“…Morphometric analysis of insect wings has been used to distinguish the relationship between closely related taxa (Brown & Shipp, 1977, 1978Brown, 1979;Rohlf & Archie, 1984;Byers, 1989;Yu et al, 1992;Kukalova-Peck & Peck, 1993;Ansorge, 1994;Diniz-Filho & Malaspina, 1995). Further, morphometric wing analysis can differentiate among populations within a species.…”

Differences in wing morphology are described for three Eurasian populations of Drosophila lummei. A truss network of wing characters was used to quantify wing size and shape for 149 individuals from Japan, Sweden and Russia. Sexual dimorphism in wing size and shape was not substantial, so the sexes were pooled and multivariate analyses conducted. Both principal components analysis and discriminant analysis of wing morphology revealed signi®cant differences among all geographic groups. These differences indicate that morphometric analysis of wing characters can reliably discriminate between geographic groups and accurately classify individuals of the three Drosophila lummei populations. Principal components analysis also revealed that characters occurring in the same section of the wing formed correlated suites which corresponded to morphologically and functionally distinct areas of the wing. This study is unique because it detects subtle morphological differences within a single species of fruit¯y across an intercontinental distribution.The results corroborate genetic studies in which geographic variation was found for inversion polymorphisms among spatially separated populations of Drosophila lummei.

“…Wing morphometric divergence has already proved t o be useful in reconstructing bee phylogenies (Dupraw, 1965 ;Plowright & Stephen, 1973). The wing may be subject t o strong stabilizing selection, and this may help to partly explain the relatively low intraspecific variability and moderate interspecific changes in this character that was obtained in analysis of the Australian Luciliini (Brown & Shipp, 1977). The wing attributes were shown in that study to be unaffected by sex or generation, and could not be correlated with geographic distribution within the species.…”

Wing morphometric analysis of Australian Sarcophaginae (Diptera: Sarcophagidae)

Phenetic affinities of thirty‐two species of Australian Sarcophaginae are described. A set of wing morphometric characters was analysed using canonical variate analysis and clustering of generalized distances. The results were compared to classifications of Roback (1954) and to that of Souza Lopes (1954, 1958a, b, 1959). There was substantially more agreement with the classification of Roback than with that of Souza Lopes. Thus the subfamily appears to consist of a reduced number of minor genera (Heteronychia, Blaesoxipha, Tricharaea and possibly Sarcosolomonia/Fergusonimyia) and a large complex consisting of species of Sarcophaga sensu lato.

“…As Bryant (1977) indicated, although the shape component in the housefly, Musca domestica, was small, it could represent a broader genetic contrast in other muscoid Diptera. Sufficient modifications in venation patterns have been detected by morphometric methods to allow species separation, as for example in recent studies of the Australian Luciliini (Brown and Shipp 1977) and Sarcophaginae (Brown and Shipp 1978). An aim of the present study was to determine whether representative taxa of the closely related muscoid families Muscidae, Calliphoridae and Sarcophagidae, in which the venation patterns are more or less the same, can be distinguished morphometrically also, where this morphometric differentiation has occurred and, what are the patterns and extent of the phenetic variation among and within the examined taxa.…”

“…These workers, as did Greenham and Hughes (1971), related the increasing ratio to a north-south cline in broad bands of longitude. However, when several populations of the blowfly Lucilia cuprina were examined using wing morphometrics, the populations, although distinguishable, could not be related to any clinal attern (Brown and Shipp 1977).…”

Canonical variate analysis and the generalized distance Dz statistic are useful ways of analyzing within and between variation in species. Little attempt has been made previously to quantify and assess the variation in calyptrate Diptera other than in descriptive terms. In this study, the variation was assessed for 11 species of muscoid Diptera and populations of the five calliphorid species were analyzed in greater detail. Nine morphometric characters of the wing were used. Most of the variance (937:) fell in the first three canonical variates for the species comparison. and emphasised shape atrributes. although size was important. In particular. the position of vein R , . humeral vein 11. and the discal cell suggested that the sarcophagid flies formed an intermediate group between the calliphorid and muscid flies examined. Size components were more important than shape components within species. and these differences between populations could not be related to a geographic cline. IntroductionIn this study, the similarities between several species of muscoid flies are examined with respect to wing characters. The examination of character variation within a single functional "organ" system can provide much information in closely related taxa. It could be argued that the wing reflects much of the evolutionary history of the group, the shape being relatively stable unlike size which can be influenced by nongenetic factors. It is from studying patterns of character variation in populations, including geographic variation, that an insight into relationships between those populations may be gained. Many workers have previously assessed single character variation over geographic range by univariate methods, but increasingly, groups of characters are being assessed simultaneously using multivariate techniques (Sokal 1965;Gould and Johnston 1972;Thorpe 1976). Shape factors especially, because they reflect more complex interaction, can only be adequately assessed by using multivariate methods that simultaneously consider the variation of many characters (Atchley 1971 ; Atchley and Hensleigh 1974). Further, as adaptations of populations are multidimensional, variation within and between taxa may be better resolved by using such multivariate methods as canonical variate analysis (= multiple discriminate function analysis). This type of intra-specific variation analysis is carried out with diverse aims, for it can be used to describe variation patterns of a species, or to subdivide a variable species into subspecific units, thereby gaining an insight into the evolutionary forces acting upon a species (Sokal 1965). The multivariate analysis allows for the efficient summarization of large data sets so that populations or species may be compared or contrasted using fewer metrics. Effectively data sets representing the morphology of taxa can be expressed as a single data point in multivariate hyperspace. Biological interpretation is made from the relative positions and distances between these data points.In wings of di...
