Four tables are included that list new geographical records and one table that notes new host records. Seventy-eight flea species (some of the same species were new for different state, county and provincial records) accounted for 129 new U.S. state or Canadian provincial records.

Kohls (1940) suggested that there are intergrades of these subspecies in sympatric areas of southeastern Washington and Oregon, south central Idaho, and Utah. Kohl's conclusions were based on traditional morphological features of the “clasper” (basimere and telomere) and chaetotaxy of the outer surface of the hind tibia. These morphological features, and that of the aedeagus, have never been critically studied until now. The aedeagi of both taxa were examined and several consistent structures separate these closely allied species. The median dorsal lobe and apex of the sclerotized inner tube show little variation, although they are distinctly different among the sympatric populations and are consistent in peripheral populations. These characters are stable with little variation and their structure appears to be sufficiently different to potentially inhibit interbreeding that typically occurs where subspecies meet. These characters are valid distinguishing characters even when males of both species occur simultaneously on the same host. These newly reognized static characters of the aedeagus are illustrated. The lateral surface of the hind tibia is the most valid criterion for separation of females of the two species, although this cannot be determined with any degree of certainty. Spilopsyllus inaequalis interrupta is herein elevated to full specific status (Spilopsyllus interruptus) (Amended Status).

Although previously suggested as a synonym of Leptictis montanus (Douglas, 1905), L. intermedius is recognized as a distinct species based on its smaller size, cranial features (narrower zygomatic arch, single squamosal sinus canal, large suprameatal foramen), and dental features (paraconule transversely elongated and more lingual than metaconule on P5–M3; and metacone moderately to well developed on M3). Leptictis thomsoni (Matthew, 1903) is referred to a new genus, Stenoleptictis based on previously undescribed lower dentitions and crania from both Pipestone Springs (type locality) and McCarty's Mountain. The most diagnostic characters of Stenolepticis thomsoni (Matthew, 1903), new combination, are the lingually narrower upper cheek teeth with reduced anterior cingula and the presence of more lateral, lyrate parasagittal crests on the cranium, features unreported in any other leptictids.","PeriodicalId":50771,"journal":{"name":"Annals of Carnegie Museum","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2022-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84597972","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Fragmented population stands of buffalo nut in Pennsylvania, USA, represent the northern–most range of distribution of the species. These leading–edge populations could be the originators for new stands expected to arise as climate change shifts this species' native range further north. When observing an isolated stand of buffalo nut, it is impossible to be sure if individual trees are clones of a common parental plant or the product of sexual reproduction. Our study represents the first attempt to use population genetic methodologies to determine the genetic relatedness of individual plants in fragmented stands, and to assess the genetic diversity of native buffalo nut populations in North America. Our study used microsatellite markers to compare genetic variation in samples from populations in Pennsylvania to samples collected in other populations in the northern end of its range (i.e., West Virginia, Kentucky, and Virginia). We found 1) that trees could not be located at most sites, and 2) that Pennsylvania populations are largely clonal with little genetic diversity among locations within the state (∼200 km2) relative to populations sampled in Kentucky and Virginia. We provide best practice suggestions for conservation of this species.","PeriodicalId":50771,"journal":{"name":"Annals of Carnegie Museum","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2022-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73122789","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Likewise, these very responses to spatial differences in climate, we proffer, predispose the Eastern American Toad to climate-change related shifts in timing of reproduction in Pennsylvania.
