Pheidole hoelldobleri  HNS  new species

Types INBio.

Etymology Named in honor of the distinguished biologist and student of Costa Rican ants Bert Holldobler.

diagnosis A bicolorous member of the diligens  HNS  group whose majors have angulate humeri; thin propodeal spines; long, sparse pilosity; rugoreticulum mesad to the eyes; and shagreened anterior fourth of the first gastral tergite.

Close to coffeicola  HNS  , but differing in color and many details of sculpturing as shown.

measurements (mm) Holotype major: HW 1.24, HL 1.24, SL 0.94, EL 0.20, PW 0.56. Paratype minor: HW 0.70, HL 0.86, SL 1.06, EL 0.14, PW 0.44.

Color Major: bicolorous, with gaster dark, almost blackish brown and rest of body and appendages dark reddish yellow. Minor: bicolorous, with gaster medium brown, rest of body and appendages dark brownish yellow. Range Atlantic and Pacific slopes of Costa Rica (Longino 1997).

Biology Longino (1997) states that hoelldobleri  HNS  "occurs in wet forest habitats, either in the canopy of mature forest or in small trees of young second growth, where it nests opportunistically in cavities in live stems, and in the forks of small trees. It may use accretal soil as nest material." He obtained specimens by fogging in the canopy of the forest of the La Selva Biological Station, as well as from guava (Psidium) and Cecropia trees along roads and in pastures.
