Arcofuzia cana gen. et sp. n. (Insecta, Blattaria, Fuziidae) from the Middle Jurassic sediments of Inner Mongolia, China Author Wei, Dandan Author Shih, Chungkun Author Ren, Dong text Zootaxa 2012 3597 25 32 journal article 10.5281/zenodo.283202 ede67cab-6e86-4269-9a98-f10a7df6407a 1175-5326 283202 Genus Arcofuzia Wei, Shih et Ren gen. nov. Type species: Arcofuzia cana Wei, Shih et Ren sp. nov. Differential diagnosis: Forewing extremely wide, Sc thick and without branches, with many small crossveinlike reticulations that are more distinct than in Fuzia ; wing venation rich (43 to 54 veins at margin), more than average venation in Fuzia ; intercalary veins thick, distinct all over wing surface; anal field with distinct diagonal kink; with distinctly cambered markings located near the apex of forewings from anterior of R to the anterior of CuA, forming a crescent. Etymology: Arcofuzia is a combination of arco- (Latin for cambered), referring to its cambered markings near the apex of forewings, and the type genus name ‘ Fuzia ’; gender feminine. Remarks : The new genus differs from Parvifuzia Guo & Ren, 2011 in having larger body size and rich forewing venation. The new genus can be distinguished from Fuzia Vršanský, Liang & Ren, 2009 by forewing markings, thick Sc, many small but very distinct crossvein-like reticulations, and diagonal kink in the anal field. The new genus is similar to Colorifuzia Wei, Liang & Ren (in press) in body size, rich forewing venation and forewing markings, but differs mainly by the shape of the markings, the anal field diagonal kink, presence of numerous small crossvein-like reticulations and thick, unbranched forewing Sc.
