    Culicoides (Diphaomyia) inyoensis Wirth and Blanton (Fig. 75, 128, 211, 212) Culicoides (Diphaomyia) inyoensis Wirth and Blanton, 1969a: 565 (female, male; fig. female antenna, palpus, wing, eye separation, spermathecae, leg, male genitalia, parameres; California). Atchley and Wirth 1979: 541 (key; numerical characters; female; male genitalia; fig. female antenna, palpus, wing, eye separation, spermathecae, leg, male genitalia, parameres). Wirth et al. 1985: 18 (numerical characters; fig. female wing). Diagnosis. (Tables 14, 15) Wing pattern extensive; r 2 dark; large distal pale spots in r 3, m 1, m 2, cua 1, but may be diffuse and indistinct; distal pale spot in r 3 centered at ~0.7 the distance from apex of costa to apex of M 1, extending into distal 0.1 of cell; M 1 dark; pale spot barely on M 2 at ~0.4, spreading anterior into m 1; spermathecae subequal, with sclerotized necks; 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 slightly tapering to blunt tip, aedeagal ratio ~0.5; parameres separate, each with bulbous submedian lobe and subapical fringe of spines. Distribution. California, Utah (Garfield, Grand counties). Adult behavior. The mandibular and lacinial teeth on the female indicate it feeds on vertebrate blood; and though its hosts are unknown, the SCo presence on only the proximal flagellomeres suggests it is mammalophilic. Symbionts. Male and female C. inyoensis were parasitized by larval mites (Table 10), which species may indicate its pupal habitat or oviposition site. Remarks. Wirth and Blanton (1969a) discuss C. inyoensis ’ similarity to Culicoides mohave Wirth, which have similar wing and SCo patterns. In the present study, I identified a female C. inyoensis collected by J. N. Belkin from Saratoga Spring, Death Valley, San Bernardino County, California, 30 May 1953, that had been misidentified as C. mohave. It seems likely other specimens identified as C. mohave before C. inyoensis ’ 1969 description are also misidentified. The C. inyoensis type series was collected from Resting Springs, Inyo County, California, 29–30 May 1955, along with several C. mohave. Saratoga Spring is only 32 km away from and ~ 465 m lower than Resting Springs; thus, their habitats overlap in the Mojave Desert environment, with C. inyoensis ranging more northern into the Canyonlands of Utah and C. mohave more southern into the Sonoran Desert of Baja California.Published as part of Phillips, Robert A., 2022, Culicoides Latreille and Leptoconops Skuse biting midges of the southwestern United States with emphasis on the Canyonlands of southeastern Utah (Diptera: Ceratopogonidae), pp. 1-214 in Insecta Mundi 2022 (907) on page 58, DOI: 10.5281/zenodo.639168

    Culicoides nanellus Wirth and Blanton Culicoides nanellus Wirth and Blanton, 1969a: 565 (female, male; fig. female antenna, palpus, wing, eye separation, spermathecae, hind leg, male genitalia, parameres; California). Wirth et al. 1985: 38 (numerical characters; fig. female wing). Diagnosis. (Tables 14, 15) Pale brown; wing pattern reduced, distal pale spots absent from or barely discernable in r 3, m 1, m 2 (similar to Fig. 145, 224 C. hawsi or 148, 237 C. sublettei); tibiae with basal pale band; female palpus fusiform, with a deep sensory pit ~0.4 as wide as segment (pit similar to Fig. 249 C. hinmani); two unequal ovoid spermathecae (ratio 1.06) with fingerlike vestigial third; sclerotized ring on spermathecal duct; ventro-posterior membrane of male sternite 9 bare; gonocoxal apodemes simple, ventral apodeme thin, ~5× longer than wide; midportion of lateral contour of gonostylus slightly concave; aedeagus almost V-shaped, basal arms relatively slender and only slightly curved, each ~10× longer than wide, median process simple, tapering to narrow blunt tip, aedeagal ratio ~0.55; parameres separate, apical half simple thin sinuous. Distribution. California (Mendocino County). Larval ecology. Culicoides nanellus was collected by F.K. Murphy in a treehole trap 1 July 1965 (Wirth and Blanton 1969a). Adult behavior. The mandibular teeth on the female indicate it feeds on vertebrate blood; however, its hosts are unknown. Remarks. Male C. nanellus would most likely be confused with those C. kibunensis that occasionally have five spines in the hind tibial comb; however, C. kibunensis has a more robust aedeagus with thicker basal arms and a broader distal process (Fig. 98). Females are readily distinguished by SCo pattern, antennal ratio, and the distinctive palpal segment 3. No C. nanellus specimens were examined.Published as part of Phillips, Robert A., 2022, Culicoides Latreille and Leptoconops Skuse biting midges of the southwestern United States with emphasis on the Canyonlands of southeastern Utah (Diptera: Ceratopogonidae), pp. 1-214 in Insecta Mundi 2022 (907) on page 116, DOI: 10.5281/zenodo.639168

