Reticulitermes nelsonae, a new species of subterranean termite (Isoptera, Rhinotermitidae) is described from Sapelo Island, Georgia, United States of America, with specimens also found in North Carolina and Florida. The adult and soldier castes are described and illustrated to distinguish R. nelsonae from the four described Reticulitermes spp. known to occur in the southeastern United States.
Extreme economic effects globally of various populations of the whitefly Bemisia tabaci (Gennadius)
(Hemiptera: Aleyrodidae) led to an in depth study of the morphology of that species as well as that of
numerous other species of whiteflies in the genus Bemisia Quaintance and Baker and other similar appearing
species. The data collected are presented here as illustrations of the puparia (fourth instar nymphal stages)
and discussions of morphology as it relates to species and generic separations within this closely knit group
of insects. A brief history of the pest outbreaks of B. tabaci is given and an overview of the important
morphological characteristics of aleyrodine whiteflies is provided. Each of the eighty illustrations is
accompanied by a discussion of the more important aspects of morphology.
Australia is predicted to have a high number of currently undescribed ostracod taxa. The genus Bennelongia De Deckker & McKenzie, 1981 (Crustacea, Ostracoda) occurs in Australia and New Zealand, and has recently shown potential for high speciosity, after the description of nine new species from Western Australia. Here, we focus on Bennelongia from eastern Australia, with the objectives of exploring likely habitats for undiscovered species, genetically characterising published morphological species and scanning classical species for cryptic diversity. Two traditional (morphological) species are confi rmed to be valid using molecular evidence (B. harpago De Deckker & McKenzie, 1981 and B. pinpi De Deckker, 1981), while three new species are described using both morphological and molecular evidence. Two of the new species belong to the B. barangaroo lineage (B. dedeckkeri sp. nov. and B. mckenziei sp. nov.), while the third is a member of the B. nimala lineage (B. regina sp. nov.). Another species was found to be genetically distinct, but is not formally described here owing to a lack of distinguishing morphological features from the existing species B. cuensis Martens et al., 2012. Trends in diversity and radiation of the genus are discussed, as well as implications these results have for the conservation of temporary pool microfauna and our understanding of Bennelongia’s evolutionary origin.
A revision of the known African species of Psammoecus is given, including redescriptions and illustrations of diagnostic characters. Extensive material from the Musée royal de l’Afrique centrale (Tervuren) is studied. Two new species are described: Psammoecus leleupi sp. nov., and Ps. luchti sp. nov. Four specific names are synonymized: Psammoecus excellens Grouvelle, 1908 = Ps. trimaculatus Motschulsky, 1858; Ps. alluaudi Grouvelle, 1912 = Ps. trimaculatus Motschulsky, 1858; Ps. longulus Grouvelle, 1878 = Ps. longicornis Schaufuss, 1872; Ps. nitescens Grouvelle, 1914 = Ps. laetulus Grouvelle, 1914. A key to the African species is provided.
An account of the taxonomic position of the genus Bracon Fabricius, 1804 is presented. In his monograph Wesmael (1838: 7-58) made a survey of 48 nominal species of Bracon occurring in Belgium. Out of the 48 species thirty-seven were described by Wesmael himself as new species, eleven more species had previously been described by Fabricius (three species), Nees (seven species) and Spinola (one species). The Bracon material studied by Wesmael is deposited in the Royal Belgian Institute of Natural Sciences, Brussels. Type (holo-, lecto-, paralectotype) designations are made for Wesmael’s species and neotype designations for Nees sensu Wesmael’s species. Redescriptions, comments on distributions and their taxonomic positions are presented. Palpibracon subgen. nov. is established (type species Bracon delibator Haliday, 1833) for fi ve Bracon species with long maxillary palpi in the Holarctic (four species) and Ethiopian Region (one species). The following fifteen Bracon species names proved to be junior synonyms (valid names in italics): B. dichromus Wesmael, 1838 = B. carpaticus Niezabitowski, 1910 syn. nov.; B. erraticus Wesmael, 1838 = B. bellicosus Papp, 1971 syn. nov., = B. exarator Marshall, 1885 syn. nov., = B. praetermissus Marshall, 1885 syn. nov., B. vectensis Marshall, 1885 syn. nov.; B. fuscicornis Wesmael, 1838 = B. levicarinatus Niezabitowski, 1910 syn. nov.; B. immutator Nees, 1834 = B. breviusculus Wesmael, 1838 syn. nov.; B. intercessor Nees, 1834 = B. laetus Wesmael, 1838 syn. nov.; B. larvicida Wesmael, 1838 = B. crassiusculus Szépligeti, 1901 syn. nov.; B. longicollis Wesmael, 1838 = B. subcylindricus Wesmael, 1838 syn. nov.; B. megapterus Wesmael, 1838 = B. biimpressus Telenga, 1936 syn. nov.; B. nigratus Wesmael, 1838 = B. orbicularis Niezabitowski, 1910 syn. nov.; B. osculator Nees, 1811 = B. coniferarum Fahringer, 1927 (Schmiedeknecht in litt.) syn. nov.; B. picticornis Wesmael, 1838 = B. vitripennis Ratzeburg, 1852 syn. nov.; B. titubatus Wesmael, 1838 = B. fuscipennis Wesmael, 1838 syn. nov. The species Bracon (Lucobracon) turolus Papp, 1984 is revalidated (suppressed under the name B. (Glabrobracon) nigriventris Wesmael, 1838 by Tobias & Belokobylskij 2000: 162). A historic discussion of the subgeneric division of the Bracon species is given.
The Caribbean Islands (or the West Indies) are recognized as one of the leading global biodiversity hot
spots. This is based on data on species, genus, and family diversity for vascular plants and non-marine vertebrates. This
paper presents data on genus level endemicity for the most speciose (but less well publicised) group of terrestrial
animals: the beetles, with 205 genera (in 25 families) now recognized as being endemic (restricted) to the West Indies.
The predominant families with endemic genera are Cerambycidae (41), Chrysomelidae (28), Curculionidae (26), and
Staphylinidae (25). This high level of beetle generic endemicity can be extrapolated to suggest that a total of about
700 genera of all insects could be endemic to the West Indies. This far surpasses the total of 269 endemic genera of all
plants and non-marine vertebrates, and reinforces the biodiversity richness of the insect fauna of the West Indies.
A taxonomic review of the ancora species group of Graphipterus Latreille (Coleoptera: Carabidae)
(2012)
The taxonomy of the ancora species group of Graphipterus Latreille (Coleoptera: Carabidae) is reviewed and seven species are recognized, all from southern Africa: Graphipterus ancora Dejean, Graphipterus cordiger Dejean, Graphipterus distinctus Péringuey (new status), Graphipterus fasciatus Chaudoir, Graphipterus fritschi Chaudoir, Graphipterus wahlbergi Boheman (new status), and Graphipterus westwoodi Brême (new status).
Diagnostic features are provided for each species and adult specimens of each species are illustrated.
