Timema boharti

The distinctive male terminalia are illustrated in Fig. 1 here . The female terminalia have the apex of the last (10th) tergite shallowly-notched (or emarginate), as emphasized in the keys in both Vickery (1993) and the earlier paper by Tinkham (1942)...see here . Note that in other species, like T. californicum , females also have the the apex of the 10th tergite notched...but subtleties in the size and shape of the notch and terminalia can still allow them to be distinguished.) Tinkham's detailed original 1942 description, based on two specimens from Borrego can be read here . Note however that, at the time Tinkham was writing, the occurrence of distinct intraspecies color forms in many Timema taxa was not yet known. Rentz, writing 21 years later, discussed a large series of T. boharti he had collected in the Pinyon Flats area of the Santa Rosa Mountains: The habitat is xeric pinyon-juniper with chaparral intrusions, and the T. boharti were taken at approximately 3000 feet. The entire series of specimens was taken at night. Mating pairs as well as last instar nymphs, some moulting, were found. Heretofore, this species was known only in the grey color phase. This timema, however, is dichromatic as are most other species in the genus. Green and grey color phases were taken with no indications of intermediates. It was of particular interest that mating pairs were segregated by color. Specimens were found on Yucca schidigera, Y. whipplei , Pinyon Pine ( Pinus parryana ), and a single pair was taken in copulo on Eriogonum fasciculatum . The majority of specimens was taken on Y. whipplei . The arcid odor commonly released by timema when handled was quite noticeable...
