Abstract
We revise the genus Conostigmus Dahlbom 1858 occurring in Madagascar, based on data from more specimens than were examined for the latest world revision of the genus. Our results yield new information about intraspecific variability and the nature of the atypical latitudinal diversity gradient (LDG) observed in Ceraphronoidea. We also investigate cellular processes that underlie body size polyphenism, by utilizing the correspondence between epidermal cells and scutes, polygonal units of leather-like microsculpture. Our results reveal that body size polyphenism in Megaspilidae is most likely related to cell number and not cell size variation, and that cell size differs between epithelial fields of the head and that of the mesosoma. Three species, Conostigmus ballescoracas Dessart, 1997, C. babaiax Dessart, 1996 and C. longulus Dessart, 1997, are redescribed. Females of C. longulus are described for the first time, as are nine new species: C. bucephalus Mikó and Trietsch sp. nov., C. clavatus Mikó and Trietsch sp. nov., C. fianarantsoaensis Mikó and Trietsch sp. nov., C. lucidus Mikó and Trietsch sp. nov., C. macrocupula, Mikó and Trietsch sp. nov., C. madagascariensis Mikó and Trietsch sp. nov., C. missyhazenae Mikó and Trietsch sp. nov., C. pseudobabaiax Mikó and Trietsch sp. nov., and C. toliaraensis Mikó and Trietsch sp. nov. A fully illustrated identification key for Malagasy Conostigmus species and a Web Ontology Language (OWL) representation of the taxonomic treatment, including specimen data, nomenclature, and phenotype descriptions, in both natural and formal languages, are provided.

Abstract
The wings of butterflies and moths consist of dorsal and ventral epidermal surfaces that give rise to overlapping layers of scales and hairs (Lepidoptera, "scale wing"). Wing scales (average length ~200 µm) are homologous to insect bristles (macrochaetes), and their colors create the patterns that characterize lepidopteran wings. The topology and surface sculpture of wing scales vary widely, and this architectural complexity arises from variations in the developmental program of the individual scale cells of the wing epithelium. One of the more striking features of lepidopteran wing scales are the longitudinal ridges that run the length of the mature (dead) cell, gathering the cuticularized scale cell surface into pleats on the sides of each scale. While also present around the periphery of other insect bristles and hairs, longitudinal ridges in lepidopteran wing scales gain new significance for their creation of iridescent color through microribs and lamellae. Here we show the dynamics of the highly organized F-actin filaments during scale cell development, and present experimental manipulations of actin polymerization that reveal the essential role of this cytoskeletal component in wing scale elongation and the positioning of longitudinal ribs.

Abstract
The two epithelial monolayers of the insect wing undergo striking morphogenetic changes during the course of adult development, but the exact interactions between these monolayers were not evident until the ultrastructure of the cells was carefully examined. The interaction of the dorsal monolayer with the ventral monolayer continually changes as the two initially separate monolayers first lose their pupal basal laminae and then come together along a sharp interface to form microtubule-associated junctions. As blood space between the two monolayers expands 2 days later, new adult basal laminae and cuticle form. Concomitantly the epithelial cells stretch along their apicobasal axes to create a thin cellular M layer halfway between the dorsal and ventral surfaces of the wing that represents the site where connections between the monolayers are maintained at specialized basal junctions. The elongated processes of each monolayer that make up this M layer first fasciculate and then span the space separating the two monolayers, but only at relatively widely-spaced intervals. During later stages of adult development, dense aggregates of microtubules appear in these epithelial processes and presumably contract as cells dramatically shorten along their apicobasal axes during expansion of the wing. Examination of the ultrastructure of the developing adult wing has revealed how certain cellular events can account for the mechanics of cuticle and wing expansion after adult emergence.

