“…Sinotriadophlebia lini is the second largest Mesozoic odonatopteran from China, being slightly smaller than the damsel-dragonfly Hsiufua chaoi (107.6 mm wing for forewing length) from the Middle-Upper Jurassic of Inner Mongolia 12 . In addition, the Triassic Iverya averyi Béthoux & Beattie, 2010 is currently considered within Triadotypidae, showing combined characters of Triadotypidae and Triadophlebiomorpha.…”

The clade Triadophlebiomorpha represents a morphological ‘link’ between the Paleozoic griffenflies (Meganisoptera) and the modern taxa. Nevertheless they are relatively poorly known in the body structures and paleobiogeography. The Triassic dragonfly is extremely rare in China with only one previously recorded. A new family, Sinotriadophlebiidae Zheng, Nel et Zhang fam. nov., for the genus and species Sinotriadophlebia lini Zheng, Nel et Zhang gen. et sp. nov., is described from the Upper Triassic Baijiantan Formation of Xinjiang, northwestern China. It is the second Chinese Triassic odonatopteran and the second largest Mesozoic representative of this superorder in China. The discovery provides new information for the clade Triadophlebiomorpha during the Late Triassic and expands its distribution and diversity in Asia. The find reflects a close relationship between the two Triassic entomofaunas from Kyrgyzstan and the Junggar Basin, and provides a Carnian age constraint on the lowermost part of the Baijiantan Formation.

“…Five orders, Odonata (dragonflies and damselflies), Blattaria (cockroaches), Orthoptera (grasshoppers and katydids), Plecoptera (stoneflies), and Mecoptera (scorpionflies), have moderately high numbers of described species (Figure 1). A member of an extinct group of Odonata, Hsiufua chaoi, from the Yanliao Entomofauna was considered to be the largest known fossil dragonfly in China; it has a forewing length of 107.6 mm (98). Some clades of living cockroaches, such as the oldest-known representative of Blattidae, have been reported from the Jehol Entomofauna (19).…”

During the past 20 years, more than 1,600 species of well-preserved fossil insects, including members of over 270 families within 24 orders, have been described from the Middle Jurassic Yanliao Entomofauna and Early Cretaceous Jehol Entomofauna in Northeastern China. Diversified fossil insects not only document the origin, systematics, and early evolution of many lineages, but also reveal these lineages’ behaviors and interactions with coexisting plants, vertebrates, and other insects in their ecosystems. For example, fossil evidence has been documented, for example, regarding insects’ feeding and pollination mutualism with gymnosperms; ectoparasitic feeding on blood of vertebrates; camouflage, mimicry of gymnosperm plants, and eyespot warning; sound stridulation for attracting potential mates; and sexual display, mating, egg-laying, and parental care. In this article, we review the diverse taxonomy of mid-Mesozoic insects of Northeastern China and elucidate their behaviors and interactions within their ecosystems, which have impacted their early evolution and development into extant insects. Expected final online publication date for the Annual Review of Entomology, Volume 66 is January 11, 2020. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates.

“…Curiously, however, the basal part of the abdomen is narrow and constricted (width reducing to ˜2 mm) suggesting possible distortion, but

˜12 mm (comparable with Petalura ingentissima ) and this estimated value is used in Table . Another large, well‐preserved specimen is the isoplebiopteran species Bellabrunetia catherinae (Fleck & Nel, ), reassigned to the Haifanggou Formation (Middle Jurassic) by Zhang et al .

Heavily loaded flight and limits to the maximum size of dragonflies (Anisoptera) and griffenflies (Meganisoptera)

An original hypothesis is presented that the maximum mass and size of living anisopteran dragonflies are constrained by a physiological performance limit: the wing muscle power required to permit reproductively successful males to carry heavier females in the so‐called ‘wheel position’ in flight. It is proposed that the same limit cannot have applied to all fossil Odonatoptera. As the physiology of the giant Carboniferous griffenfly Namurotypus sippeli precludes flight in the wheel position, it did not need to carry any substantial load aside from exogenous aerial prey. Based on its thorax dimensions, it is argued that Namurotypus flew with a relatively low maximum specific muscle power output in comparison with living Anisoptera. The extinction of some families of large Mesozoic Odonatoptera may have been exacerbated by competition with smaller (stem‐) Anisoptera that evolved higher specific power outputs and superior flight performance similar to living Anisoptera. To investigate the credibility of this flight‐performance size‐limit hypothesis and its consequences, an analysis of the scaling of the required flight power and available muscle power is presented using allometric relations. It is found that for living Anisoptera and fossil Odonatoptera, there are different limiting sizes, above which the required specific flight power would exceed the available muscle specific power. These limits are directly related to maximum load‐carrying capacity and the atmospheric air density at the habitual altitude. It is suggested that the largest living species of Petaluridae, Petalura ingentissima, is close to the proposed Anisoptera size limit at current near‐sea‐level air density conditions.
