Recent Progress on the Study of Minnesota Mayflies (Insecta: Ephemeroptera) ABSTRACT The last comprehensive study of the species of Recent Progress on the Study of mayflies (Insecta: Ephemeroptera) in the state of Minnesota occurred in the 1940s: there were Minnesota Mayflies approximately 60 species identified at that time. We have compiled an updated list of 105 (Insecta: Ephemeroptera) species through the inclusion of new and historical data, including our own fieldwork and Andrew K. Usher & Luke M. Jacobus review of extensive collections at the University of Minnesota. This number is now comparable Div. Science, Indiana Univ.

China. This is the first species of the family Behningiidae discovered in China. It is also the second species of genus Behningia, and the third species of the family Behningiidae collected from the Oriental biogeographic region. The shapes of the labrum and the labium in B. nujiangensis are markedly different from those found in other species of Behningia. Differences in the mandibles, the galea-lacina of maxillae, and both the prothoracic and metathoracic legs differentiate B. nujiangensis from both B. baei and B. ulmeri. The biology of and conservation challenges for B. nujiangensis are also briefly discussed.

  • 9 a New Record of Burrowing Mayfly, Anthopotamus Neglectus Neglectus
    Ohio Biological Survey Notes 10: 9–12, 2021. © Ohio Biological Survey, Inc. A New Record of Burrowing Mayfly, Anthopotamus neglectus neglectus (Traver, 1935) (Ephemeroptera: Potamanthidae), from Ohio, USA DONALD H. DEAN1 1Departments of Entomology and Chemistry & Biochemistry, 484 W. 12th Ave., The Ohio State University, Columbus, OH USA 43214. E-mail: [email protected] Abstract: A new state record for a mayfly (Ephemeroptera) was collected on the Olentangy River, Delaware County, Ohio, USA. Anthopotamus neglectus Traver (1935) were collected as nymphs and subsequently reared to adults. Keywords: Olentangy River, Delaware County, Ohio Introduction The neglected hackle-gilled burrowing mayfly, or the golden (or yellow) drake to fly fishers, Anthopotamus neglectus was first described by Traver (1935) as Potomanthus neglectus. Bae and McCafferty (1991) reorganized the family Potomanthidae and placed the taxon in a new genus, Anthopotamus McCafferty and Bae (1990). They further divided the species into two subspecies, A. neglectus neglectus and A. neglectus disjunctus. The geographic range of the former species was originally given as a small circle centered in New York. The latter species was centered in the south-central United States. More recently, A. neglectus neglectus has been reported in eastern North America including Ontario, Alabama, Arkansas, Maryland, Missouri, Mississippi, New York, Oklahoma, Tennessee, Virginia, and West Virginia (Randolph, 2002). The online database NatureServe Explorer (2019) lists the range of A. neglectus neglectus as previously stated, with the addition of Georgia and Pennsylvania (but it includes the caveat “Distribution data for U.S. states and Canadian provinces is known to be incomplete or has not been reviewed for this taxon”).

    insects Article The Imaginal Characters of Neoephemera projecta Showing Its Plesiomorphic Position and a New Genus Status in the Family (Ephemeroptera: Neoephemeridae) Zhenxing Ma and Changfa Zhou * College of Life Sciences, Nanjing Normal University, Nanjing 210023, China; [email protected] * Correspondence: [email protected]; Tel.: +86-139-5174-7595 Simple Summary: The phylogenetically problematic Neoephemeridae is a small family of the order Ephemeroptera, including four genera reported previously. They are genera Neoephemera (in Nearctic region), Ochernova (Central Asia), Leucorhoenanthus (West Palearctic) and Potamanthellus (East Palearctic and Oriental regions), which were geographically isolated until the Neoephemera projecta Zhou and Zheng, a species reported in 2001 from Southwestern China, connected them together. In this work, the imaginal stage and biology of Neoephemera projecta are first observed and described. Furthermore, a series of autapomorphies and plesiomorphies of it are recognized and discussed. Morphologically and biologically, this species is significantly different from other genera and deserves a new plesiomorphic position in the Family Neoephemeridae. Therefore, a new genus Pulchephemera gen. n. is established to reflect its primitive position and intermediate characters of two clades of the family. In addition, some shared characters of this new genus and the family Ephemeridae provide a new perspective or possibility on the phylogeny of Neoephemeridae within Citation: Ma, Z.; Zhou, C. The the order Ephemeroptera.

They are common and abundant in stream riffles and pools, at lake margins and in some cases lake bottoms. All mayfly larvae are aquatic with terrestrial adults. In most mayfly species the adult only lives for 1-2 days. Consequently, the majority of a mayfly’s life is spent in the water as a larva. The adult lifespan is so short there is no need for the insect to feed and therefore the adult does not possess functional mouthparts. Mayflies are often an indicator of good water quality because most mayflies are relatively intolerant of pollution. Mayflies are also an important food source for fish. Ephemeroptera Morphology Most mayflies have three caudal filaments (tails) (Figure 4.1) although in some taxa the terminal filament (middle tail) is greatly reduced and there appear to be only two caudal filaments (only one genus actually lacks the terminal filament). Mayflies have gills on the dorsal surface of the abdomen (Figure 4.1), but the number and shape of these gills vary widely between taxa. All mayflies possess only one tarsal claw at the end of each leg (Figure 4.1). Characters such as gill shape, gill position, and tarsal claw shape are used to separate different mayfly families.

