Crambidae belonging to Pyraloidea comprise about 11,700 species in the world (Munroe and Solis, 1999). The monophyly of Crambidae is supported by multiple synapomorphies: the presence of one or two L setae on the abdominal segment IX of larvae; a praecinctorium associated with the tympanal organ; tympanal case opening anteromedially; and tympanum and conjunctivum meeting at an angle (Minet, 1982), and also molecular data (Regier et al., 2012).
The Korean species of Crambidae were first studied by Leech (1889). Since then, there have been a total of 112 genera, 266 species of Crambidae recorded from Korea (Bae et al., 2008). Given the numbers of species known from the adjacent countries, the crambid fauna of Korea has not been exhaustively inventoried and thus many new records are still predicted. In the present study, four species of Crambidae are recorded from Korea for the first time.
Material and methods
All the specimens examined are deposited in three collections: GJUE – Gongju National University of Education; MPNU – Mokpo National University; and NIBR – National Institute of Biological Resources. Terms of genitalia follow Klots (1970). The “GSN” in the collecting data indicates a genitalia slide number. Plant names came from the website ‘Plant List’ (http://www.theplantlist.org/).

Distribution. Korea (South), Japan.
Host plants. Acanthaceae – Codonacanthus pauciflorus (Nees) Nees, Dicliptera chinensis (Juss.) K. D. Koenig; Amaranthaceae – Achyranthes aspera var. rubrofusa (Wight) Hook. f.; Asteraceae – Eupatorium formosanum Hayata (Yamanaka and Sasaki, 2013).

Athaloessa; Snellen, 1880: 75. Misspelling.
ChnauraLederer, 1863: 435. Type species: Syngamia octavialisWalker, 1859.
This genus comprises three species, two of which broadly occur in the pantropical regions. Members of Aethaloessa exhibit orange-colored and brown-patterned body and wings. A common feature in the genitalia of congeners include a pair of valvae connected with each other basally, forming transverse membrane over the tegumen. Larvae of Aethaloessa are mainly leaf-rollers on Poaceae and Urticaceae (Jazen and Hallwachs, 2009;Mally et al., 2019). The genus Aethaloessa is reported for the first time from Korea.

Distribution. Korea, Japan, China, Taiwan, Southeast Asia, South Asia, Oceanic islands, Australia.
Host plants. Urticaceae – Gonostegia hirta (Blume ex Hussk.) Miq. (Yamanaka and Sasaki, 2013).
Remarks. This species includes two subspecies: A. c. calidalis from India and Sri Lanka and A. c. tiphalis from Malaya to Australia. These subspecies differ in the length of the main cornutus in the phallus (shorter in A. c. calidalis) and the length of the corpus bursae in the female genitalia (longer in A. c. calidalis). The specimens collected from Korea belong to the subspecies tiphalis. The collecting dapta from Korea indicate that A. calidalis is a rare migrant.

Host plants. Unknown.
Remarks. This species comprises two subspecies: A. s. subfumalis from Taiwan and A. s. continentalis Munroe et Mutuura from China (Munroe and Mutuura, 1971). The smaller wing expanse and the paler hindwing of the Korean specimens of A. subfumalis suggest that they belong to the subspecies continentalis, but examination of male specimens is needed to confirm the subspecific status.
