Fujianella paradoxa sp. nov.

( Figs 1 View FIGURE 1 , 2 View FIGURE 2 )

Type material. Holotype, NIGP206134 View Materials (with part and counterpart), nearly complete forewing missing upper distal section. Type locality and horizon. Near Jishan Village , Yong’an City, Fujian Province, SE China; Early Cretaceous (Aptian–Albian) .

Etymology. The specific epithet is named after the term ‘paradox’, due to the combination of inconsistent forewing features from both Protopsyllioidea and Psylloidea; gender feminine.

Diagnosis. As for genus.

Description. Forewing elongate, about 5.90 mm long, reaching maximum width at 2/3 of wing length, about 2.31 mm wide at maximum width, ratio length/width = 2.55. Common stem R+M+CuA forking near wing base, at 1.19 mm from wing base (at 20% of total wing length). Common stem R short, about 0.95 mm long; fork RA and RP at 2.14 mm from wing base, before wing mid-length (around 36% of total wing length); RA forked sightly before wing mid-length, at 2.81 mm from wing base, fork at 45° angle; RA 1 very faint and straight, RA 2 curved. Common stem M+CuA long, 1.17 mm long, forked shortly after common stem R at 2.33 mm from wing base (around 40% of total wing length). Vein M forked at 3.71 mm from wing base; common stem M shorter than fork M 1 +M 2; M 1 and M 2 weakly sinusoidal, slightly diverging distally. Vein CuA forked at 2.90 mm from wing base, at wing mid-length; common stem CuA slightly shorter (almost equal) to branch CuA 2 in length; CuA 1 curved, CuA 2 straight and slightly under half length of CuA 1, resulting in wide and short AP cell; crossvein cua-cup absent. Vein CuP thinner than other veins, straight. PCu close and parallel to CuP; A present, running alongside wing margin for most its length, possibly joining PCu distally.

Remarks. The distal section of A is weakly pronounced and very thin, but based on our observations, seems to join with PCu to form a long Y shape, a character very frequent in the Auchenorrhyncha but rarely encountered in the Sternorrhyncha .
