A new cryptic species of Nagiella Munroe from China revealed by DNA barcodes and morphological evidence (Lepidoptera Crambidae Spilomelinae)

摘要

Nagiella occultalis Misbah & Yang, >sp. n. from China is described and illustrated. This new species is very similar to N. quadrimaculalis (Kollar, 1844) in general morphological characters of forewing and male genitalia. Molecular evidence shows that these two species diverge in COI barcode region by more than 3.2%. Sequence divergence among the two species is congruent with subtle morphological differences. Wing venation and male genitalia of the two species are compared and illustrated.
