Abstract
For more than 100 years it has been known that the sclerotised median lobe of beetles harbours a membranous structure (the "internal sac" or "endophallus") which is everted during copula inside the female genital tract. In order to explore the functional role of this structure and those associated with it, we cryofixed copulating pairs of Donacia semicuprea and Lilioceris lilii and studied the relative position of the elements of the copulatory apparatus of males and females by micro-computer-tomography. We found that the everted endophallus fills the lumen of the bursa copulatrix completely. Our data suggest that in Lilioceris lilii the tip of the sclerotised distal part of the ejaculatory duct, the flagellum, is positioned exactly over the opening of the spermathecal duct inside the bursa copulatrix. The mouth of the bursa copulatrix in Donacia semicuprea is armed with a strong muscle ring, and the whole wall of the bursa is covered externally with a layer of muscle fibres. These morphological differences correspond with differences in mating behaviour: In reed beetles (Donaciinae), females seemingly can control mating to a higher degree than in lily beetles (Lilioceris spp.).

Copulatory linking of male and female genitalic structures in 11 Neotropical species of Chrysomelidae and one species of Megalopodidae was studied by freezing and then dissecting pairs of beetles in copula. In Megalopus armatus (Megalopodidae) the male has a long endophallus with complex membranous protuberances and a terminal flagellum that probably reaches the spermatheca. In the subfamily Eumolpinae the females have telescoping ovipositors through which the male endophalli pass, reaching to o...

Beetle genitalia are usually described only for taxonomic purposes without considering the possible function of structures. Exceptions are sporadic detailed studies on single species. We studied genital structures in the subfamilies of Cerambycidae and outlined assumptions on the function of these structures and the implications for the phylogeny of the Cerambycidae. We found that male genitalia in particular are taxon-specific on a higher taxonomic level; e.g., the parameres are widely variable...

The male copulatory organ (aedeagus) of the Curculionoidea and the Chrysomeloidea is originally composed of a median lobe and a tegmen with basal struts and distal parameres. Within the Phytophaga (=Pseudotetramera), the parameres have been reduced several times. Comparison of different types of parameres, median lobes, aedeagi lacking parameres, and investigation of dissected pairs in copula revealed that (1) parameres do not provide mechanical coupling, (2) mechanical footing is provided by th...

Parameres, or lateral lobes, of the male copulatory organ are present in many insect groups, while in others they are reduced or completely lacking. Nearly all long-horned beetles have parameres, while only the leaf beetle sub- taxa Megalopodinae, Zeugophorinae, Orsodacninae, Bruchidae, Sagrinae, Donaciinae and the genus Timarcha possess them. In these taxa, parameres can consist of one or two lobes, can be very long or quite short, and the number and den- sity of their setae can vary. Based on ...

If I see a number of keys, of very minute and elaborate workmanship, all different, I cannot doubt that every one is intended to fit some special lock . . . and this conviction is the stronger, the more varied and the more complex are the keys. We cannot withhold a hearty assent to the conclusion of one of the most eminent of modem physiologists, who, speaking of these organs in the class of Insects generally, says, "They prevent allied species from producing bastards by adulterous connexions; f...

Abstract The reproductive morphology of the economically important Argentine stem weevil, Hyperodes bonariensis Kuschel, is described. A method for external differentiation of the sexes is described, and the functional morphology of the genitalia of both sexes is discussed.

ABSTRACT The copulatory organs of male insects are generally complex, species-specific arrangements of hardened sclerotized plates bound together by flexible, less sclerotized cuticle. Their extensive morphological diversification is a recurrent pattern in the evolutionary radiation of animals, yet a clear consensus as to what selection pressures drive this divergence is still to emerge. In part, this stems from the fact that the function of individual sclerites that integrate to form the aedeag...

In the seed beetle Callosobruchus maculatus, the male intromittent organ is covered in sharp spines that pierce the female copulatory tract wall during mating. Although the fitness consequences of traumatic mating are well studied in this species, we know much less about how the male and female genitalia interact during mating. This is partly due to the fact that genital interactions occur primarily inside the female, and so are difficult to observe. In this study, we use X-ray micro-CT scanning...

We investigated probable functions of the interacting genitalic components of a male and a female of the flightless grasshopper species Melanoplus rotundipennis (Scudder, 1878) (frozen rapidly during copulation) via correlative microscopy; in this case, by synergizing micro-computed tomography (micro-CT) with digital single lens reflex camera photography with focal stacking, and scanning electron microscopy. To assign probable functions, we combined imaging results with observations of live and ...
