Numerical Taxonomic Study

This study examines whether a satisfactory classification of Turkish Lathyrus species can be obtained from phenetic clustering based on external vegetative and floral morphological characters of herbarium specimens. Forty morphological characters for each species of the genus Lathyrus L. were scored and the data subjected to numerical taxonomic analyses. The results of this study suggest that there are basically nine sections (Orobus, Lathyrostylis, Aphaca, Nissolia, Orobon, Gorgonia, Clymenum, Cicercula and Lathyrus) which can be grouped under two subgenera, namely subgenus Lathyrus and subgenus Orobus, as far as the material belonging to 54 of the 58 species cited in Flora of Turkey allows. Sect. Gorgonia Dogan is described.

Typhlodromus Caudiglans

Variation in morphological characters between Canadian populations of Typhlodromus caudiglans Schuster (Acarina: Phytoseiidae) was examined by the methods of numerical taxonomy. Western populations are separated from the other populations when multivariate tests are used. Two subspecies are proposed, and Typhlodromella nodosus De Leon is synonymized with Typhlodromus caudiglans. Morphological variations between northern and eastern populations are correlated with climatic variables and with host plants.

Numerical Taxonomic Study

A systematic study of 29 taxa belonging to 7 genera of subfamilies Balanitoideae, Zygophylloideae, Peganoideae, Tribuloideae, Seetzenioideae and Tetradiclidoideae of Zygophyllaceae from Egypt was carried out by means of numerical analysis based on sixty-one morphological characters, including vegetative parts, pollen grains and seeds. On the basis of UPGMA clustering and PCO analysis, six main groups are recognized. Representatives of these groups are clustered together based on characters with high factor loadings in the PCO analysis. The results indicate that Zygophyllaceae are heterogeneous, including Peganum harmala which has been proposed to belong in a separate family. Zygophylloideae, Tribuloideae, Tetradiclidoideae and Seetzenioideae are the most homogeneous groups. Sections and groups in both Tribulus and Fagonia seem artificial.

Abstract A northward trans-Wallacean radiation is demonstrated for Chrysorthenches, a member of the Orthenches group. Here we review Chrysorthenches and allied genera resulting in a generic transfer of Diathryptica callibrya to Chrysorthenches and two new congeners: C. muraseaeSohn & Kobayashisp. nov. from Japan and C. smaragdinaSohnsp. nov. from Thailand. We review morphological characters of Chrysorthenches and allied genera, and find polyphyly of Diathryptica and the association of the Orthenches-group with Glyphipterigidae. These findings were supported in a maximum likelihood phylogeny of DNA barcodes from ten yponomeutoids. We analysed 30 morphological characters for 12 species of Chrysorthenches, plus one outgroup, via a cladistic approach. The resulting cladogram redefined two pre-existing Chrysorthenches species-groups and identified one novel lineage: the C. callibrya species-group. We review the host associations between Chrysorthenches and Podocarpaceae, based on mapping the working phylogenies. Our review suggests that ancestral Chrysorthenches colonized Podocarpus and later shifted to other podocarp genera. Biogeographical patterns of Chrysorthenches show that they evolved long after the Podocarpaceae radiation. Disjunctive trans-Wallacean distribution of the C. callibrya species-group is possibly related to the tracking of their host-plants and the complicated geological history of the island-arc system connecting Australia and East Asia.

Wax Moth

The greater wax moth, Galleria mellonella Linnaeus, is well known as a pest of honey bees and for the biodegradation of wax and polyethylene by their larvae. The genus Galleria has long been considered monotypic and found worldwide. A taxonomic study of the genus Galleria is presented based on morphological and molecular characters (COI, CAD, wg). A new species (Galleria similis Roh & Song, sp. nov.) is recognized on the Korean peninsula. The new species is superficially similar to G. mellonella but they can be separated by the structures of hindwing venation and male genitalia. Habitus photographs and illustrations of diagnostic characters are provided.

Megaxyela Ashmead, 1898 comprises 13 species, four of which are described as new and one is removed from synonymy: Megaxyela euchroma Blank, Shinohara & Wei sp. nov. from China (Zheijang), M. fulvago Blank, Shinohara & Wei sp. nov. from China (Hunan, Jiangsu, Zhejiang), M. inversa Blank & D.R. Smith sp. nov. from the USA (West Virginia), M. langstoni Ross, 1936 sp. rev. from the eastern USA, and M. pulchra Blank, Shinohara & Sundukov sp. nov. from China (Hubei, Jilin, Liaoning, Shaanxi, Tibet), South Korea (Kangwon-do) and Russia (Primorskiy Kray). The male of M. parki Shinohara, 1992 is described for the first time. A lectotype is designated for M. gigantea Mocsáry, 1909. A cladogram, based on COI sequences of seven species, is presented and interpreted in view of selected morphological characters. Records of M. fulvago sp. nov. from Hunan and of M. pulchra sp. nov. from Tibet extend the known distribution of Megaxyela in the Old World 600 kilometers farther south and 2500 kilometers farther west than previous records.

ABSTRACT A taxonomic study of the genus Artabotrys R. Br. (Annonaceae) in Java and the Lesser Sunda Islands was conducted based on morphological characters. The objective of this study is to determine the diversity, describe and make determination key of Artabotrys which found in Java and the Lesser Sunda Islands. The method used in this study is descriptive. This study was conducted on May-June 2015 in the collection room wing B 2nd floor, type room, and Laboratory of Biosystematic Herbarium Bogoriense - Bidang Botani Puslit Biologi LIPI, Cibinong, Bogor, West Java. The result showed that there are three species of Artabotrys in Java and Lesser Sunda Islands. Artabotrys species found in Java, namely A. hexapetalus, A. suaveolens and A. sumatranus, while the species of the Lesser Sunda Islands only A. hexapetalus. Phenetic analysis shows that the species of Artabotrys in Java and the Lesser Sunda Islands are divided into two subgroups. Determination key and descriptions also provided to identify the species of Artabotrys in Java and Lesser Sunda Islands. Artabotrys natural habitat is lowland forest but now lowland forests decreased. This can lead to biodiversity (including Artabotrys) to be reduced, so that conservation need to be done (conservation both on Artabotrys and lowland forest).   Keywords : Artabotrys, Annonaceae, diversity, determination key, Lesser Sunda Islands
