Zeadolopus bifoveolatus Daffner, 1988

( Fig. 13 , 24 )

Zeadolopus bifoveolatus Daffner, 1988: 301 . Holotype, male, in CMNC, seen. Type locality: Sugarloaf Key , Monroe County, FL.

Diagnosis. Length (pronotum + elytra) = 1.42–1.90 mm; greatest width = 1.00– 1.42 mm. Light reddish brown, shiny. Head punctures variable in size and spacing. Antennal club usually not darker than funicle; antennomere 9 longer and wider than 8; apical antennomere narrower than 9, subequal in length. Sides of pronotum rounded, posterior angles rounded; base rounded medially, concave before posterior angles. Pronotal punctation fine and widely spaced. Elytral strial punctures deep and closely spaced; clearly visible almost to base. Interstriae finely punctate. Metasternum densely punctate with coarse punctures laterally, finer punctures medially. Metatibia evenly and strongly widened, widest at apex, there 3.5 times as wide as at the base. In males, abdominal sternite III with a pair of foveae at anterior margin; foveae usually bearing white setae; sternites IV–VII each with transverse row of small setose punctures near middle. Median lobe of aedeagus ( Fig. 13 ) broad; paired apices curved, meeting apically. Parameres extend beyond apex of median lobe. Internal sac as in Fig. 13

Distribution. North America ( Fig. 24 ). UNITED STATES. FLORIDA; only in the extreme south, in Dade and Monroe counties. Previously recorded ( Daffner 1988) from: FLORIDA. Dade Co., Everglades National Park, Royal Palm Hammock. 1.5 km NW Royal Palm. S Miami, Deering Estate Park. Old Cutler Hammock. Monroe Co., Big Pine Key, Watsons Hammock. Big Torch Key. Cudjoe Key. Lignum Vitae Key. No Name Key. Sugar Loaf Key, Kitchings Hammock. Key Largo, Pennekamp State Park. Fat Deer Key. This distribution suggests that the species may also occur in Cuba or the Bahamas.

Seasonality. Adults are known from the cooler months of October to March.

Bionomics. All adults have been collected in subtropical hammock forests. They have been taken in flight intercept and malaise traps, except one in an ultraviolet light trap.

New material examined. We have seen 152 specimens. There are no new records.
