Elimaea (Elimaea) thaii Ingrisch, 1998

( Figs. 11–19 )

Material examined (2 Specimens). Meghalaya: East Khasi Hills, 6.vi.2013 R. Swaminathan; 7.vi.2013 Rajendra Nagar (Umiam).

Description. Fastigium verticis narrow, dorsally furrowed, apex sub-acute; pronotum with disc flattened in posterior area ( Fig.11 ), lateral angles rounded ( Fig.12 ); transverse sulcus short Y- shaped ( Fig.11 ), slightly behind middle; paranota about 1.1–1.2x longer than high; ventral and posterior margins rounded together; humeral sinus distinct; tegmina surpassing hind knee; radius sector branching between 7.5–12 mm from the base.

Male. Stridulatory file with ca. 34–42 teeth which are large and somewhat spaced from each other in basal half and gradually becoming narrower and denser towards apex ( Fig.15 );tenth abdominal tergite with apical margin broadly rounded; central area setose and with a distinct puncture in middle; epiproct long tongue shaped; cerci short and strongly curved; apical area short, compressed, and twisted, slightly curved with apex acute ( Fig.14 );subgenital plate narrow, split for slightly less than apical half ( Fig.13 ).

Female. Tenth abdominal tergite with apex sub-truncate or slightly concave with a distinct puncture in middle; epiproct long, triangular, apex sub-obtuse; cerci moderately curved, slender, apex varying from sub-acute to obtuse ( Fig.16 );sub-genital plate long, triangular, in general outline with a medial furrow bordered by a carina at each side; apex, sub-truncate between two slightly projecting lateral angles ( Fig.17 ); gonangulum ( Fig.18 ) of ovipositor ( Fig.19 ) with ventro-apical appendage smaller than in E. subcarinata and E. chloris .

Elimaea (Elimaea) subcarinata (Stål, 1861) ( Figs. 29–36 )

Material examined (3 Specimens). Meghalaya: East Khasi Hills, 6.vi.2013 R. Swaminathan (NEH, Umiam); 6.vi.2013 Jhabar Mal (Dawki), 2.vi.2013 Rajendra Nagar (Mawflang).

Description. Fastigium verticis narrow, apex sub-acute, dorsal surface furrowed. Pronotum with disc flattened, especially in posterior area, lateral angles rounded; transverse sulcus Y- shaped, slightly behind middle ( Fig.29 ); anterior margin concave, posterior margin rounded; paranota longer than high, ventral and posterior margins rounded; humeral sinus distinct. Tegmina surpassing hind knee; radius sector branching ca. 8–10 mm from base. Anterior femur with spines on the both ventral margin. Meso and post femora with spines on ventro-external margin. Genicular lobes bispinose. Anterior tibia with external and internal, dorsal and ventral apical spurs.

Male. Stridulatory file with 6–9 large to medium sized teeth and a few indistinct minute teeth ( Fig.32 );tenth abdominal tergite with apex broadly rounded; central area setose and with a small puncture in middle; epiproct tongue shaped, apex obtuse; cerci strongly curved, apical area compressed, sinuate and external side convex, internal concave, with narrowing margins and apex sub-acute on dorsal carinal side ( Fig.30 ); sub-genital plate moderately curved dorsad, split into two obtuse lobes in ca. apical third ( Fig.31 ).

Female. Cerci weakly to regularly curved with apex narrowed, sub-obtuse ( Fig.34 ); sub-genital plate excised and bifid with triangular apices; gonangulum of ovipositor bulbous ( Fig.35 ), a little larger than the other E. subcarinata stat. rev., lies in a cleft between dorsal and ventral valves of ovipositor ( Fig.36 ).
