Dictyoptera is a genus of the red- capped beetle family(Lycidae) with a Holarctic distribution. The almost 20 species (according to today's genus delimitation) are predominantly distributed in East Asia. The genus includes a species with a very wide distribution that is also found in Central Europe, the scarlet net beetle Dictyoptera aurora . The other species previously specified from Western and Central Europe are now assigned to other genera.

features

They are slender, cylindrical, almost parallel-sided beetles. They are usually, like many related genera, colored black with a red pronotum and red elytra , in some species with darker drawing elements, often with a central or between red keels dark pronotum. The short head is hidden under the pronotum when viewed from above. In both sexes, the antennae are either thread-like (filiform) or weakly serrated (serrat), with the flagellum limbs slightly triangular. The pronotum usually has five dimples (areola) separated by keel-shaped ridges, and a middle, rhombic areola is always present. The elytra always have nine longitudinal keels or ribs called costae, in most species four stronger primary keels and five more delicate secondary keels can be distinguished, with transverse keels resulting in a grid-like structure.

ecology

As far as is known, all species live in forests, with North American and European species preferring conifers. The ecology of the East Asian species is unknown.

Taxonomy

The genus Dictyoptera is a type of the tribe Dictyopterini . There are two views about belonging in subfamilies. While most authors assign them to the Erotinae, other authors split them into several subfamilies and then assign them to the subfamily Dictyopterinae. A synonym of the generic name is Dictyopterus Mulsant, 1838.

The genus includes four species in North America. There is only one species in Europe, Dictyoptera aurora . The other species previously included in the genus (in Kleine in 1942 there were 40 species, 11 of which were Palearctic) have now been assigned to other genera. The main distribution area of ​​the genus is probably in East Asia, in the mountains of Laos and Vietnam, from where new species are regularly described.
