Descriptions Many Specimens by the Collecting of Syrphid Especially STUDIES ON THE FAUNA OF SURINAME AND OTHER GUYANAS: No. 35. Syrphidae from Suriname Additional records and descriptions by P.H. van Doesburg Sr. (Baarn, Nederland) This intended study is as a continuation of the “Preliminary List of Syrphidae” published in volume V of this journal. As no further flies of the other Guianas has information on the Syrphid come to these countries can be left out of consideration here. my knowledge Since the dispatch of the manuscript of the “Preliminary List” to the editors several species not yet known from Suriname have been received. Once of these flies collected again a large part were by my D. son Drs. P. H. van Doesburg junior. Dr. C. Geijskes, Director of the Suriname Museum, Paramaribo, has also sent me big lots of To Syrphids in which many interesting species were represented. I to heartfelt Moreover both gentlemen wish express appreciation. for his my son deserves special thanks interrupting own demanding work to produce the beautiful, exact illustrations. Many specimens sent by Dr. GEIJSKES have been collected by the useful use of a “Malaise trap”.

    ROTHERAY et al.: 385-389 Studia dipterologica 7 (2000) Heft 2 • ISSN 0945-3954 Remarkable aquatic predators in the genus Ocyptamus (Diptera, Syrphidae) [Bemerkenswerte aquatische Pradatoren in der Gattung Ocyptamus (Diptera, Syrphidae)] by Graham E. ROTHERAY, Manuel ZUMBADO, E. Geoffrey HANCOCK and F. Christian THOMPSON Edinburgh (United Kingdom) Santo Domingo (Costa Rica) Glasgow (United Kingdom) Washington (USA) Abstract Third-stage larvae, puparia and adults are described for two species of Ocyptamus MACQUART and new synonyms are proposed. The larvae were found in water pockets within epiphytic Bromeliaceae in Costa Rica. They attacked a wide taxonomic range of insect larvae that char- acteristically co-occur in these phytotelmata, apparently subduing prey with venom and suck- ing out the internal contents. They possess a number of morphological and behavioural fea- tures not known in other predatory syrphids. These features include an enlarged and flattened anal end bearing a sucker, elongate posterior breathing tubes with vertically inclined spiracu- lar plates, and patches of needle-like spicules on the underside of the thorax. Although only two species were reared, larvae of 6 other species were discovered, which suggest that many more species occur in bromeliads. Key words Predator, phytotelmata, bromeliads, anal sucker, venom Zusammenfassung Von zwei Arten der Gattung Ocyptamus MACQUART werden die dritten Larvenstadien, die Puparien und die Imagines beschrieben und charakterisiert sowie neue Synonyme festgelegt. Die Larven wurden in Phytothelmata von epiphytischen Bromelien in Kostarika gefunden. Sie attackieren ein weites Spektrum von Insektenlarven, die hier gemeinsam mit den Syrphiden- larven leben. Offensichtlich lahmen sie die Beute mittels eines Giftes und saugen dann den deren Korperinhalt aus.

  • Diptera: Syrphidae) with Notes on the Placement of the Subfamily by F
    A NEW GENUS OF MICRODONTINE FLIES (DIPTERA: SYRPHIDAE) WITH NOTES ON THE PLACEMENT OF THE SUBFAMILY BY F. CHRISTIAN THOMPSON I discovered the following new genus of Syrphidae while reviewing the Neotropical Microdontinae. I had planned to put aside its de- scription until my study of the subfamily was finished. However, publication of a second species, assignable to it by van Doesburg (1966) has necessitated publishing a name now for this genus so that it can be included in the Catalog of South American Diptera. Paragodon, new genus Very small (4-5 mm.) microdontine flies. Face simple (slightly produced in paragoides); cheeks absent, eyes bordering on the oral opening; eyes dichoptic in both sexes; occiput evenly developed. An- tennae short, about one-half as long as face; aristae short and thick- ened. Thorax about as long as broad; pleura bare except mesopleura pilose and meta.pleura with microscopic, pile; scutellum without apical spines and fringe; metasterna undeveloped and bare; metathoracic spiracles without hair fringes. Legs simple, with no basal setal patches on the femora and with cicatrices only on the hind femora. Vings without the spurious vein, with all apical crossveins straight. Abdomen oval, lateral margins slightly emarginate and rolled under ventrally, with ISt sternite bare and st spiracles without hair fringes. Genitalia simple; ejaculatory apodeme simple, apical por- tion not triangularly flared; ejaculato.ry sac not sclerotized; ejacula- tory process single, short, not posteriorly fused to ejaculatory hood; ejaculatory hood with anterior ventral portion elongate; sustentacu- lar apodeme present, double, fused anteriorly to base of ejaculatory Contribution no. 1392 from the Systematics and Morphology Research Laboratory, Department of Entomology, University of Massachusetts.

