Hi folks. I sorted this little guy up to genus Sphaeroderus. I'm having a hard time getting to the species.
I'm using Lindroth work: I am including some couplets to help you guys sorting out the puzzle. I just couldn't.

1. Elytra each with 11—12 deep and regular striae. Palpi and tarsi yellowish brown 1. S. canadensis
— Elytra each with 14—16 less regular striae. Palpi and tarsi piceous to almost black '2

2. Prothorax with sides evidently sinuate before the little rounded, almost right hind-angles; lateral raised bead little widened in basal half. Elytra with at least intervals 4, 8 and 12 carinate and little interrupted in basal half. Penis very slender
(fig. 22 d), apex (in dorsal view) not truncate. L. 14—17 mm. N. Carol., Tenn
S. multicarinatus Darl.
— Prothorax with sides at most very faintly sinuate, hind-angles strongly obtuse and much rounded; lateral bead broadening basad. Elytra with no, or repeatedly interrupted carinae in basal half. Penis shorter, apex ± truncate (figs. 22 a—c) . . 3

3. Also sides of presternum (episterna) with a few coarse punctures medially. Prothorax
with basal foveae obscurely limited laterally; the coarse, confluent punctuation
reaches the lateral bead. Penis apex bent ventrad (fig. 22 a) . . 3. S. nitidicollis
— Prosternum with punctures restricted to the basal part (epimera) of sides. Basal foveae of prothorax separated from lateral bead by a convexity that is smooth or carries a few scattered punctures. Penis apex (lateral view) more evenly curved (figs. 22 b, c) 4

4. Shorter, elytra more convex, apex almost perpendicular in side view. Elytral striae quite regular, even laterally, intervals unbroken, at least in basal 2/3, and never granulate. Penis stouter, more curved (fig. 22 c). L. 12—14 mm. E coast-land from N.Y. to Virg. (erroneously recorded from Queb., Ont. and Manit., Beaulne, 1914, p. 155) S. stenostomus Web.
- Elytra with apex sloping (in lateral view). Striae irregular, at least laterally and in
apical half, intervals broken up into tubercles and granulae. Penis, fig. 22 b
2. S. lecontei

Is S. lecontei still a valid species?
