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 ( Diphaomyia ) erikae Atchley and Wirth ( Fig. 76 , 129, 240, 271) Culicoides ( Diphaomyia ) erikae Atchley and Wirth, 1979: 532 (key; numerical characters; female; male genitalia; pupa; fig. female antenna, palpus, wing, eye separation, spermathecae, male antenna, parameres, genitalia; New Mexico ). Wirth et al. 1985: 18 (numerical characters; fig. female wing). Diagnosis. ( Tables 14 , 15 ) Wing pattern reduced; r 2 dark; distal pale spots absent from r 3 , m 1 , m 2 , often cua 1 ; spermathecae with sclerotized necks ~2× longer than wide; sclerotized ring on spermathecal duct; ventral apodeme of gonocoxite with two widely divergent processes, footlike; basal arms of aedeagus each with spurlike process on posterior margin, median process of aedeagus narrow parallel-sided, aedeagal ratio ~0.4; parameres separate, each with bulbous submedian lobe and subapical fringe of spines. Distribution. Utah (Box Elder, Grand, Uintah counties), Arizona , New Mexico . Nine of the 14 C . erikae collected were from 2436 m elevation in Uintah County ( Table 7 ), suggesting it is more common at higher elevations than were routinely sampled. Larval ecology. Atchley collected or reared pupae from Silver Creek Canyon, Otero County, New Mexico , in May of 1973 and from Cedar Creek Canyon, Lincoln County, New Mexico , in June of 1973 but did not report details of the habitats ( Atchley and Wirth 1979 ). Adult behavior. The mandibular and lacinial teeth on the female indicate it feeds on vertebrate blood; however, its hosts are unknown.
