Two different patterns of wing venation are currently supposed to be present in each of the three orders of Paraneoptera. This is unlikely compared with the situation in other insects where only one pattern exists per order. We propose for all Paraneoptera a new and unique interpretation of wing venation pattern, assuming that the convex cubitus anterior gets fused with the common stem of median and radial veins at or very near to wing base, after separation from concave cubitus posterior, and re-emerges more distally from R + M stem. Thereafter, the vein between concave cubitus posterior and CuA is a specialized crossvein called "cua-cup," proximally concave and distally convex. We show that despite some variations, that is, cua-cup can vary from absent to hypertrophic; CuA can re-emerge together with M or not, or even completely disappear, this new interpretation explains all situations among all fossil and recent paraneopteran lineages. We propose that the characters "CuA fused in a common stem with R and M"and "presence of specialized crossvein cua-cup" are venation apomorphies that support the monophyly of the Paraneoptera. In the light of these characters, we reinterpret several Palaeozoic and early Mesozoic fossils that were ascribed to Paraneoptera, and confirm the attribution of several to this superorder as well as possible attribution of Zygopsocidae (Zygopsocus permianus Tillyard, 1935) as oldest Psocodea. We discuss the situation in extinct Hypoperlida and Miomoptera, suggesting that both orders could well be polyphyletic, with taxa related to Archaeorthoptera, Paraneoptera, or even Holometabola. The Carboniferous Protoprosbolidae is resurrected and retransferred into the Paraneoptera. The genus Lithoscytina is restored. The miomopteran Eodelopterum priscum Schmidt, 1962 is newly revised and considered as a fern pinnule. In addition, the new paraneopteran Bruayaphis oudardi gen. nov. et sp. nov. is described fromthe Upper Carboniferous of France (see Supporting Information).

“…Membracids are characterized by a pronotum that can show huge variation among species ( Funkhouser 1917 , Wood 1993a , Dietrich et al 2001 , Lin 2006 ). Among the roles suggested for this unique structure are crypsis (i.e., mimetism with the host plant or imitation of other insects) and defense (i.e., aposematism or mechanical barrier; Wood 1974 , 1993a ; Roy et al 2007 ). Chemical and mechanical cues are the most important signals mediating intraspecific (i.e., courtship, aggregation) and interspecific (i.e., mutualism with ants) communication ( Nault et al .…”

Biology and Ecology of Alchisme grossa in a Cloud Forest of the Bolivian Yungas

Treehoppers (Membracidae) exhibit different levels of sociality, from solitary to presocial. Although they are one of the best biological systems to study the evolution of maternal care in insects, information on the biology of species in this group is scarce. This work describes the biology and ecology of Alchisme grossa (Fairmaire) (Hemiptera: Membracidae) in a rain cloud forest of Bolivia. This subsocial membracid utilizes two host-plant species, Brugmansia suaveolens (Humb. & Bonpl. ex Wild) Bercht. & J.Presl and Solanum ursinum (Rusby) (both Solanaceae), the first one being used during the whole year and the second one almost exclusively during the wet season. The development of A. grossa from egg to adult occurred on the plant where eggs were laid. Maternal care was observed during the complete nymphal development, and involved behavioral traits such as food facilitation and antidepredatory defense. Life cycle was longer on B. suaveolens during the dry season and shorter on S. ursinum during the wet season. Mortality was similar on both host plants during the wet season but was lower on B. suaveolens during the dry season. The presence of a secondary female companion to the egg-guarding female individual and occasional iteropary is also reported.

Zootaxa

The Membracidae are a relatively diverse group with nearly 400 genera and 3200 species. For Colombia 93 genera and 394 species were previously known. Study of the literature and 3744 specimens deposited in ten colections in Colombia, as well as non-systematic collections and field observations done in Colombia between 2011 and 2014, led us to record 116 genera and 474 species grouped in 9 subfamilies and 23 tribes, distributed in 24 departments. Thirteen genera were new country records. In addition, 1449 records of host plants and 262 records of associated Hymenoptera were obtained from literature, the examined collections and new, non-systematic field trips. For each genus a differential diagnosis is presented, as well as notes on biology, distribution and some taxonomic comments. Illustrated keys for the genera of Colombian Membracidae and known distributional maps are given. After examination of several Anobilia species, we propose the new combinations Stilbophora flava (Tode, 1966) n. comb., Stilbophora luteimaculata (Funkhouser, 1914) n. comb., Stilbophora sagitatta (Tode, 1966) n. comb., Stilbophora silvana (Tode, 1966) n. comb., Stilbophora tripartita (Fairmaire, 1846) n. comb., and Stilbophora variabilis (Tode, 1966) n. comb. The male of Sakakibarella sinuosa Creão-Duarte is described.
