Synonyms and other taxonomic changes
Timema poppensis Vickery & Sandoval, 1999 [Note: This original epithet was incorrectly formulated per ICZN rules and should not be used going forward, see this forum for details]
Timema poppense [This is the emended spelling, with the epithet in neuter form agreeing with the neuter genus name. This is the form (spelling) that should be used per ICZN rules.]
Explanation of Names
The epithet refers to the area of the type locality near Pope Valley in Napa County, CA. (Why a "double p" was used in the spelling of the epithet is unclear...perhaps an error?)
Identification
Both males and females are a luminous green with three narrow, darker-green (longitudinal) stripes along the dorsum of the abdomen (one medial, and another on each side).
Confident ID should be strongly supported by a good match with nuances in the shape of the terminalia (especially the male's) to that shown for T. poppense in the reference figure below (4th entry on left):
 
Range
The distribution for T. poppense shown on the map here should be considered a subset of the actual range, since the interactive map here indicates further records of T. poppense in the Coast Ranges in Marin Co. and as far north as Humboldt Co.
Food
Recorded host plants: douglas fir (Pseudotsuga menziesii), coast redwood (Sequoia sempervirens)
Remarks
Original description in Vickery & Sandoval (1999).
