An experiment was carried out with Mansonia mosquitos in an area endemic for subperiodic Brugia malayi to assess the applicability of the mark-release-recapture method to these mosquitos. An estimated 17,880 individuals of six species of Mansonia were marked with fluorescent dust and released: 453 Ma. annulata, 305 Ma. annulifera, 6,200 Ma. bonneae, 516 Ma. dives, 3,998 Ma. indiana and 6,408 Ma. uniformis. Twenty-three marked individuals were recaptured. Most recaptures were made one or two nights after their release, but one Ma. annulifera was recaptured five nights later and one Ma. bonneae had been marked and released 6-11 nights previously. The recaptured mosquitos were collected between 0.5 and 2.4 km from their release points.
In the crystal structure of the title compound, C(12)H(10)N(4), the pyridine ring makes a dihedral angle of 1.12 (9) degrees with the mean plane of the complete almost planar and crystallographically centrosymmetric molecule. There are stacks of parallel molecules along the a-axis direction, with alternate stacks having a herring-bone arrangement relative to each other and an interplanar spacing of 3.551 A.
Motschulsky (1859), a Russian Imperial Army Colonel and entomologist, established the genus Exopholis, described E. birmannica and transferred Melolontha hypoleuca Wiedemann, 1819 to it. Brenske (1896) described Exopholis philippinica from the "Philippinen" from a single female specimen. Dalla Torre (1912), listed eight species under the genus Exopholis Motschulsky, 1859 from South East Asia: E. hypoleuca (Weidemann, 1819) (Myanmar, Malaysia, Borneo, Java, Sumatra, Nias, Ambon), E. costata (Burmeister, 1855) (Java, Nias), E. birmanica Motschulsky, 1859 (Myanmar), E. lacordairei Waterhouse, 1867 (Borneo), E. pinguis Lansberge, 1879 (Sumatra), E. brenskei Nonfried, 1891, E. borneensis Brenske, 1894 (both from Borneo) and E. philippinica Brenske, 1896 (Philippines). This paper aims to review the taxonomy of Exopholis from the Philippines. Specifically, to focus on the diagnosis of Exopholis philippinica and its geographic distribution.
The Miltochrista obliquilinea (Swinhoe, 1901) species-group is revised. Four new species are described: M. konta Volynkin, Černý N. Singh, sp. n. (Thailand, Laos and Vietnam), M. adelfika Volynkin, N. Singh, Černý, Kirti Datta, sp. n. (India, Myanmar, China, Thailand, Laos and Vietnam), M. stenovalva Volynkin, N. Singh, Černý, Kirti Datta, sp. n. (India and Thailand) and M. lavides Volynkin, Černý N. Singh, sp. n. (Malaysia, Thailand, Myanmar, Laos and Vietnam). The lectotype for Lyclene obliquilinea Swinhoe, 1901 is designated. Adults, male and female genitalia are illustrated.
Nipponophloeostiba thayeri Shavrin, sp.n. from Borneo Island, Sabah (Malaysia) is described, illustrated and compared with Japanese N. verrucifera Watanabe, 1962.
The first representative of the genus Cerapus in Malaysian waters, Cerapus bumbumiensis sp. nov. is described from specimens sampled from Pulau Bum Bum, Sabah (east Malaysia). The main identifying characteristics of this new amphipod species are: pereonites 1, 2 with constriction; male gnathopod 2 carpochelate, carpus large with long defining posterior tooth and well-developed anterodistal tooth; pereopod 6 coxa with fine hair/fringe setae ventrally; and telson with deep cleft. An updated identification key for the 23 known species in the genus is also presented.
A new silvanid genus Borneophanusgen. n. is described based on specimens collected from Malaysian Borneo. A new species, B.spinosussp. n., is described herein. Digitiform sensilla on the apical maxillary palpomere is reported in Silvanidae for the first time.
