E-mail: [email protected] 5Corresponding author Abstract A new species of sand-burrowing mayfly (Ephemeroptera: Behningiidae), Behningia nujiangensis Zhou & Bisset, is described based on more than 50 nymphs collected from the Nujiang River in Yunnan Province, P.R. 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. -

The life history, nymphal growth rates, and feeding habits of Siphlonisca aerodromia Needham (Epherneroptera: Siphlonuridae) in Maine. Can. J. Zool. 64: 427-430. 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.

American Sand Burrowing Mayfly Dolania Americana Contributor: W
The American Sand Burrowing Mayfly Dolania americana Contributor: W. Patrick McCafferty D. americana larva (from McCafferty DESCRIPTION Taxonomy and Basic Description The American sand burrowing mayfly was originally described by G.F. Edmunds and J.R. Traver in 1959 from South Carolina based on the aquatic larva, which was the only stage known at that time. Eggs were first described in 1964 by R.W. Koss and adults were first described in 1971 by W.P. McCafferty. This remains the only named species of the strictly American genus Dolania. It is a member of the Northern Hemisphere family Behningiidae (the tuskless burrowing mayflies), of the infraorder Palpotarsa, suborder Furcatergalia, order Ephemeroptera (McCafferty 2004). Behningiidae are one of the smallest families of mayflies, with a total of three genera and six species known worldwide. The Ephemeroptera, or mayflies, are primitive insects that, along with the dragonflies (Odonata), are considered Paleopterous insects; as such, they are not able to fold their wings, as are all other modern insects. Mayflies are aquatic insects, with both the eggs and larvae residing in freshwater. As such, mayflies are a major component of communities of invertebrates that live on or in the bottom substrates of streams and shallow zones of lake and ponds. Mayflies are unique among insects in that in their life cycle, they have a fully winged pre-adult stage known as a subimago as well as a fully winged adult stage. In all other winged insects the fully winged condition is restricted to the reproductively mature adult stage. Both the subimago and adult stages do not feed and are terrestrial (aerial) rather than aquatic. -

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.

Toward a Phylogenetic Classification of the Ephemeroptera (Lnsecta): a Commentary on Systematics
FORUM Toward a Phylogenetic Classification of the Ephemeroptera (lnsecta): A Commentary on Systematics W. P. MCCAFFERTY Department of Entomology, Purdue University, West Lafayette, Indiana 47907 Ann. Entomol. Soc. Am. 84(4): 343-360 (1991) ABSTRACT Higher classifications of Ephemeroptera formulated in light of phylogenetic hypotheses have been essentially evolutionary in that they have incorporated paraphyletic taxa. The term "paraphyletic" has had a confused history because systematists have applied it to different concepts; for Ephemeroptera, it has denoted one type of nonpolyphyletic grouping. Such paraphyletic taxa were used so that large degrees of character (presumably adaptive) differentiation could be expressed, but resulting classifications lack any means of consistently expressing such gaps, and their ability to express genealogy is compromised. Phylogenetic classifications are now strongly advocated. Not only can the increasing number of phylogenetic hypotheses based on cladistic analysis be objectively expressed, but many traditional taxa and categories can be conserved by employing sequencing conventions. The philosophy and history of competing classificatory systems are discussed. A phylogenetic methodology is employed when possible in proposed revisions of the higher taxa of Ephem eroptera. New cladistic data are presented and previous data reviewed. Major lineages formerly part of the paraphyletic family Siphlonuridae are classified as families within several higher taxa to express phylogeny and at the same time maintain -

Kyoto University, Kyoto, 606 JAPAN 1 Functional Morphology of the Genitalia of Epeorus ikanonis (Ephemeroptera: Heptageniidae)* Yasuhiro TAKEMON Department of Zoology, Faculty of Science, Kyoto University, Kyoto, 606 JAPAN Abstract Morphology of the genitalia and other reproductive organs was described for both sexes of the heptageniid mayfly Epeorus ikanonis Takahashi. Specimens fixed during copulation showed that the male genitalia changed in it's shape when inserted in female genitalia. Morphological function of the male genitalia was examined in terms of sperm transfer into the seminal receptacle. And the sperm competition at successive copulation was discussed based on the location of the ejaculated sperm in female reproductive organs. * Contribution from the Laboratory of Animal Ecology, Kyoto University, No. XXX. 2 Introduction Ilarlcrr (1YH(i) pointed out a copulatory movement of penis in mayflies or the genus FMvonurus, and thereby he called attention to the taxonomic use of the morphology of genitalia. He showed that, the dorsal side of each half of the penis lobes rotates inwards during copulation, though the function of this movement has never been explained. -

The Ephemeroptera, or mayflies, are a small but diverse order of amphinotic insects associated with liquid freshwater worldwide. They are nearly cosmopolitan, except for Antarctica and some very remote islands. The existence of the subimago stage is unique among extant insects. Though the winged stages do not have functional mouthparts or digestive systems, the larval, or nymphal, stages have a variety of feeding approaches—including, but not limited to, collector-gatherers, filterers, scrapers, and active predators—with each supported by a diversity of morphological and behavioral adaptations. Mayflies provide direct and indirect services to humans and other parts of both freshwater and terrestrial ecosystems. In terms of cultural services, they have provided inspiration to musicians, poets, and other writers, as well as being the namesakes of various water- and aircraft. -
EPHEMEROPTERA: SIPHLONURIDAE)L,2
-z.ol Vol. 108, No. 2, March &April, 1997 141 CRITICAL COMMENTARY ON THE GENUS SIPHLONISCA (EPHEMEROPTERA: SIPHLONURIDAE)l,2 W. P. McCafferty3, George F. Edmunds, Jr.4 ABSTRACT: Data are presented that contravene certain unfounded statements that have been pub lished regarding Siphlonisca aerodromia, a siphlonurid mayfly from extreme northeastern U.S.A. and eastern Canada. The species is shown to be locally common in restricted habitats within its geographic range. A large number of mayfly species in North America are known from fewer locale records and specimens. Paleontological data indicate that Siphlonisca is not represented in the fossil record, the Holarctic family Siphlonuridae sensu stricto is not represented prior to the Ter tiary, and S. aerodromia should not be considered a living fossil. Cladistic data place Siphlonisca as a sister group of the genus Parameletus. The presence of lateral abdominal flanges in the adults are independent adaptations in a number of distantly related mayfly lineages and are related to gill position and type in the larval stage. The presence of laterally expanded abdomens in some Paleo zoic insects does not necessarily denote close relationships with particular lineages of extant may flies. The fact that Siphlonisca is monotypic is not unique among North American mayfly genera. In an appendix to the 1908 Report of the State Entomologist of New York, James G. Needham described the northeastern Nearctic siphlonurid mayfly Siphlonisca aerodromia. The description of the new genus and species was ini tially drafted for a single female adult from Sacandaga Park, Johnstown, New York, collected by C. P. Alexander. -
