  • Description of the third instar larva of Haliplus variomaculatus Brigham & Sanderson with notes on larvae of Nearctic Haliplidae (Coleoptera)
    Tijdschrift voor Entomologie, 2011
    Co-Authors: B. J. Van Vondel
    Abstract:

    The Haliplidae of the Nearctic region comprise 67 species (Majka et al. 2009). Of these, for only 12 species the larvae have been described: Haliplus (Haliplus s.str.) immaculicollis Harris, 1828 (Matheson 1912; Hickman 1930), H. (Haliplus s.str.) apicalis Thomson, 1868 (Bertrand 1942), H. (Liaphlus) fulvus (Fabricius, 1801) (Schiodte, 1864), Peltodytes edentulus (LeConte, 1863) (Matheson 1912; Hickman 1930), P. muticus (LeConte, 1853) (Matheson 1912), P. lengi Roberts, 1913 (Hickman 1930), P. sexmaculatus Roberts, 1913 (Hickman 1930), Apteraliplus parvulus Roberts, 1913 (Leech & Chandler 1956), Brychius hungerfordi Spangler, 1954 (Strand & Spangler 1994) and B. hornii Crotch, 1873 (Mousseau & Roughley 2007). Recently I had the opportunity to study a small collection of Haliplidae from Missouri, results of a project by Megan M. Zeller from the University of Missouri. In that material were three adults of Haliplus variomaculatus Brigham & Sanderson together with a third instar Haliplus larva, all collected from the same locality at two different dates. It is postulated that this larva is indeed the third instar larva of H. variomaculatus. Such finding provided the impetus to this study, which aims at describing for the first time the third instar of Haliplus variomaculatus and at comparing this species with those of other Nearctic Haliplidae known as larvae. General information on the morphology of Haliplidae larvae, specifically for Brychius, Haliplus and Peltodytes are given in van Vondel (1997).

  • Revision of the Haliplidae of the Afrotropical region, including North Africa (Coleoptera)
    Tijdschrift voor Entomologie, 2010
    Co-Authors: B. J. Van Vondel
    Abstract:

    The continent of Africa is in terms of biogeographic regions divided in the Afrotropical region south of the Sahara and the Palaearctic region north of the Sahara with a transition zone in the eastern part. Zimmermann (1924) divided Africa in northern Africa (Morocco, Tunisia, Algeria, Libya, Egypt), western Africa, eastern and southern Africa, Madagascar and recorded 20 species of Haliplidae in total. The last revision of the African Haliplidae dates from 1959 (Guignot 1959). He recorded 29 species. In the World Catalogue of van Vondel (2005b) 37 species are recorded from Africa. The present study aims to describe all species known from Africa, with special attention to the Afrotropical fauna. Based on this study 44 species are now known from Africa, of which nine are new to science (Table 1). Material and methods This study is based on about 1180 specimens preserved in museums and private collections and the author’s own material collected in Benin (van Vondel 2005a). Full label data for all specimens are given and individual identification labels have been placed with all specimens examined. Drawings of genitalia were made using a Swift universal microscope with a camera lucida. The orientation of the genitalia is defined according to van Vondel (1991). Measurements were made by using the ocular-micrometer of a Zeiss stereomicrosope. Morphological terms follow van Vondel (1997) with the exception of the use of “metaventrite”/“metaventral” instead of “metasternum”/“metasternal”. Distribution maps are based on material examined and literature records. Countries are used with their present name and boundaries. Locality names are given according to the labels, but for clarity sometimes the name as Revision of the Haliplidae of the Afrotropical region, including North Africa (Coleoptera)

  • A Review of the Crawling Water Beetles of Mongolia (Coleoptera: Haliplidae)
    Proceedings of the Academy of Natural Sciences of Philadelphia, 2010
    Co-Authors: Andrew E. Z. Short, P.j. Torres, B. J. Van Vondel
    Abstract:

    ABSTRACT. The species of the aquatic beetle family Haliplidae that occur in Mongolia are reviewed. A total of eight species in the genus Haliplus Latreille, 1802 are known from the country, including four here newly recorded: Haliplus basinotatus Zimmerman, 1924, H. fulvus (Fabricius, 1801), H. furcatus Seidlitz, 1887 and H. simplex Clark, 1863. New locality records are provided for H. steppensis Guignot, 1954 and H. sibirieus Motschulsky, 1860. Prior published Mongolian records of H. apicalis Thomson, 1868 were misidentified and this species is not currently known from the country. A key to the species of Haliplidae occurring in Mongolia and surrounding regions is provided.

  • Review of the Haliplidae of Myanmar with description of Haliplus volpei (Coleoptera)
    Tijdschrift voor Entomologie, 2009
    Co-Authors: B. J. Van Vondel
    Abstract:

    The Haliplidae known from Myanmar (=Burma) were recently treated in a wider perspective by van Vondel (1992, 1993) and summarized by van Vondel (2005). A specific list for Myanmar, based on these publications, shows the presence of five species (see below). Recently I had the opportunity to study a number of Haliplidae from Myanmar, which were not recorded by van Vondel (1992, 1993), including a new species. Part of this material was already mentioned in the World Catalogue (van Vondel 2005), but without detailed information. These details will be given in this review. For completeness older records are also included.
