A review of the Argyrogrammana fauna of the Transandean region (Lepidoptera: Riodinidae: Symmachiini)

Abstract

The Argyrogrammana Strand, 1932, fauna (Riodinidae: Symmachiini) of the Transandean region is reviewed. Thirteen species are reported from this region, including four new species that are described here from Costa Rica, Panama, and Ecuador: A. smalli Hall, n. sp. (barine group), A. vespertina Hall & Willmott, n. sp., A. janzeni Hall, n. sp., and A. cana Hall & Willmott, n. sp. (all occidentalis group). An additional extralimital occidentalis group species, A. eura Hall, n. sp., is described from the Guianas. Three names are elevated to the rank of species: A. holosticta (Godman & Salvin, 1878) from a subspecies of A. stilbe (Godart, [1824]) (rev. stat.), A. juanita (Staudinger, 1887) from synonymy with A. occidentalis (Godman & Salvin, 1886) (rev. stat.), and A. phyton (Stichel, 1911) from a subspecies of A. physis (Stichel, 1911) (n. stat.). Three names are synonymized: A. leptographia magdalenae Constantino et al., 2012, with A. leptographia (Stichel, 1911), A. iracyi P. & J. Jauffret, 2007, with A. sublimis Brévignon & Gallard, 1995, and A. saulensis tunari Gallard, 2008, with A. saulensis Gallard, 2008 (n. syn.). Lectotypes are designated for the names Argyrogramma trochilia leptographia, Charis perone Westwood, 1851, Lemonias juanita, and Charis occidentalis.
