KEY TO GENERA OF NOTHOBROSCINA

1. Each side of head with a single supraorbital puncture plurisetose; external apex of foretibia expanded; elytra with row of setiferous punctures on 7th interval...2

- Each side of head with one or more supraorbital punctures, bearing a single seta; external apex of foretibia not expanded; elytra without row of setiferous punctures on 7th interval............. 4

2(1). Foretibia wide, markedly expanded at apex; middle and hind tibiae curved and greatly expanded at apex, very punctuated on the outer side....... Brullea

- Foretibia thin, with an expansion at apex, middle and hind tibiae not curved and expanded, with few punctures on outer side.......................... 3

3(2). Antennomeres 2–10 lacking pubescence except for an apical ring of setae; glossal sclerite with V-shaped posteroapical margin (as Brullea in fig. 202)............................ Metaglymma

- Antennomeres 3–5 with an apical ring of setae and remaining with pubescence all along the surface; glossal sclerite with right posteroapical margin (fig. 177)......................... Mecodema

4(1). Head with a single supraorbital puncture on each side; mentum with two deep paramedian foveae; almost always with two setae in the eustipes.......... 6

- Head with two or more supraorbital punctures on each side; mentum without fovea; three setae in the eustipes..... 5

5(4). Prothorax straightly compressed at the apex, second article of the maxillary palp with more than two setae (7–8); foreleg trochanter with one seta; abdominal sterna smooth....... Percosoma

- Prothorax not compressed at apex, second article of the maxillary palp bisetose; foreleg trochanter bisetose; abdominal sterna with two lateral foveae (in some cases slightly foveated)...... Oregus

6(4). Head with a transverse impression behind eyes, frontal grooves present...... 7

- Head without a transverse impression behind eyes; frontal grooves absent.......................... Percolestus

7(6). Without parascutellar setae on basal portion of second stria.............. 8

- With parascutellar setae on basal portion of second stria........... Diglymma

8(7). Scrobal mandibles without setae; prothorax with 4–6 setae on each side; parascutellar striole joined to the apical portion of stria 1............ Chylnus

- Scrobal mandibles with setae; prothorax with 1–3 setae on each side; parascutellar striole joined or isolated from the apical portion of stria 1.......... 9

9(8). Submentum with six setae; prothorax with more than one setae on each side; pronotum rounded, not constricted apically; male foretarsomeres 1–3 with adhesive vestiture..... Eurylychnus ( E. olliffi group)

- Submentum bisetose; prothorax with one seta on each side; pronotum constricted apically; male foretarsomeres without adhesive vestiture.............. 10

10(9). Parascutellar striole isolated from apical portion of stria 1; abdominal sterna without setae........................ Eurylychnus ( E. blagravii group)

- Parascutellar striole joined to the apical portion of stria 1; abdominal sterna with setae............... Nothobroscus
