Adelomyrmex brenesi 2006: 132, figs. 1–3. Holotype worker: Costa Rica, Heredia Prov., 6 km ENE Vara Blanca (10 ° 11 ' N, 84 ° 07' W), 2000 m elevation, 13. III. 2002, (Project ALAS) [specimen code JTLC 000003382] [ INBio] (examined).

Geographic range. Costa Rica.

Biology. This species is still only known from the material reported in Longino (2006). It is a montane endemic, known only from the peak of Volcan Barva. This is a forested mountaintop of relatively small area in the Cordillera Volcánica Central of Costa Rica. Adelomyrmex brenesi is restricted to a narrow elevation range at the very top of the peak, around 2000 m, and does not occur at lower elevations ( Longino & Colwell 2011). In a quantitative inventory at this site, it occurred in 13 of 150 miniWinkler samples. This is a species clearly in danger of mountaintop extinction due to climate change ( Colwell et al. 2008).
