03CEED77A77ADA18FD80FCB1FEF1FBFF.taxon	diagnosis	Diagnosis The new species can be distinguished from other known species of the group by the roundly arched outward lateral arms of the gnathos far exceeding the anterior margin of the tegumen, the ventral margin of the costal part of the valva which is produced triangularly dorsad before the apex, and the elongated saccus twice as long as the uncus. The new species is similar to M. oxygona sp. nov. in the male genitalia, and can be distinguished from it by the costal part of the valva lacking a cluster of tiny processes before the apex, and the sacculus lacking a long digitiform process dorso-apically. In M. oxygona, the costal part of the valva has a cluster of tiny processes before the apex, and the sacculus is produced to a long digitiform process dorso-apically.	en	Zhu, Xiaoju, Wang, Shuxia (2025): Five new species of the genus Meleonoma Meyrick, 1914 (Lepidoptera: Autostichidae) from China.

03CEED77A772DA10FDB7FEF0FEF1FDE7.taxon	diagnosis	Diagnosis The new species is similar to M. acuminata sp. nov. in the male genitalia by the costal part of the valva ending with a spine. Meleonoma oxygona sp. nov. can be distinguished from M. acuminata by the presence of the following characteristics in the male genitalia: the costal part of the valva is with a cluster of tiny processes before the apex, and the sacculus produced to a long digitiform process dorso-apically. In M. acuminata, the costal part of the valva lacks a cluster of tiny processes before the apex, and the sacculus lacks a long digitiform process dorso-apically.	en	Zhu, Xiaoju, Wang, Shuxia (2025): Five new species of the genus Meleonoma Meyrick, 1914 (Lepidoptera: Autostichidae) from China.

03CEED77A771DA11FD87FDA0FEF4FBB5.taxon	diagnosis	Diagnosis The new species is similar to M. taeniophylla Wang & Zhu, 2020 in both the forewing pattern and male genitalia. The new species can be distinguished from M. taeniophylla in the male genitalia by the following characters: i) the costal part of the valva with a small denticle above the ventral angle, ii) the sacculus produced to a small digitiform process dorso-apically, and iii) the strong saccus shorter than the slender uncus. In M. taeniophylla, the costal part of the valva lacks a denticle above the ventral angle, the sacculus lacks a small dorso-apical process and the saccus is as long as the uncus (Wang & Zhu 2020: 277, fig. 42).	en	Zhu, Xiaoju, Wang, Shuxia (2025): Five new species of the genus Meleonoma Meyrick, 1914 (Lepidoptera: Autostichidae) from China.
