Several patterns of sexual shape dimorphism, such as male body elongation, eye stalks, or extensions of the exoskeleton, have evolved repeatedly in the true flies (Diptera). Although these dimorphisms may have evolved in response to sexual selection on male body shape, conserved genetic factors may have contributed to this convergent evolution, resulting in stronger phenotypic convergence than might be expected from functional requirements alone. I compared phenotypic variation in body shape in… 
Variation of sexual dimorphism of wing shape in the family Dolichopodidae (Diptera)
TLDR
The absence of a significant phylogenetic signal in seven out of nine studied wing points indicates that the sexual dimorphism in form evolved, at least partially, in each of the studied species.
Allometry constrains the evolution of sexual dimorphism in Drosophila across 33 million years of divergence
TLDR
The keys for disentangling alternative explanations for dimorphism evolution are studies of natural and sexual selection, together with a deeper understanding of how microevolutionARY parameters of evolvability relate to macroevolutionary patterns of divergence.
Evolution of sexual dimorphism of wing shape in the Drosophila melanogaster subgroup
TLDR
SShD in the Drosophila wing can evolve rapidly and therefore shows only weak phylogenetic structure, and the variable contribution of allometric and non-allometric components to the evolutionary divergence of SShD and the evolutionary plasticity of allometry suggest that S ShD and allometry are influenced by a complex interaction of processes.
Disentangling the Size and Shape Components of Sexual Dimorphism
TLDR
While in argiopines there was no clear association between SShD and SSD, a significant correlation in all orb weavers at the genus level is detected, suggesting that at certain phylogenetic levels SSD may be a prerequisite for SSD.
Sexual dimorphism and inter-individual variation in the rove beetle , Creophilus maxillosus L . ( Col : Staphylinidae )
TLDR
The results show that, particularly head size, mandible length and ocular distance are probably under sexual selection in males, while traits such as eye size are isometric to body size.
Sexual selection, phenotypic variation, and allometry in genitalic and non-genitalic traits in the sexually size-dimorphic stick insect Micrarchus hystriculeus
TLDR
A negative allometric scaling pattern and low phenotypic variation of clasper size is suggestive of stabilizing selection and supports the ‘one-size-fits-all’ hypothesis.
SEX‐SPECIFIC PATTERNS OF MORPHOLOGICAL DIVERSIFICATION: EVOLUTION OF REACTION NORMS AND STATIC ALLOMETRIES IN NERIID FLIES
TLDR
The findings reveal qualitative sex differences in patterns of morphological diversification, whereby shape–size relationships diversify extensively in males, but remain conserved in females despite extensive evolution of trait means.
The ventral cranial size and shape variation between males and females of European brown frogs: Rana dalmatina, R. graeca and R. temporaria (Anura, Amphibia)
TLDR
Patterns of ventral cranial size and shape variation between males and females of three species of European brown frogs, Rana dalmatina, R. graeca and R. temporaria, from the Balkan Peninsula are described to indicate that differential diet of males and Female can be a factor affecting observed sexual dimorphism patterns.
The Evolution of Condition‐Dependent Sexual Dimorphism
TLDR
The genetic mechanisms that give rise to multivariate sexual dimorphism in body shape thus function in a strongly condition‐dependent manner in this species, suggesting a common genetic basis for body shape variation within and between sexes.
The Evolution of Sexual Dimorphism: Understanding Mechanisms of Sexual Shape Differences
TLDR
Sexual dimorphism is a pattern seen throughout the animal kingdom and is exhibited in a myriad of ways, ranging from poeciliid fishes to dragon flies to eclectus parrots.

PHYLOGENETIC ANALYSIS OF SEXUAL DIMORPHISM AND EYE‐SPAN ALLOMETRY IN STALK‐EYED FLIES (DIOPSIDAE)
TLDR
Overall, eye‐span allometry exhibits significantly more change on the phylogeny than the other morphological traits, and this pattern is consistent with recent models that predict a strong relationship between sexual selection and the variance of ornamental traits and highlights the significance of eye‐ span allometry in intersexual and intrasexual signaling.
SEXUAL SELECTION, GENETIC ARCHITECTURE, AND THE CONDITION DEPENDENCE OF BODY SHAPE IN THE SEXUALLY DIMORPHIC FLY PROCHYLIZA XANTHOSTOMA (PIOPHILIDAE)
TLDR
It is argued that condition dependence may weaken intersexual genetic correlations and facilitate the evolution of sexual dimorphism, and the role of sexual selection in the Evolution of condition dependence is supported, but considerable variation in condition dependence among sexual traits is revealed.
INTRALOCUS SEXUAL CONFLICT AND THE GENETIC ARCHITECTURE OF SEXUALLY DIMORPHIC TRAITS IN PROCHYLIZA XANTHOSTOMA (DIPTERA: PIOPHILIDAE)
TLDR
The genetic architecture of sexual and nonsexual morphological traits in Prochyliza xanthostoma is investigated and theory suggests that intralocus sexual conflict can be resolved substantially by genomic adaptation, but further work is required to identify the proximate mechanisms underlying these patterns.
The scaling and selection of sexually dimorphic characters: an example using the Marbled Teal
TLDR
It is shown how the scaling in Marbled Teal can be used to study the selective forces responsible for dimorphic morphological characters, using the monochromatic Marbling Teal Marmaronetta angustirostris as an example.

TLDR
Sexual dimorphism may result from natural and/or sexual selection, and systems of mating are often thought to evolve in response to ecological pressures, although mating preferences may be self-reinforcing.
Mating behavior and the evolutionary significance of mate guarding in three species of crane flies (Diptera: Tipulidae)
TLDR
Three species of crane flies-Dactylolabis montana, Limonia simulans, and Antocha saxicola-gather near streams to mate and oviposit and sperm competition appears to be intense and to follow last-male advantage, based on the packing of sperm within the two elongate spermathecae.
Trade‐offs during the Development of Primary and Secondary Sexual Traits in a Horned Beetle
TLDR
The results suggest that even distant body parts may rely on a common resource pool to sustain their growth and that the relative timing of growth may play an important role in determining whether, and how severely, growing organs will affect each other during development.
ORNAMENTS IN THE DIPTERA
TLDR
Several functions for ornaments are considered, including advertisement of genetic properties, subversion of female mate choice and “runaway” sexual selection.
THE EVOLUTION OF STATIC ALLOMETRY IN SEXUALLY SELECTED TRAITS
TLDR
An allocation trade-off model is presented that predicts the optimal pattern of allometry under different selective regimes and highlights the difficulty of inferring complex underlying processes from simple emergent patterns.
Resource Defense Mating System in Antlered Flies, Phytalmia spp. (Diptera: Tephritidae)
TLDR
Experiments in which various tree species were made available within the Phytalmia habitat revealed a limited number of host plant species and male-male interactions were frequent and differed between species in ways related to interspecific morphological differences.
