The specimens were taken sorting mixed deciduous and redwood leaf litter. Tiny, litter-dwelling arthropods active in winter are rarely collected so it may be expected that this species has a wider range in the San Francisco Bay area, and that congeners may exist in similar habitats north and south along the coast.

is strikingly different from other caseyid species. Its small size and metazonital tubercles carrying the lateral metazonital setae set it apart; the smallest previously known caseyids are twice as large and all previously known caseyids have cylindrical metaterga without lateral tubercles. The male third legpair lacks the characteristic ventrally extended coxae found in all other caseyids and occuring as well in the related striariids and urochordeumatids. The gonopods are unlike those of most caseyids in their simplicity and lack of flagellocoxites; these characters may be related to simplification connected to small size.
