Insect genitals vary greatly among species and provide a key tool for species-level
taxonomy. Insects differing in the genitalia are often treated as discrete, reproductively …

Genital morphology shows peculiar patterns of variation among insect species. Traditionally,
genital species specificity has been assumed to serve as a mechanical isolation system …

Asymmetries are a pervading phenomenon in otherwise bilaterally symmetric organisms
and recent studies have highlighted their potential impact on our understanding of …

Insect genital characters are extensively used in species level taxonomy, and their value in
species delimitation is great. Based on the lock-and-key hypothesis and that genital …

In species of several insect orders and spiders, it has been shown that the size of male
genitalia relative to body size decreases as the body becomes larger (negative allometry) …

Male genitalia evolve through sexual selection and, in insects, tend to show negative static
allometry, low phenotypic variation, and are usually relatively small. Much less is known …

Genital asymmetry is a recurring phenomenon in insect morphology and current data
suggest that it has arisen multiple times independently in several neopteran orders. Various …

While species-specificity of male genitalia is a well-documented pattern among insects
which can be explained by sexual selection, there are a number of species that appear to …

The genitalia of male and female Lepidoptera are complex organs, composed of several
structures that exhibit great diversity of shapes, sizes, and positions, suggesting that they …

Male genitalia show patterns of divergent evolution, and sexual selection is recognised as
being responsible for this taxonomically widespread phenomenon. Much of the empirical …
