Traumatic Insemination in the plant bug genus Coridromius (Heteroptera: Miridae) Nik Tatarnic University of Sydney & Australian Museum

Q. What is Traumatic Insemination? A. Male punctures female with hypodermic genitalia, injects sperm into body cavity

Q. Why Practice Traumatic Insemination? A. Thought to be a means for males to circumvent female mating resistance

Q. Why Resist Mating? A. Males and Females have differing reproductive optima = Sexual Conflict

Coercive mating in waterstriders Westlake Rowe & Currie (2000)

Crudgington, H.S. and Siva-Jothy, M.T. (2000) Genital Damage in Bean Weevils

Sexual Conflict Coevolutionary Arms Race Males evolve structures and behaviours which increase their own fitness, but reduce female fitness Females evolve structures and behaviours to mitigate costs

e.g. Traumatic Insemination & Paragenitalia Sexual Conflict Coevolutionary Arms Race Males evolve structures and behaviours which increase their own fitness, but reduce female fitness Females evolve structures and behaviours to mitigate costs

Who are the Traumatic Inseminators? Non-insect invertebrates: rotifers, acanthocephalans, pinworms, gastropod snails, free-living flatworms Insects: Strepsiptera, Cimicomorpha (Heteroptera) e.g. Bedbugs

Enough biogeography – back to the sex!

Conclusions II Female paragenitalic evolution does not follow a simple transition series Instead, multiple independent cases of elaborate paragenital development = Strong sexual selection

Summary Traumatic Insemination has evolved at least 3 times in the Cimicomorpha TI drives elaborate female morphology in Coridromius Question: What predisposes Cimicomorpha to such deviant sexual practices?
