Plectris LePeletier de Saint-Fargeau & Audinet-Serville, 1828 View in CoL

Rhizonemus Dejean, 1836b: 180 View in CoL , nomen nudum.

Anomalochilus Blanchard, 1850: 123 View in CoL , syn. nov. Type species: Anomalochilus singularis Blanchard, 1850 View in CoL (designation: monotypy).

Demodema Blanchard, 1850: 121 View in CoL . Type species: Demodema fallax Blanchard, 1850 View in CoL (designation: Lacordaire 1856: 258).

Demodema View in CoL – Katovich 2008: 6 (synonymy).

Type species

Plectris tomentosa LePeletier de Saint-Fargeau & Audinet-Serville, 1828 View in CoL (designation: monotypy).

Diagnosis

Labrum deeply emarginate; pronotal anterior and posterior margins not beaded; prosternum with an anterior longitudinal carina; elytral striae indistinct, elytral posterior and posterointernal margins not beaded; metatarsomere I as long as II–IV; metatarsomere VI longer than wide; metatarsomere V with internoproximal spine-like setae ( Fig. 4 A View Fig ).

Remarks

See Anomonyx (above). Plectris is the biggest and most problematic genus of Macrodactylini . The diagnosis provided by the present study or by Katovich (2008) do not include all species, and the review of Frey (1967) did not define the genus clearly. The species richness, taxonomic problems, and

the economic importance (e.g., Roberts 1968; Brill & Abney 2013) of Plectris show the urgency for systematic works on the genus.

The present study proposes the synonymy of Anomalochilus with Plectris , and two species previously placed in Anomalochilus are transferred to Plectris : P. pilosella ( Blanchard, 1850) comb. nov. and P. singularis comb. nov.
