Stenamma huachucanum

Rarely collected. A few collections have come from under stones. One of these was from an area at the edge of a pine-fir woodland and the other from on an open slope. A worker was also found in a leaf litter sample taken from an oak-pine-juniper woodland.

Identification
The species is distinguished by the following characters: Small eye for a Stenamma, the greatest diameter of which is approximately 0.10 mm and has 5-7 ommatidia; very weakly developed dypeal carinae and mesoepinotal impression; pair of extremely smaIl (almost vestigial) tuberculate epinotal spines; the unusually high petiolar node which is much compressed anteroposteriorly; base of gaster almost destitute of longitudinal rugulae, these when present or well developed apparently never exceeding 0.05 mm in length; bicolored appearance, and the delicate sculpturing of the body.
