We found distinct pelage characters in Finlayson’s squirrel (Callosciurus finlaysonii) population, which is endemic to Lao Island of the Cham Islands, located off the coast of central Vietnam. Among squirrels of the ‘C. erythraeus-finlaysonii complex’, which consists of all forms of C. erythraeus and C. finlaysonii, mitochondrial cytochrome-b sequences show that the Lao Island squirrel forms a cluster with C. finlaysonii with external characters of C. erythraeus flavimanus, defined previously as ‘C. finlaysonii morpha flavimanus’. Both squirrel forms, however, differed in pelage colour. This different colouration may have arisen from the effect of geographic isolation.

Two new species of oribatid mites of the genus Xenillus (Oribatida, Liacaridae) are described from leaf litter in a rain forest in Bolivia. Xenillus pseudobolivianus sp. n. is similar to X. bolivianus and X. neonominatus in the morphology of lamellar cusp, length of bothridial and interlamellar setae and length and morphology of dorsal notogastral setae, but differs from both by the morphology of bothridial head and interlamellar and notogastral setae, the ornamentation of the notogaster, and the different length of some notogastral setae. Xenillus amboroensis sp. n. is similar to X. amazonensis, X. disjunctus, X. diversisetosus, X. fecundus, X. longipes, and X. ornatus in the morphology of bothridial seta, but differs from all by the morphology of lamellar cusp, the placement of the lamellar seta, and the different length of some notogastral setae.

An apterous viviparous female of a new aphid species Uroleucon (Uroleucon) bulgaricum sp. n. is described and compared with the similar species U. (Uroleucon) achilleae (Koch, 1865). The new species was collected by the late J. Holman in the Blagoevgrad region (SE Bulgaria), where it is associated with Achillea coarctata Poiret in Lam. (Asteraceae). The similarities and differences between other Achillea-feeding Uroleucon species are discussed. A morphological key to the species of the subgenus Uroleucon Mordvilko, 1914 in Bulgaria is presented. A modified key to the Achillea-feeding Uroleucon aphids of Blackman and Eastop is also provided.

Aporrectodea caliginosa is a universally distributed and highly abundant peregrine earthworm that is the object of many ecological and ecotoxicological studies. Molecular phylogenetic analysis suggested that A. caliginosa consists of three highly diverged genetic lineages. In this study, we investigated morphological diversity within a sample of these three lineages from Belarus. We detected a variety of forms with different degrees of pigmentation and a shift in the clitellum position. The three genetic lineages of A. caliginosa demonstrated different propensity to particular morphological variants, including size, colour, and the clitellum position, yet no character could be used to distinguish among the lineages with sufficient accuracy. Thus, our results suggest that identification of the genetic lineage should be recommended for ecological studies involving A. caliginosa to account for possible differences between them.
Aporrectodea caliginosa是一种分布广泛、数量丰富的游隼蚯蚓,是许多生态学和生态毒理学研究的对象。分子系统发育分析表明,杯状A.caliginosa由三个高度分化的遗传谱系组成。在这项研究中,我们调查了白俄罗斯这三个谱系样本的形态多样性。我们发现了各种不同程度的色素沉着和阴蒂位置的变化。caliginosa的三个遗传谱系对特定的形态变异表现出不同的倾向,包括大小、颜色和斜坡位置,但没有任何特征可以用来足够准确地区分谱系。因此,我们的研究结果表明,应建议对遗传谱系进行鉴定,以进行涉及A.caliginosa的生态学研究,以解释它们之间可能存在的差异。

Two new species of the family Galumnidae are described from soil-litter in the riverine forest of Gorongosa National Park (Central Mozambique). Allogalumna mozambiquensis Ermilov sp. n. differs from all species of the genus by the morphology of bothridial seta (with the head having a long setiform tip). Neoctenogalumna gorongosaensis Ermilov sp. n. is similar to N. congoensis in the bothridial seta with developed head, specific notogastral ornamentation and narrowly elongate postanal porose area, but differs from the latter by the smaller body size, heavily ciliate bothridial seta and diagonal position of adanal lyrifissure.

Why are there not more herbivorous insect species? 为什么没有更多的食草昆虫种类?

