Carpophiline-ID is presented, a matrix-based LucidTM key, for the adult stage of the known species of Carpophilinae (Coleoptera: Nitidulidae) of North America, east of the Mississippi River. An overview of the features and technical specifications used to build the key is provided. The list of terminal taxa used in the key represents the most current regional account for Carpophilinae, a beetle subfamily of agricultural and ecological importance. The value of matrix-based, free access keys for the identification of difficult taxa is discussed.

A New Species

Millipedes of the genus Apheloria Chamberlin, 1921 occur in temperate broadleaf forests throughout eastern North America and west of the Mississippi River in the Ozark and Ouachita Mountains. Chemically defended with toxins made up of cyanide and benzaldehyde, the genus is part of a community of xystodesmid millipedes that compose several Müllerian mimicry rings in the Appalachian Mountains. We describe a model species of these mimicry rings, Apheloria polychroma n. sp., one of the most variable in coloration of all species of Diplopoda with more than six color morphs, each associated with a separate mimicry ring.

Bees in the subgenus Lasioglossum (Dialictus) are commonly collected, behaviourally diverse and taxonomically challenging. The metallic species of Lasioglossum (Dialictus) occurring east of the Mississippi River are revised. Taxonomic treatments of all 97 species are provided with complete descriptions and illustrations given for the 40 species, which have not been recently described elsewhere. Identification keys for males and females are provided. The following eleven new species are described: Lasioglossum (Dialictus) arantium new species, L. (D.) ascheri new species, L. (D.) batya new species, L. (D.) curculum new species, L. (D.) furunculum new species, L. (D.) georgeickworti new species, L. (D.) gotham new species, L. (D.) izawsum new species, L. (D.) katherineae new species, L. (D.) rozeni new species, and L. (D.) trigeminum new species. Lasioglossum ascheri, L. curculum, L. furunculum, L. izawsum, and L. rozeni are believed to be social parasites or cleptoparasites of nest-building L. (Dialictus). Lasioglossum (D.) smilacinae (Robertson) is resurrected from synonymy with L. laevissimum (Smith). Lasioglossum (D.) nymphaearum (Robertson) is resurrected from synonymy with L. albipenne (Robertson).Lasioglossum rufulipes (Cockerell) and L. testaceum (Robertson) are removed from Evylaeus and placed in Dialictus. The following eleven new synonymies are proposed (junior subjective synonym listed second): L. (D.) flaveriae (Mitchell) = Dialictus tahitensis Mitchell; L. (D.) leucocomum (Lovell) = Dialictus otsegoensis Mitchell; L. (D.) lionotum (Sandhouse) = Paralictus asteris Mitchell; L. (D.) longifrons (Baker) = L. (Chloralictus) robertsonellum Michener; L. (D.) nigroviride (Graenicher) = Evylaeus pineolensis Mitchell; L. (D.) simplex (Robertson) = Halictus (Chloralictus) malinus Sandhouse; L. smilacinae (Robertson) = Halictus zophops Ellis, = D. philanthanus Mitchell; L. (D.) testaceum (Robertson) = Halictus (Chloralictus) scrophulariae Cockerell, = Lasioglossum (Chloralictus) sandhouseae Michener; and L. (D.) versans (Lovell) = Evylaeus divergenoides Mitchell. Lectotypes are designated for Halictus albipennis Robertson (1890), Halictus albitarsis Cresson (1872), Halictus cressonii Robertson (1890), Halictus disparilis Cresson (1872), Halictus hortensis Lovell (1905), Halictus nubilis Lovell (1905), Halictus pilosus leucocomus Lovell (1908), Halictus planatus Lovell (1905), Halictus stultus Cresson (1872), Halictus subconnexus rohweri Ellis (1915), Halictus tegularis Robertson (1890), Halictus versans Lovell (1905), and Halictus viridatus Lovell (1905).

First Time

Scholars have argued that plant domestication in eastern North America involved human interactions with floodplain weeds in woodlands that had few other early successional environments. Archeological evidence for plant domestication in this region occurs along the Mississippi river and major tributaries such as the Tennessee, Ohio, Illinois, Missouri, and Arkansas rivers. But this region is also known as the prairie peninsula: a prairie-woodland mosaic that was maintained by anthropogenic fire starting as early as 6000 BP. Contrary to conventional wisdom, recent research has shown that bison were also present in the prairie peninsula throughout the Holocene. Recent reintroductions of bison to tallgrass prairies have allowed ecologists to study the effects of their grazing on this ecosystem for the first time. Like rivers and humans, bison create early successional habitats for annual forbs and grasses, including the progenitors of eastern North American crops, within tallgrass prairies. Our fieldwork has shown that crop progenitors are conspicuous members of plant communities along bison trails and in wallows. We argue that ancient foragers encountered dense, easily harvestable stands of crop progenitors as they moved along bison trails, and that the ecosystems created by bison and anthropogenic fire served as a template for the later agroecosystem of this region. Without denying the importance of human-river interactions highlighted by previous researchers, we suggest that prairies have been ignored as possible loci for domestication, largely because the disturbed, biodiverse tallgrass prairies created by bison have only been recreated in the past three decades after a century of extinction.

Scientific Libraries

The students of general herpetology in this country have labored under great disadvantage, as the descriptions of American Batrachia and Reptilia are scattered through many works, which are rarely found except in large scientific libraries. In the following pages an attempt is made to describe, in convenient form, the species found in Eastern North America, and the higher groups to which they belong. The nomenclature and classification used are the same as that adopted by Prof. E. D. Cope in his Check List of North American Batrachia and Reptilia. In order to facilitate the identification of specimens, and in order that the catalogue may be available to the greatest number, when easily recognizable characters did not exist in the natural synopses, they were added in artificial ones.

The pseudoscorpion genus Hesperochernes presently includes 19 species, 17 of which are endemic to North America. On this continent, most species in the genus have been found in association with bats or rodents, and six species are known exclusively from subterranean habitats. Three species are distributed south of the Great Lakes in the eastern part of the mainland continent: H. holsingeri, H. mirabilis, and H. occidentalis. All three have only been collected from karst caves. Hesperochernes holsingeri is presumed to be endemic to one cave in southern Indiana in the Interior Low Plateau karst region. Specimens attributed to H. mirabilis are widely distributed across all karst regions east of the Mississippi River, excluding the Florida Lime Sink. Specimens identified as H. occidentalis are restricted to west of the Mississippi River, where they are broadly distributed in the Ozarks karst region. These three species were defined from morphological characters that have since been speculated to suffer from a high degree of variation among populations. This ambiguity has effectively rendered unreliable any species-level determinations of Hesperochernes from caves in eastern North America. Additionally, previous authors have noted that there exists high potential for undescribed diversity within this geographic distribution of the genus. The present study seeks to disentangle relationships within Hesperochernes from subterranean populations in eastern North America. Within this region, we collected 95 samples of Hesperochernes and nine samples of outgroup pseudoscorpions from 53 caves located in the Appalachians, Ozarks, and Interior Low Plateau karst regions. The 3RAD restriction-associated digest (RADseq) method was used to sample thousands of loci from across the whole genome. Population genetics, species delimitation, phylogeographic, and morphological analyses are presented that will inform a taxonomic revision of this remarkably successful, exclusively hypogean species complex of pseudoscorpions.
