Spermatophoresand Spermatophore Producing Internal Organs of Cleridae (Coleoptera: Clerinae): their Biological and Phylogenetic Implications

Wildland fire in ecosystems: effects of fire on soils and water

“…Still other adaptations appear to have evolved primarily in response to fire and can involve the complex long-term evolution of some rather esoteric anatomical features. For example, a recent study on detailed morphological and anatomical characteristics of a subfamily of beetles (Coleoptera: Clerinae) suggests that these invertebrates evolved thermoreceptor antenna, which enable the beetles to avoid death by fire in xeric environments (Opitz 2003). The evolution of this feature occurred over a span of tens of thousands of years.…”

Absence asymmetry: The evolution of monorchid beetles (Insecta: Coleoptera: Carabidae)

“…Given the number of insect species, relatively few publications present comparative descriptions of the gross morphology of insect testes and male accessory glands (Dufour, 1825;Bordas, 1900;Matsuda, 1976;Suzuki, 1988;Vats and Vasu, 1993;de Marzo, 1992de Marzo, , 1996Gillott, 2003;Opitz, 2003), although many publications provide isolated descriptions of male structures for individual species. Two forms of coleopteran testes are known: a single, tubular, coiled follicle in the suborders Adephaga and Myxophaga (Reichardt, 1973;Lawrence and Britton, 1994;questionable in Myxophaga, R. Beutel pers.…”

Anatomy of the Spermatophore in Triatomines (Hemiptera, Reduviidae, Triatominae) and Its Applications to the Study of Chagas Disease Vector Biology

“…Thus, the lumen of the vagina is responsible for giving the definitive format to the spermatophore, such as in Coleoptera. 7 In the present study, it was observed that, when the insects spent a long time fasting, copulation did not take place in either of the species studied given that the main element of spermatophore composition involves secretions from the accessory glands. 7,23 We took the view that this structure represented a substantial investment of energy by the male and was a trophic source when food was scarce, which could have an influence on reproduction.…”

“…19 In the present study, the spermatophores extracted from the vagina of the female are similar to other spermatophores described for other insect species. 7,20,21 In T. infestans, the secretions from the spermatophore are completely translucent, whereas in R. neglectus, the posterior region is opaque, thus indicating that it is part of the opaque gland secretion described in R. prolixus.…”

“…The development of a more spacious spermatheca and an expanded vagina can be adapted to receive nutrients secreted and also allow a prolonged stock sperm. 7 The females of many species digest, eat, or remove the spermatophore after it has been transferred. Thus, it has been proposed that the spermatophore size remains large as a form of parental investment.…”
