Stenamma californicum

Very Little is know about this species. The types were found in fern humus and a second collection is noted as being from the leaf litter in chaparral. Other collections have been taken in oak woodlands.

Identification
A relatively small and variable speices in the diecki group. Eyes with 3-5 facets in greatest diameter; thoracic rugulae coarse, close, interspaces moderately to strongly shiny; postpetiole shiny between rugulae; first tergite lightly punctulate on basal third or less; first sternite punctulate and firiely striolate, at least at sides. The sculptured first sternite, within this group, is shared with Stenamma dyscheres, but that species is usually larger, has distinct, rather coarse rugulae on the sides of the thorax, usually has distinct longitudinal striae on the first sternite and the first tergite is not distinctly punctulate.

Workers are uniformly light ferruginous with the sutures and margins a little darker.
