on the wings of M. conifera distinguishes the species from M. hedylaria and M. cascaria.
