Genus Neomohunia Chen & Li, 2007

Type species.

Mohunia pyramida Li & Chen, 1999, by original designation.

Diagnosis.

The genus is separated from other similar genera of Mukariini by crown rounded to face, without apical transverse marginal carina; frontoclypeus strongly convex dorsally, depressed ventro-medially; male pygofer with one or two processes at caudal apex; subgenital plate with numerous macrosetae laterally; aedeagus with pair of spinous processes arising from base, with or without a single ventral basal medial process.

Description.

Medium-sized, delicate leafhoppers; with orange, brown and reddish orange markings dorsally including reddish medial longitudinal stripe on head and pronotum.

Head and thorax. Head moderately produced, apex in profile truncate (Figs 4, 17, 29). Crown slightly convex and rounded to face, without anterior marginal carina, median length subequal to width between eyes (Figs 3-4, 16-17, 28-29); coronal suture short; ocelli near crown margin, equidistant from eyes to crown apex (Figs 4, 17, 29). Face with frontoclypeus strongly convex basally, depressed apico-medially, without median carina; clypellus with lateral margins parallel; lorum broad (Figs 5, 18, 30). Pronotum broad, wider than head including eyes, with lateral margins divergent posteriorly, anterior margin strongly convex between eyes, posterior margin weakly concave (Figs 1, 3, 14, 16, 26, 28). Mesoscutum and scutellum together wider than long, transverse suture slightly curved and depressed, not reaching lateral margin (Figs 3, 16, 28). Forewing elongate, considerably longer than abdomen, with four apical cells, venation obscure except near apex, vein M3+4 originating from inner anteapical cell, converging toward middle of appendix; appendix well developed (Figs 1-2, 14-15, 26-27). Hind wing with four closed apical cells. Profemur with AM1 and AV1 present, intercalary row with 10 or more slender setae. Protibia with macrosetal formula 7+1 and approximately 14 macrosetae of equal length in row AV (Figure 23). Hind femur macrosetal formula 2+2+1.

Male genitalia. Male pygofer broad at base in lateral aspect, tapering caudally with one or two processes at caudal apex; with macrosetae ventrocaudally (Figs 8-9, 21-22, 33-34). Valve triangular (Figs 10, 20, 32). Subgenital plate nearly triangular, with numerous macrosetae laterally (Figs 10, 20, 32). Connective Y-shaped, with stem longer than arms, apex broad (Figs 11, 24, 35). Aedeagus with pair of spinous processes arising either dorsobasally on shaft or from preatrium, with or without a single ventral basal medial process; gonopore apical or subapical on dorsal surface (Figs 11-13, 24-25, 35-36). Style with articulating arm moderately long and robust, apophysis digitate, slightly laterally curved (Figs 6, 19, 31).

Female genitalia. Sternite VII (Figs 37, 40, 43) with posterior margin strongly or slightly convex, with or without acute median tooth. First valvula (Figs 38, 41, 44) weakly curved, tapering apically with strigate sculpture extended to dorsal margin. Second valvula (Figs 39, 42, 45) broad, widest at distal two thirds, thereafter gradually tapered to acute apex; dorsal margin with numerous triangular, distinct and regular teeth; with dorsal sclerotized and hyaline region and dorsal prominence (in N. sinuatipenis ).