    Culicoides posoensis Wirth and Blanton (Fig. 97, 151, 236, 272) Culicoides posoensis Wirth and Blanton, 1969a: 562 (female, male; fig. female antenna, palpus, wing, eye separation, spermathecae, male genitalia, parameres; California). Wirth et al. 1985: 38 (numerical characters; fig. female wing). Diagnosis. (Tables 14, 15) Brown; wing pattern reduced, with pale spots only on wing base, at tip of costa, on r-m crossvein; tibiae with faint basal pale band; two subequal ovoid spermathecae with fingerlike vestigial third; sclerotized ring on spermathecal duct; ventro-posterior membrane of male sternite 9 bare; gonocoxal apodemes simple, ventral apodeme thin,>5× longer than wide; aedeagus Y-shaped, basal arms curved, median process simple with truncate tip ~0.2 as wide as basal arch, aedeagal ratio ~0.5; parameres separate, apical half simple thin sinuous. Distribution. California (Kern County). Adult behavior. Using truck traps in Kern County, California, Nelson and Bellamy (1971) found C. posoensis was more abundant in the summer than in the fall, with flight activity through the night with peaks near dusk and dawn. However, little else is known about the biology of this species other than that the mandibular and lacinial teeth on the female indicate it feeds on vertebrate blood.Published as part of Phillips, Robert A., 2022, Culicoides Latreille and Leptoconops Skuse biting midges of the southwestern United States with emphasis on the Canyonlands of southeastern Utah (Diptera: Ceratopogonidae), pp. 1-214 in Insecta Mundi 2022 (907) on page 116, DOI: 10.5281/zenodo.639168

    Culicoides (Amossovia) cochisensis Wirth and Blanton (Fig. 101, 155, 191) Culicoides cochisensis Wirth and Blanton, 1967: 218 (key; female, male, pupa; fig. female antenna, wing, eye separation, spermathecae, leg, palpus, male genitalia, parameres; Arizona; paratype records show Culicoides villosipennis Root and Hoffman record for Utah was a misidentification). Wirth et al. 1985: 20 (numerical characters; fig. female wing). Wirth et al. 1988: 30 (numerical characters; fig. female wing). Murphree and Mullen 1991: 330 (key; larva; numerical characters; fig. epipharynx, mandible, hypostoma, caudal segment). Culicoides (Amossovia) cochisensis: Borkent and Spinelli 2000: 27 (in Neotropical catalog). Culicoides villosipennis Root and Hoffman, misidentified: Bullock 1952: 24 (misspelled as “villosopennis”; key; female [male description invalid]; Utah: Salt Lake County). Rees and Bullock 1954 (misspelled as “villosopennis”; Utah: Salt Lake County). Diagnosis. (Tables 14, 15) Dark brown; wing pattern distinct; r 2 dark; distal pale spot in r 3 medially constricted and roughly C-shaped; pale spots straddling at ~0.2 on M 1 and ~0.4 on M 2; CuA 1 and CuA 2 within dark areas except at tip of CuA 1; pore of sensory pit on palpal segment 3>0.5 the diameter of segment (as in Fig. 247 C. californiensis); pale band subapical on hind tibiae, absent from hind femora and subapically from fore and mid tibiae; ventral apodeme of gonocoxite simple; aedeagus Y-shaped, median process slender to pointed tip; parameres separate, apices simple, pointed. Distribution. California, Utah (Salt Lake City), Arizona, Baja California. The only Utah record is of a female collected at a window in Salt Lake City 14 September 1952 (Bullock 1952). The other collection records are from the Sonoran Desert; hence, it is likely not resident in Utah, and the record is of a transient. Larval ecology and adult behavior. Culicoides cochisensis larvae have been collected from water in a pocket of a saguaro cactus (Carnegiea gigantea [Engelmann] Britton and Rose, Cactaceae) (Wirth and Blanton 1967). However, its adult hosts are unknown, though the mandibular and lacinial teeth on the female indicate it feeds on vertebrate blood.Published as part of Phillips, Robert A., 2022, Culicoides Latreille and Leptoconops Skuse biting midges of the southwestern United States with emphasis on the Canyonlands of southeastern Utah (Diptera: Ceratopogonidae), pp. 1-214 in Insecta Mundi 2022 (907) on pages 45-46, DOI: 10.5281/zenodo.639168

    Thermal expansion anomalies of R(Fe, M)(12) (R=Y, Nd; M=Mo and Si)

    No full text
    Structural and thermal-expansion anomaly studies on R(Fe,M)(12) (R=Nd and and Y, M=Mo and Si) compounds were performed by x-ray diffraction. Mo atoms occupy the 8i site. While Si atoms occupy the 8f and 8j sites but not the 8i site. Thermal-expansion anomaly shows only in ab plane in the Mo compounds, while becomes very weak and along with only the c axis in the Si compounds. The anomaly was attributed to the contribution of the interactions of short Fe-Fe distances similar to the previous explanation on other R-Fe intermetallics and that of other strongly positive interactions such as 8j-8j.

    A 2 h periodic variation in the low-mass X-ray binary Ser X-1

    No full text
    Spectroscopy of the low-mass X-ray binary Ser X-1 using the Gran Telescopio Canarias have revealed a ?2 h periodic variability that is present in the three strongest emission lines. We tentatively interpret this variability as due to orbital motion, making it the first indication of the orbital period of Ser X-1. Together with the fact that the emission lines are remarkably narrow, but still resolved, we show that a main-sequence K dwarf together with a canonical 1.4 M? neutron star gives a good description of the system. In this scenario, the most likely place for the emission lines to arise is the accretion disc, instead of a localized region in the binary (such as the irradiated surface or the stream-impact point), and their narrowness is due instead to the low inclination (?10°) of Ser X-1

    "Closing the R&D Gap, Evaluating the Sources of R&D Spending"

    No full text
    Both spending and tax policies have been implemented in the United States with the goal of stimulating private sector research and development (R&D). Karier questions whether current R&D policy, especially the research and experimentation tax credit, can contribute to closing the gap between nondefense expenditures on R&D in the United States and such expenditures in other countries, such as Japan and Germany. He also explores possible changes to our current R&D policy to make it more effective.