Abstract
Cells in developing embryos behave according to their positions in the organism, and therefore seem to be receiving 'positional information'. A widespread view of the mechanism for this is that each cell responds locally to the concentration level of some extracellular chemical which is distributed in a spatial gradient. For molecules conveying and receiving the positional signal, concentrations are likely to be low enough that, per individual cell, only a few thousand molecules may be involved. Fluctuations to be expected in these numbers (Poisson distribution) could readily lead to errors up to a few percent of embryo length in the reading of position. This is an intolerable level of error for some developmental pattern-forming events. Embryos must have means of suppressing such errors. We maintain that this requires communication between cells, and illustrate this by using the reaction part of two well-known Turing-type reaction-diffusion models as the local gradient reader. We show that switching on diffusion in these models leads to adequate suppression of positional errors.

Abstract
In most developmental systems, gap junction-mediated cell-cell communication (GJC) can be detected from very early stages of embryogenesis. This usually results in the entire embryo becoming linked as a syncytium. However, as development progresses, GJC becomes restricted at discrete boundaries, leading to the subdivision of the embryo into communication compartment domains. Analysis of gap junction gene expression suggests that this functional subdivision of GJC may be mediated by the differential expression of the connexin gene family. The temporal-spatial pattern of connexin gene expression during mouse embryogenesis is highly suggestive of a role for gap junctions in inductive interactions, being regionally restricted in distinct developmentally significant domains. Using reverse genetic approaches to manipulate connexin gene function, direct evidence has been obtained for the connexin 43 (Cx43) gap junction gene playing a role in mammalian development. The challenges in the future are the identification of the target cell populations and the cell signaling processes in which Cx43-mediated cell-cell interactions are critically required in mammalian development. Our preliminary observations suggest that neural crest cells may be one such cell population.

Abstract
In bilateral animals, the left and right sides of the body usually present asymmetric structures, the genetic bases of whose generation are still largely unknown [CIBA Foundation (1991) Biological Asymmetry and Handedness, CIBA Foundation Symposium 162 (Wiley, New York), pp. 1-327]. In Drosophila melanogaster, mutations in the rotated abdomen (rt) locus cause a clockwise helical rotation of the body. Even null alleles are viable but exhibit defects in embryonic muscle development, rotation of the whole larval body, and helical staggering of cuticular patterns in abdominal segments of the adult. rotated abdomen is expressed in the embryonic mesoderm and midgut but not in the ectoderm; it encodes a putative integral membrane glycoprotein (homologous to key yeast mannosyltransferases). Mesodermal cells defective in O-glycosylation lead to an impaired larval muscular system. We propose that the staggering of the adult abdominal segments would be a consequence of the relaxation of intrinsic rotational torque of muscle architecture, preventing the colateral alignment of the segmental histoblast cells during their proliferation at metamorphosis.

Abstract
In higher Diptera, two nests of diploid cells called the ventral histoblasts, located one on either side of each abdominal segment among the polytene larval epidermal cells, give rise to the sternite and its surrounding pleura. During metamorphosis of the insect, these two groups of cells migrate and meet with each other in the midventral region of the developing adult. The cuticular pattern elements and pigmentation in the fifth sternite of the male housefly, when compared to those of other segments as well as the tergites of both sexes, are quite distinct. The above-mentioned features, coupled with the smaller number and predictable occurrence of one of the pattern elements in this sternite, viz, the primary forceps, help one to determine the developmental potential of the histoblast nest and the regulation of its potential which occur at the time of fusion of the two contralateral nests of this segment. A simple operation of slitting the larval epidermal cells (LEC) in a hemisegment in the vicinity of the histoblast nest or extirpation or rotation of a small rectangular piece of LEC between the ventral nest and the midventral line produced pattern abnormalities including mirror image duplication in the hemisternite. An analysis of these pattern abnormalities in the different segments and, in particular, in the fifth segment provides a dynamic picture of the formation of the median sternite. Further, these abnormalities indicate the significance of the presence of the intervening pleural cells between the confronting hemisternites under experimental conditions. Thus, each of the fifth ventral nests has the developmental potential to form more than half of the final sternite pattern. Possible mechanisms for the formation of the normal median sternite during metamorphosis and for the formation of duplicated hemisternites and their fusion products under experimental conditions are discussed in light of current models of pattern regulation.

