Culicoides Latreille and Leptoconops Skuse biting midges of the southwestern United States with emphasis on the Canyonlands of southeastern Utah (Diptera: Ceratopogonidae) Author Phillips, Robert A. 2962 Desert Road Moab, UT 84532 USA text Insecta Mundi 2022 2022-01-28 2022 907 1 214 journal article 10.5281/zenodo.6391684 1942-1354 6391684 CBD29188-143B-44DF-BE21-1654D50D8621 Culicoides owyheensis Jones and Wirth Culicoides owyheensis Jones and Wirth, 1978: 57 (misspelled as owyheenis ; key; female; Idaho ). Wirth et al. 1985: 36 (numerical characters; fig. female wing). Diagnosis. ( Tables 14 , 15 , 17 , 18 ) Brown with some yellow; wing without pattern of pale spots (as in Fig. 3 C . stonei ); two sclerotized ovoid spermathecae and fingerlike vestigial third (as in Fig. 45 C . stonei ); posterior portion of female sternite 8 cleft, with blunt submedian posterior projections (as in Fig. 45 C . stonei ); ventroposterior membrane of male sternite 9 spiculate; aedeagus Y-shaped, median process stout, short, blunt, half as long as basal arms; parameres separate, simple, apex curved hooklike (as in Fig. 41 C . mortivallis ). To distinguish from C . mortivallis , ratios to length of flagellomere 9:>1.50 for flagellomeres 7+8,>3.95 for proboscis,>1.90 for palpal segment 3. Distribution. Idaho (Owyhee County), Utah (Grand County). Adult behavior. R. H. Jones and H. W. Potter Jr. collected females from the ear of a sheep prostrate with bluetongue in Idaho ( Jones and Wirth 1978 ). However, I think that C . owyheensis may be a junior synonym of C . mortivallis , and the record may be for that species. Remarks. Using the measurement ratios from Wirth and Jones (1978: 57) , 2 of 17 specimens recognized as either C . owyheensis or C . mortivallis based on SCo pattern were identified as C . owyheensis ( Table 18 ).
