Key to Colombian genera of Hypselonotini

This tribe is considered by some authors as a junior synonym of Coreini , therefore the main keys for the determination of its genera use this name. The most complete keys to genera includes ones being a key to the genera of North America ( Fracker 1923), Florida ( Baranowski & Slater 1986) , and the genera related to Althos Kirkaldy ( Brailovsky 1990d) . So far, there are no keys that cover the tribe as a whole or the neotropical genera. Therefore, we provide a key to the Colombian genera:

1 Antennal segment III globose; humeral angles conspicuously developed into a horn, projected forward, making the pronotum resemble a half-moon........................................................................ Bulbocornis

- Antennal segment III terete or flattened, but never globose; humeral angles variables............................... 2

2 Body dorsally and/or ventrally with metallic iridescence...................................................... 3

- Body without metallic iridescence....................................................................... 6

3 Antennal segment II shorter than III...................................................................... 4

- Antennal segment II longer than III...................................................................... 5

4 Dorsal coloration almost entirely with metallic iridescence except on the scutellum....................... Stenoprasia

- Dorsal coloration variable, but always with the hemielitra entirely dull or if with metallic iridescence, then claval commissure and inner border of corium yellowish white......................................................... Sundarus

5 Antennal segments II-III iridescent and cylindrical; pronotal calli, tibiae and abdominal sternites V-VI metallic; triangular processes of pronotum absent.................................................................... Paryphes

- Antennal segments II and III dull, flattened and furrowed; pronotal calli, tibiae and abdominal sternites V-VI dull; triangular processes of pronotum present.................................................................. Sphictyrtus

6 Humeral angles projected into a long thin spine............................................................. 7

- Humeral angles variable but never spined.................................................................. 8

7 Hind femora thickened and ventrally armed with long spines.............................................. Zicca

- Hind femora not thickened and ventrally with small inconspicuous denticles.............................. Daphnasa

8 Antennal segments II-III dorsoventrally flattened and sulcate towards the midline........................... Sethenira

- Antennal segments II-III terete........................................................................... 9

9 Anterolateral borders of the pronotum conspicuously tuberculated..................................... Acidomeria

- Anterolateral borders of pronotum smooth or softly crenulated................................................ 10

10 Femora, at least the posterior, armed with one or more long spines............................................. 11

- All femora unarmed or at most with a row of small tubercles................................................. 14

11 Head small, about one-third the width of the pronotum............................................ Anasa (In part)

- Head larger, about half the width of pronotum............................................................. 12

12 Femora with only one or two apical spines................................................ Hypselonotus (In part)

- Femora with two rows of spines, highly developed on hind legs and not very conspicuous on middle and anterior legs.... 13

13 Hind tibiae armed with two rows of spines.......................................................... Namacus

- Hind tibiae unarmed, only with short, downward directed bristles........................................ Nirovecus

14 Tylus conspicuously elevated and compressed between jugum................................................ 15

- Tylus not elevated above jugum........................................................................ 16

15 Female genital plates elongated and laminar; distal lobe of parameres elongated.............................. Althos

- Female genital plates short or medium; distal lobe of parameres short............................... Vazquezitocoris

16 Antennal articulation covered by a genal plate..................................................... Catorhintha

- Antennal articulation not covered by a plate............................................................... 17

17 Rostrum short, barely exceeding procoxae................................................................ 18

- Rostrum longer, reaching, or surpassing mesocoxae......................................................... 19

18 Humeral angles expanded triangularly to the sides and slightly forward; antenniferous tubercles unarmed...... Sundarellus

- Humeral angles slightly expanded; antenniferous tubercles armed with a small dorsal spine.................... Cimolus

19 Antennae short, first segment shorter than head length; pronotum orange with four longitudinal black lines; pleura orange with several series of subcircular dots................................................................. Microbasis

- Other combination of characters........................................................................ 20

20 Frontal angles of pronotum projecting into a blunt tooth almost touching the postocular tubercles; antennal tubercle never armed; coloration predominantly chestnut and pale yellow................................................... 21

- Frontal angles of pronotum not projecting into a blunt tooth; antennal tubercle armed or unarmed; coloration variable.... 22

21 Female abdominal sternite VII mesially grooved and flattened laterally................................... Cebrenis
