Identification
Members of Derotmema can be distinguished from other Oedipodinae by their banded wing patterns, though specific diagnostic features for the genus itself require examination of morphological characters not detailed in available sources. The genus is placed in tribe Psinidiini, which may help differentiate it from band-winged grasshoppers in other tribes such as Trimerotropini or Arphiini.

Human Relevance
Hayden's (Derotmema haydeni) is included in the Field Guide to Common Western Grasshoppers, indicating it is recognized as a of interest for regional entomological surveys and grasshopper management in western rangelands.
Similar Taxa
- TrimerotropisBoth belong to Oedipodinae and possess banded wings; Trimerotropis is more -rich and widely documented, while Derotmema contains fewer species and is less frequently encountered in field studies.
- ArphiaAnother Oedipodinae with banded wings; Arphia such as A. conspersa and A. pseudonietana are common western grasshoppers that may be confused with Derotmema species based on general appearance.
