New Distribution

Distributions of amphibian and reptile species in northern Mexico are poorly understood when compared to adjacent areas of the southwestern United States. To address this gap in knowledge, we conducted a series of surveys in east-central Chihuahua, Mexico in 2014–2016. We documented 40 new municipality records for amphibian and reptile species by means of high quality digital photos. Photographic surveys offer a low-cost, highly accessible technique for accumulating distributional information.

Group Ii

Sampling of arthropods in ground and woody vegetation habitats in highland areas on the islands of Hawaii and Maui revealed six species of psocids of the genus Liposcelis. Three are new and are here described. L. maunakea sp. n. and L. volcanorum sp. n. are closely related and form a small species complex together with L. nasus Sommerman and L. deltachi Sommerman from southwestern United States and northern Mexico. A key to the species of this complex is included. The third new species, L. kipukae sp. n., is a member of group II-C with only 5 ommatidia in the eye. A key to the known species of group II-C with fewer than 7 ommatidia in the eye is included. First Hawaiian records are presented for L. bostrychophila Badonnel, L. deltachi, and L. rufa Broadhead. The first known males of L. bostrychophila are reported and described. This species is very widespread, but generally parthenogenetic.

Distributional Limits

AbstractCollections of Baetis Leach, Baetodes Needham and Murphy, and Dactylobaetis Traver and Edmunds from the southwestern United States and northern Mexico included new species and new distribution records. The nymphal stages of Baetis sonora n.sp. and Dactylobaetis sinaloa n.sp. are described and figured. Species of Baetis nymphs that were given informal epithets, even though they were described, keyed, and their taxonomic characters figured, are named, or tentatively associated with a described adult. Baetis sp. “A” Morihara and McCafferty is tentatively associated as the nymphal stage of B. adonis Traver, Baetis sp. “B” Morihara and McCafferty is named B. libos, and Baetis sp. “C” Morihara and McCafferty is named B. notos. New collection records extend the known distributional limits of Baetis insignificans McDunnough, Baetodes edmundsi Koss, B. fuscipes Cohen and Allen, and Dactylobaetis mexicanus Traver and Edmunds.

The European grapevine (Vitis vinifera L.) has been cultivated in North America for about 500 years. One of the major limitations to its culture is the powdery mildew (PM) fungus, Erysiphe necator Schw. This study reports on the most extensive screening of Vitis species from the southwestern United States and northern Mexico for resistance to PM, testing 147 accessions of 13 Vitis species. In addition, Vitis vinifera cv. Carignane, a highly susceptible wine grape cultivar, was used as a reference to evaluate the effect of the inoculum 14 days postinoculation. Inoculation was done with a vacuum-operated settling tower using a broadly virulent isolate of E. necator, the C-strain. Resistant accessions (nine), moderately susceptible accessions (39), and highly susceptible accessions (99) were detected. The resistant accessions were then inoculated with an additional fungal isolate, e1-101, and they retained their resistance. Vitis species susceptibility was not associated with a North-South gradation, but Western species were more susceptible than Midwestern and Eastern species. All five of the V. monticola accessions were susceptible, as were the accessions of V. treleasei. The species V. acerifolia, V. candicans, V. cinerea, and V. × doaniana had significantly more resistant to moderately susceptible accessions compared with V. arizonica, V. berlandieri, V. californica, V. × champinii, V. girdiana, V. riparia, and V. rupestris, which had relatively more susceptible accessions than the other species. This research identified new sources of PM resistance in Vitis from the southwestern United States that could be incorporated into PM resistance breeding programs throughout the world.
