Abstract: A new species of the extinct bee genus Ctenoplectrella Cockerell (Megachilinae: Ctenoplectrellini) is described and figured from two females preserved in a single piece of middle Eocene (Lutetian) Baltic amber. Ctenoplectrella gorskii Engel, sp. n. is distinguished from other species of the genus most notably in the venation of the forewing.

Abstract: The Oriental, Australasian and Oceanian species of the genus Amygdalops Lamb, 1814 (Diptera, Anthomyzidae) are revised. The genus is re-diagnosed on the basis of the morphological diversity revealed. Fifteen species are recognized, keyed and illustrated. Descriptions of 8 species new to science are given, viz., A. abnormis sp. n. (Sri Lanka, India), A. bisinus sp. n. (Thailand, Vietnam, Indonesia: Flores I.), A. curtisi sp. n. (Thailand, Taiwan), A. curtistylus sp. n. (Thailand), A. cuspidatus sp. n. (Indonesia: Flores I., Taiwan), A. pappi sp. n. (Thailand), A. silaceus sp. n. (Mariana Is.), A. stenopteryx sp. n. (Thailand). Three species, A. geniculatus de Meijere, 1916 (only known from Indonesia: Java), A. lineola de Meijere, 1916 (new records from Thailand, Indonesia: Java, Flores I. and Papua New Guinea) and A. nigrinotum Sueyoshi et Roháček, 2003 (widespread, many new records) are redescribed including revision of available type specimens and remaining 4 species are diagnosed but left unnamed owing to insufficient material. Lectotype of A. geniculatus is designated. The relationships of all species are discussed on the basis of newly discovered features of the male and female postabdominal structures and their known distribution is reviewed. Notes on the phylogeny and biogeography of Amygdalops species are provided along with 164 original figures.

Abstract: We investigated environmental factors grouped along hierarchical spatial scales influencing the egg density of a monophagous papilionid, the southern festoon (Zerynthia polyxena) on its food-plant, the birthwort (Aristolochia clematitis). Two patch level variables were considered: habitat type (black locust plantation, clearing and hummock) and food-plant patch size. We measured several plant variables at the egg-bearing shoots. We counted the number and measured the mean height of birthworts within the microenvironment of the egg-bearing shoots. We also measured the height and counted the leaves of each egg-bearing shoot itself. Plant apparency was defined as the height difference between egg-bearing shoots and the surrounding ones. Two variables were measured on the egg-bearing shoots (hence at food-plant scale): number of leaves and position of eggs on the leaf-storeys. Habitat type affected the distribution of eggs; black locust plantations and hummocks were preferred against clearings. At a smaller scale, neither shoot density, nor food-plant apparency affected egg distribution. At the plant level, the number of eggs increased with the number of leaves, and the position of eggs also co-varied with egg density, having fewer eggs in clusters positioned higher on shoots. We conclude that spatially correlated data on butterfly egg distribution should be analysed considering the intrinsically hierarchical structure of environmental factors.

Abstract: Interspecific and intraspecific variation in the body sizes of warm-blooded animals is usually correlated with geographical gradients (latitude and/or altitude) according to the well-known Bergmann's rule. However, what determines conformity to Bergmann"s rule or even whether this rule is valid has been debated. We tested the relationships between skull size of the plateau pika (Ochotona curzoniae) collected from different geographic localities and two geographic variables (latitude and altitude) as well as some environmental factors that usually change with geographical gradients on the Qinghai-Tibetan Plateau. Our results indicated that skull size was positively correlated with both latitude and altitude, and negatively correlated with annual temperature, annual precipitation, and annual net primary production. These results indicated conformity to Bergmann"s rule in this species, i.e., the body size of the plateau pika tends to increase with climate severity and food scarcity.
