Circulatory organs of Diplura (Hexapoda): the basic design in Hexapoda?

International Journal of Insect Morphology and Embryology, 1999
Abstract The circulatory systems of Campodea augens and Catajapyx aquilonaris (Hexapoda: Diplura) have been examined by means of light and electron microscopy. Hemolymph flow has also been investigated in vivo. Both species share features that deviate conspicuously from the common textbook design of the insect circulatory system: (i) antennal vessels

The phylogeny of Strepsiptera (Hexapoda)

Cladistics, 2005
AbstractPrevious phylogenetic analyses of Strepsiptera have been limited to characters from only males or first instar larvae, and by poor taxonomic sampling. This investigation is the first cladistic analysis to use more than fourfold as many characters as any prior study, and a broader sampling of taxa. The analysis of 189 morphological characters of

How are the mitochondrial genomes reorganized in Hexapoda? Differential evolution and the first report of convergences within Hexapoda

Gene, 2021
The evolution of the Hexapoda mitochondrial genome has been the focus of several genetic and evolutionary studies over the last decades. However, they have concentrated on certain taxonomic orders of economic or health importance. The recent increase of mitochondrial genomes sequencing of diverse taxonomic orders generates an important opportunity to ...

Insecta (= Hexapoda), Insekten

2014
Die Insecta (Insekten) stellen mit fast einer Million beschriebener Arten etwa zwei Drittel aller bekannten Species des Tierreichs. Allein in Mitteleuropa wurden uber 30 000 Arten nachgewiesen. Entsprechend dieser riesigen Formenfulle ist ihre Bedeutung sehr vielfaltig, teils sehr negativ, meist jedoch positiv.

Springstaarten op korstmossen (Hexapoda: Collembola).

Nederlandse Faunistische Mededelingen, 2003
Springtails on lichens (Hexapoda: Collembola) From September 1999 until June 2002 an inventory was made of lichens in the Netherlands. Overall, 53 species of lichens, spread over 63 locations were sampled. When these lichens were prepared for deposition in a reference collections the springtails crawling out were collected and identified to the species

Hexapoda: A Drosophila’s View of Development

2015
By any criterion, Insecta (as a subtaxon of Hexapoda) is the most successful taxon on the planet (see Chaps. 2 and 3 for the inclusion of the various subtaxa in Hexapoda versus Insecta). The number of described insect species nears one million, and they are found in almost every ecosystem, forming the major component of animal biomass in most.

Overview on spermatogenesis and sperm structure of Hexapoda

Arthropod Structure & Development, 2014
The main characteristics of the sperm structure of Hexapoda are reported in the review. Data are dealing with the process of spermatogenesis, including the aberrant models giving rise to a reduced number of sperm cells. The sperm heteromorphism and the giant sperm exceeding the usual sperm size for length and width are considered.

Musculature abdominale des Acerentomidae (Hexapoda, Protura)

Bulletin de la Société entomologique de France, 2017
Une révision de la description de la musculature abdominale du Protoure Acerentomon affine Bagnall, 1912, a été entreprise. La comparaison avec celle des autres aptérygotes Entognathes montre des caractères dérivés : réduction du nombre de muscles et complexité de leur disposition.
