Anogdus huachuca Peck and Cook , new species

( Fig. 25, 26 , 34 )

Diagnostic description. Length (pronotum + elytra) = 1.58–1.88 mm; greatest width = 1.02–1.20 mm. Head punctures of moderate size, irregularly spaced. Antennal club slender; antennomere 7 narrower than 9 and 10; antennomere 8 disk-like, narrow; apical antennomere slightly narrower than 9 and 10. Sides of pronotum weakly rounded, posterior angles obtuse. Pronotal punctures minute and distantly spaced. Elytral strial punctures longer than wide, deep, mainly separated by less than 1 diameter; interstrial punctures minute, distantly spaced; elytral epipleura inconspicuously setose. Metasternal anterior margin with a row of large, deep punctures; remainder of metasternum with smaller shallow punctures. Protarsi and mesotarsi of male bearing white setae ventrally. Male mesotibia slender, curved; mesotibial process broad at base, narrowing to acute apex, shorter than large tibial spine. Metafemur slender, males with a broad, triangular expansion near the apex of the lower margin. Abdominal ster- nite III with a row of small, deep punctures at anterior margin. Sternites IV–VII also with punctures at anterior margin that are usually not visible in dry specimens. Median lobe of aedeagus ( Fig. 25, 26 ) elongate, cylindrical, evenly curved dorsoventrally, with rounded apex. Parameres slender, not widened apically, nearly reaching apex of median lobe. Inverted internal sac as in Fig. 25, 26 .
