description: Key to the genera of the Neotropical Batrachideinae
Definitions of genera are present in Bruner (1910), Grant (1955a, b; 1956, 1962), Rehn & Grant (1958, 1961), Cadena-Castañeda & Cardona (2015), and Cadena-Castañeda et al. (2019). Here, we present an update key with images referring to the characteristics used.
1. Body robust (compact, square shaped) or fusiform, usually brachypronotal specimens but macropronotal can be found, wings present or absent...................................................................................... 2
1’. Body not usually robust (compact, square shaped) neither fusiform, but is elongated and/or slender, only macropronotal specimens known, wings present........................................................................ 9
2. First portion of median carinae (lateral view) undulated, with a small pronounced pre-humeral ‘hump’..................................................................................................... Plectronotus (Fig. 26)
2’. First portion of median carinae (lateral view) not undulated, without a small pronounced pre-humeral ‘hump’............ 3
3. Tegminal sinus of pronotal lobes absence, pronotum surpassing the apex of the abdomen............ Cranotettix (Fig. 10)
3’. Tegminal sinus of pronotal lobes absent or very reduced, pronotum not surpassing the apex of the abdomen (brachypronotal) ................................................................................................... 4
4. Infrascapular area of pronotum prominent and tegmina lacking or cryptic.................... Halmatettix (Figs. 12–17)
4’. Infrascapular area of pronotum prominent and tegmina present and easily visible................................... 5
5. Anterior margin of the pronotum (lateral and dorsal view) not hook-like, body fusiform (drop shape)...................................................................................................... Paxilla (Figs. 24, 25)
5’. Anterior margin of the pronotum (lateral and dorsal view) hook-like, body not fusiform............................. 6
6. Frontal costa and fascial carinae (frontal view) widely divergent, forming a scutellate frontal structure (as shield-shaped)....................................................................................... Puiggaria (Fig. 27)
6 ’. Facial carinae not as above.............................................................................. 7
7. Macropronotal or brachypronotal; female hind femur usually not robust, elongated forehead and anterior edge of pronotum angulate, uncinate at tip.............................................................. Batrachidea (Figs. 2–9)
7’. Only brachypronotal; female hind femur robust, not elongated forehead and anterior edge of pronotum subquadrate at tip... ................................................................................................... 8
8. Anterior margin of the pronotum (lateral and dorsal view) hook-like; middle femur apical spine; presence of lateral darkish perpendicular band from eyes to disc pronotal region...................................... Rehnidium (Fig. 28–33)
8’. Anterior margin of the pronotum (lateral and dorsal view) hook-like or not; middle femur apical spine present or absence, lateral darkish perpendicular band from eyes to disc pronotal region also absence...................... Tettigidea part
9. Frontal costa poorly highlighted, well-marked fascial carinae, with a “V” inverted shape, anterior margin of the pronotum (lateral and dorsal view) not hook-like, hind femur slender................................ Paurotarsus (Fig. 18–23)
9’. Frontal costa visible, well-marked fascial carinae with others shape, anterior margin of the pronotum (lateral and dorsal view) hook-like, hind femur robust........................................................................... 10
10. Frontal costa (lateral view) protrusive, almost horn-like............................................. Lophoscirtus
10’. Frontal costa (lateral view) not protrusive as horn-like....................................................... 11
11. Body elongated, middle femur apical spine absent, rectangular outline of the frontal costa and fastigium facial angle (Tetrix -like’ in appearances), tegmina without spots................................................ Eutettigidea (Fig. 11)
11’. Body elongated or not, middle femur apical spine present or absence, the shape of frontal costa and fastigium not as above, tegmina usually with spots............................................................................. 12
12. Body slender and elongated, anterior margin of the pronotum (lateral and dorsal view) always hook-like, mid femur with a dorso-apical spine, presence of lateral darkish perpendicular band from eyes to disc pronotal region usually present............................................................................................... Scaria (Fig. 34)
12’. Body elongated and slightly robust (almost to the tegmina region), anterior margin of the pronotum (lateral and dorsal view) hook-like or not, mid femur dorso-apical spine usually lacking, presence of lateral darkish perpendicular band from eyes to disc pronotal region in few specimens.............................................................. Tettigidea part
