Moderate to good-sized species; mesonotal suture (MNs) in anterior part of mesonotum strongly stretched backwards medially, not transverse; paired medioparapsidal sutures (MPs) anastomosed at middle area of mesonotum, not parallel; lateroparapsidal suture (LPs) curved laterally; metanotum relatively long. Forewing about 2.4 times as long as its width; membrane thickened at distal part of the field between C and RA; RS forking about 10mm from base of forewing, RSa formed two triads, RSp nonbranched; distinct intercalary veins existing between MP2 and CuA1; CuA1 with 4–6 triads (loop-shaped veinlets) leading to wing margin; numerous crossveins and intercalary veins between longitudinal veins.

The later two features of wing venation are present in Late Jurassic genus <i>Hexagenites</i> Scudder, 1880 and Lower Cretaceous genus <i>Cratogenites</i> Martins-Neto, 1996, but in contrast to them, hind wing of <i>Epicharmeropsis</i> is more or less than half as long as forewing.</p> <p> <b>Remark.</b> The combined characters of this new genus allow an allocation of it to the family Hexagenitidae: moderate to large size; vein CuA of forewing forked, one of its branches with a series of triads (loopshaped veinlets) leading to wing margin.</p> <p> <i>Epicharmeropsis</i> <b>gen. nov.</b> possesses a peculiar combination of characters: mesonotal suture (MNs) in anterior part of mesonotum strongly stretched backwards medially, not transverse; paired medioparapsidal sutures (MPs) jointed at middle area of mesonotum, not parallel; forewing less than 2.5 times as long as its width; RSp non-branched; the presence of intercalary veins between MP2 and CuA1; hindwing broad, about 1.6 time as long as its width, with fairly obtuse tip. These characters allow formal separation of this new genus from other known genera of the Hexagenitidae established by mayfly adults, extant or in fossil records.</p>Published as part of <i>Huang, Jiandong, Ren, Dong & Shih, Chungkun, 2007, New genus and species of Hexagenitidae (Insecta: Ephemeroptera) from Yixian Formation, China, pp. 39-50 in Zootaxa 1629</i> on page 40, DOI: <a href="http://zenodo.org/record/179369">10.5281/zenodo.179369</a>

Chao Yuen Ren (1892–1982)
No full textY. R. Chao is easily the most famous linguist to have come out of China. Born before the end of the last dynasty in China, he received a traditional Confucian education, but was also one of the first Chinese people to be sent to the West for training in modern Western science (under the Boxer Indemnity Fund). The remarkable breadth and scope of his studies included physics, mathematics, linguistics, musical and literary composition, and translation, and he was a pioneer in many of these fields

Parabrunetia Zhang, Fleck, Huang, Nel, Ren, Cheng & Lin, 2006, n. gen.
No full textGenus Parabrunetia n. gen. Huang, Fleck, Nel & Lin Diagnosis. This genus is very similar to Pternopteron, Bellabrunetia, and Amnifleckia. In particular, they share the strongly reduced veins CuAa in fore and hind wing. It differs from Pternopteron in its Ax 1 distinctly basal of arculus. It differs from Bellabrunetia and Amnifleckia as follows: presence of a dense net of irregular cells in anal area of hind wing; hind wing subdiscoidal space crossed by two veins; postdiscoidal area of fore- and hind wing strongly broadened near posterior wing margin; fore wing subdiscoidal space distinctly narrower. Type species. Parabrunetia celinea n. sp. Etymology. After Para and Bellabrunetia because of its strong similarities with this last genus.Published as part of Zhang, Bing-Lan, Fleck, Gunther, Huang, Di-Ying, Nel, André, Ren, Dong, Cheng, Xiao-Dong & Lin, Qi-Bin, 2006, New isophlebioid dragonflies (Odonata: Isophlebioptera: Campterophlebiidae) from the Middle Jurassic of China, pp. 51-68 in Zootaxa 1339 on page 63, DOI: 10.5281/zenodo.17436
