Puncture size: large = 0.17 mm or larger;
moderately large = 0.08-0.17 mm; moderate =
0.03-0.08 mm; small = 0.03 mm or smaller.
Setae density: dense = setae completely
cover and obscure body surface; moderate =
setae completely cover body surface but surface
clearly visible; sparse = setae do not cover
body surface and surface clearly visible.
Protibial teeth: protibial first tooth = the
apical tooth on the protibia; protibial second
tooth = the second tooth from the apex of the
protibia; protibial third tooth = the third tooth
from the apex of the protibia.
Adult Morphological Character
Analysis
Puncture size and density, and several
other character states are defined in “Character
Definition” section. The complete character
matrix is in Appendix 1.
1. Clypeal disc glabrous (or with a few
sparse lateral setae) (0); sparsely setose
over whole surface (1); sparsely setose laterally
(2); sparsely setose apically (3).
2. Clypeal apex not reflexed (0); reflexed (1).
3. Clypeal apex rounded (0); broadly
rounded (1); weakly trapezoidal (2); distinctly
trapezoidal (3); rectangular (4).
4. Frontoclypeal suture complete (0); incomplete
(1).
5. Frons base sparsely punctate (0); moderately
to densely punctate (1).
6. Frons medioapically not depressed (0);
depressed (1).
7. Frons glabrous (0); scattered lateral setae
(1); sparsely setose laterally (2); moderately
setose (3).
8. Eyes well-separated from pronotum (0);
touching pronotum (1).
9. Eyes well-separated (more than 4.7 transverse
eye widths) (0); closer together (less
than 4.5 transverse eye widths) (1).
10. Antenna 10-segmented (0); 9-segmented (1).
11. Antennal club (males) longer than or approximately
equal to other segments (0);
slightly shorter than other segments (1);
approximately equal to segments 2-6 (in
9-segmented individuals) or 2-7 (in 10segmented
individuals) (2).

other segments (1); slightly shorter than
other segments (2); approximately equal
to segments 2-6 (in 9-segmented individuals)
