Tribe Eccritotarsini Berg, 1883

Diagnosis

Recognized among Miridae by the presence of large, circular pulvilli broadly attached to the inner surface of the claw. Refer to Konstantinov et al. (2018) for detailed discussion of distinctive features.

Key to genera of the tribe Eccritotarsini of India and Sri Lanka

1. Cuneus reaching apex of hemelytral membrane ( Figs 3D View Fig , 4A View Fig , 9G, I View Fig , 10 View Fig ). 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 View Fig , 10 View Fig ). Larger, total length 4.9–5.4. Left wall of genital capsule with a spinelike process. Left paramere apically bifid ...... Thaumastomiris Kirkaldy, 1902 View in CoL

– Dorsum lemon yellow ( Figs 3D–F View Fig , 4A–C View Fig ). Smaller, total length 3.2–3.7. Genital capsule without spinelike processes. Left paramere gradually tapering apically ( Figs 21E View Fig , 22B View Fig ) ............................... .......................................................................................................................... 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 View Fig ) ...................... Dioclerus Distant, 1910 View in CoL

– 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 View Fig , 9A, C, E View Fig , 27C–D View Fig ) .................................. 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 View Fig ) ........................................... .................................................................................................................... Prodromus Distant, 1904 View in CoL

– Eyes small, not stylate. Vertex without a sulcus. Antennal segment I uniformly slender, narrowed only at extreme base ( Fig. 4D–F View Fig ) .................................................................... 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 View Fig ) .............................. Lopidolon Poppius, 1911 View in CoL

– 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 View Fig , 8A, D, G View Fig ) .......... Mertila Distant, 1904 View in CoL

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 View Fig , 5J, L View Fig ) ..................................................................... Harpedona Distant, 1904 View in CoL

– 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 View Fig , 6A–B View Fig , 26B–C, F View Fig ) ........... 9

9. Pronotum uniformly black and coarsely punctured. Hemelytra with slightly convex costal margin ( Fig. 2A–B View Fig ) ................................................................................................. Ernestinus Distant, 1911 View in CoL

– Pronotum behind calli with narrow, impunctate whitish carina along midline. Hemelytra slightly constricted on basal fourth, with concave costal margin ( Fig. 6A View Fig ) ...... Jessopocoris Carvalho, 1981 View in CoL
