Photos of living specimens First photos ever of a living Baetis tracheatus Daan Drukker Naturalis Biodiversity Center, Department of Terrestrial Zoology, Leiden, South Holland, Netherlands Photos of living mayflies are undoubtedly rare. Relatively speaking that is, because of course there are lots of pictures to be found on the internet. It has been my goal for a while now to photograph as many mayfly species as possible before I collect them for identification. I have focused on the species of The Netherlands and Belgium for a key that I am working on, but I do this everywhere I go, so the rest of Europe is also in my scope. I have almost completed photographing the mayflies that occur in The Netherlands, so it was very special to finally find adults of the enigmatic Baetis tracheatus Keffermüller & Machel, 1967 in the late summer of this year (just in time to use it in my book)! It took me three years and eight visits to finally find them! To my knowledge, these are the first photos of this species of a living individual. The only photos that I am aware of are those of the genitalia from the type series published by Müller-Liebenau (1969). Until now, the only way of knowing what it looked like was to interpret the descriptions and redescriptions (both of which were excellent by the way). I caught ~20 male imagines from their only known locality in The Netherlands. The most important feature that is directly visible is the ochre/rustic colour of the turbinate eyes: just as in the descriptions, but now it is also clear how easy it is to separate them from the – often syntopic – Baetis vernus Curtis 1834. You can compare the photos here below: Fig. 1. First Fig. 2. Baetis photo ever of a vernus, same living imago of date and Baetis tracheatus, location as Fig. 20.ix.2020, The 1. Collected Netherlands.

I make photos of living larvae with just as much enthusiasm as I do with the winged stages, but the advan- tage of larvae is that photos of the larvae in alcohol have often been included in recent publications, and these do not differ much from the shape of a living larva. It is therefore less necessary than making photos of living adults. Making photos of living adults often shows us previously unknown characters. Did you know for example that winged stages of species of the Pseudocentroptilum subgenus of Procloeon almost always have their wings slightly separated? I tested this only on P. (Pseudocentroptilum) pulchrum and P. (P.) pennulatum, so it might be interesting if it is also the case in other species of the (sub)genus. Fig. 3. Larva of Fig. 4.

Volume 23(2) December 2020 The Mayfly Newsletter 3 Tales from the field: My Field Trips in Israel: Not a mistake, just a strange twist of fate Michel Sartori Museum of zoology, Palais de Rumine, Place Riponne 6, 1005 Lausanne, Switzerland. [email protected] I made my first trip to Israel in spring 1990. I met Reuven Ortal (Nature Reserve Authorities, Jerusalem) the year before in Switzer- land, and he convinced me to sample again the main areas where Samocha collected mayflies in the late 60s (Samocha, 1972). This trip was mainly focused on the northern part of the country (Figure 1), and I was assisted by rangers, among them Hillel Glassmann and Avi Reuven. At the end of my stay, around mid-May, I spent a single day in the Dead Sea area with Reuven Ortal, where we collected a strange Lepto- phlebiidae, which turned out to be a new species (Figure 2). For the little history, I put two mature male nymphs in a Thermos flask I designed for rearing mayflies during travelling, and when I ar- rived home two days later, both had emerged, one as M. Sartori subimago, the other as a Fig. 1. Springs of the Dan River, some hundreds of meters from the Lebanon fresh imago (it was a time border, on May 8, 1990. in airplane cabin where you could bring liquids of more than 100 ml!). This prompted me to plan another trip the year after, in order to get more material of this Euthraulus species. Initially, I wanted to go earlier, in February – March, but the Gulf war, especially Operation Desert Storm, and the Scud missiles launched by Iraqi army against Israel, forced me to delay my trip. I arrived for the second time in Israel in spring 1991; I spent some time in the north, and after one week drove by car to En Gedi near the Dead Sea where I spent also one week collecting in M. Sartori Nahal Arugot and surrounding streams. Fig. 2. Nahal Arugot, upstream En Gedi, a stream which brings life into the desert, I published my results one year later (Sartori, 1992); and type locality of Choroterpes (Euth- except for the new species Choroterpes (Euthraulus) or- raulus) ortali Sartori, 1992, as on May 14, tali, I only mentioned for each species the total number 1990. of specimens per stage, and the localities where they were found. This was mainly driven to avoid long lists of material examined… not very clever indeed! No mayfly-focused research was conducted in Israel for the next 25 years. Last year, Zohar Yanai was a postdoc in my museum, and we discussed the opportunity to publish some notes on other mayfly species not mentioned in my 1992 paper. In fact, despite being well known to local ecologists, they had never been published to occur in Israel. This con- cerned two non-baetid species I had collected in 1990 and 1991, and which were collected again more recently by Zohar. When I prepared the list of specimens of Oligoneuriopsis orontensis and Prosopistoma oronti, I realised that there was a mistake on the labels, because, for instance, specimens were mentioned to be collected in the Jordan River, at a place called Dodot (Almagor) Bridge by H.

