Silva-Neto Received: February 19, 2021. Accepted: March 02, 2021. Published: March 12, 2021. Abstract. Stratiomyidae is a diverse family of orthorrhaphous Brachycera. It exhibits great morphological variation and is the largest family in the infraorder Stratiomyomorpha. The present communication deals with the recording of five species of soldier flies from Oman, of which Odontomyia angulata (Panzer, 1798), Odontomyia xanthopus Bezzi, 1906, Oplodontha pulchriceps Loew, 1858, Nemotelus (Nemotelus) niloticus Olivier, 1811 from northern Oman and an unidentified specimen of Tinda Walker, 1859 from southern Oman, in Dhofar region. Keywords: Oman insects, Odontomyia, Oplodontha, Nemotelus, Tinda. Soldier flies (Stratiomyidae Latreille, 1802) are a worldwide group In total eight specimens of Stratiomyidae were collected. Among of flies of the suborder Brachycera, with circa 2700 described species them, five species of four genera and three subfamilies are new records within 12 subfamilies (Hauser 2009). The size of these flies varies from for Oman: Odontomyia angulata (Panzer, 1798), O. xanthopus Bezzi, 2-20 mm, and they have different body colors, some are wasp mimics 1906, Oplodontha pulchriceps Loew, 1858, Nemotelus (Nemotelus) marked with different color patterns such as black and yellow, green, and niloticus Olivier, 1811 and an unidentified specimen of Tinda Walker, sometimes metallic (Woodley 2001; Hauser 2009; Hassan et al.

McFadden ^ The Stratiomyidae or soldier flies are represented in America north of Mexico by approximately 237 species distributed through 37 genera. Prior to this study, larvae have been described for only 21 species representmg 15 genera. In addition to the lack of adequate descriptions and keys, classification has seldom been attempted and a phylogenetic treatment of the larvae has never been presented. The present study has been undertaken with several goals in mind: to rear and describe (1) as many species as possible; (2) to redescribe all previously described larvae of North American species; and (3), on the basis of larval characters, to attempt to define various taxo- nomic units and show phylogenetic relationships withm the family and between it and other closely related familes. Any attempt to establish subfamilial and generic lunits must be regarded as tentative. This is especially true in the present study since larvae of so many species of Stratiomyidae remain unknown. Undoubtably, as more species are reared, changes mil have to be made in keys and definitions of taxa. The keys have been prepared chiefly for identification of last mstar larvae. If earher mstars are known, they either have been 1 Modified from a Ph. D. dissertation submitted to the University of Alberta E(hnonton, Canada. ' 2 Entomology Research Division, U.S. Dept.

PREFACE Eight years ago the author of the present work published a small volume in which he attempted to tabulate the families and more important genera of the diptera of the United States. From the use that has been made of that work by etitomological students, he has been encouraged to believe that the labor of its preparation was not in vain. The extra- ordinary activity in the investigation of our dipterological fauna within the past few years has, however, largely destroy- ed its usefulness, and it is hoped that this new edition, or rather this new work, will prove as serviceable as has been the former one. In the present work there has been an at- tempt to include all the genera now known from north of South America. While the Central and West Indian faunas are preeminently of the South American type, there are doubt- less many forms occurring in tlie southern states that are at present known only from more southern regions. In the preparation of the work the author has been aided by the examination, so far as he was able, of extensive col- lections from the West Indies and Central America submitted to him for study by Dr.

    F. Christian Thompson Neal L. Evenhuis and Curtis W. Sabrosky Bibliography of the Family-Group Names of Diptera Bibliography Thompson, F. C, Evenhuis, N. L. & Sabrosky, C. W. The following bibliography gives full references to 2,982 works cited in the catalog as well as additional ones cited within the bibliography. A concerted effort was made to examine as many of the cited references as possible in order to ensure accurate citation of authorship, date, title, and pagination. References are listed alphabetically by author and chronologically for multiple articles with the same authorship. In cases where more than one article was published by an author(s) in a particular year, a suffix letter follows the year (letters are listed alphabetically according to publication chronology). Authors' names: Names of authors are cited in the bibliography the same as they are in the text for proper association of literature citations with entries in the catalog. Because of the differing treatments of names, especially those containing articles such as "de," "del," "van," "Le," etc., these names are cross-indexed in the bibliography under the various ways in which they may be treated elsewhere. For Russian and other names in Cyrillic and other non-Latin character sets, we follow the spelling used by the authors themselves. Dates of publication: Dating of these works was obtained through various methods in order to obtain as accurate a date of publication as possible for purposes of priority in nomenclature. Dates found in the original works or by outside evidence are placed in brackets after the literature citation.

