Sharaf et al. (2016) - Granivorous species. It prefers open and dry habitats including pastures, shores of artificial lakes, seashore with phrygana, abandoned gardens, but also found in limestone gorges with Platanus trees, open pine forests and open oak woodlands. Nests are built directly in the ground and under stones. Lowland species, the highest locality in Greece was recorded at about 570 m a.s.l. (L. Borowiec pers. comm.).
Sharaf et al. (2016) - Trichomyrmex abyssinicus and Trichomyrmex perplexus can be distinguished from other Arabian species by the vertical ellipse or slit propodeal spiracle. Trichomyrmex abyssinicus is similar to T. perplexus but can be separated from it by the convex promesonotum outline, the distinctly longer propodeal dorsum, and the irregularly rugulose propodeum, petiole and postpetiole.
Keys including this Species
Sharaf et al. (2016) - Trichomyrmex perplexus was described from Armenia and recorded from United Arab Emirates (Collingwood et al. 2011), the Middle East including Jordan, and Syria (Borowiec 2014), Eastern Europe and from the Mediterranean Basin including Greece, Turkey, and Cyprus (Borowiec 2014). It is common in the Aegean Islands, Crete, Macedonia, Dodecanese Islands, Ionian Islands, and Thessaly (Borowiec & Salata 2012, 2013; L. Borowiec pers. comm.).
