  • Trichomycetes from Lentic and Lotic Aquatic Habitats in Ontario, Canada
    1449 Trichomycetes from lentic and lotic aquatic habitats in Ontario, Canada D.B. Strongman and Merlin M. White Abstract: Fungi and protists make up an ecological group, trichomycetes, that inhabit the guts of invertebrates, mostly aquatic insects. Trichomycetes are reported herein from arthropods collected in lotic habitats (fast flowing streams) and lentic environments (ponds, ditches, seeps, and lakes) from 11 sites in Algonquin Park and 6 other sites in Ontario, Can- ada. Thirty-two trichomycete species were recovered, including 7 new species: Legeriomyces algonquinensis, Legeriosi- milis leptocerci, Legeriosimilis whitneyi, and Paramoebidium umbonatum are described from mayfly nymphs (Ephemeroptera); Pennella digitata and Glotzia incilis from black fly and midge larvae (Diptera), respectively; and Arun- dinula opeongoensis from a crayfish (Crustacea). Legeriomyces rarus Lichtw. & M.C. Williams and Stachylina penetralis Lichtw. are new North American records, and seven species are documented for the first time in Canada. More common and widely distributed trichomycete species such as Harpella melusinae Le´ger & Duboscq and Smittium culicis Manier, were also recovered. Most previous studies on trichomycetes have been done primarily in lotic environments but clearly lentic systems (e.g., ponds and lakes) harbour diverse arthropod communities and further exploration of these habitats will continue to increase our knowledge of trichomycete diversity. Key words: Amoebidiales, Eccrinales, Harpellales, insect fungal endobionts, symbiotic protista. Re´sume´ : Les champignons et les protistes comportent un groupe e´cologique, les trichomyce`tes, qui habitent les intestins de la plupart des insectes aquatiques. Les auteurs rapportent des ttrichomyce`tes provenant d’arthropodes vivants dans des habitats lotiques (cours d’eau rapides) et des environnements lentiques (e´tangs, fosse´s, suintement et lacs) re´colte´s sur 11 sites dans le parc Algonquin et six autres sites en Ontario, au Canada.

Zemřel po krátké nemoci ve věku nedožitých 67 let. Tomáše Soldána zajímala zoologie, respekti- ve entomologie, již od dětství. Po absolvování Gymnázia Botičská směřovaly jeho kroky na Přírodovědeckou fakultu Univerzity Kar- lovy. V té době zde působili vynikající učitelé a entomologové, jako Karel Hůrka, Milan Chvála nebo Pavel Štys. Možná právě jejich přístup k vedení studentů a skvělé přednášky Pavla Štyse o morfologii hmyzu ovlivnily i bu- doucí směřování Tomáše Soldána. Po ukončení studia a absolvování povinné vojenské služby nastoupil Tomáš v létě 1975 na Oddělení morfologie hmyzu Entomolo- gického ústavu ČSAV, který v té době sídlil ve Viničné ulici v Praze.

  • Filter-Feeding Habits of the Larvae of Anthopotamus \(Ephemeroptera
    Annls Limnol. 28 (1) 1992 : 27-34 Filter-feeding habits of the larvae of Anthopotamus (Ephemeroptera : Potamanthidae) W.P. McCaffertyl Y.J. Bae1 Keywords : Ephemeroptera, Potamanthidae, Anthopotamus, filter feeding, behavior, morphology, detritus. A field and laboratory investigation of the food and feeding behavior of larvae of the potamanthid mayfly Anthopo­ tamus verticis (Say) was conducted from 1989 to 1991 on a population from the Tippecanoe River, Indiana (USA). Gut content analyses indicated that all size classes of larvae are detritivores, with over 95 % of food consisting of fine detrital particles. Videomacroscopy indicated that all size classes of larvae are filter feeders, able to utilize both active deposit filter feeding and passive seston filter feeding cycles in their interstitial microhabitat. Deposit filter feeding initially incor­ porates the removal of loosely deposited detritus with the forelegs. Seston filter feeding initially incorporates filtering by long setae on the forelegs and palps. Mandibular tusks are used to help remove detritus from the foreleg setae. A SEM examination of filtering setae indicated they are hairlike and bipectinate, being equipped with lateral rows of setu- les. The results show that previous assumptions that potamanthid larvae were collector/gatherers are erroneous. The results are applicable to congeners, and all potamanthids, including Palearctic and Oriental elements, are hypothesized to be filter feeders, differing only in some details of behavior.

