Odgodoncta moreno Barnes
Ogdoconta moreno Barnes, 1907, Canad. Ent., 39:96.
Diagnosis: Ogdoconta moreno is a light gray-brown moth. It is not likely to be confused with any other species of Ogdoconta in either North America or elsewhere in the range of the genus. The closest North American species appears to be sexta and altura with cinereola not all that distantly related itself. Superficially the three species are not likely to be confused with moreno. Both the reniform spot and orbicular spot of the forewing are represented by conspicuous light patches devoid of any defining lines of spots. The orbicular spot touches the antmedial line. The antemedial line is slightly triangular with the outward apex occurring just below the orbicular spot. The inner side of the antemedial line is a light band followed by a darker brown line. The claviform spot is absent. The postmedial line is an almost striaght, light line, follwed by a light region of the subterminal area. The hindwing of both the male and female is whitish, but suffused with dull gray-brown, more heavily in the female than the male. The male genitalia are unremarkable. The cucullar part of the valve is ovate, elongate, the clasper is absent, and the outer margin of the valve is unmodified. The vesica is elongate without spines or other sclerotizations and contains a half coil. There are, however, minute denticules throughout the middle half of the vesica. The female genitalia are similar to those of cinereola. The most distinctive feature of the female genitalia is the coloration of the ovipositor lobes. In moreno the setal insertions are distinctly lighter than the dark brown of the lobe. The apophyses posteriores are shorter and stubier than in cinereola. The ductus bursae is shorter and slightly thicker and the corpus bursae longer and thinner than in cinereola.