Author: Reemer, Menno Title: Unravelling a hotchpotch : phylogeny and classification of the Microdontinae (Diptera: Syrphidae) Issue Date: 2012-03-13 7 Review and phylogenetic evaluation of associations between Microdontinae (Diptera: Syrphidae) and ants (Hymeno- ptera: Formicidae) Abstract. The immature stages of hoverflies of the subfamily Microdontinae (Diptera: Syrphidae) are known to develop in ants nests, as predators of the ant brood. The present paper reviews published and unpublished records of associations of Microdontinae with ants, in order to discuss the following questions: 1. are alle Microdontinae associated with ants?; 2. are Microdontinae associated with all ants?; 3. are particular clades of Microdontinae associated with particular clades of ants? A total number of 103 records of associations between the groups are evaluated, relating to 42 species of Microdontinae belonging to 14 (sub)genera, and to 58 species of ants belonging to 23 genera and four subfamilies. Known associations are mapped onto the most recent phylogenetic hypotheses of both ants and Microdontinae. The taxa of Microdontinae found in association with ants appear to occur scattered throughout their phylogenetic tree, and one of the supposedly most basal taxa (Mixogaster) is known to be associated with ants. This suggests that associations with ants evolved early in the history of the subfamily, and have remained a predominant feature of their lifestyle. When considering the phylogeny of ants, associations with Microdontinae are only known from the subfamilies Dolichoderinae, Formicinae, Myrmicinae and Pseudomyrmecinae, which are all part of the the so-called ‘formicoid’ clade.

  • HOVERFLY NEWSLETTER Dipterists
    HOVERFLY NUMBER 41 NEWSLETTER SPRING 2006 Dipterists Forum ISSN 1358-5029 As a new season begins, no doubt we are all hoping for a more productive recording year than we have had in the last three or so. Despite the frustration of recent seasons it is clear that national and international study of hoverflies is in good health, as witnessed by the success of the Leiden symposium and the Recording Scheme’s report (though the conundrum of the decline in UK records of difficult species is mystifying). New readers may wonder why the list of literature references from page 15 onwards covers publications for the year 2000 only. The reason for this is that for several issues nobody was available to compile these lists. Roger Morris kindly agreed to take on this task and to catch up for the missing years. Each newsletter for the present will include a list covering one complete year of the backlog, and since there are two newsletters per year the backlog will gradually be eliminated. Once again I thank all contributors and I welcome articles for future newsletters; these may be sent as email attachments, typed hard copy, manuscript or even dictated by phone, if you wish. Please do not forget the “Interesting Recent Records” feature, which is rather sparse in this issue. Copy for Hoverfly Newsletter No. 42 (which is expected to be issued with the Autumn 2006 Dipterists Forum Bulletin) should be sent to me: David Iliff, Green Willows, Station Road, Woodmancote, Cheltenham, Glos, GL52 9HN, (telephone 01242 674398), email: [email protected], to reach me by 20 June 2006.

Imada Hawaii Biological Survey Bernice Pauahi Bishop Museum Honolulu, Hawai‘i 96817, USA Final Report prepared for the U.S. Navy Contribution No. 2021-003 to the Hawaii Biological Survey EXECUTIVE SUMMARY The Bishop Museum was contracted by the U.S. Navy to conduct surveys of terrestrial arthropods in Hālona Valley, Naval Magazine Lualualei Annex, in order to assess the status of populations of three groups of insects, including species at risk in those groups: picture-winged Drosophila (Diptera; flies), Hylaeus spp. (Hymenoptera; bees), and Rhyncogonus welchii (Coleoptera; weevils). The first complete survey of Lualualei for terrestrial arthropods was made by Bishop Museum in 1997. Since then, the Bishop Museum has conducted surveys in Hālona Valley in 2015, 2016–2017, 2017, 2018, 2019, and 2020. The current survey was conducted from August 2020 through November 2020, comprising a total of 12 trips; using yellow water pan traps, pitfall traps, hand collecting, aerial net collecting, observations, vegetation beating, and a Malaise trap. The area chosen for study was a Sapindus oahuensis grove on a southeastern slope of mid-Hālona Valley. The area had potential for all three groups of arthropods to be present, especially the Rhyncogonus weevil, which has previously been found in association with Sapindus trees. Trapped and collected insects were taken back to the Bishop Museum for sorting, identification, data entry, and storage and preservation. The results of the surveys proved negative for any of the target groups.

Indigenous syrphid larvae attack the lettuce aphid and are believed to be effective in the Available online xxxx management of this invasive pest, although there have been no studies on the capacity of the syrphid lar- vae to kill and consume lettuce aphids. We focused on four syrphid species commonly found in central Keywords: coast lettuce fields: Allograpta obliqua (Say), Eupeodes fumipennis (Thomson), Sphaerophoria sulphuripes Biological control (Thomson), and Toxomerus marginatus (Say). Laboratory feeding experiments were conducted to estimate Aphididae the development times of all juvenile stages, the daily growth rate of larvae, the number of third instar Syrphidae Predation potential aphids killed, the aphid biomass killed, and the aphid biomass consumed as measures of predator perfor- Lettuce mance. Results show that during larval development E. fumipennis killed the most third-instar aphids (507 aphids, 88 mg biomass killed) and reached the largest size, followed by A. obliqua (228 aphids, 39 mg killed), S.
