Nymphites

Shi, Chaofan, Makarkin, Vladimir N., Yang, Qiang, Archibald, S. Bruce & Ren, Dong, 2013, New species of Nymphites Haase (Neuroptera: Nymphidae) from the Middle Jurassic of China, with a redescription of the type species of the genus, Zootaxa 3700 (3), pp. 393-410 : 405

Nymphites sp. A

( Figs 4 B, 9, 10)

Description. Thorax, abdomen fragmentary preserved; details not visible. Meso-, metafemora long, rather swollen. Mesotibiae relatively stout, short. Metatibiae long, slender with short terminal spurs ( Fig. 4 B). All preserved segments covered with dense, relatively short hairs.

Hind wing 25.8 mm long, 10.2 mm wide as preserved. Trichosors not preserved. Costal space rather narrow. Subcostal veinlets mostly simple in proximal 2/3; once or twice shallowly forked distally. ScP, RA stout for entire length. Subcostal space moderately broad; no crossveins detected. RP smooth, not zigzagged; originating near wing base. Eleven irregularly arranged crossveins between RA, RP before fusion of ScP + RA; not detected after fusion. RP with eight preserved branches (estimated 11–12 complete). Crossveins in radial space rather rare, irregularly spaced in proximal proximally. MA, MP fragmentarily preserved, branching not preserved. Intermedial crossveins long, somewhat oblique. CuA long, pectinate branched with nine preserved long branches, some deeply forked; branches inclined to CuA at rather acute angle; all preserved branches connect by one crossveins forming gradate series. CuP fragmentarily preserved, short. Anal veins not preserved.

Material. CNU-NEU-NN2011118PC (part, counterpart), deposited in CNUB. Fragmentarily preserved body with two incomplete hind wings.

Remarks. This species is clearly not conspecific with Nymphites bimaculatus sp. nov. It differs from the latter by the more acute angle between Cu and its branches, more scarce crossveins, and probably wider hind wing. However, as this specimen is very incompletely preserved, we refrain from naming the species pending more complete specimens.