  • A Comparative Study of Spermatozoa of Some Central European
    Acta entomologica bohemoslovaca, 76: 223-230, 1979 ISSN 0001 - 5601 A comparative study of spermatozoa of some Central European Ephemeroptera TOMAS SOLDAN Department of Developmental Morphology, Institute of Entomology, Czechoslovak Academy of Sciences, Praha Morphology, smears, staining, measurements, light microscopy, 25 genera Abstract. The spermatozoa of species from 25 genera (11 families, 51 species) representative of Central European mayflies were investigated. Squashes and smears of seminal vesicles of adult testes fixed in osmium tetroxide vapours were stained by Pappenheim's method. There are four principal groups of spermatozoa: (i) rod-shaped spermatozoa with relatively short head ( 3-8 µm in length) and with flagellum, these subdivide into two distinct types: smaller, well stainable, rod-shaped spermatozoa (about 75-90%) and large, less well stainable, usually spindle-shaped spermatozoa (about 25-10%) (Siphlonuridae, Ephoron, Ephemera, Potamanthus); (ii) rod-shaped, elongated spermatozoa with relatively long (8-20 µm in length) head and with flagellum similar in shape, these also differentiated into two staining types (Baetidae); (iii) rod-shaped spermatozoa with shorter or longer head and well developed flagellum equal in both length and shape, these all of well staining type (Heptageniidae, Arthroplea, Ephemerella, Caenidae); (iv) rounded spermatozoa differentiated into two staining types as in groups (i) and (ii) but flagellum not discernible under light microscope (Leptophlebiidae). The arrangement of the morphological characters of mayfly spermatozoa is supposed to be related to the main phylogenetic trends within the order. Our knowledge of mayfly eggs and mipecially of chorion structure, micro­ pyle and sperm guide is n hctivcly very extensive. The eggs of most of the European gcnerr~ were c:('alt with by DEGRANGE ( 19CO) who also studied the fecundity offomaleG.

Flowers and Hilsenhoff: Heptageniidae (Ephemeroptera) of Wisconsin THE GREAT LAKES ENTOMOLOGIST HEPTAGENllDAE (EPHEMEROPTERA) OF WISCONSIN' R. Wills ~lowers~and William L. ~ilsenhoffj Heptageniidae are one of the most abundant and widespread components of Wisconsin's aquatic insect fauna. In almost any stream with a firm substrate and free of gross pollution, the flattened nymphs can be found hiding in crevasses and under rocks, or clinging to submerged wood. Adults and nymphs are easily distinguished from mayflies of other families, nymphs by their dorsoventrally flattened head and dorsal eyes, and adults by their 5-segmented tarsi and complete wing veination. This paper presents our knowledge to date of Heptageniidae in Wisconsin. Early studies of Heptageniidae and other mayflies are summarized by Burks (1953). The original classification of Heptageniidae was based on the adult male, particularly length ratios of fore tarsal segments.

Department of Biology. Bloomington, Indiana 47405. Jacobus and McCafferty (2001b) listed 173 E. pleuralis, in that the posterior margin of the species of mayflies from New York, including 42 subgenital plate is distinctly indented. Epeorus new state species records, of which 170 were pleuralis is known to show morphological considered valid taxa. Herein, we augment that variability, but the population that was list with nine new state species records (indicated misidentified as E. frisoni may require further by an asterisk, "*") and new collection data for investigation (S. Burian, pers. comm.). species seldomly reported from the state. We also Heptagenia marginalis Banks was reported as a note recent changes to the taxonomy of New York new state record by Jacobus and McCafferty Ephemeroptera and note other necessary (2001b), but in fact Traver (1935) reported it emendations to the list of species records. previously. Taxa impacted by nomenclature changes since Thus, the number of presumably correctly Jacobus and McCafferty’s (2001b) list include all identified and valid nominal species reported from species formerly included in Stenonema Traver, New York before this study was 167. We note excluding S. femoratum (Say), that are now part of that reports of Centroptilum triangulifer the genus Maccaffertium Bednarik (McDunnough) should be considered tentative as (Heptageniidae); Heterocloeon amplum (Traver), they might represent that species, C.
