The Paragenital Organ of Stylopidae (Insecta: Strepsiptera) and the Functional Incorporation of the Secondary Larval Exuvia

Females of the insect order Strepsiptera are known to be traumatically inseminated. Traumatic insemination is the process of insemination by sperm transfer through a wound inflicted by the male in the female's integument, rather than by the male transferring sperm through the female's genital opening.…

Et latet et lucet: Discoveries from the Phyletisches Museum amber and copal collection in Jena, Germany

As the only direct records of the history of evolution, it is critical to determine the geological source of biota-bearing fossils. Through the application of synchrotron-radiation micro-computed tomography (SR-μ-CT), Fourier-transformed infrared-spectroscopy (FT-IR), visual evaluation of ultraviolet…

The reproductive and mating strategies of the twisted-winged parasites (insecta: Strepsiptera) : novel insights in the reproductive…

Die nur 600 Arten umfassende und damit Insektenordnung der Strepsiptera hat viele ungewöhnliche biologische Merkmale, wie die endoparasitische Lebensweiße der meisten Weibchen oder einen extrem ausgeprägten Sexualdimorphismus. Die wohl bizarrste und gleichzeitig umstrittenste Eigenschaft ist die traumatische…

The morphology of the free‐living females of Strepsiptera (Insecta)

The morphology of the adult free‐living females of Mengenilla moldrzyki and Eoxenos laboulbenei (Strepsiptera, Mengenillidae) was documented with µCT‐based 3D reconstructions and histological serial sections. External and internal features of both species are characterized by far‐reaching specialization…

Beetles going underground : morphological adaptions linked with subterranean habits

Aims of the present study were: (1) a thorough morphological documentation of the head and thorax of selected representatives of two coleopteran families with subterranean species; (2) to analyze the effects of the environment based on comparisons of external and internal structural features of species…

The evolution of ant (Hymenoptera: Formicidae) : head morphology

Ants are the most speciose group of eusocial insects. Species of the family Formicidae are dominant in most terrestrial ecosystems and different ant species have widely different life habits. As diverse as ant lifestyles are also their body forms. This diversity is well documented in the systematic,…

Polyneopteran head morphology and its phylogenetic implications

Polyneoptera beinhaltet zehn traditionelle Insektenordnungen mit so diversen Vertretern wie sozialen Termiten, räuberischen Gottesanbeterinnen oder phytophagen Stab- und Gespenstschrecken. Die Verwandtschaftsverhältnisse zwischen den einzelnen Gruppen sind bisher vollkommen ungeklärt. Die vorliegende…

The evolution of the female postabdomen and genitalia in mecopterid insects (Insecta: Mecopterida)

Das weibliche Postabdomen und die inneren Abschnitte des Genitalsystems von 15 Vertretern der mecopteriden Insekten wurden einer detaillierten Untersuchung unterzogen. Bei der Auswahl der Taxa wurden innerhalb der einzelnen Insektenordnungen basal abzweigende Vertreter besonders berücksichtigt. Es wurden…
