Description
A member of the diligens group, close to Pheidole longiscapa and Pheidole rochai, and distinguished by the following set of traits.
Major: antennal scape exceeding the occiput by 2! the scape maximum width; propodeal spines half as long as the propodeal basal face anterior to them; anterior margin of propodeum rugulose; carinulae absent from genae.
Minor: scapes exceed occipital corner by half their length; propodeal spines half as long as the basal propodeal face; anterior margin of the pronotum transversely carinulate; mesonotal convexity tilted forward on mesonotum, subangular, and marginally carinulate.
MEASUREMENTS (mm) Holotype major: HW 1.00, HL 1.02, SL 0.96, EL 0.20, PW 0.54. Paratype minor: HW 0.60, HL 0.74, SL 1.10, EL 0.16, PW 0.46.
COLOR Major and minor: concolorous dark yellow.
Figure. Upper: holotype, major. Lower: paratype, minor. Scale bars = 1 mm.
Type Material
COSTA RICA: La Selva Biological Station, near Puerto Viejo, Heredia, col. E. O. Wilson. Museum of Comparative Zoology
Etymology
Gr tanyscapa, with stretched-out stem, alluding to the elongated antennal scape.
