Flatfronta dibangi sp. nov.

Figs 1-12.

FIG. (1–12) Flatfronta dibangi sp. nov. 1–2. Habitus dorsal, lateral; 3. Face; 4–5. Style dorsal, apophysis magnified (ventral); 6–8. Pygofer lateral, ventral; 9. Subgenital plate with valve; 10-12. Aedeagus dorsal with Connective, magnified apical shaft, aedeagus lateral. Yellow, crown with one reddish orange longitudinal stripe on either side of median line reaching anterior margin of pronotum and then faded, pale orange stripe extending till hind margin of pronotum (Figs. 1-2). Pronotum with four transparent longitudinally parallel faded orange bands; mesonotum with two creamy white triangles at base. Eyes black, ocelli transparent. Forewing hyaline, one dark brown spot on third apical cell.

Medium sized dorsoventrally depressed leafhoppers. Head including eyes narrower than pronotum; crown produced anteriorly, median length as long as width between eyes; ocelli on crown placed anteriorly, closer to eyes than to each other; coronal suture extending to 2/3 length of crown; frontoclypeus bulged at 1/3 rd, abruptly depressed posteriorly (Figs. 2-3); clypellus narrowed apically (Fig. 3); antennal ledges prominent; pedicel visible dorsally. Pronotum as long as wide; anterior margin convexly rounded, hind margin concave. Mesonotum wider than long.

Male genitalia: Pygofer longer than wide; macrosetae on the posterior half (Figs. 6-7); ventral process well developed not branched, reaching anterior margin of pygofer (Figs. 7-8). Valve broader than long, posterior margin obtuse. Subgenital plate about 3.5X as long as broad at base, triangular, separate from valve, uniseriate macrosetae on the lateral margin (Fig. 9). Style short without preapical lobe, hair like setae subapically, apophysis rectilinear, apex truncate and maculose (Figs. 4-5). Connective inverted V-shaped (Fig. 10). Aedeagus short and stout, about as long as connective in lateral view, slightly curved anteriorly (Fig. 12) with pair of short teeth like lateral and median projections, lateral ledges prominent with median membranous region at apex, dorsal apodeme absent, gonopore subapical on caudal margin (Figs. 10-11).

Measurements: Male 4.63mm long and 1.45mm wide across eyes.

Material examined: HOLOTYPE ♂, India: Arunachal Pradesh: Basar , 661m, 27º58’39”N 94º41’31”E, 30.vi.2018, at light, Stuti & Tahseen R. Hashmi ( NPC) . PARATYPES 2♂, same data as holotype ( NPC) .

Etymology: The species name “ dibangi ” refers to bamboo plant in local dialect.

Remarks: Flatfronta dibangi sp. nov. closely resembles F. bella (the characters of F. bella in parenthesis) but differs as follows: aedeagal shaft in lateral view short and stout, with a pair of short teeth apical process (slender and long with one pair of long fine finger-like apical process), style apophysis truncate apically and preapical lobe absent (apophysis finger-like, rounded at apex, preapical lobe present).
