Zeadolopus rubricornis Daffner, 1988

( Fig. 15 , 24 )

Zeadolopus rubricornis Daffner, 1988: 299 . Holotype, male, in CMNC. Type locality: S. Miami, Dade County, FL.

Diagnosis. Length (pronotum + elytra) = 1.40–2.02 mm; greatest width = 1.00– 1.68 mm. Reddish brown, shiny. Head punctures moderately fine, variably spaced. Antennal club of same color as funicle; apical antennomere longer and narrower than penultimate antennomere. Sides of pronotum rounded, posterior angles rounded; base rounded medially, weakly concave before posterior angles. Pronotal punctation fine, widely spaced. Elytral strial punctures deep and closely spaced, not discernible near base. Interstriae finely, sparsely punctate. Metasternum finely, sparsely punctate medially; coarsely, irregularly punctate laterally. Metatibia widest just before apex, 3 to 4 times as wide as at base. Abdominal sternites III–VII each with transverse row of fine punctures before apex. Median lobe of aedeagus ( Fig. 15 ) broad, paired apices short and broad. Parameres broad, not extending beyond apex of median lobe. Internal sac as in Fig. 15 .

Distribution. North American distribution ( Fig. 24 ): UNITED STATES. FLORIDA; only in the extreme south in Dade and Monroe counties.

Previously recorded in North America ( Daffner 1988) from: UNITED STATES. FLORIDA. Dade Co., S Miami, Deering Estate Park. Everglades National Park, Royal Palm Hammock. Monroe Co., Big Pine Key, Watson Hammock. Cudjoe Key. Fat Deer Key. Key Largo, Pennekamp State Park. Lignum Vitae Key, near Islamorada. Sugarloaf Key, Kitchings Hammock.

Seasonality. Adults have been collected throughout the year, but mostly in the cooler months from October to February.

Bionomics. All collections are from subtropical hammock forest in extreme southern Florida. All have been taken by flight intercept and ultraviolet light traps.

New material examined. We have seen 132 specimens, including the following new localities: UNITED STATES. FLORIDA. Dade Co. Old Cutler Hammock, 7900 SW 176 th St. Everglades National Park, Long Pine Key. Monroe Co. Big Pine Key, No Name Road. Big Torch Key. Key Vaca. Middle Torch Key. No Name Key. Stock Island. Sugarloaf Key, SE ¼, Section 23. This distribution suggests that the species may also occur in Cuba or the Bahamas.
