Pheidole biolleyi
Pheidole Biolleyi Forel, 1908: 48 . LECTOTYPE major worker (here designated): Costa Rica, La Palma, 1600 m (P. Biolley) [MHNG, unique specimen identifier JTLC000014077, examined].
Pheidole Biolleyi subsp. Tristani Forel, 1908: 50 . LECTOTYPE major worker (here designated): Costa Rica, Cartago, 1450 m (Biolley) [MHNG, examined]. Synonymy by Wilson, 2003: 170.
Comments. The syntype series of P. biolleyi subsp. tristani consists of two species. A major worker, designated here as the lectotype of tristani, is the same as P. biolleyi and maintains Wilson's synonymy of tristani under biolleyi . A minor worker from Santa Maria de Dota is identified here as the new species P. tinamu . I chose to maintain the synonymy by making the major worker the lectotype, rather than making the minor worker the lectotype and resurrecting P. tristani, so that P. tinamu could have a major worker as a holotype and be based on a full type series of fresh material.
