Countries Occupied

Number of countries occupied by this species based on AntWiki Regional Taxon Lists. In general, fewer countries occupied indicates a narrower range, while more countries indicates a more widespread species.

Estimated Abundance

Relative abundance based on number of AntMaps records per species (this species within the purple bar). Fewer records (to the left) indicates a less abundant/encountered species while more records (to the right) indicates more abundant/encountered species.


R. minuchae is an obligate slave-making ant that enslaves workers of Proformica longiseta (Ruano & Tinaut, 1999; D'Ettorre & Heinze, 2001; Errard et al., 2006; Ruano et al., 2013; de la Mora et al., 2021). Both species are endemic to the high mountains of southern Spain, but while P. longiseta is common, R. minuchae is rare and with limited distribution (Ruano & Tinaut, 1999).

Behavioural observations and limited nest excavations revealed that sexuals are not produced every year, the number of sexuals is low, and the sex ratio tends to be female biased (Ruano & Tinaut 2005). Queens typically exhibit two distinct activity periods. First, the mating period takes place in early afternoon: queens “call” near the natal nest, mate and then re-enter their nest. Second, the dispersal period takes place in late afternoon: the mated queens exit their nest and fly in search of a new, non-parasitized Proformica longiseta host nest.
