Identification
The easiest field character for separating the two species involves the color of the integument surrounding the spiracle: concolorous pale in F. spinosula versus dark brown in F. aptera. Male parameres are distinctly clavate, as opposed to the slender, digitate parameres of F. aptera.
On average, F. spinosula tends to be a little longer and more slender than its congener. The pronotal armature is variable, and overlaps with F. aptera, but in F. spinosula, there are usually two submedial tubercles and a tubercle at each humeral angle.
