Anogdus capitatus LeConte, 1866

( Fig. 1, 2 , 33 )

Anogdus capitatus LeConte, 1866: 369 ; Horn 1880: 283; Brown 1937b: 170; Daffner1988: 274. Holotype female in MCZC, type number 3170, designated by Daffner 1988: 274; seen by us. Type locality: USA: FLORIDA (no additional locality data).

Diagnosis. Length (pronotum + elytra) = 2.64–3.00 mm; greatest width = 1.88–2.04 mm. Head strongly, densely punctate. Antennal club distinctly robust, greatest width of club more than one-half its length; antennomere 7 broad, at least five-sixths width of 9; antennomere 8 narrow, disk-like; api- cal antennomere shorter and narrower than 9 and 10. Sides of pronotum and posterior angles broadly rounded. Pronotum minutely, sparsely punctate. Elytral strial punctures round and deep, separated by one diameter or less; interstrial punctures fine, joined by transverse strigae. Elytral epipleura with pale setae. Metasternum anteriorly with a row of deep, round punctures with diameter about equal to that of shallow punctures at sides of metasternum. Protarsi and mesotarsi of male with elongate setae ventrally. In both sexes, outer protibial spine distinctly wider than inner spine. Male mesotibia curved, widened apically; mesotibial process slender, 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 not always clearly visible in mounted specimens. Median lobe of aedeagus elongate, broad, apical one-third somewhat flattened dorsoventrally ( Fig. 1, 2 ). Parameres slender, reaching almost to apex of median lobe. Armature of internal sac as in Fig. 1, 2 .

Distribution. Known only from the southeastern states of Florida and Georgia ( Fig. 33 ). Previously published distributional data: Florida (no additional data).

New material examined (n=4). USA: FLORIDA: Walton Co.: 6.5miW US –90 & Rt. 187, 29.I.1993, P. Skelley, M. Thomas, R. Turnbow (1, FSCA) ; GEORGIA: Tattnall Co.: Reidsville, Gordonia-Altamaha State Park , 10.XI.1983, W. Steiner, A. Gerberich, J.E. Lowry (3, USNM) .

Seasonality. Adults are known only from the months of November and January, suggesting that the species is active in the cooler months.

Bionomics. We assume that the species inhabits warm temperate forest habitats.
