Anogdus rileyi Peck and Cook , new species

( Fig. 27, 28 , 36 )

Diagnostic description. Length (pronotum + elytra) = 1.80–2.56 mm; greatest width = 1.20–1.60 mm. Head punctation fine and sparse on front, becoming coarser and more dense on vertex. Antennal club slender; antennomere 7 narrower than 9 and 10; antennomere 8 narrow, disk-like; apical antennomere narrower than 9 and 10. Sides of pronotum rounded, posterior angles broadly obtuse. Pronotal punctures fine, separated by 1–3 diameters. Elytral strial punctures round and deep, separated by ± 1 diameter; interstrial punctures minute, distantly spaced; elytral epipleura inconspicuously setose. Metasternal anterior margin with a row of moderately small, round, deep punctures; sides of metasternum rugose. Protarsi and mesotarsi of male broadly expanded and bearing white setae. Male mesotibia curved, inner margin weakly sinuate; mesotibial process triangular, curved, apex passing behind large tibial spine. Metafemur slender; in males the lower margin may be serrate with a broad expansion before apex with a small, acute tip. Abdominal sternites III–VII each with a row of closely spaced, round, deep punctures of about equal size at anterior margin. Median lobe of aedeagus ( Fig. 27, 28 ) elongate, broad, curved dorsoventrally, flattened toward apex. Parameres slender, apically expanded, extending beyond apex of median lobe. Armature of internal sac as in Fig. 27, 28 .

Distribution. Known only in the United States in the southern state of Texas ( Fig. 36 ).

Seasonality. Adult records are scattered through most of the year, but mostly from the cooler winter months. Almost all specimens were taken in flight intercept traps.

Bionomics. The dominant habitat is upland deciduous forest and open juniper scrub. Etymology. This species is named in recognition of Edward G. Riley, Associate Curator of Texas A & M University Insect Collection, who collected almost all of the known specimens of this species.
