Additionally, each lineage is discretely diagnosable from one another based on morphology and color pattern and most occur in specific geographic regions (upland areas, karst formations or islands) that prevent or greatly restrict interpopulation gene flow. Six of these lineages were masquerading under the nomen C. intermedius and are described as the following: Cyrtodactylus auralensis sp. nov. endemic to Phnom Aural, the highest mountain in Cambodia; C. bokorensis sp. nov. endemic to the Bokor Plateau, Cambodia; C. cardamomensis sp. nov. from the main block of the Cardamom mountains; C. thylacodactylus sp. nov. endemic to Phnom Dalai the northernmost peak of the Cardamom mountains; C. laangensis sp. nov. endemic to the Phnom Laang karst formation, Cambodia; and C. septimontium sp. nov. from the Bay Nui Hills of southwest Vietnam.

    查看更多>>摘要：This paper describes the Photafish System, an innovative technique for capturing high-quality digital images of live freshwater fishes and other aquatic organisms in the field. This system may improve and facilitate the visual documentation of such organisms to illustrate guidebooks, populate online databases and support scientific papers, particularly taxonomic ones. The system was designed and tested to produce Taxonomically Informative Photos (TIPs) of living specimens and employs an Aquarium Assembly for Photography (AAP) distinguished by its portability and low cost. Using Neotropical freshwater fishes as a model, we propose an optimized protocol for documenting the morphology of live specimens to support taxonomy, as well as awareness and conservation of freshwater biodiversity. This paper addresses the technical aspects and challenges of field studio photography in remote locations. Tricks gleaned from personal experiences with nature photography are also shared. Finally, we briefly discuss the advantages and weaknesses of our approach.

    A new species of Moina Baird, 1850 (Cladocera: Moinidae) from Thailand

    20页
    查看更多>>摘要：A new species of Moina Baird, 1850 (Cladocera: Moinidae) is described based on material collected from Thailand (South-East Asia). In tropical Asia, Moina siamensis sp. nov. could be confused easily with M. weismanni Ishikawa, 1896, because of morphological similarities in parthenogenetic females and males of both species. The outstanding difference between these two taxa concerns the structure of the ephippium in gamogenetic females, which is highly visible under light and scanning electron microscopes. The mature ephippium of M. weismanni is strongly tuberous, with distinct borders between cells, whereas the ephippium of M. siamensis sp. nov. is significantly less tuberous, with prominent longitudinal lines in its central region. Since gamogenetic females only appear sporadically in moinid populations, distribution ranges of M. siamensis sp. nov., M. weismanni and sibling taxa must be clarified precisely using genetic markers in the future. Preliminary investigations of the ephippium structure may be useful for estimating the differences between populations, thus revealing much diversity within Moinidae.

    Systematic significance of antennal segmentation and sense cones in Thripidae (Thysanoptera: Terebrantia)

    Zhang, ShimengMound, Laurence A.Feng, Jinian
    16页
    查看更多>>摘要：Variation is discussed concerning the number of antennal segments in adults, and the number of their sense cones, among 182 of the 289 genera of Thripidae. Brief comments are also made concerning antennal structure and sensoria among the other seven terebrantian families. The plesiotypic condition for Thysanoptera is 9-segmented antennae, but fusion between various segments leads to a reduction in number to as few as five segments, and such fusion occurs in unrelated species. In Thripidae, antenna! segment III never bears more than one sense cone, but the distribution of sense cones on segments IV-VIII varies and is tabulated. On antenna! segment IV, species in nearly all Panchaetothripinae genera and more than half of Thripinae genera have two sense cones, but genera of Dendrothripinae and Sericothripinae bear only one on this segment. The differing patterns of segmental fusion that occur in Thripidae are discussed in association with the number of sense cones on VI-VIII; species with 7, 8 or 9 segmented antennae almost always lack a sense cone on the terminal segment. It is concluded that the number of antennal segments is subject to irregular homoplasy, and is thus sometimes an unreliable indicator of relationships.

