Comments

The minor of Pheidole angusticeps HNS has a narrow head, with CI 80-83. In the description of Pheidole gradifera HNS the minor is reported to have CI 94 and the line drawing shows the head about as long as wide. However, this must be due to measurement error; the types of P. gradifera HNS are typical P. angusticeps HNS , and the minor worker has a narrow head.
