What does the morphological diversity of siphunculi tell us about the evolution of aphids (Insecta, Hemiptera, Aphidoidea)?

Aphids are soft-bodied insects living predominately in temperate climates, presenting a wide variety of adaptations to utilize plants as a source of food as well as involvement in various relations with other organisms, including bacteria and other insects. Being known from the Mesozoic, insufficien...

Description
Summary:Aphids are soft-bodied insects living predominately in temperate climates, presenting a wide variety of adaptations to utilize plants as a source of food as well as involvement in various relations with other organisms, including bacteria and other insects. Being known from the Mesozoic, insufficient fossil data still pose some difficulties in establishing the course of evolution of their morphological adaptations. Here, we describe a new fossil genus and species from the Later Jurassic, equipped with a special morphological structure typical of modern aphids – siphunculi. Reviewing data on the morphology of siphunculi, we make an attempt to establish a course of evolution of aphids, leading to the development of this particular structure that is – extremely diverse in recent taxa of the subfamily Aphidoidea.
