"The geometrid moths heretofore assigned to the genera Mericisca Hulst, Tracheops Hulst, Parapheromia McDunnough, and Merisma McDunnough were studied from the United States. The Mexican fauna was also examined for speices that belong to this group. These studies show that the above four groups are not distinct on a generic level, even though each one forms a small and compact group of species. Consequently they have been placed as subgenera of Mericisca. In addition, it was necessary to erect the new subgenus Puebla for two Mexican species. The moths assigned to Mericisca are distributed from Wyoming and the southern Rocky Mountain states and western Texas in the United States, south to the temperate, mountainous regions of Mexico as far as the State of Chiapas and vicinity. A total of 24 species are included in the genus. Nine are described in this revision as new; of these, eight are from Mexico and one is from Arizona and new Mexico. The genus, all subgnera, and each species are described; distributional information is given for all species insofar as known. Keys are given for all subgenera and species. The adults and their genitalia are figured"--P. 345.
