A New Species

The North American crab spiders are now comparatively well known taxonomically. This is particularly true of the species in the large genus Xysticus, which has been twice revised continentally by Gertsch (1939, 1953) and treated in more regional works by Buckle and Redner (1964), Schick (1965), and Turnbull, et al. (1965). It seems probable that any additional new forms that will be discovered will be from remote parts of the continent or in sibling relationship with known species. Several species have, however, been described only from one sex.The purpose of this paper is to describe a distinctive new species of Xysticus from the mountainous parts of Arizona. Its structure clearly places it in the locuples group of the apophysate division of the genus, and its range suggests it to be an inland endemic of the southwestern United States.

A New Species

This work provides a taxonomic survey of the North American species of the genus Elonus Casey, 1895 (Coleoptera: Tenebrionoidea: Aderidae). It includes the description of a new species, Elonus gruberi n. sp. from the United States, related to E. hesperus Werner, 1990 and to E. basalis (LeConte, 1855). A review and key to the North American species is provided.

AbstractGroup VII of North American Ips contains I. thomasi, new species, I. borealis Swaine and I. swainei R. Hopping. They are less than 4.0 mm. long and females have the front of the head or at least the vertex smooth and shining, impunctate, or with very fine sparse punctures; males are more coarsely granulate-punctate on the frons. The species are described and a key is given. All breed in Picea in Canada and northern United States.

Abstract Based on a recently released, high-resolution reanalysis dataset for the North American region, the intraseasonal variability (ISV; with a time scale of about 20 days) of the North American monsoon (NAM) is examined. The rainfall signals associated with this phenomenon first emerge near the Gulf of Mexico and eastern Pacific at about 20°N. They subsequently migrate to the southwestern United States along the slope of the Sierra Madre Occidental. The rainfall quickly dissipates upon arrival at the desert region of Arizona and New Mexico (AZNM). The enhanced rainfall over AZNM is accompanied by strong southeasterly low-level flow along the Gulf of California. This pattern bears strong resemblance to the circulation related to “gulf surge” events, as documented by many studies. The southeasterly flow is associated with an anomalous low vortex over the subtropical eastern Pacific Ocean off California, and a midlatitude anticyclone over the central United States in the lower troposphere. This flow pattern is in broad agreement with that favoring the “wet surges” over the southwestern United States. It is further demonstrated that the aforementioned low-level circulations associated with ISV of the NAM are part of a prominent trans-Pacific wave train extending from the western North Pacific (WNP) to the Eastern Pacific/North America along a “great circle” path. The circulation anomalies along the axis of this wave train exhibit a barotropic vertical structure over most regions outside of the WNP, and a baroclinic structure over the WNP, thus suggesting the important role of convective activities over the WNP in sustaining this wave train. This inference is further substantiated by an analysis of the pattern of wave-activity–flux vectors. Variations in the WNP convection are correlated with the ISV of the monsoons in both North American and East Asian (EA)/WNP sectors. These relationships lead to notable teleconnections between NAM and the EA/WNP monsoon on 20-day time scales.

A New Species

A new species of apoid wasps, Pseudoplisus willcoxi sp. nov., is described from Arizona, New Mexico, and Colorado. It is compared with all other species currently assigned to the genus. It has a remarkable overall color pattern, unique in Pseudoplisus, and a restricted collecting record: only a single specimen was collected outside of the Willcox area in Arizona (defined here as including the Animas area, New Mexico). Additionally, of the 34 remaining specimens, one was collected in 1974 and all other after 2001. In the present paper, the new species is diagnosed, described, and the relevant characters are illustrated. The geographic distribution and its heterogeneous collecting record are briefly discussed.
