Description
DIAGNOSIS A member of the transversostriata group, closest to Pheidole gnomus of Ecuador, distinguished in the major by the broad swath of transverse carinulae covering the posterior third of the head, but unlike those of gnomus, they are less extensive and do not curve downward to the sides; also, the pronotum is completely smooth and shiny and lacks anterior carinulae.
MEASUREMENTS (mm) Holotype major: HW 0.72, HL 0.88, SL 0.40, EL 0.10, PW 0.34. Paratype minor: HW 0.38, HL 0.44, SL 0.40, EL 0.06, PW 0.24.
COLOR Major and minor: concolorous clear medium yellow.
Figure. Upper: holotype, major. Lower: paratype, minor. Scale bars = 1 mm.
Type Material
PERU: Cuzco Amazónico, 15 km northeast of Puerto Maldonado, Madre de Dios, col. Stefan Cover. Museum of Comparative Zoology
Etymology
Gr scolioceps, bent head, alluding to dorsal profile of major.
