Description
DIAGNOSIS A highly distinctive species with some resemblance to Pheidole arietans, Pheidole glyphoderma and Pheidole triumbonata, but instantly recognizable by the unique pattern of sculpturing, especially on the minor worker, as illustrated.
MEASUREMENTS (mm) Holotype major: HW 1.98, HL 2.12, SL 0.90, EL 0.24, PW 0.86. Paratype minor: HW 0.74, HL 0.80, SL 0.84, EL 0.20, PW 0.50. ectatommoides COLOR Major: head, meso soma, and waist light reddish brown; appendages and gaster reddish yellow.
Minor: head and meso soma reddish yellow; waist, gaster, and appendages plain medium yellow.
Figure. Upper: holotype, major. Lower: paratype, minor. Scale bars = 1 mm.
Type Material
COSTA RICA: Rio Toro Amarillo, near Guapiles, col. William L. Brown. Museum of Comparative Zoology
Etymology
L ectatommoides, referring to the distinctive sculpturing of the minor especially, reminiscent of ectatommoid ponerine ants.
