"Gena punctation";"♀: Gena with shallow punctation, more sparsely spaced by uneven interspaces that can reach the diameter of one puncture.";"♀: Gena with coarse and dense subcontiguous punctation, with narrow linear interspaces.";"♀: Gena with coarse and dense subcontiguous punctation, with narrow linear interspaces."
"♂: Gena with remarkably minute and sparse punctuation, its lower half with large and almost impunctate area near outer orbit (Fig. 17).";"♂: Gena with coarse subcontiguous punctuation, its lower half uniformly punctate, at most with a small impunctate area (Fig. 14).";"♂: Gena with coarse subcontiguous punctuation, its lower half densely punctate, at most with a small impunctate area (Fig. 20)."

"Mesepisternum punctation";"Punctation sparse, punctures separated by conspicuous flat interspaces (dense around scrobal area) (Fig. 19).";"Punctation subcontiguous, mostly with linear to carina-shaped interspaces (Fig. 16).";"Punctation subcontiguous, mostly with carina-shaped interspaces (Fig. 22)."
Metasoma;"Punctation of terga 2–4 fine and remarkably sparse (most interspaces > 1–2 puncture diameters) with conspicuous micropunctation in-between, tegument smooth and shiny (Fig. 18).";"Punctation of terga 2–4 denser (interspace ≤ 1 puncture diameter) and somewhat coarser so the segment appears matte, micropunctation hardly distinct, tegument of terga smooth, at most slightly shagreened basally (Fig. 15).";"Punctation of terga 2–4 denser (interspace ≤ 1 puncture diameter) and coarser so the segment appears matte, micropunctation hardly distinct, tegument of terga shagreened, at least basally (Fig. 21)."