  • 1.- Heptageniidae, Ephemerellidae, Leptophlebiidae & Palingeniidae
    PRIVATE UBRARV OF WILLIAM L. PETERS Revue suisse Zool. I Tome 99 Fasc. 4 p. 835-858 I Geneve, decembre 1992 Mayflies from Israel (lnsecta; Ephemeroptera) 1.- Heptageniidae, Ephemerellidae, Leptophlebiidae & Palingeniidae * by Michel SARTORI 1 With 45 figures ABSTRACT This paper is the first part of a work dealing with the mayfly fauna of Israel. Eleven species are reported here. The most diversified family is the Heptageniidae with six species belonging to six different genera: Rhithrogena znojkoi (Tshemova), Epeorus zaitzevi Tshemova, Ecdyonurus asiaeminoris Demoulin, Electrogena galileae (Demoulin) (comb. nov.), Afronurus kugleri Demoulin and Heptagenia samochai (Demoulin) (comb. nov.). E. zaitzevi is new for the fauna of Israel. The male of H. samochai is described for the first time and the synonymy with H. lutea Kluge (syn. nov.) is proposed. Eggs of the six species are described and illustrated. Keys are provided for nymphs and adults. Ephemerellidae are represented by a single species, Ephemerella mesoleuca (Brauer). Leptophlebiid species are: Paraleptophlebia submarginata (Stephens), Choroterpes (Ch.) picteti Eaton and Choroterpes (Euthraulus) ortali nov. sp. described at all stages. New features to distinguish the nymphs of the Mediterranean Euthraulus species are provided. One species of Palingeniidae has been found in the collections of Bet Gordon Museum in Deganya: Palingenia orientalis Chopra. The female of this species is described for the first time. P. orientalis disappeared from the investigated area in the early fifties. Some geographical data are given on the distribution of the species inside and outside the investigated area, as well as some ecological observations. For instance, underwater emergence is reported for the first time in the genus Afronurus.

New characters of the thorax, the female gen­ italia, and the egg chorion are used. The Siphlonuroidea consist of a Northern Hemisphere group of families (Siphlonuridae s. str., Dipteromimidae, Ameletidae, Metretopodidae, Acanthametropodidae and Ametropodidae) and a Southern Hemisphere group of families (Oniscigastridae, Nesameletidae, Rallidentidae, and Ameletopsidae). The family Dipteromimidae and the subfamily Parameletinae are established. The synonymy of lsonychia polita and Acanthametropus nikolskyi is documented. Fossil Siphlonuroidea of uncertain family status are included. The rel ation ships between the families are di s­ cussed. Key words: eggs. Ephemeroptera, morphology, phylogeny, Siphlonuridae, Siphlonuroidea, systematics. INTRODUCTION The taxonomy and the phylogeny of Siphlonuroidea or Siphlonuridae sensu Lato are subject to different opinions. The authors that have worked on the rank and composition of this taxon (EDMUNDS, 1972; MCCAFFERTY & EDMUNDS, 1979; LANDA & SOLDAN, 1985; M CCAFFERTY, 1991; TOMKA & ELPERS, 1991; KLUGE, in press, and others) have used the taxon Siphlonuridae in different senses. These dif­ ferences are based on (1) the importance attached to adult versus larval characters, (2) the interpretation of characters as being synapomorphic or symplesiomorphic, (3) the paraphyletic nature of the group, and ( 4) inadequate diagnoses of many tax a.

