03BACD5D4474474CFF34FA1ADBE5FEBC.taxon	diagnosis	Diagnosis. Macrobathra can be identified by the following characters: second segment of the labial palpi shorter than third segment; scape of the antenna elongated; forewing veins R 4 and R 5 stalked; hindwing veins M 3 and CuA 1 stalked; brachia of uncus of male genitalia usually symmetric, rarely asymmetric; valva of male genitalia usually setose distally; accessory bursae arising from ductus bursae usually present in female genitalia; pair of signa present in the corpus bursae usually equal in size (Meyrick 1886; Zhang & Li 2023). According to Zhang & Li (2023), Macrobathra is similar to Pancalia Stephens, 1829 because they share some characters, such as the labial palpi configuration, the venation on both fore- and hindwings, and the aedeagus separated from the anellus. The two genera can be distinguished by the following characters: metallic stripes on the forewing are usually presented in Macrobathra but absent in Pancalia; the aedeagus of the former is usually straight and slender whereas that of the latter is often strongly bent and stout.	en	Lu, Yi-Yang, Liang, Jia-Yuan, Hsu, Yu-Feng (2026): First records of the genus Macrobathra Meyrick, 1883 (Lepidoptera: Cosmopterigidae) from Taiwan, with description of a new species and two newly recorded species.

03BACD5D4472474CFF34FE0CDDE0F823.taxon	diagnosis	Diagnosis. This species can be distinguished by the following characters: in appearance, its forewing has no additional patterns except for the median fascia and the median fascia is slightly contracted toward dorsum; in the male genitalia, it can be quickly identified by its slender brachia of the uncus, the large anellus without any process, and the club-shaped right valva; in the female genitalia, a pair of curved horn-shaped signa combined with a cestum present in the posterior part of the ductus bursae are two characters that can be easily distinguished from other species.	en	Lu, Yi-Yang, Liang, Jia-Yuan, Hsu, Yu-Feng (2026): First records of the genus Macrobathra Meyrick, 1883 (Lepidoptera: Cosmopterigidae) from Taiwan, with description of a new species and two newly recorded species.

03BACD5D44704743FF34FC12DD4BFEB4.taxon	diagnosis	Diagnosis. The wing pattern of the new species is similar to that of M. terniprocessa Li, 2023, but they can be distinguished by the shape of the yellow fascia of M. basilutea sp. nov. nearly rectangular whereas that of M. terniprocessa trapezoidal, and the proportion of yellow fascia on the entire forewing of M. basilutea sp. nov. just over half while that of M. terniprocessa about 1 / 3. In the male genitalia, this new species can be easily identified by its distinctly minute valvae and the triangular process of the anellus. In the female genitalia, it can be recognized by its ridge-like signa.	en	Lu, Yi-Yang, Liang, Jia-Yuan, Hsu, Yu-Feng (2026): First records of the genus Macrobathra Meyrick, 1883 (Lepidoptera: Cosmopterigidae) from Taiwan, with description of a new species and two newly recorded species.
