Anogdus dissimilis Blatchley, 1916

( Fig. 3, 4 , 33 )

Anogdus dissimilis Blatchley, 1916: 93 ; Brown 1937b: 170; Daffner 1988: 274. Holotype male in Purdue University (PURC), designated by Daffner 1988: 275; type specimen not seen, not available. Type locality: USA: FLORIDA: Dunedin.

Diagnosis. Length (pronotum + elytra) = 2.00– 2.80 mm; greatest width = 1.32–1.92 mm. Head strongly, densely punctate. Antennal club distinctly robust, greatest width of club more than one-half its length; antennomere 7 narrow, less than two-thirds width of 9; antennomere 8 narrow, disk-like; apical antennomere shorter and narrower than 9 and 10. Sides of pronotum roundly angulate near middle, posterior angles roundly obtuse. Pronotal punctation variable, fine to coarse, moderately sparse to moderately dense. Elytral strial punctures round and deep, separated by ± one diameter; interstrial punctures fine to coarse, joined by transverse strigae posteriorly; elytral epipleura with pale setae. Metasternum anteriorly with a row of deep, round punctures with diameter about equal to or smaller than that of shallow punctures at sides of metasternum. Protarsi and mesotarsi of male with elongate setae ventrally. In both sexes, outer protibial spine significantly wider than inner spine. Male mesotibia and metatibia evenly widened to apex; mesotibial process slender, shorter than large mesotibial spine. Metafemur robust; males may have an acute tooth-like or simple rounded 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 robust; apex short, lobed, not flattened dorsoventrally ( Fig. 3, 4 ). Parameres slender, reaching almost to apex of median lobe. Armature of internal sac as in Fig. 3, 4 .

Distribution. Known widely in the United States from New Jersey to Illinois and Nebraska and south to New Mexico, Texas and Florida ( Fig. 33 ). Previously published distributional records in Daffner (1988: 274): USA. FLORIDA: Pinellas Co., Dunedin. ILLINOIS: no additional locality data. NEW JERSEY: Stone Harbor.

Seasonality. Adults are known mostly from the months of October through to April, suggesting that the species is active in the cooler months, especially in the southern parts of its range.

Bionomics. The records are usually from scrubby or mixed forest habitats, and usually on sandy soils. Specimens were caught mostly with malaise and flight intercept traps.
