( Fig. 8 , 21 )

Lionothus forticornis Daffner 1988: 291 . Holotype, male, in Daffner collection, not seen. Type locality: Mark Twain National Forest, MO.

Diagnosis. Length (pronotum + elytra) = 1.90–2.40 mm; greatest width = 1.26–1.70 mm. Reddish brown, shiny. Head punctures fine and sparse anteriorly, coarser and more dense posteriorly and laterally. Head with antennal grooves ventrally. Mandibles short, forming semicircle when closed; small tooth at apical one-third of left mandible. Antennal club slender; antennomere 8 disc-like, narrower than apex of 7; apical antennomere about as long as and narrower than antennomere 10. Eyes of normal size. Pronotum broad, rounded laterally, posterior angles obtuse, basal margin rounded. Pronotum finely punctate; punctures sparse medially, more dense laterally. Elytral strial punctures deep, separated by ±1 diameter. Interstrial punctures minute and sparse. Metasternum finely punctate medially; with coarse, irregularly spaced punctures laterally. Male mesofemur unmodified. Male mesotibia straight on inner margin. Abdominal sternites III–VII each with basal transverse row of large punctures. Median lobe of aedeagus ( Fig. 8 ) cylindrical, evenly curved in lateral view; paired apices short, moderately slender. Parameres narrow, not reaching apex of median lobe. Internal sac as in Fig. 8 .

Seasonality. Adults have been collected from February to October, with most in the months of June to August.

Bionomics. Adults have been collected mostly in upland and lowland mixed forests, and a few in juniper and other scrub vegetation.
