DISCUSSION

This small subterranean species is poorly known. Not surprisingly most of these collections were from under partially buried stones; the Glamis sample consists of a single specimen taken from a foraging worker of Forelius maccooki (Forel) HNS and the Lucerne Valley record is based on a head capsule recovered from a refuse midden of Solenopsis xyloni McCook HNS . The Red Cloud Canyon site is in a rocky streambed on the west side of the range, in Creosote / Cactus Scrub desert. The specimens were collected in late afternoon beneath a partially buried stone. There had been rain several days prior to the collection and the soil under the stone was slightly damp. The Havasu Canyon collection was made under similar circumstances.

Neivamyrmex nyensis HNS may eventually prove to be the worker form of N. mojave HNS .
