Diagnosis.
S. furcata
can be distinguished from other members of the
furcata
group by its sparsely clothed and finely punctate pronotal disc, which is more strongly gibbose in lateral view than are those of the other species, and its tuberculate prosternum.
Remarks.
Triplehorn and Brown (1971)
presented the first records of
S. furcata
within the
United States
and discussed variation within and between
S. furcata
specimens from differing localities. They examined differences in elytral sculpturing and marginal carina bifurcation between populations and concluded that, while there are slight geographical variations, all of the observed variation fell within the range of
S. furcata
.
