Key to the genera of the Neotropical Batrachideinae View in CoL

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 View in CoL ( Fig. 26 View FIGURE 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 View in CoL ( Fig. 10 View FIGURE 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 View in CoL ( Figs. 12–17 View FIGURE 12 View FIGURE 13 View FIGURE 14 View FIGURE 15 View FIGURE 16 View FIGURE 17 )

4’. Infrascapular area of pronotum prominent and tegmina present and easily visible................................... 5

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..............................................................
