Key to the genera of the tribe Zammarini

Below, the first key to both males and females for all (described) species within the Tribe Zammarini is provided.

There are several genera ( Plautilla Stål 1865 , Procollina Metcalf 1963 , Daza Distant 1905 , Aragualna Champagnet, Boulard & Gaiani 2000 , Onoralna Boulard 1996 ) that are at present placed outside of Zammarini , which may prove to be members of the tribe. Currently molecular data and additional morphological data are being collected for each to help determine their taxonomic position within the Cicadidae .

1. Median (M) and anterior cubital (CuA) vein arising together from the basal cell ( Figs 2 left, 4, 5); 2 or 3 tarsomeres, first tarsomere sometimes strongly reduced ( Fig. 3 ).......................................................................................... 2

– Median (M) and anterior cubital (CuA) vein arising separately from the basal cell, separated by a distance of at least the width of either vein ( Fig. 2 right); 3 tarsomeres, first tarsomere sometimes strongly reduced ( Fig. 3 right) ..... 4

2. Two tarsomeres, first tarsomere sometimes only visible in ventral view ( Fig. 3 left)............................................................................. Zammara

– Three tarsomeres, first tarsomere sometimes only visible in ventral view ( Fig 3 right) ......................................................................................................... 3

3. M and CuA juxtaposed ( Figs 2 left, 5); apical 1/3 to 1/2 of fore wing infuscated with wavy pattern of brown and grayish, basal half transparent........... ............................................................................................... Zammaralna

– M and CuA juxtaposed or fused (at least at base, Figs 2 left, 4 & 5); fore wing transparent with scattered infuscations or apical part infuscated but not with wavy pattern .................................................................................. Orellana

4. Both fore and hind wings at least partly infuscated, hind wing sometimes only very small part of apical cells directly bordering apical margin............ 5

– At least hind wing completely transparent, i.e., no infuscation present (except for vannal fold, jugum and apical wing margin in some species) ( Fig. 4 ) .... 8

5. Hind wing completely infuscated; fore wing completely opaque. (Restricted to Cuba) ........................................................................................ Juanaria

– Hind wing not completely infuscated; at least some areas of fore wing transparent ........................................................................................................ 6

6. Infuscations of fore wing restricted to apical 1/3rd, infuscations following veins of apical cells; infuscations of hind wing restricted to apical 1/4th (and vannal fold)...................................................................... Odopoea (in part)

– Infuscations present over whole length of fore wing, infuscations less restricted to wing veins; infuscations of hind wing at least present in apical wing margin and part of apical cells directly bordering apical margin ................. 7

7. Infuscations of hind wing only present in apical wing margin and part of apical cells directly bordering apical margin (and vannal fold). (Restricted to Mesoamerica)................................................................................. Miranha

– Infuscations of hind wing present both at apical wing margin (and vannal fold), and at central internal edges of basal cells. (Restricted to Mexico and Dominican Republic) .................................................................... Chinaria

8. Width of pronotal flange ( Fig. 5 ) less than half diameter of eye (restricted to Cuba, Haiti and Dom. Rep.) ...................................................... Uhleroides

– Width of pronotal flange ( Fig. 5 ) at least half diameter of eye .................... 9

9. Veins of fore wing evenly striped; width of pronotum (at widest point, including flanges) more than 1.7 times width of head including eyes. (Restricted to Puerto Rico)....................................................................... Borencona

– Veins of fore wing evenly colored, not striped; width of pronotum (at widest point, including flanges) less than 1.5 times width of head including eyes.... ........................................................................................ Odopoea (in part)
