Anogdus LeConte, 1866

Anogdus LeConte 1866: 369 . Type species: Anogdus capitatus LeConte, 1866 ; by monotypy. Brown 1937b: 170. Daffner 1988: 271.

Neocyryusa Brown 1937a: 161. Type species: Pallodes obsoletus Melsheimer, 1844 ; by original designa- tion. Synonymy by Daffner 1988: 271.

Diagnosis. Body convex, oval to elongate-oval. Antennae with 11 antennomeres, with a club composed of 5-antennomeres, and the club interrupted at the 8 th antennomere, which is narrow and disk shaped. Left mandible with a large and sharp tooth in the middle, right mandible with a small tooth in the middle. Ventral side of head without antennal grooves. Mesosternum vertical between the mesocoxae and with a distinct median longitudinal carina. Protibiae with tarsal grooves, their outer margins with strong spines; mesotibiae with a dense double row of spines; the outer margin of the metatibiae with short, strong spines. Tarsal formula 5-5- 4 in both sexes. Males are distinguished externally by weakly expanded protarsi and moderately expanded mesotarsi, slightly curved mesotibiae bearing a stout process on the inner apical margin, and by a toothlike expansion near the apex of the lower margin of the metafemur.

Variation. The following external characters of Anogdus are variable within species: size and density of punctation, width of antennomeres, pronotal shape, and sexually dimorphic leg characters. Iden- tifications must be based on aedeagal characters. Females of most species can be identified only by association with males.

Remarks. The genus Anogdus was established chiefly because of the stated “10-segmented” antennae. However, Daffner (1988) found the type species to have antennae with 11 antennomeres, and an an- tennal club of 5 antennomeres, interrupted at antennomere 8, which is disk shaped and barely visible in the type species because of the other very large club antennomeres. Brown (1937a) established the genus Neocyrtusa on the basis of an antenna with 11 antennomeres and otherwise found no differences, so Daffner (1988) synonymized Neocyrtusa under Anogdus .

The genus is Nearctic in published distribution, with unpublished material known from the Neo- tropics. “ Anogdus ” trimeni Champion (1925) of South Africa is wrongly assigned to this genus ( Newton 1998: 87) and the species belongs instead to a genus in the “ Leiodes genus group” ( Peck 2003: 125) but males are needed for accurate generic placement.
