Lionothus ulkei Brown, 1937

( Fig. 7 , 20 )

Lionothus ulkei Brown, 1937b: 171 ; Daffner 1988: 290. Holotype, male, in CNCI, seen. Type locality:

DC [District of Columbia.]

Diagnosis. Length (pronotum + elytra) = 1.50–2.00 mm; greatest width = 1.10–1.60 mm. Reddish brown, shiny. Head punctures fine anteriorly, coarser and denser posteriorly and laterally. Head with antennal grooves ventrally. Mandibles short, forming semicircle when closed; minute tooth near middle of left mandible. Antennal club slender; antennomere 8 disc-like, nearly as wide as apex of 7; apical antennomere longer than and nearly as wide as 10. Eyes of normal size. Pronotum broad, weakly rounded laterally, posterior angles obtuse, basal margin strongly rounded. Pronotum finely punctate. Elytral strial punctures deep, separated by ±1 diameter. Interstrial punctures minute and sparse. Metasternum with fine punctures medially; coarse, unevenly spaced punctures laterally. Male mesofemur with acute toothlike expansion at apex of inner margin. Male mesotibia sinuate on inner margin. Abdominal sternites III–VII each with basal transverse row of large punctures. Median lobe of aedeagus ( Fig. 7 ) cylindrical, strongly curved dorsoventrally at basal one-third; in lateral view, evenly dorsoventrally flattened in apical one-fourth; paired apices moderately broad. Parameres narrow, not reaching apex of median lobe. Internal sac as in Fig. 7 .

Distribution. North American distribution ( Fig. 20 ): UNITED STATES. DISTRICT OF COLUMBIA, FLORIDA, GEORGIA, MARYLAND, MISSISSIPPI, OKLAHOMA, TEXAS, VIRGINIA.

Previously recorded in North America ( Brown 1937b, Daffner 1988) from: UNITED STATES. DISTRICT OF COLUMBIA. FLORIDA. Dade Co., Chekika State Recreation Area, 50 km SW Miami. Deering Estate Park, S. Miami. Long Pine Key, Everglades National Park. Monroe Co., 1.5 km NW Royal Palm and Royal Palm Hammock. OKLAHOMA. Latimer Co., Red Oak. VIRGINIA. Luray, Shenandoah National Park.

Daffner (1988) includes a single specimen record from Arizona: Santa Cruz Co., Patagonia, Sonoita Creek Sanctuary. We have not seen this specimen to confirm the identity and have not included the record on our map.

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

Bionomics. Adults have been collected in various forest types ranging from cypress swamp, subtropical hammock, pinelands, oak-palm hammock, bottomland forest, redbay-live oak forest, and post oak savannah, mostly on sandy soils, They have been taken mostly by flight intercept traps but some from malaise and black light traps.
