Keys to species of Bannapone based on Eguchi et al. (2015).

Worker Key

Bannapone mulanae is excluded from this key because the worker remains unknown.

1

2

  • Mid-basal tooth row of mandible consisting of 2 blunt teeth; frontal lobes relatively distinctly separated by posteromedian portion of clypeus => Bannapone scrobiceps
  • Mid-basal tooth row of mandible consisting of 4–5 blunt or truncate teeth; frontal lobes closely approximated => 3

3

  • Mid-basal tooth row consisting of 5 teeth of which basal four almost equal in size; preapical denticle of apical blade of mandible developed well => Bannapone pertinax
  • Mid-basal tooth row consisting of 4–5 teeth which decrease in size toward base; preapical denticle of apical blade of mandible absent or reduced => 4

4

  • Frontal carinae conspicuous, reaching vertex; 9th and 10th antennal segments each a little longer than broad; posterolateral part of propodeum strongly produced posteriad => Bannapone cryptica
  • Frontal carinae inconspicuous, extending by no more than the length of frontal lobe; 9th and 10th antennal segments each (a little) shorter than broad; posterolateral part of propodeum feebly produced posteriad => 5

5

Queen Key

Bannapone fulvida, Bannapone pertinax, Bannapone scrobiceps and Bannapone zwaluwenburgi are excluded from this key because the queens remain unknown.

1

  • Mid-basal tooth row consisting of 4–5 blunt teeth; distance between median ocellus and lateral ocellus as long as or shorter than that between lateral ocelli => 2
  • Mid-basal tooth row consisting of 2 blunt teeth; distance between median ocellus and lateral ocellus longer than that between lateral ocelli => Bannapone mulanae

2

  • Anteromedian portion of clypeus lacking a pair of extremely long and flexible setae; frontal carinae inconspicuous, extending by no more than the length of frontal lobe => Bannapone caliginosa
  • Anteromedian portion of clypeus bearing a pair of extremely long and flexible setae; frontal carinae conspicuous, reaching vertex => Bannapone cryptica
