Key to New World Tillinae genera updated and modified from Opitz (2002)
1. Frons with a pair of protruding horns arising immediately above eyes................................ Bostrichoclerus View in CoL
- Frons without a pair of horns............................................................................ 2
2. Last antennomere as long as to much longer than length of preceding antennomeres combined ( Fig. 1 View FIGURE 1 -E); eyes strongly emar- ginate...................................................................................... Monophylla View in CoL
- Last antennomere not enlarged, never as long as or longer than the length of preceding antennomeres combined, all antennom- eres approximately the same length ( Figs. 1 View FIGURE 1 A–D, 1-F); eyes emarginate ( Figs. 2 View FIGURE 2 -C, 2-D) or not....................... 3
3. Head subquadrate, enlarged; clypeus conspicuously wide; antennomeres 5–11 or 6–11 subquadrate, conspicuously wider than antennomeres 1–4 ( Fig. 1 View FIGURE 1 -G) or 1–5 ( Fig. 1 View FIGURE 1 -H); body relatively slender; elytra subparallel; integument smooth to glossy................................................................................................... Cylidrus
- Head not subquadrate, if conspicuously enlarged throughout its length, distal antennomeres approximately the same width as remaining antennomeres ( Figs. 1 View FIGURE 1 -A, 1-B, 1-D); body slender to robust; elytra subparallel or not; integument smooth to coarsely punctate............................................................................................. 4
4. Antennae strongly serrate ( Fig. 1 View FIGURE 1 -D) to pectinate ( Fig. 1 View FIGURE 1 -C).................................................... 5
- Antennae filiform ( Fig. 1 View FIGURE 1 -A) to moderately serrate ( Fig. 1 View FIGURE 1 -B)................................................... 7
5. Last antennomere as preceding antennomere in shape; antennomeres 4–10 strongly serrate ( Fig. 1 View FIGURE 1 -D); length of specimens approximately 10 mm or more...................................................................... Bogcia View in CoL
- Last antennomere flattened laterally, ovoid; antennomeres 4–9 or 4–10 moderately serrate ( Fig. 1 View FIGURE 1 -F) to pectinate ( Fig. 1 View FIGURE 1 -C); length of specimens less than 8 mm ....................................................................... 6

9. Elytral punctations coarse, extending to apex ( Fig. 3 View FIGURE 3 -B)............................................... Lecontella View in CoL
- Elytral punctations feebly to moderately coarse, not extending to apex ( Fig. 3 View FIGURE 3 -A); if punctations extend to apex, then these are shallow and feebly impressed.......................................................................... 10
10. Diameter of ommatidia narrow ( Figs. 2 View FIGURE 2 -A, 2-B); integument in two colors: testaceous to ferruginous and brunneous to black; eyes weakly emarginate and elongate-ovoid, in lateral view much taller than wide ( Fig. 2 View FIGURE 2 -B); small species, length less than 8 mm ...................................................................................... Cymatoderella View in CoL
- Diameter of ommatidia wide ( Figs. 2 View FIGURE 2 -C, 2-D); integument unicolored to variously colored; eyes weakly to moderately emarginate, in lateral view form variable, ranging from much taller than wide to almost round ( Fig. 2 View FIGURE 2 -D); species 4–40 mm in length..................................................................................... Cymatodera View in CoL
