Type species.

Multinervis guangxiensis Li & Li, 2013 .

Diagnosis.

The genus is recognised by a combination of characters including, a robust body; coloration generally brown; forewing, somewhat coriaceous, brown with contrasting pale yellow veins; crown very narrowly visible in dorsal view; face with striations along upper margin, dorsad of ocelli; ocelli in slight depressions, almost equidistant from each other as to compound eyes; granulose texture of head, pronotum, mesonotum and forewings; pronotum only weakly pitted, in lateral view slightly convex, anterior margin may be depressed, concave in lateral view; forewing bearing numerous accessory crossveins (veins appearing reticulated), with or without crossveins in claval region (between anal veins); forefemur with pale yellow and black / dark brown bands; hindfemur with macrosetal formula 2 + 1; hindtibia with 7 macrosetae on AD margin. In male genitalia structures, the subgenital plates are fused at base; in lateral view, style apophyses are distinctly spiralled. Connective elongate, broader anteriorly than posteriorly (longer than broad), in ventral view, approximately racquet-shaped.

Differential diagnosis.

According to Li and Li (2013), Multinervis is most similar to three other genera of Agalliini – Dryodurgades Zachvatkin, 1946 , Paulagallia Viraktamath, 2011 and Sangeeta Viraktamath, 2011 . However, Multinervis differs from Dryodurgades in having a shorter aedeagal shaft without apical and subapical processes, an elongate connective, longer than wide and subgenital plates fused together in basal portion (in Dryodurgades , the aedeagal shaft is longer with branched apical and often subapical processes, the connective is broader than long and the subgenital plates are not fused basally). Multinervis differs from Paulagallia in having pronotum only weakly pitted, pygofer dorsal margin not deeply excavated, only slightly concave, without short stout setae apically, subgenital plates with no macrosetae, aedeagus without lateral ridges or apical processes, and with dorsal apodeme about half as long as aedeagal shaft, and connective elongate (in Paulagallia , the pronotum is coarsely pitted, the male pygofer has a deep, angular dorsal marginal excavation around midlength, apex of pygofer bears short stout setae, subgenital plates bear macrosetae, the aedeagal shaft may have lateral ridges and small tooth-like processes apically, the aedeagal dorsal apodeme is almost as long as the shaft and the connective is about as long as wide). Based on Viraktamath (2011), a further characteristic by which Multinervis can be distinguished from the two above-mentioned genera includes the ocelli being approximately equally distant from each other as they are to the compound eyes (in Dryodurgades and Paulagallia the ocelli are closer to compound eyes than to each other). Li and Li (2013) considered another genus, Sangeeta Viraktamath, 2011 , to be close to Multinervis based on the striations of the face, but the latter differs in that it has multiple accessory forewing crossveins (while Sangeeta does not have additional crossveins). In Multinervis the face width across the eyes is greater than the face length (in Sangeeta the face is longer than wide), the number of AD macrosetae on the hindtibia is 7 ( Sangeeta has 6 ± 1 macrosetae), the dorsal margin of the pygofer is slightly concave (while in Sangeeta the pygofer has a distinct almost right-angled excavation) and the pygofer apex and subgenital plates are without macrosetae (in Sangeeta the pygofer apex has some stout setae and subgenital plates have a row of macrosetae).
