Anogdus alachua Peck and Cook , new species

( Fig. 21, 22 , 35 )

Diagnostic description. Length (pronotum + elytra) = 2.08–2.76 mm; greatest width = 1.44–1.96 mm. Head moderately strongly, irregularly punctate. Antennal club distinctly robust, greatest width of club more than one-half its length; antennomere 7 narrow, about two-thirds width of 9; antennomere 8 narrow, disk-like; apical antennomere shorter and narrower than 9 and 10. Sides of pronotum weakly angled near middle; pronotum widest at obtuse posterior angles. Pronotum minutely, sparsely punctate. Elytral strial punctures round and deep, separated by one diameter or less; interstrial punctures fine, joined by transverse strigae posteriorly. Elytral epipleura with short pale setae. Metasternum anteriorly with a row of deep, round, irregularly separated punctures with diameters about equal to the shallow punctures at sides of metasternum. Protarsi and mesotarsi of male with elongate setae ventrally. In both sexes, outer protibial spine wider than inner spine. Male mesotibia variably curved, narrower than in A. dissimilis ; mesotibial process variable in shape, shorter than large mesotibial spine. Metatibia and metafemur more slender than in A. dissimilis . Male metafemur with small, acute tooth-like expansion near the apex of the lower margin. Abdominal sternites III–VII with a row of small, deep punctures at anterior margin; these punctures are not always clearly visible in mounted specimens. Median lobe of aedeagus more slender than in A. dissimilis ; apex elongate, flattened dorsoventrally ( Fig. 21, 22 ). Parameres slender, reaching almost to apex of median lobe. Armature of internal sac as in Fig. 21, 22 .

Type material (n=29). Holotype, male in FSCA, with following label data: FLORIDA: Alachua Co. / 29°34½’N, 82°29’W / 7.III.1995 // Randall W. Lundgren / flight-barrier trap / in hardwood hammock . Paratypes (28), same data as holotype (22, FSCA; 6, SBPC) .

Distribution. Known only from the United States in the southeastern state of Florida ( Fig. 35 ).

Seasonality. Adults are known only from the month of March.

Bionomics. The only known habitat is live oak hammock on sand soil, taken with flight intercept traps.
