Gynandromorphism and intersexualism in Culicidae (Diptera: Culicomorpha: Culicoidea): description of five individual cases and a literature review


Kronefeld, M; Schaffner, F; Kampen, H; Werner, D (2013). Gynandromorphism and intersexualism in Culicidae (Diptera: Culicomorpha: Culicoidea): description of five individual cases and a literature review. Studia dipterologica, 20(2):239-253.

Abstract

Although very rare under natural conditions, anomalies of phenotypic sexual expression have been described for individuals of numerous families of the Diptera, including mosquitoes (Culicidae). Gynandromorphism and intersexualism are sexual aberrations generating individuals either with both male and female or with intermediate sexual characteristics. Here we describe five cases of gynandromorphism in three mosquito species. In addition, a list of species of the family Culicidae for which gynandromorphs and intersexes have been described in the literature is compiled.

Anomalien der phänotypischen Geschlechtsausprägung sind bei einer Vielzahl von Dipterenfamilien, einschließlich Stechmücken (Culicidae), beschrieben, kommen jedoch unter natürlichen Bedingungen sehr selten vor. Gynandromorphismus und Intersexualismus sind sexuelle Fehlentwicklungen, aus denen entweder Individuen mit männlichen und weiblichen oder Individuen mit intermediären sexuellen Merkmalen hervorgehen. Fünf Fälle von Gynandromorphie bei drei Stechmückenarten werden präsentiert. Zusätzlich wird eine Liste der Arten der Familie Culicidae, bei welchen Gynander und Intersexe in der Fachliteratur beschrieben wurden, zusammengestellt.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
