Digrammia s-signata
Ferguson (2008) placed s-signata in the new genus Rindgea. (1)
Ferguson (2008) listed the forewing length. (1)
♂ 10-13 mm.
♀ 10-15 mm.
Adult: forewing off-white to pale yellowish or buff with strongly curved S-shaped black PM line; discal spot small or absent; AM line faint or sometimes absent; median line faint or absent; PM line interrupted by short space near costa, and edged distally by diffuse band of grayish=brown shading; hindwing same color as forewing but PM line is thin, brown, almost straight, and completely crosses wing.

Ferguson (2008) reported the species is restricted to Texas from San Antonio south to Coahuila, Mexico. He also mentioned one stray record from Colfax County, New Mexico in 1989.(1)
Rindge (1959) mentions the confusion over the specimens outside of Texas being called s-signata. Moths of Southeastern Arizona(2) has older specimens labeled s-signata.
The average flight period is February through November. (1)
The larvae have been reared on Prosopis glandulosa (mesquite). (1)
The S-signata group consists of three very similar species. Please see notes on the range which is often helpful in determining the species.
Rindgea ballandrata
R. cyda
R. s-signata
6/5/2022 by Ann Hendrickson:
I have just discovered an error in the naming of the Male genitalia in the Ferguson fascicle on Page 340. Since I have made all of my identifications from the Male genitalia, I have missed this for YEARS!
I made this discovery when I recently reared Rindgea s-signata for the FIRST TIME. The mother dissects as the Ferguson R. s-signata while 5 males from the brood dissect as the Ferguson named Rindgea cyda photographs b & d! That would indicate that the female dissections are the ones that are correctly named.
The caterpillar posted on BOLD as TXLEP669-19, BIN, BOLD:AAF0914 was beaten from a Mesquite tree and matches Rindgea cyda, however, it is not Barcode compliant as is the comparison specimen. All of my barcode compliant specimens match. I am hoping that when I submit three specimens that dissect as R.s-signata, they will not match the others!

In some areas of Texas where Rindgea cyda and Rindgea s-signata both occur together they can only be distinguished by genitalia. (1)
