Cisthene subrufa (Barnes & McDunnough, 1913)
Ozodania schwarziorum [In Part] Dyar 1899
[In Part] Hampson 1900(1)
Barnes & McDunnough, 1913(1)
Phylogenetic sequence # 930176
Lafontaine & Schmidt (2010) included twenty species of the genus Cisthene
in North America north of Mexico. (2)
Identified by range and a combination of characters(4)
-- Pale creamy yellow rather than orange color areas.
-- Basal streaks stop well short of the PM band; margins of the basal streaks are convex, resulting in an elliptical pale area surrounding the thoracic disk, like an avocado cut in half.
-- Ground color is brownish gray.
-- PM band flares out much wider on inner (upper) margin compared to costal margin. PM band usually complete but may be split into triangles on each margin; the one on the inner margin always larger than the costal one.
-- Leg color is useful: Hind legs are usually all yellow; middle legs are banded yellow and gray, particularly the middle tibia on which the middle 1/3 is yellow, flanked by gray on each end.
-- Small size (FW 5.5 to 7 mm).
Originally described from Cameron Co., TX.(1)(3)
Now documented uncommonly north to Bastrop, Travis, and Edwards counties in Texas. Occurs south into Mexico at least as far as e. San Luis Potosi (iNaturalist)(4)
Subtropical Thorn Woodland in south Texas.
Wagner et al. (2008) collected larvae from Psychia lichens on Texas Ebony (Ebenopsis ebano).
Previously confused with Schwarz's Lichen Moth
of AZ, but the ranges of the two are well separated. Previous reports of the species in AZ (e.g. MPG, Wikipedia) were based on that species.
Thin-banded Lichen Moth
is slightly larger, less suffused with brown scales, and ranges outside of Texas.(1)
The basal orange streak nearly or actually reaches the PM band and the PM band is usually narrow and doesn't have the "top-heavy" width shown on Tamaulipan.
One-banded Lichen Moth
can be similar but color bands are usually pale orange rather than pale yellow; basal streak almost always touches the PM band; and the PM band is about equally wide where it meets the inner and costal margins.