  • Arthropods Associated with Above-Ground Portions of the Invasive Tree, Melaleuca Quinquenervia, in South Florida, Usa
    300 Florida Entomologist 86(3) September 2003 ARTHROPODS ASSOCIATED WITH ABOVE-GROUND PORTIONS OF THE INVASIVE TREE, MELALEUCA QUINQUENERVIA, IN SOUTH FLORIDA, USA SHERYL L. COSTELLO, PAUL D. PRATT, MIN B. RAYAMAJHI AND TED D. CENTER USDA-ARS, Invasive Plant Research Laboratory, 3205 College Ave., Ft. Lauderdale, FL 33314 ABSTRACT Melaleuca quinquenervia (Cav.) S. T. Blake, the broad-leaved paperbark tree, has invaded ca. 202,000 ha in Florida, including portions of the Everglades National Park. We performed prerelease surveys in south Florida to determine if native or accidentally introduced arthro- pods exploit this invasive plant species and assess the potential for higher trophic levels to interfere with the establishment and success of future biological control agents. Herein we quantify the abundance of arthropods present on the above-ground portions of saplings and small M. quinquenervia trees at four sites. Only eight of the 328 arthropods collected were observed feeding on M. quinquenervia. Among the arthropods collected in the plants adven- tive range, 19 species are agricultural or horticultural pests. The high percentage of rare species (72.0%), presumed to be transient or merely resting on the foliage, and the paucity of species observed feeding on the weed, suggests that future biological control agents will face little if any competition from pre-existing plant-feeding arthropods. Key Words: Paperbark tree, arthropod abundance, Oxyops vitiosa, weed biological control RESUMEN Melaleuca quinquenervia (Cav.) S. T. Blake ha invadido ca. 202,000 ha en la Florida, inclu- yendo unas porciones del Parque Nacional de los Everglades. Nosotros realizamos sondeos preliminares en el sur de la Florida para determinar si los artópodos nativos o accidental- mente introducidos explotan esta especie de planta invasora y evaluar el potencial de los ni- veles tróficos superiores para interferir con el establecimento y éxito de futuros agentes de control biológico.

  • Soldierflies in VC55
    LEICESTERSHIRE ENTOMOLOGICAL SOCIETY Provisional status of Soldierflies (Stratiomyidae) in VC55 Ray Morris Odontomyia argentata (Graham Calow) LESOPS 33 (April 2017) ISSN 0957 - 1019 16 Hinckley Road, Dadlington CV13 6HU [email protected] LESOPS 33 (2017) Soldierflies 2 Introduction The flies (Diptera) are often considered to be difficult for the amateur to study. Perhaps the main exception is the Syrphidae (hoverflies) as many are easily recognised from their behaviour, bright coloration and abdominal markings. Even so care has to be taken with many of the species. The flies that constitute the “Larger Brachycera” share two common wing features: anal veins that converge (Figure 1a) and veins that fan out to the edge of the wing (Figure 1b). Among this grouping are the Stratiomyidae (soldierflies) which usually can be readily identified as a family by their well-defined discal cell (Figure 1c) although some, e.g. Pachygaster, may not show this so well. 1c: Small central well- defined discal cell 1a: Anal veins converging towards wing edge 1b: Veins fanning out towards wing edge Figure 1: Typical wing of Stratiomyidae Availability of an excellent user-friendly key (Stubbs & Drake, 2014) enables identification of soldierflies to be achieved relatively easily although some sort of magnification is recommended to aid recognition of diagnostic characters. Most importantly, the soldierflies are a small group and should appeal to those who wish to extend their entomological interest without being burdened by a large number of species to come to terms with. In Britain there are 48 species regarded as being resident and of those 33 have been recorded in VC55 (Leicestershire & Rutland) to the end of 2016.