DISTRIBUTION: MoDNR Intranet ESP SOP Coordinator RECERTIFICATION RECORD: Date Reviewed Initials Page 1 of 30 MDNR-WQMS-209 Effective Date: 05/31/05 Page 2 of 30 1.0 GENERAL OVERVIEW 1.1 This Standard Operating Procedure (SOP) is designed to be used as a reference by biologists who analyze aquatic macroinvertebrate samples from Missouri. Its purpose is to establish consistent levels of taxonomic resolution among agency, academic and other biologists. The information in this SOP has been established by researching current taxonomic literature. It should assist an experienced aquatic biologist to identify organisms from aquatic surveys to a consistent and reliable level. The criteria used to set the level of taxonomy beyond the genus level are the systematic treatment of the genus by a professional taxonomist and the availability of a published key. 1.2 The consistency in macroinvertebrate identification allowed by this document is important regardless of whether one person is conducting an aquatic survey over a period of time or multiple investigators wish to compare results. It is especially important to provide guidance on the level of taxonomic identification when calculating metrics that depend upon the number of taxa.

SGMA seeks to achieve sustainability, which is defined as the absence of several undesirable results, including “depletions of interconnected surface water that have significant and unreasonable adverse impacts on beneficial users of surface water” (Water Code §10721). The Nature Conservancy (TNC) is a science-based, nonprofit organization with a mission to conserve the lands and waters on which all life depends. Like humans, plants and animals often rely on groundwater for survival, which is why TNC helped develop, and is now helping to implement, SGMA. Earlier this year, we launched the Groundwater Resource Hub, which is an online resource intended to help make it easier and cheaper to address environmental requirements under SGMA. As a first step in addressing when depletions might have an adverse impact, The Nature Conservancy recommends identifying the beneficial users of surface water, which include environmental users. This is a critical step, as it is impossible to define “significant and unreasonable adverse impacts” without knowing what is being impacted. To make this easy, we are providing this letter and the accompanying documents as the best available science on the freshwater species within the boundary of your groundwater sustainability agency (GSA).

ZooKeys 1002: 1–114. https://doi. org/10.3897/zookeys.1002.58017 Abstract Material collected between 1994 and 2020 in the Philippines, covering most main islands like Luzon, Mindoro, Palawan, Negros, Cebu, Leyte, and Mindanao and some smaller islands, substantially increased our knowledge of Labiobaetis Novikova & Kluge in this archipelago. Only three species were previously reported: L. molawinensis (Müller-Liebenau, 1982) and L. sumigarensis (Müller-Liebenau, 1982) from larvae and L. boettgeri (Ulmer, 1924) from adults. Eighteen new species have been identified using a combination of morphology and genetic distance (COI, Kimura 2-parameter). They are described and illustrated based on their larvae and a key to all species in the Philippines is provided.

African Invertebrates 62(1): 231–255. https://doi.org/10.3897/AfrInvertebr.62.62029 Abstract Material collected between 2017 and 2019 in Ethiopia in the Awash River catchment substantially in- creased our knowledge of Labiobaetis Novikova & Kluge in this country. Four species were previously reported based on ecological investigations of Ethiopian rivers: L. glaucus (Agnew, 1961), L. latus (Agnew, 1961), L. vinosus (Barnard, 1932) and L. bellus (Barnard, 1932). We have identified six different species using a combination of morphology and genetic distance (COI, Kimura 2-parameter). Two of them, L. alahmadii Gattolliat & Al Dhafer, 2018 and L. potamoticus Gattolliat & Al Dhafer, 2018 were previ- ously assumed to be endemic to the Arabian Peninsula. The status ofL. bellus is discussed and remains unresolved. One species is new to science; it is described and illustrated based on its nymphs. A key to the nymphs of all Ethiopian species is provided.
