Curated Timema boharti from the CAS - Timema boharti - Male
Piñon Flat, Riverside County, California, USA

From the collection of the California Academy of Sciences
Collectors: MacNeill, Rentz, Brown, Lundgren
Cal Academy ID #: CASENT 8378615

Details of the collecting event are described in the one-page article:

Rentz, D. C. (1963). Notes on a collection of Timema boharti Tinkham, Pan-Pacific Entomologist 39(2):74
Specimens of Timema become discolored with age. From that article, the overall "live" color before being collected was either (mottled) gray or green.

Comparison with the Culp Valley Timema
The terminalia here are indeed very similar to those of the Culp Valley population as can be seen from the full-size images accessible via the posts below:

           

In the (full-size version of the) 1st image above, the terminalia agree quite well with those of the CAS specimen.

In the 2nd and 3rd images, the dextral cercus appears to be slightly longer; perhaps a bit more mildly and uniformly curving; and more sharply left-leaning (or "in-bent")...though the latter may simply depend on how the male voluntarily positions that cercus at a given time.

In the 3rd, beige morph male, the intra-dextral process appears nearly lacking in teeth along the visible portion of its dextral edge...whereas all three of the others have more conspicuous teeth there.

In both the CAS image and the 2nd image, the inner apical corner of the intra-dextral process can be seen to have a small, "hook-like" emargination...similarly-shaped in both individuals. (Note that in the other two images the view of the inner apical corner of the intra-dextral process is blocked by the sinistral cercus).

Overall, it seems the terminalia characters of all 4 individuals are quite similar...with the variation among the three specimens from Culp Valley greater than that between any one of them and the CAS specimen.

The CAS specimen is highly discolored compared to it's original state when alive. But it's perhaps worth noting that what's visible of the the mottling pattern there looks somewhat different from the morphs photographed at Culp Valley. The same is true for other CAS specimens I looked at. But color and pattern can often vary significantly within a single Timema species.
