Caution: There may be wild species of this genus not yet included in this guide.
L. californicus was originally described as a subspecies of L. cinctus. I’m not sure when it was promoted to full species status, but there is an ongoing debate whether the two groups can be separated at all. In any case, I can’t find an electronic copy of the 1923 paper (or any other) that describes the supposed difference between the two groups. Some sources [source] claim that L. californicus is up to 25 mm long, whereas L. cinctus and L. succinctus are no more than 13 mm long.
L. succinctus is often IDed in CA, but supposedly it is only found east of the Rockies.
Bugguide.net claims that someone is reviewing the genus [source], so perhaps they’ll publish a clarification in the future.
