Abstract:

The taxonomic status of Phola octodecimguttata (Fabricius, 1775) and its synonyms are re-evaluated. Phyllophila sedecimpustulata Stål, 1857 as a junior synonym of Phola octodecimguttata is supported by examining their type specimens and genitalic characters in a large number of specimen. In addition, Chalcolampra dipa Maulik, 1926 n. syn. is herein synonymized with Phola octodecimguttata. Phola decempustulata (Baly, 1864) n. comb., transferred from Chalcolampra, is examined and redescribed. New data on the biology of P. octodecimguttata are provided. Its association with the coastal plant Vitex rotundifolia helps explain its occurrence on many small islands.
