TL;DR: Caterpillars of Siderone marthesia nemesis have been found on Casearia sylvestris Sw.
Abstract: Caterpillars of Siderone marthesia nemesis (Illiger, 1802) (Nymphalidae, Charaxinae) have been found on Casearia sylvestris Sw. (Flacourtiaceae), during the second half of the rainy season in an area of cerrado near Brasilia, Distrito Federal, Brazil. They occurred at very low density and are cryptic at all instars. The pupal stage does not occur on the host plant. Average duration of the pupa under laboratory conditions is 14.4 days.
TL;DR: This work describes a new species, Zaretis pythagoras n.
Abstract: We review the taxonomy of the genus Zaretis Hubner, [1819], restoring Zaretis isidora Cramer to specific status ( stat. rev. ) and describing a new species, Zaretis pythagoras n. sp., from the Choco region of western Colombia and western Ecuador. We also provide a key to identification of adult Zaretis and a synonymic checklist of all described names.
