Additional records are given for the mayfly Paracloeodes minutus (Daggy).
The mayflies (Ephemeroptera) of New Hampshire: Seasonality and Diversity of the Stream Fauna(1)
Transactions of the American Entomological Society, 2006
Season-long sampling in streams and rivers produced 112 species of mayflies, which with other records totals 121 species for New Hampshire; 88 of these are new state records. Appearance of blackwing/mature larvae were used to develop statements on seasonality of species. Distinct differences were found between the faunas of southern and northcentral New Hampshire, with an important factor being water temperatures through the season. A biogeographic analysis coupled with known habitat preferences reinforced the hypothesis that water temperature was a critical factor in determining species distributions in the state.

Ohio is an eastern USA state that historically was >70% covered in upland and mixed coniferous forest; about 60% of it glaciated by the Wisconsinan glacial episode. Its stonefly fauna has been studied in piecemeal fashion until now. The assemblage of Ohio stoneflies was assessed from over 4,000 records accumulated from 18 institutions, new collections, and trusted literature sources. Species richness totaled 102 with estimators Chao2 and ICE Mean predicting 105.6 and 106.4, respectively. Singletons and doubletons totaled 18 species. All North American families were represented with Perlidae accounted for the highest number of species at 34. The family Peltoperlidae contributed a single species. Most species had univoltine-fast life cycles with the vast majority emerging in summer, although there was a significant component of winter stoneflies. Nine United States Geological Survey hierarchical drainage units level 6 (HUC6) were used to stratify specimen data. Species richness was significantly related to the number of unique HUC6 locations, but there was no relationship with HUC6 drainage area. A nonparametric multidimensional scaling analysis found that larger HUC6s in the western part of the state had similar assemblages with lower species richness that were found to align with more savanna and wetland habitat. Other drainages having richer assemblages were aligned with upland deciduous and mixed coniferous forests of the east and south where slopes were higher. The Ohio assemblage was most similar to the well-studied fauna of Indiana (88 spp.) and Kentucky (108 spp.), two neighboring states. Many rare species and several high quality stream reaches should be considered for greater protection. A peer-reviewed open-access journal R. Edward DeWalt et al. / ZooKeys 178: 1-26 (2012) 2

Sampling the Lower Mississippi River (LMR) main channel and secondary channels during 2014-2015 and subsequent dietary analysis of river sturgeons (Scaphirhynchus spp.) captured in the Missouri River resulted in the collection of larvae of six mayfly species that specialise in large river habitats. Some of these mayflies are found in large numbers when encountered, while others are infrequently collected and always in low numbers. Two species, Raptoheptagenia cruentata (Walsh, 1863) and Cercobrachys sp. cf. serpentis Sold an, 1986 (Insecta: Ephemeroptera) are reported for Mississippi for the first time. Pseudiron centralis McDunnough, 1931 and R. cruentata are reported for Arkansas for the first time. Updated North American distributions are presented and include records available in major collections and published literature. The apparent restriction of these taxa to large river environments highlights the need for implementation of conservation and restoration efforts to ensure their persistence.
Chironomidae (Diptera) of Cedar Bog, Champaign County, Ohio
Chironomidae (Diptera) were collected from Cedar Bog, Champaign County, OH. Cedar Bog is an alkaline fen formed by numerous springs that collect to form Cedar Run. An attempt was made to collect all life history stages and to rear late instar larvae and pupae under laboratory conditions. Ninety-six taxa were collected from the fen. Twelve taxa were recognized as new species. Taxa for which this study represent a significant range extension are: Bethbilbeckiafloridensis Fittkau & Murray, Paramerina smithae (Sublette), Radotanypus florens (Johannsen) n. comb., Odontomesa ferringtoni Saether, and Rheocricotopus (s.s.) effusoides Saether.

Qualitative collections of aquatic insects were made at Fort Sill, Lawton, Oklahoma, between 2002 and 2004. Ephemeroptera, Plecoptera, Trichoptera, Odonata, Coleoptera, aquatic Heteroptera, Neuroptera, and Megaloptera were targeted. Additional records are included from a survey that took place in 1999. More than 11,000 specimens from more than 290 collections were examined. Based on the current understanding of aquatic insect systematics, 276 taxa distributed over 8 orders, 46 families, and 141 genera were identified. Twenty-three of the 276 taxa, Plauditus texanus Wiersema, Tricorythodes allectus (Needham), Palmacorixa nana walleyi Hungerford, LeConte are reported from Oklahoma for the first time. The three most diverse orders included Coleoptera (86 species), Odonata (67 species) and Trichoptera (59 species), and the remaining taxa were distributed among Heteroptera, (30 species), Ephemeroptera (21 species), Plecoptera (6 species), Megaloptera (4 species), and Neuroptera (3 species). Based on previous published records, many of the species collected during this study were expected to be found at Fort Sill; however, 276 taxa of aquatic insects identified from such a small geographic area is noteworthy, especially when considering local climatic conditions and the relatively small size of Fort Sill (38,300 ha). Despite agricultural practices in Oklahoma, the dust bowl days, and the development of water-based recreation at Fort Sill, a high percentage of the total known aquatic insect fauna of Oklahoma can be found in a small geographic area.

I could not have completed this work without the help and support of many individuals. First and foremost, I wish to thank my advisor, Dr. Len Ferrington, for all of the guidance, discussion, support, and encouragement he has offered over the past five years, and, of course, for sharing and passing on his passion and fascination with Chironomidae research. Len has helped to both focus and broaden my interests in aquatic entomology, conservation biology, and science as a whole. Additionally, Len has provided strong support and encouragement for my pursuit of numerous opportunities throughout the course of my graduate career, including research grants and fellowships, teaching and presentation opportunities, and international research and scholarship activities, all of which have greatly contributed to and enhanced my scholarly and professional development. Secondly, many thanks also go to Dr. Torbjørn Ekrem and Dr.
