Interpretive Summary: The caterpillars of many moths in the family commonly known as “leaf rollers” attack crops, ornamental plants, and forest trees, causing millions of dollars in damage annually. In this paper, a new genus and five new species are recognized and named, all of which feed on the cones of pine trees. These findings will be of interest to forest managers, scientists involved in biodiversity inventories of North America, and USDA-APHIS personnel at U.S. ports-of-entry whose job it is to detect and exclude non-native species from the U.S.
Technical Abstract: Eupinivora, new genus, is described and illustrated from the montane regions of western United States (Nevada, Utah, Wyoming, Colorado, Arizona, New Mexico, and Texas) and northern Mexico (Nuevo León and Durango). As presently defined, the genus includes six species: E. ponderosae, n. sp. (USA: Arizona) (type species); E. angulicosta, n. sp. (Mexico: Nuevo León), E. albolineana, n. sp. (Mexico: Durango), E. hamartopenis (Razowski, 1986), n. comb. (Mexico: Durango), E. unicolora, n. sp. (Mexico: Durango), and E. rufofascia, n. sp. (Mexico: Durango). The new genus is most closely related to Henricus Busck, 1943, from which it can be distinguished by a variable cluster of long spinelike external setae from near the middle of the phallus in the male genitalia, the absence of a cornutus in the vesica, a forewing pattern that in most of the included species is reminiscent of that of Argyrotaenia ponera Walsingham and its relatives, and short upturned labial palpi. Four of the new species were reared from Pinus arizonica var. cooperi Blanco (Pinaceae) and one from Pinus ponderosa P. & C. Lawson; all of the species occur in habitats dominated by conifers at elevations between ca. 1700 and 2700 m. Two specimens from New Mexico were collecting in traps baited with a synthetic pheromone for the bud worm Choristoneura lambertiana (Busck, 1915) (Archipini) – 90% 92:8E:Z11-14AC, 10% 90:10E:Z11OH – which is consistent with that recorded for other Cochylina.
