sF Ponerinae Anochetus
Anochetus is a common predator of the litter and canopy. I have not collected three of the following taxa--bispinosus, mayri, and striatulatus--but have included them based on their geographic distribution (Costa Rica and at least one collection in South America). I have records of an additional unmatched male under the morsphospecies "BCILT1". Most of this material is borrowed from Jack Longino's Anochetus pages.
Species are sorted by head length (HL, maximum length of head in full face view, including mandibles).
HL=1.75
petiolar node as seen from the front or rear with apical margin distinctly concave, the 2 free corners forming angles or produced as teeth; second segment of antennal funiculus less than twice as long as broad.
HL=1.75-2.2
petiolar node as seen from the front or rear with apical margin distinctly concave, the 2 free corners forming angles or produced as teeth; second segment of antennal funiculus more than twice as long as broad; compound eyes greater than 0.08mm greatest diameter.
HL=X.XX
HL>2.2
medial borders of mandibles with two or more prominent, serially arranged teeth (in addition to the 3 teeth at apex).
HL=2.53
medial borders of mandibles without prominent teeth proximal to the single preapical tooth or angle; petiolar node as seen from the front or rear with apical margin distinctly concave, the 2 free corners produced as teeth; second segment of antennal funiculus at least twice as long as broad; eyelength greater than 0.08mm; pronotum irregularly rugose; striae on face relatively coarse; propodeal spines spiniform
Extremely rare
