Identification
Distinguished from other Attalus by the distinctly elytral surface (not smooth or only punctate). The combination of reddish-orange coloration with dark elytral markings, small size, and granular texture separates it from A. scincetus (smoother ) and A. circumscriptus (different color pattern and punctation). Male genitalia provide definitive identification.
Appearance

Coloration predominantly reddish-orange to yellowish-orange with variable dark markings, often including a dark transverse band or spot pattern on elytra. Pronotum usually paler than elytra. Elytra surface distinctly or punctate-granular, giving a rough texture. relatively long, . Legs slender, yellowish to reddish.
