Identification
Texananus can be distinguished from related deltocephaline leafhoppers by a combination of genitalic characters, particularly male aedeagal structure and female sternite VII shape. Within the tribe Scaphoideini, Texananus is characterized by specific wing venation patterns and that separate it from the closely related Scaphoideus. Accurate species-level identification requires examination of internal genitalia under magnification.

Human Relevance
Texananus have been documented in agricultural research contexts. Texananus incurvatus was specifically studied for its on virus-infected versus healthy plants, suggesting potential involvement in plant virus transmission dynamics. The may have economic significance in crop systems, though specific pest status for most species remains undocumented.