The phasmid genus Ramulus Saussure, 1862 belongs to the nominotypical tribe of subfamily Clitumninae of the Phasmatidae. This genus consists of 159 species distributed in India (21 species), Sri Lanka (6 species), Bhutan (1 species), Myanmar (6 species), Thailand (1 species), Vietnam (12 species), Malaysia (4 species from Peninsular part and Borneo), Indonesia (18 species from Java, Sumatra, Borneo, Sulawesi, and Key islands), the Philippines (3 species), China including Taiwan (74 species), Japan (1 species), Korea (1 species), and Russia (1 species) (Brock et al., 2021). Three phasmid species have been described in the genus Baculum Saussure, 1861 from the Russian Far East, Korea and North-East China respectively (Bey-Bienko, 1960; Kwon et al., 1992; Chen He, 1994) and later transferred to the genus Ramulus (Otte Brock, 2005). As a result of detailed examination of the type specimens of Ramulus ussurianus (Bey-Bienko, 1960), additional material and descriptions of these species, it became clear that specimens from Russia, Korea and North-East China are conspecific.
A new peculiar, spiky, and yellowish species of the genus Tegotettix Hancock, 1913 is described from the Davao region of the island of Mindanao (the Philippines)-T. derijei sp. n. (Mindanao horned pygmy devil). The species is visually similar to T. cristiferus (Günther, 1935) from Borneo and T. armatus Hancock, 1913 from Borneo, which is the type species of the genus, and of which a new record from Sabah is also presented in the study. The new species is also similar to an undescribed species from Bukidnon, which we presented by photographs in its natural habitat. To date, T. armatus was known only from old descriptions and drawings and has not been reported for more than 100 years. A brief overview of the species of the genus Tegotettix, with its division into three species groups, is presented.
Based on material collected by canopy fogging in forests on Borneo, Obhylius arboricola gen. nov., sp. nov., and Seticotasteromimus brunomanseri sp. nov., the second species of this genus, are described. Further records of the type species of Seticotasteromimus Germann, 2013, S. jarawa Germann, 2013, are presented from Borneo, some 2700 km distant from the type locality on the Andaman Islands. Along with Seticotasteromimus, the new genus is best placed in the subtribe Cotasteromimina.
The Tropical Council for Companion Animal Parasites Ltd. (TroCCAP) is a not-for-profit organisation whose mission is to independently inform, guide and make best-practice recommendations for the diagnosis, treatment and control of companion animal parasites in the tropics and sub-tropics, with the aim of protecting animal and human health. In line with this primary mission, TroCCAP recently developed guidelines for the diagnosis, treatment and control of feline and canine parasites in the tropics. The development of these guidelines required unique and complex considerations to be addressed, often inapplicable to developed nations. Much of the tropics encompass middle-to-low income countries in which poor standards of environmental hygiene and large populations of stray dogs and cats coexist. In these regions, a range of parasites pose a high risk to companion animals, which ultimately may place their owners at risk of acquiring parasitic zoonoses. These considerations led to the development of unique recommendations with regard, for example, to deworming and endoparasite testing intervals for the control of both global and 'region-specific' parasites in the tropics. Moreover, the 'off-' or 'extra'-label use of drugs for the treatment and control of parasitic infections is common practice in many tropical countries and many generic products lack manufacturers' information on efficacy, safety, and quality control. Recommendations and advice concerning the use of such drugs and protocols are also addressed in these guidelines. The formation of these guidelines is an important first step towards improving the education of veterinarians specifically regarding best-practice for the diagnosis, treatment and control of canine and feline parasites in the tropics.
For the first time in 21 years, a new genus of cardiochiline braconid wasp, Orientocardiochiles Kang & Long, gen. nov. (type species Orientocardiochiles joeburrowi Kang, sp. nov.), is discovered and described. This genus represents the ninth genus in the Oriental region. Two new species (O. joeburrowi Kang, sp. nov. and O. nigrofasciatus Long, sp. nov.) are described and illustrated, and a key to species of the genus, with detailed images, is added. Diagnostic characters of the new genus are analyzed and compared with several other cardiochiline genera to allow the genus to key out properly using an existing generic treatment. The scientific names validated by this paper and morphological data obtained from this project will be utilized and tested in the upcoming genus-level revision of the subfamily based on combined morphological and molecular data.
