INSECT SCIENCE, Issue 3 2000
XU Wei-an
Abstract The present paper describes two new species of Microgaster Latreille, 1804, viz: M. longiterebra sp. nov. (,) and M. longicaudatus sp. nov. (,). M. longiterebra sp. nov. is described from Kunming, Yunnan Prov. in China closely related to M. subcompletus, but differs from the latter in the combination of the following features: 1) APOL as long as OD; 2) Mesonotum strongly punctate on anterior 2/ 3) r shorter than width of stigma; 4) cu-a of hind wing medially curved; 5) Apex of hypopygium ending far beyond apex of abdomen. M. longicaudatus sp. nov. is described from Tianmushan, Zhejiang Prov. in China closely related to M. ductilis, but differs from the latter in the combination of the following features: 1) middle and hind femora reddish yellow only with apical 1/4 blackish; 2) 1-SR 0.5 times as long as 1-M; 3) the hairy part of ovipositor sheath 0.5 times as long as hind tibia; 4) tergite 3 with slightly weaker rugosity. The type specimens are deposited in Zhejiang University, Hangzhou, China. [source]


TWO NEW SPECIES OF MICROPLITIS FOERSTER (HY-MENOPTERA: BRACONIDAE) FROM CHINA,

INSECT SCIENCE, Issue 2 2000
XU Wei-an
Abstract, The present paper describes two new species of Microplitis Fcerster 1862, viz: Microplitis zhaoi Xu et He sp. nov. and Microplitis choui Xu et He sp. nov. The type specimens are deposited in Zhejiang University, Hangzhou, China. 1. Microplitis zhaoi sp. nov. is described from Fujian and Zhejiang Provinces in China closely related to Microplitis malimba Papp, but differs from the latter in the combination of the following features: 1) l-R1 shorter than stigma; 2) sternites 1,3 yellowish white; 3) submarginal cell of hind wing 2 times as long as basal width and 4) r as long as 2-SR. 2. Microplitis choui sp. nov. is described from Shaanxi and Gansu Provinces in China closely related to Microplitis zhaoi sp. nov. but differs from the latter in the combination of the following features: 1) r shorter than 2-SR; 2) sternites 1,3 blackish: 3) tergites 2,3 black; 4) cu-a of hind wing strongly sloped outward and 5) antenna shorter than body.

A New Species of the Family Juraperlidae (Insecta: Grylloblattida) from the Middle Jurassic of China

ACTA GEOLOGICA SINICA (ENGLISH EDITION), Issue 4 2010
CUI Yingying
Abstract: Juraperla grandis sp. nov. (Grylloblattida: Juraperlidae) is described from the Daohugou locality (Middle Jurassic, China). Its wing venation is very similar to that of Juraperla daohugouensis Huang and Nel, 2007 (Grylloblattida: Juraperlidae), in the particular occurrence of a supplementary longitudinal vein in the area between the anterior wing margin and ScP. The larger size of the new specimen, the lower number of CuAl branches, and the occurrence of two rows of cells between MP and CuA in forewings justify the erection of a new species, J. grandis sp. nov.. The material also preserved hind wing and body structures, described for the first time in Juraperlidae. [source]


Local host ant specificity of Phengaris (Maculinea) teleius butterfly, an obligatory social parasite of Myrmica ants

ECOLOGICAL ENTOMOLOGY, Issue 5 2010
MAGDALENA WITEK
1. Phengaris butterflies are obligatory social parasites of Myrmica ants. Early research suggested that there is a different Myrmica host species for each of the five European Phengaris social parasites, but more recent studies have shown that this was an oversimplification. 2. The pattern of host ant specificity within a Phengaris teleius metapopulation from southern Poland is reported. A combination of studying the frequency distribution of Phengaris occurrence and morphometrics on adult butterflies were used to test whether use of different host species is reflected in larval development. 3. Phengaris teleius larvae were found to survive in colonies of four Myrmica species: M. scabrinodis, M. rubra, M. ruginodis, and M. rugulosa. Myrmica scabrinodis was the most abundant species under the host plant but the percentage of infested nests was similar to other host ant species at two sites and lower in comparison to nests of M. rubra and M. ruginodis at the other two sites. Morphometric measurements of adult butterflies reared by wild colonies of M. scabrinodis and M. ruginodis showed that wing size and number of wing spots were slightly greater for adults eclosing from nests of M. ruginodis. 4. Our results suggest that P. teleius in the populations studied is less specialised than previously suggested. The results are consistent with the hypothesis that P. teleius is expected to be the least specific of the European Phengaris species, as it has the largest and best defended fourth-instar caterpillars and, as a predatory species, it spends less time in the central larval chambers of the host colonies. The fact that individuals reared by M. ruginodis had wider hind wings may suggest that P. teleius had better access to resources in M. ruginodis than in M. scabrinodis colonies. [source]


Insect wing shape evolution: independent effects of migratory and mate guarding flight on dragonfly wings

BIOLOGICAL JOURNAL OF THE LINNEAN SOCIETY, Issue 2 2009
FRANK JOHANSSON
Although, in some insect taxa, wing shape is remarkably invariant, the wings of Anisopteran dragonflies show considerable variation among genera. Because wing shape largely determines the high energetic costs of flight, it may be expected that interspecific differences are partly due to selection. In the present study, we examined the roles of long-distance migration and high-manoeuvrability mate guarding in shaping dragonfly wings, using a phylogeny-based comparative method, and geometric morphometrics to quantify wing shape. The results obtained show that migration affects the shape of both front and hind wings, and suggest that mate guarding behaviour may also have an effect, especially on the front wing. These effects on front wing shape are at least partly independent. Our findings are interesting when compared with the geographically widespread and ecologically diverse dipterans Acalyptratae (including the genus Drosophila). The wings in that group are similar in function and structure, but show strikingly low levels of interspecific variation. © 2009 The Linnean Society of London, Biological Journal of the Linnean Society, 2009, 97, 362,372.

Hybridization, developmental stability, and functionality of morphological traits in the ground beetle Carabus solieri (Coleoptera, Carabidae)

BIOLOGICAL JOURNAL OF THE LINNEAN SOCIETY, Issue 1 2006
STEPHANE GARNIER
The assessment of developmental stability in hybrids can provide valuable information in the study of species formation because it allows an evaluation of the degree of incompatibility of genetic systems that control developmental processes. The present study assessed the impact of two hybridization events, assumed to have occurred at different times, on developmental instability in the ground beetle Carabus solieri. Developmental instability was estimated in 678 individuals from 27 populations from the fluctuating asymmetry (FA) levels of four morphological traits: the tibia length of middle and hind legs, which are functional structures, and the length and the proximal width of the hind wings, which are vestigial and thus nonfunctional structures. Significant variations of FA levels between populations were shown only for the wing width. For this trait, FA levels in hybrids were higher than in their parental entities for both hybridization events, indicating a significant divergence of the gene systems controlling development between the parental entities in the two hybridization cases. As expected, wing traits exhibited FA levels at least three times higher than leg trait. Finally, the potential interest of vestigial traits in the particular context of hybridization is discussed. © 2006 The Linnean Society of London, Biological Journal of the Linnean Society, 2006, 89, 151,158.
