Isotoma with short antennae? - Isotomurus palustris Presidio, Rob Hill Campground, San Francisco County, California, USA January 23, 2021 Size: 1.5-2.0 mm
Found under a rock and collected. The markings resemble Isotoma, but the short antennae and other features had me key this (incorrectly, I assume) to Neanuridae in the helpful key at collembola.org : "Key to the common surface dwelling Collembola from North America". Some sort of young or aberrant Isotoma?
