Temnothorax algiricus

Dichotomic key to the worker caste of the Temnothorax algiricus complex

- Spines more erect [SpANG: 112.4 (106, 118)] and longer [ SPST /CS: 0.458 ( 0.425, 0.485)], a stark angulate discontinuity between the dorsum and the steep posterior declivity and PropH2/Proph1: 0.794 ( 0.722, 0.878). Only Algeria and Morocco.............................................................................................. T. trabutii

- Spines forming a larger angle with the mesosoma (SpANG 119 to 161) and shorter ( SPST /CS 0.201 to 0.409), propodeal declivity absent or less steep, without a more gentle transition of the dorsal profile.................................. 2

2. Spines forming a smaller angle with the mesosoma [SpANG: 130.24 (119, 139)], are on average longer ( SPST /CS: 0.329 [ 0.261, 0.409]) and less divergent dorsally [ SPWI / SPST: 0.829 ( 0.628, 1.2222)]. In many regions, entirely dark colored colonies are prevalent, but others have the same reddish component of the other two species. North Africa, southern Iberia, Balearic Islands, Italy (including Sardinia, Sicily and minor islands), Corsica, Croatia..................................... T. algiricus

- Spines forming a larger angle with the mesosoma [SpANG: 147.5 (141, 161)], are on average shorter ( SPST /CS: 0.283 [ 0.201, 0.364]) and more divergent dorsally [ SPWI / SPST: 1.060 ( 0.847, 1.307)]. Algeria, Morocco, Iberia and mainland France, unknown on islands............................................................................ T. atlantis
