I collected this 380-micron oribatid from oak-manzanita leaf litter using a Tullgren funnel, some photos taken at the California Academy of Sciences.

Dave Walter was kind enough to look at these images as posted to the Acarology FB page and commented: "You need to work out the porose/saccule system and make sure you aren't confusing internal thickenings with a translamella. Maybe Ceratozetoidea, or Achipteroidea, or Oribatelloidea. I can't tell from your images, but there is at least a long medial cusp on the lamella and if there is a long lateral cusp too, then I would lean towards the latter - but this section of the 'higher' oribatids is the most species diverse and they play around with their morphology. The Almanac key would be good to superfamily and probably family".

Found this on a Merritt College Herpetology class field trip. The USGS who was conducting surveys in the area and studying the giant garter snake took our class along on a hike to witness some of their field work. It was really neat to see them install a radio transmitter into the snake so that they could monitor its movements. I highly recommend the class to anyone in the area. There will be another class this Fall 2013 semester, BIO 61D Fall Herpetology class code 40130. To apply and enroll visit the website www.peralta.edu and if you have any questions just ask me.
