Two new species of the Plutodes costatus-group from the Philippines and Indonesia (Lepidoptera, Geometridae, Ennominae)

摘要

Two new species, Plutodes magdelinae sp. n. from Mindanao Island, the Philippines, and P. thorbeni sp. n. from Sulawesi, Indonesia, are described. Pattern and coloration clearly indicate that they are members of the P. costa-te-group. Besides the well-known, wide-spread and often abundant P. costatus Butler, 1886, other members of this species-group are P. warreni Prout, 1923, and P. moultoni Prout, 1923. The latter species, described from Peninsular Malaysia, is redescribed. It is very similar externally to P. magdelinae sp. n., but clearly different in the genitalia morphology. Its known range of distribution is fairly extended, based on new records. P. hermanowskii Stiining, 2005 (Luzon, Philippines) is the most recently described species in thisgroup. DNA barcoding of all involved taxa revealed that they are well differentiated also on the genetic level.
