Tarache bilimeki

There are a number of species Tarache bilimeki could be confused with. Tarache huachuca lacks strong costal markings as does bilimeki. However the brown band around the forewing postmedial line is stronger in huachuca and has a strong scattering of bluish scales from the inner margin to the costa. These blue scales are absent in bilimeki. Also the suberminal region of bilimeki has a gray band. This gray band is missing is huachuca.

The costal markings of bilimeki, if even present, are weak and yellowish. The three species Tarache new species 2, T. lanceolata, and T. axendra have strong markings at least at the inception of the postmedial line on the costa. The costal markings of lanceolata are yellowish, but much stronger than in bilimeki. In addition the overall coloration of bilimeki is tinted with yellow, not white as in lanceolata.