    Overview of the lady beetle tribe Diomini (Coleoptera: Coccinellidae) and description of a new phytophagous, silk-spinning genus from Costa Rica that induces food bodies on leaves of Piper (Piperaceae)

    Vandenberg, Natalia J.Hanson, Paul E.
    31页
    查看更多>>摘要：A new genus of lady beetle, Moiradiomus gen. nov. (Coleoptera: Coccinellidae Latreille, 1807: Diomini Gordon, 1999), and four new species are described from Costa Rica, representing the first known occurrences of obligate phytophagous lady beetle species outside of the tribe Epilachnini Mulsant, 1846 (sens. Slipinski 2007). The new species are described, illustrated and keyed, and their life histories discussed. Each species of Moiradiomus occurs on a separate species of Piper L., 1753 (Piperaceae Giseke, 1792), where the larva constructs a small silken tent between leaf veins and inside this shelter induces the production of food bodies, which are its exclusive source of food. Background information is provided on lady beetle trophic relations and other insect/Piper symbioses. The taxonomic history of Diomus Mulsant, 1850 and related species in the tribe Diomini is reviewed and existing errors in observation, interpretation, identification, and classification are corrected in order to provide a more meaningful context for understanding the new genus. The tribe Diomini is rediagnosed and recircumscribed to include Diomus, Decadiomus Chapin, 1933, Heterodiomus Brethes, 1925, Dichaina Weise, 1923, Andrzej Slipinski, 2007, and Moiradiomus. Magnodiomus Gordon, 1999 and Erratodiomus Gordon, 1999 are removed from Diomini and transferred to Hyperaspidini Costa, 1849, subtribe Selvadiina Gordon, 1985 stat. nov. Mimoscymnus Gordon, 1994 and Planorbata Gordon, 1994, originally described in Coccidulini Mulsant, 1846 are also transfered to Hyperaspidini and placed in Mimoscymnina subtribe nov. (type genus Mimoscymnus). The main morphological characters distinguishing Diomini and Hyperaspidini are described and illustrated. A key to genera of Diomini sensu novo is provided. The identification of the Australian Diomus species illustrated in Gordon's publication on North American lady beetles is corrected from D. pumilio Weise, 1885 to D. tenebricosus (Boheman, 1859), however specimens recently collected in California do not match these genitalic illustrations and are identified as true D. pumilio. The following species of Diomus are transferred to Decadiomus as new combinations: D. balteatus (LeConte, 1878), D. floridanus (Mulsant, 1850), D. amabilis (LeConte, 1852), D. liebecki (Horn, 1895), D. myrmidon (Mulsant, 1850), D. humilis (Gordon, 1976), D. pseudotaedatus (Gordon, 1976), D. taedatus (Fall, 1901), D. bigemmeus (Horn, 1895), and D. austrinus (Gordon, 1976). Decadiomus seini Segarra, 2014 is placed as a junior synonym of D. austrinus. The following new species of Moiradiomus are described: M. clotho sp. nov., M. lachesis sp. nov., M. atopos sp. nov., M. nanita sp. nov.

    A New Species of the Graphium (Pazala) mandarinus Group from Central Vietnam (Lepidoptera: Papilionidae)

    Hu, Shao-JiCondamine, Fabien L.Monastyrskii, Alexander L.Cotton, Adam M....
    15页
    查看更多>>摘要：The Graphium (Pazala) mandarinus group was recently defined and the status of taxa as well as the number of species was revised. We report here the discovery of a new species from Kon Tum plateau of the Truong Son (Annamite) Range of Central Vietnam, which we describe based on morphological and molecular evidence. Molecular phylogeny shows that the new taxon, G. (P.) wenlingae Hu, Cotton & Monastyrskii sp. nov., is sister to G. (P.) daiyuanae Hu, Zhang & Cotton, 2018 plus G. (P.) confucius Hu, Duan & Cotton, 2018. Molecular dating analysis further suggests that this new species diverged from its sister Glade in the Pliocene (similar to 3.5 million years ago). The new taxon constitutes the eighth and southern-most species of the mandarinus group.