Abstract
In Drosophila melanogaster mutant alleles of the segmentation gene wingless fall into two classes: winglessLethal mutations are embryonic lethals with a segment-polarity phenotype; the wingless1 mutation is viable when homozygous and produces a homeotic transformation in adults. This paper further describes the embryonic lethal phenotype, and also pole-cell transplants, experiments with a temperature-sensitive mutation, and clonal analysis with a winglessLethal mutation. It is argued that the wg gene is zygotically required after gastrulation for the normal patterning of each embryonic segment. The gene is still required in the larval stages, and the cell nonautonomy of this function supports the view that the wg gene product may be involved in intercellular signaling during development.

Abstract
The insect integument displays planar tissue polarity in the uniform orientation of polarized cuticular structures. In a body segment, for example, the denticles and bristles produced by the constituent epidermal cells point posteriorly. Colchicine can abolish this uniform orientation while still allowing individual cells to form orientated cuticular structures and thereby to express cell polarity. This suggests that an individual cell in a sheet can establish planar polarity without reference to some kind of covert supracellular cue (such as a morphogen gradient) in the epidermis as a whole. The results also indicate that colchicine interferes - directly or indirectly - with the mechanisms involved in aligning the polarity axes of individual cells into a common orientation, thereby generating supracellular or tissue polarity.

Abstract
The integument of an insect segment displays two distinct pattern features which are based on different properties of the constituent epidermal cells. Normally, the uniform orientation of epidermal cell polarities ("polarity pattern") is strictly correlated with the sequence of differentiated cells ("differentiation pattern"). Here it is reported that in the integument of the cotton bug Dysdercus epidermal cells can adopt orientations that do not correlate with the pigmentation pattern and which are not compatible with the gradient model. The results indicate that different features of a composite pattern can be independently controlled.

Abstract
Embryos hemizygous for armadillo produce a "segment polarity" phenotype in which the naked posterior two-thirds of each segment is replaced by denticles with reversed polarity. Small patches of homozygous arm cells induced by mitotic recombination also form such denticles, indicating that the changes in cellular fate observed in homozygous arm embryos are autonomous at the level of single cells. Clonally derived arm patches do not, however, show the characteristic arm polarity reversals, arguing that this feature of the phenotype depends on cell interactions in fully mutant embryos. Few, if any, clones were found in the posterior-most regions of the naked cuticle, and none were found in the posterior compartments of the thorax.

Abstract
An easy and sensitive method is reported here for testing the similarities of individual patterns by photographically transforming maps of these patterns to given, deductively chosen conventions involving constant distances between selected reference points. A cumulative map is produced by loading all landmarks from a set of individual maps on to one sheet of paper. The use of various a priori conventions results in variable cumulative maps, which are then optically transformed on an analog digital converter, with additional input for optical picture processing. The densitometrical maps thus obtained may be compared as to the cumulative degree of areas of maximal and minimal density of landmarks. The best conventions are those that yield the map with the most contrast.Maps of spatial patterns of the sites of contractile vacuole pore (CVP) primordia in an early stage of divisional morphogenesis of the ciliateChilodonella steini were compared after four different transformations and adjustments of the same set of individual maps. The best focusing of the sites of CVP differentiation was achieved by use of the postoral axis, defined by the center of the oral apparatus and the posterior end of the cell as the scaling parameter. The composite "domain map" obtained by optical transformation of this cumulative map could distinguish the specific CVP territories observed in earlier work (Kaczanowska 1981). These results confirm earlier findings that indicated the site of the oral apparatus is an important reference point in CVP primordia positioning. They also strongly suggest the existence of an overriding "scaling factor" governing the positioning of sites of differentiation in both dimensions of the developmental field. The method of superposition and scaling of pattern maps is generally applicable to situations in which pattern elements appear at discrete points on a flat surface.
