Key to genera of the tribe Eccritotarsini of India and Sri Lanka
1. Cuneus reaching apex of hemelytral membrane (Figs 3D, 4A, 9G, I, 10). Vertex between eyes with a distinct transverse depression ........................................................................................................ 2
– Cuneus terminating well anteriad of apex of membrane. Vertex without a transverse depression, sometimes with longitudinal, median sulcus .................................................................................... 3
2. Dorsum brightly reddish orange (Figs 9G–H, 10). Larger, total length 4.9–5.4. Left wall of genital capsule with a spinelike process. Left paramere apically bifid ...... Thaumastomiris Kirkaldy, 1902
– Dorsum lemon yellow (Figs 3D–F, 4A–C). Smaller, total length 3.2–3.7. Genital capsule without spinelike processes. Left paramere gradually tapering apically (Figs 21E, 22B) ............................... .......................................................................................................................... Namyatovia gen. nov.
3. Vertex distinctly carinate posteriorly. Pronotal collar narrow, posteriorly delimited with a deep suture. Costal margin of hemelytron basally serrated (Fig. 1) ...................... Dioclerus Distant, 1910
– Vertex not carinate. Pronotal collar posteriorly delimited with a shallow sulcus. Costal margin of hemelytron smooth ........................................................................................................................... 4
4. Dorsum uniformly pale yellow. Body elongate, gracile, with long appendages. Eyes distinctly separated from anterior margin of pronotum (Figs 4D–F, 9A, C, E, 27C–D) .................................. 5
– Dorsum with variable color-pattern or uniformly dark brown, but never uniformly pale yellow. Body more robust, broadly oval to elongate-oval. Eyes in contact with or slightly separated from pronotum ........................................................................................................................................... 6
5. Eyes large, distinctly stylate. Vertex with a shallow longitudinal sulcus along midline. Antennal segment I bottle shaped, with a narrowed basal one-fourth (Fig. 9A–E) ........................................... .................................................................................................................... Prodromus Distant, 1904
– Eyes small, not stylate. Vertex without a sulcus. Antennal segment I uniformly slender, narrowed only at extreme base (Fig. 4D–F) .................................................................... Stonedahlia gen. nov.
6. Calli anteromedially delimited with impressed line forming characteristic subtriangular region between collar and calli .................................................................................................................... 7
– Anterior part of pronotum without clearly delimited subtriangular region between collar and calli. ........................................................................................................................................................... 8
7. Dorsum pale brown to reddish yellow, with dark longitudinal interrupted stripes. Pronotal collar at least twice as wide as antennal segment II (Fig. 6D–I) .............................. Lopidolon Poppius, 1911
– Dorsum bicolored; reddish anteriorly, bluish black to black posteriorly. Pronotal collar as wide as or narrower than diameter of antennal segment II (Figs 3A–B, 8A, D, G) .......... Mertila Distant, 1904
8. Coloration of dorsum uniform, dirty yellow to black, sometimes with paler embolium. Calli dorsally and laterally separated by deep impressed lines giving appearance of three distinct sections of pronotum (Figs 2C–D, 5J, L) ..................................................................... Harpedona Distant, 1904
– Coloration of dorsum contrasting, with clavus, transverse spot in medioapical part of corium, apex of cuneus, and cells uniformly brown to dark brown; remaining part of hemelytron and legs whitishyellow. Calli distinct, but not separated by impressed lines (Figs 2A–B, 6A–B, 26B–C, F) ........... 9
9. Pronotum uniformly black and coarsely punctured. Hemelytra with slightly convex costal margin (Fig. 2A–B) ................................................................................................. Ernestinus Distant, 1911
– Pronotum behind calli with narrow, impunctate whitish carina along midline. Hemelytra slightly constricted on basal fourth, with concave costal margin (Fig. 6A) ...... Jessopocoris Carvalho, 1981
