Phyllophaga (Phyllophaga) sericata ( Erichson, 1848)

Ancylonycha sericata Erichson 1848: 563 ( Guyana)

Distribution. Guyana: Erichson 1848: 563 (as Ancylonycha sericata ). French Guiana: Blackwelder 1944: 225 (treated as a synonym of P. leprieuri ( Blanchard, 1851)) ; Evans and Smith 2009: 130. Other: Dalla Torre 1912: 194 (none - treated (as Lachnosterna sericata ) as a possible synonym of P. leprieuri ( Blanchard, 1851) (as L. leprieuri )); Frey 1975 (not mentioned).

Note 1. Blackwelder (1944: 225) considers Phyllophaga sericata ( Erichson, 1848) (p. 563) as a synonym of P. leprieuri ( Blanchard, 1851) (p. 134), but according to Evans and Smith (2009: 130) these are separate species.

Note 2. Ancylonycha sericata Blanchard, 1851 (p. 136) is a junior homonym of Phyllophaga sericata ( Erichson, 1848) and has been given the replacement name P. yucana Saylor, 1937 (p. 321). Phyllophaga yucana is a species from Venezuela and Colombia and has not been recorded for the research area.

Note 3. Phyllophaga sericata is described as Ancylonycha sericata in Erichson (1848: 563) . This entire publication is dedicated to the biodiversity of present-day Guyana, and it is unclear to us why subsequent authors ( Blackwelder 1944: 225; Evans and Smith 2009: 130) mention the species only for French Guiana. Because of the clarity of the location in the describing publication, we are hesitant to blame this anomaly on a misinterpretation of the data. For now, we regard this species as recorded from Guyana as well as French Guiana.
