Key to Afrotropical Temnothorax workers
This key to the workers of Afrotropical Temnothorax is based on Prebus (2015)[1].
1
- Compound eyes moderate in size: OI < 30. Head square CI > 8 => Temnothorax solidinodus
- Compound eyes large: OI > 30. Head elongate CI < 85 => 2
2
- In full-face view antennal scapes short, distinctly failing to reach posterior margin of head (Fig. 2a); SI < 80. In dorsal view postpetiole trapezoidal, widestvat the anterior 1/4 of the segment (Fig. 2c) => 3
- In full face view antennal scapes long, surpassing posterior margin of head by at least the length of the first funicular segment (Fig. 2b); SI > 80. In dorsal view, postpetiole widest at the anterior 1/3 of the segment (Fig. 2d) => 4
3
- Metanotal groove present (Fig. 3a); posterior margin of head shallowly but distinctly impressed (Fig. 3c) => Temnothorax megalops
- Metanotal groove absent (Fig. 3b), barely visible as an indistinct break in the sculpture dorsally in some specimens; posterior margin of head flat (Fig. 3d) => Temnothorax mpala
4
- Propodeal spines short: PSLI < 23 (Fig. 4a) => Temnothorax brevidentis
- Propodeal spines moderately long and acute: PSLI > 23 (Fig. 4b) => 5
5
- Antennal scapes long; surpassing the posterior margin of the head by the length of the first two funicular segments when fully retracted: SI 94–97 (Fig. 4c) => Temnothorax rufus
- Antennal scapes shorter; surpassing the posterior margin of the head by the length of the first funicular segment when fully retracted: SI 84 (Fig. 4d) => Temnothorax cenatus
