Description

Petala margaritacea (Terada, 2016)

Figs 1 G, 1 H, 3 F, 4 E, 5 B, 7

Pachyrhabda margaritacea Terada, 2016: 115. TL: Kyushu, Japan. TD: OMU.

Petala margaritacea: Shen et al. 2024: 20.

Korean name.

Byeol-go-sa-ri-kkok-ji-na-bang.

Material examined.

Korea • 6 ♂ 4 ♀; Jeju-do, Jeju-si, Yeon-dong; 24. VIII. 2020 – 24. VI. 2024; Ga-Eun Lee leg.; genitalia slide nos LGE 20014 m, LGE 20015 f, LGE 24022 m; DNA voucher nos LGE-G 551, LGE-G 894 • 1 ♂; Jeju-do, Jeju-si, Hallim-eup, Gwideok-ri; 12. VII. 2022; Ga-Eun Lee leg.; genitalia slide no. LGE 20018; DNA voucher no. LGE-G 896 • 1 ♀; Jeju-do, Jeju-si, Hallim-eup, Dongmyeong-ri; 22. VI. 2023; Ga-Eun Lee leg.; genitalia slide no. LGE 24020; DNA voucher no. LGE-G 898 (all deposited in JNU except for one male in NIBR).

Diagnosis.

Forewing span 6.5–7.5 mm (n = 12). Petala margaritacea is closely related to P. aedificatrix and the differential diagnosis between the two species is stated under the latter.

Host plant.

Thelypteridaceae: Christella acuminata (Houtt.) Holttum (Terada 2016).

Biology.

Larvae make silky galleries on the underside of fern fronds as in P. aedificatrix. Adults have been collected from April to October in Japan (Terada 2016).

Distribution.

(Fig. 7) Korea (new record), Japan.

Remarks.

Detailed descriptions of the adult and genitalia are provided in Terada (2016). The host plant has been referred to as Thelypteris acuminata (Houtt.) Morton in Japan (Terada 2016) and as Cyclosorus acuminatus (Houtt.) Nakai in Korea (National Institute of Biological Resources 2025). Here, we adopt Christella acuminata (Houtt.) Holttum following recent global taxonomic treatments (WFO 2026).