Siphlonisca aerodromia Needham has a univoltine life history in Maine. Adults emerge in late May or early June. Each female contains about 394 large (0.46 mm long) eggs covered with coiled fibers that anchor the eggs to the substrate. Eggs are deposited in the main channel of the stream and small nymphs appear in January. Nymphal growth rate (GHW)was expressed as a percent per day increase in head width. Initially nymphs feed on detritus and grow slowly (GHW= 0.28-0.79) at water temperatures near 0°C. Following snow melt, the nymphs move into the adjacent Carex floodplain. Here, water temperature increases, animal material, in the form of mayfly nymphs, becomes increasingly common in the diet, and growth rate increases (GHW = 2.13-2.89). The sex ratio of nymphs collected in May and June was 1: 1.8 (ma1e:female). GIBBS,K. E., et T. M. MINGO. 1986.

  • Higher Classification of the Burrowing Mayflies (Ephemeroptera: Scapphodonta)1
    84 ENTOMOLOGICAL NEWS HIGHER CLASSIFICATION OF THE BURROWING MAYFLIES (EPHEMEROPTERA: SCAPPHODONTA)1 W. P. McCafferty' ABSTRACT: A revised cladogram of the monophyletic groups of genera constituting the tusked bur­ rowing mayflies (infraorder Scapphodonta) is presented, based in part on new analyses of relationships that have recently appeared in the literature. A new strict phylogenetic higher classification of Scapphodonta that incorporates both extant and extinct taxa and that reflects the revised cladogram is presented. Aspects include the new superfamilies Potamanthoidea (Potamanthidae and Australiphe­ meridae) and Euthyplocioidea (Euthyplociidae and Pristiplociidae), and a newly restricted Ephem­ eroidea (Ichthybotidae, Ephemeridae s.s., Palingeniidae and Polymitarcyidae s.s.). Sequencing con­ ventions allow recognition of multiple scapphodont superfamilies, ephemeroid families and polymitar­ cyid subfamilies. Pentagenia is placed in Palingeniidae, and Cretomitarcys is removed from the Scapphodonta. KEY WORDS: Higher classification, burrowing mayflies, Ephemeroptera, Scapphodonta The Ephemeroptera infraorder Scapphodonta is equivalent to what was recently considered the superfamily Ephemeroidea by McCafferty (1991) and others. It is a grouping hypothesized to be the sister clade of the infraorder Pannota, or the pan­ note mayflies, within the suborder Furcatergalia (Mccafferty and Wang 2000). The Scapphodonta are technically the "tusked burrowing mayflies" and as a mono­ phyletic group demonstrate a defining apomorphy of having larval tusks derived from the outer body of the mandible (e.g., see Bae and Mccafferty 1995). Scap­ phodonta does not include other furcatergalian mayflies constituting the Behningi­ idae (the infraorder Palpotarsa, or tuskless "primitive burrowing mayflies") or the few specialized Leptophlebiidae (infraorder Lanceolata) that are also known to bur­ row and may possess tusks that are not homologous with scapphodont tusks (e.g., see Bae and McCafferty 1995, Edmunds and McCafferty 1996).

Bandeirantes, 3900, Ribeirão Preto, São Paulo, Brasil Polymitarcyidae is a family of burrowing mayflies (Ephemeroptera: Ephemeroidea) distributed throughout the world but with highest diversity in the Neotropics. Tortopus Needham & Murphy, with a Panamerican distribution, is known from twelve species described in the adult stage. Nymphs are only known for three species: T. puella (Pictet), T. obscuripennis Domínguez and T. sarae Domínguez, and present a rather homogeneous morphology (Molineri 2008). They were firstly described for T. puella by Scott et al. (1959) and later Molineri (2008) described the other two. Both studies reported that these species burrow U-shaped tunnels in clay banks of rivers and streams, thus preventing them from being sampled in most limnological studies (that use surbers, drags, or drift nets). The aim of the present contribution is to describe and illustrate the previously unknown nymph of Tortopus harrisi Traver that shows important anatomical differences with the other nymphs known in the genus. This morphological differentiation suggests a different habitat use by these nymphs, sampled with drag and surber samplers in sandy substrate. New locality records are given for T.

  • New Jersey Amber Mayflies: the First North American Mesozoic Members of the Order (Insecta; Ephemeroptera)
    New Jersey amber mayflies: the first North American Mesozoic members of the order (Insecta; Ephemeroptera) Nina D. Sinitshenkova Paleontological Institute ofthe Russian Academy ofSciences, Profioyuznaya Street 123, Moscow 117647, Russia Abstract The following new genera and species of mayflies are described from Upper Cretaceous (Turonian) amber from Sayreville, New Jersey, U.S.A: Cretomitarcys lu=ii (imago male), (Polymitarcyidae: Cretomitarcyinae, new subfamily), Borephemera goldmani (imago male, Australiphemeridae), Amerogenia macrops (imago female) (Heptageniidae) and Palaeometropus cassus (subadult male) (Ametropodidae). Previously no mayflies were described from the Mesozoic of North America. Ametropodidae and Heptageniidae are newly recorded for the Mesozoic, and Australiphemeridae for the Upper Cretaceous. The mayflies in this amber probably inhabited a medium-sized or large river. Zoogeography of Upper Cretaceous mayflies is briefly discussed; with particular emphasis on significant faunistic differences between the temperate and subtropical areas. Introduction often abundant in drift of modern rivers, lotic nymphs seem to be very rare in the fossil record Through the kindness of Dr. D. Grimaldi like other insects inhabiting running waters (Department of Entomology, American Museum (Zherikhin, 1980; Sinitshenkova, 1987).
