Olidiana fletcheri sp.nov.

Figs. 2 D , 5 D , 8 C , 30 A–H.

Male. Ohraceous brown, face uniformly pale brown; compound eyes dark brown. Forewing brown with numerous small ochraceous specks. Hind femur with apices, tibia and tarsal segments brown, setae on hind tibia pale yellow ( Figs. 2 D , 5 D , 8 C ).

Male genitalia. Pygofer longer than wide, without caudoventral or caudodorsal processes ( Fig. 30 H ). Subgenital plate long, broad basally, slightly narrowed apically, with small hair-like setae on lateral margin, also apically ( Fig. 30 E ). Style short, broad basally and slightly tapered apically, apophysis of style uniform in width and not narrowed distally ( Fig. 30 F ). Connective Y-shaped, wider basally than long ( Fig. 30 G ). Aedeagus tubular with long lateral subapical process reaching half length of shaft, process of aedeagus curved with spicules restricted to distal 1/5, gonopore arising at base of the process and opening laterally ( Figs. 30 A–D).

Measurements. Male 6.3−6.4 mm long, 1.6 mm wide across eyes and 2.0 mm wide across posterolateral angles of pronotum.

Material Examined. HOLOTYPE ♂, INDIA: Meghalaya: Pomlum , 2.vi.2012, Net sweeping, N. M. Meshram ( NPC) ; PARATYPE 1 ♂, Barapani, 24.ix.2013, Yeshwanth, H.M. ( UASB) .

Etymology. This species is named after Dr. Murray J. Fletcher ( Australia) in recognition of his contributions to the leafhopper taxonomy.

Remarks. O. flectheri sp. nov. resembles O. fasciculata (Nielson) but differs in the following characters: 1. Style with apophysis of uniform width and not narrowed distally ( Fig. 30 F ); 2. Aedeagus with subapical process curved and with spicules restricted to distal 1/5 ( Figs. 30 A–D) compared to sinuate rpcoess with spicules on more than ½ distal length. It also resembles O. knowltoni (Nielson) from Malaysia (Sabah and Sarwak) in having slightly broadened apex of shaft but differes in having slightly curved subapical process compared to strongly sinuate subapical process in the latter.