Insect species richness is estimated to exceed three million species, of which roughly half is herbivorous. Despite the vast number of species and varied life histories, the proportion of herbivorous species among plant-consuming organisms is lower than it could be due to constraints that impose limits to their diversification. These include ecological factors, such as vague interspecific competition; anatomical and physiological limits, such as neural limits and inability of handling a wide range of plant allelochemicals; phylogenetic constraints, like niche conservatism; and most importantly, a low level of concerted genetic variation necessary to a phyletic conversion. It is suggested that diversification ultimately depends on what we call the intrinsic trend of diversification of the insect genome. In support of the above, we survey the major types of host-specificity, the mechanisms and constraints of host specialization, possible pathways of speciation, and hypotheses concerning insect diversification.
昆虫物种丰富度估计超过300万种,其中大约一半是草食性的。尽管有大量的物种和不同的生活史,草食性物种在植物消耗生物中的比例低于其可能由于限制其多样化的限制。这些因素包括生态因素,如模糊的种间竞争;解剖和生理限制,如神经限制和不能处理广泛的植物化感物质;系统发育约束,如生态位保守性;最重要的是,低水平的协同遗传变异是种系转换所必需的。这表明,多样化最终取决于我们所说的昆虫基因组多样化的内在趋势。为了支持上述观点,我们调查了寄主特异性的主要类型、寄主专门化的机制和限制、物种形成的可能途径以及有关昆虫多样化的假设。

Mitochondrial DNA diversity of the alpine newt (Ichthyosaura alpestris) in the Carpathian Basin: evidence for multiple cryptic lineages associated with Pleistocene refugia 喀尔巴阡盆地高山蝾螈(alpestris)线粒体DNA多样性:与更新世避难所相关的多个隐蔽谱系的证据

The phylogeography and molecular taxonomy of the Alpine newt, Ichthyosaura alpestris, has been intensively studied in the past. However, previous studies did not include a comprehensive sampling from the Carpathian Basin, possibly a key region in the evolution of the species. We used a 1251 bp long fragment of the mitochondrial genome to infer the species’ evolutionary history in central-eastern Europe by assigning isolated Carpathian Basin populations from 6 regions to previously defined mtDNA lineages. We also revised the morphology-based intraspecific taxonomy of the species in the light of new genetic data. Alpine newt populations from the Carpathian Basin represented two different mitochondrial lineages. The Mátra, Bükk and Zemplén Mts populations can be assigned to the Western lineage of the nominotypical subspecies. Bakony and Őrség populations showed high haplotype diversity and formed a separate clade within the Western lineage, suggesting that the Carpathian Basin might have provided cryptic refugia for Alpine newt populations in their cold-continental forest-steppe landscapes during the younger Pleistocene. Newts from Apuseni Mts were related to the Eastern lineage but formed a distinct clade within this lineage. Considering the morphological and genetic differentiation of the Bakony and Őrség populations, consistent with a long independent evolutionary history, we propose these populations be referred to as Ichthyosaura alpestris bakonyiensis (Dely, 1964). We provide a redescription of this poorly known subspecies.
阿尔卑斯蝾螈——阿尔卑斯鱼龙的系统地理学和分子分类学在过去得到了深入的研究。然而,之前的研究没有包括从喀尔巴阡盆地进行的全面采样,该盆地可能是该物种进化的关键区域。我们使用1251bp长的线粒体基因组片段,通过将来自6个地区的喀尔巴阡盆地孤立种群分配到先前定义的mtDNA谱系,推断该物种在中东欧的进化史。我们还根据新的遗传数据修订了该物种基于形态学的种内分类学。来自喀尔巴阡山盆地的高山蝾螈种群代表了两个不同的线粒体谱系。Mátra、Bükk和Zemplén Mts种群可以归属于命名不典型亚种的西方谱系。Bakony和Őrég种群表现出高度的单倍型多样性,并在西方谱系中形成了一个单独的分支,这表明喀尔巴阡盆地可能在更新世早期为阿尔卑斯蝾螈种群在其寒冷的大陆森林草原景观中提供了隐蔽的避难所。阿普塞尼山脉的蝾螈与东部谱系有亲缘关系,但在该谱系中形成了一个独特的分支。考虑到Bakony和Őrég种群的形态和遗传分化,与长期独立的进化史一致,我们建议将这些种群称为alpestris bakonyiensis鱼龙(Dely,1964)。我们对这个鲜为人知的亚种进行了重新描述。

However, previous studies did not include a comprehensive sampling from the Carpathian Basin, possibly a key region in the evolution of the species. We used a 1251 bp long fragment of the mitochondrial genome to infer the species’ evolutionary history in central-eastern Europe by assigning isolated Carpathian Basin populations from 6 regions to previously defined mtDNA lineages. We also revised the morphology-based intraspecific taxonomy of the species in the light of new genetic data.
