查看更多>>摘要:This paper serves as an introduction to a world monographic series addressing the species-level taxonomy of the ant genus Nylanderia. This series will consist of several regionally based taxonomic revisions. The systematics and biology of Nylanderia are discussed in a global context, and a diagnosis of the genus is given. Several morphological features, which are considered putative synapomorphies for the genus, are provided. Morphological descriptions of all three castes (workers, queens, and males)are provided and discussed.
查看更多>>摘要:The taxonomy of the Afrotropical Nylanderia fauna is revised for the first time. Fourteen native species are revealed, of which eight are described as new: N. boltoni LaPolla and Fisher, N. brevisetula LaPolla and Fisher, N. impolita LaPolla and Fisher, N. luteafra LaPolla and Fisher, N. scintilla LaPolla and Fisher, N. silvula LaPolla and Fisher, N. umbella LaPolla and Fisher, and N. usambarica LaPolla, Hawkes and Fisher. Two species, N. jaegerskioeldi and N. natalensis, have workers that are indistinguishable from each other, and males are the only reliable way to separate these two species. Three non-native Nylanderia species are thought to have been introduced to Africa: N. bourbonica, N. vaga, and N. vividula. An identification key to the worker caste is provided.

Here the external morphology of immatures of Galeacius martini Schouteden is described. Adults and nymphs were maintained in laboratory and fed on branches of Miconia sellowiana with fruits. The egg of G. martini is semi-spherical, reddish brown, with reticulations Surrounding smaller granulated sculpturing under scanning electron microscopy (S.E.M). The nymphs from first to fifth instar have a stridulitrum plus plectrum, and 2+2 trichobothria posterior to spiracles on abdominal sternites III—VII. The dorso-abdominal scent efferent system has an evaporatorium with two distinct mycoid sculpturing,and their are two types of peritreme on medial plates II and III in first and fifth instar. The color and chorion morphology may distinguish G. martini from other scutellerid eggs so far described. New descriptions of immatures of Scutelleridae are particularly desirable, mainly with emphasis some structures on S.E.M., as stridulatory devices, dorso-abdominal scent efferent system, and trichobothria, thus improving the knowledge about the taxon.

Many Syngrapha inhabit the subarctic zone or high elevation mountains. Thegenus is close to Autographa but differs from it in a variety of male and female genitalic characteristics (see revision of Eurasian fauna by Ronkay & al. 2008). In the course of faunistic studies on Noctuidae of the Altai Mountain Country, an undescribed species of Syngrapha was identified among specimens at the Zoological Museum of the Institute of Systematics & Ecology of Animals Siberian Branch of RAS (SZMN; Novosibirsk, Russia) and at the Zoological Institute of the Russian Academy of Sciences (ZISP; Saint-Petersburg, Russia). It is described herein as new. We use the term Altai Mountain Country (Fig. 1) in the geo-botanical sense of Kamelin (1998, 2005) to include: the Russian, Kazakhstanian, Chinese and Mongolian Altai; the mountains of BoundaryDzhungaria (Tarbagatai and branches, Manrak, Semistai and Saur); the Zaisan intermountain depression; the mountains of SW Tyva and the main part of the Western Sayan ridges adjacent to the meridional Shapshal Ridge, north to the Abakan Ridge; east to theYenisey river; and south to the Baitak-Bogdo Ridge and nearby highlands together with the mountains enclosing the depression of the "Dzhungarian Gobi" and the Adzh-Bogd-uul Ridge. The Altai Mountain Country does not include the Kuznetzky Alatau, the steppe depressions of Khakassia and Western Tyva, the Mongolian Big Lakes depression and the Khan-BChuhay Ridge, or the Gobian Altai massif (Kamelin 2005).
查看更多>>摘要:Recent molecular studies have shown that the genus Toxoptera is polyphyletic, and in particular that the name of the aphid known since 1952 as Toxoptera odinae (van der Goot) should revert to Aphis odinae (van der Goot), stat. rev. In this paper oviparae, alate males and fundatrices of A. odinae are described for the first time, from Japan. A. odinae is common as a grey-brown or rust-brown aphid on numerous plant species of shrubby habit throughout the Old World tropics and sub-tropics, but in temperate east Asia much darker forms occur, and Japanese populations of A. odinae include a dark green form not found elsewhere in the world. Multivariate morphometries were used to confirm that both colour forms of the aphid in Japan were conspecific with samples from other parts of the world. Pergandeida kalopanacis Hori 1927 is a new synonym of A. odinae.

The main morphological characteristics that can be used to distinguish them from other species of genus are presented. Baetodes awa sp. nov.: labrum with subapical row of six setae of subequal length, glossa with two pectinate bladelike setae of the same length, abdominal tubercles present but very small; Baetodes diasae sp. nov.: labrum with subapical row of 3+13 setae of subequal length, glossa with two pectinate bladelike setae, one gill on each coxa with a small basal projection. Baetodespseudospinae sp. nov.: glossa with one pectinate bladelike seta, two tubercles on pronotum and mesonotum, prominent tubercle on metanotum, larger than that of first abdominal segment. Besides the descriptions of the new species a key for the identification of the Colombian species of Baetodes is presented for the first time
