Species: Hypoponera ca01

Distribution:

Widespread in California at lower elevations. Outside California: Nevada, Arizona, northwestern Mexico.

Biology:

This species has been collected widely in California, from chaparral, grassland, sagebrush scrub, oak woodland and riparian woodland. It prefers drier microsites than H. opacior, but the two species can be found nesting within a few meters of one another. The reproductive females are ergatoid (worker-like).

Identification:

Worker: similar to Hypoponera opacior (q.v.) except as follows: standing pilosity common on venter of head (sparse in California populations of H. opacior); head narrower, CI 0.77-0.83 (versus 0.83-0.87 in H. opacior); petiole less slender; body color orange-brown (usually dark brown in H. opacior).

Comments:

Might be Hypoponera foeda (Forel, 1893).
