| Summary: | Key to New World species of Roederiodes 1 Seven or eight weak dorsocentral setae (Fig. 10); ocellar and vertical setae weak (Fig. 10) (only males distinguishable). 2 - Five strong dorsocentral setae (Fig. 11); ocellar and vertical setae strong (Fig. 11). 3 2 Male terminalia with clasping cercus broad and rounded apically (Fig. 17) [Arizona, New Mexico]. R. chillcotti sp. nov . - Male terminalia with clasping cercus narrow, recurved, with stout apical setae (Fig. 29) [Arizona, California, New Mexico]. R. wirthi Chillcott 3 Base of M 2 forming distinct crossvein at apex of cell dm, longer than r-m crossvein (Fig. 8) [Colorado, Utah, Manitoba, Northwest Territories]. R. distinctus Chillcott - Base of M 2 forming indistinct crossvein at apex of cell dm, shorter than r-m crossvein or crossvein absent and veins M 1 and M 2 petiolate, coalescing for short distance (Figs 5, 6, 9). 4 4 Antennal stylus 2 times longer than postpedicel (Fig. 12); upper face brown. 5 - Antennal stylus up to 1.5 times longer than postpedicel (Fig. 7); upper face with blue pruinescence. 7 5 Prescutellar depression with central whitish pruinescent stripe (as in Fig. 14); male terminalia with clasping cercus long and slender anteriorly (Fig. 24) [Arizona, Baja California]. R. notialis sp. nov. - Prescutellar depression without whitish pruinescent stripe (as in Fig. 15); male terminalia with clasping cercus subtriangular (Fig. 23). 6 6 Ocellar setae shorter than postpronotal seta; male unknown [Cocos Island, Costa Rica]. R. wigginsi Wilder - Ocellar setae longer than postpronotal seta; male terminalia with clasping cercus subtriangular, produced posteriorly (Fig. 23) [Southern Appalachians, USA]. R. moultoni sp. nov. 7 Pleura brown to dark brown, with bluish pruinescence (Figs 5, 6); if pale brown, then prescutellar depression with whitish or bluish pruinescent stripe (Fig. 14) or hind tibia with distinct ventral setae [North America, north of Arizona]. 8 - Pleura pale brown, without bluish pruinescence (Fig. 13) [Arizona, Costa Rica] (females ... |
