Synonyms and other taxonomic changes
Trimerotropis bernardi Rentz & Weissman 1984. Type locality: San Bernardino Mountains, California.
Explanation of Names
Only tentatively treated here specifically as distinct from Trimerotropis verruculatus
Similar to Circotettix splendidus, with which it is sometimes found, but smaller with wings narrower and hind wing with a more pronounced and evenly shaped dark cross band. Radial veins of hind wing are narrower. Sound produced in flight is a loud harsh crackle, but not so loud as C. splendidus, and also lacking the buzzing element that species sometimes produces along with the snapping and "crackling".
Much like Trimerotropis verruculata suffusa, except wings average proportionately somewhat shorter; color pattern usually white to pale gray with darker speckling/marbling; hind wings with apical area usually transparent or only slightly smoky.
Known only from the area of Valley of the Falls, San Bernardino Mountains, San Bernardino County, California
Gravelly to rocky areas, prefering areas that are recently disturbed or steeply sloping, often in assocation with open Pine forest.
The behavior and flight crepitation are as in closely related species of Trimerotropis (T. verruculata, T. cyaneipennis, T. fratercula, etc.), but location and coloring will help identify this species. It's pale cryptic coloring blends well with the pale rocks that dominate it's environment.
This is very closely related to T. verruculata, and distinction as a different species might be debatable. It is actually extremely similar to T. verruculata verruculata in characteristics, and it seems subspecies status might make more sense. Based on appearance, one wonders if it might have resulted from a blending over time of genes from Circotettis spendidus into a local population of T. v. suffusa.
This "species" seems to be restricted to a very small area, and should probably be considered as vulnerable.
