Resumo: A bibliographic revision of sexual dimorphism in different families of Collembola was performed in order to determine the most common patterns in each group. We list several examples of the sexual dimorphism in different families of Collembola, which illustrate from some of the smallest differences between males and females to major differences between both sexes in some families. We show different cases of sexual dimorphism in Spinactaletes, Sminthurides, and the remarkable morphology of Guthriella muskegis. It seems that most of the cases of strong sexual dimorphism are related to aquatic habitats or behaviour still not fully understood. Species belonging to primarily aquatic families (fresh water or marine water) have the most evolved morphology, where males have clasping antennae to attach the females in order to avoid loosing them with the movement of the water.

No obstante, en Symphypleona hay algunas especis que muestran diferencias muy obvias entre los sexos, entre las que se incluyen el color, la presencia de glánulas, y, en los machos, la modificación de las antenas en una órgano prensil. En el presente trabajo, se presentan diversos ejemplos del dimorfismo sexual en diferentes familias de Collembola. Estos ejemplos ilustran desde pequeñas diferencias entre machos y hembaras, hasta las grandes diferencia spresentes entre ambos sexos en algunas familias. Presentamos diferentes casos de dimorfismo sexual en Spinactaletes, Sminthurides y, uno de los casos más extraordinarios, el de Guthiella muskegis. En la mayoría de los casos, el alto dimorfismo sexual está relacionado con el hábitat acuático o comportamientos aún no estudiados. Especies pertenecientes a familias primordiarmente acuáticas (de agua dulce o marina) tienen un mayor dimorfismos, con las antenes de los machos que sierven de órganos prensiles para asir a la hembra y evitar que se suelten con el movimiento del agua.Uma revisão bibliográfica do dimorfismo sexual em diferentes famílias de Collembola foi feita para determinar os padrões morfológicos mais comuns em cada grupo. Foram listados diversos exemplos de dimorfismo sexual em diferentes famílias de Collembola, que ilustram desde as menores diferenças entre machos e fêmeas até as grandes diferenças entre os sexos em algumas famílias. Foi mostrado o dimorfismo sexual em Spinactaletes e Sminthurides, e a morfologia marcante de Guthriella muskegis foi documentada. É provável que a maioria dos exemplos mais evidentes de dimorfismo sexual estejam relacionados ao habitat aquático ou a padrões de comportamento ainda não compreendidos. As espécies que pertencem às famílias aquáticas primárias (água doce ou água marinha) são as que têm morfologia mais evoluída. Os machos têm antenas preênseis, para agarrar as fêmeas e evitar que se desprendam com o movimento da água.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraPalacios-Vargas, José GuadalupeCastaño-Meneses, Gabriela2010-11-26info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/1256Pesquisa Agropecuaria Brasileira; v.44, n.8, ago. 2009: Thematic Issue XV International Colloquium on Soil Zoology and XX Colloquium on Apterygota; 959-963Pesquisa Agropecuária Brasileira; v.44, n.8, ago. 2009: Thematic Issue XV International Colloquium on Soil Zoology and XX Colloquium on Apterygota; 959-9631678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/1256/5789https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/1256/2201https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/1256/2202https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/1256/2203https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/1256/2204https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/1256/2205info:eu-repo/semantics/openAccess2012-06-17T11:52:07Zoai:ojs.seer.sct.embrapa.br:article/1256Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2012-06-17T11:52:07Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
