5A4987D6FFC90A6E64F8FE7AC600F902.taxon	diagnosis	Diagnosis. This new species is similar to Dactylotula kinkerella and D. altithermella in both forewing and the male and female genitalia, but can be distinguished by the following characters. In the new species, terminal half of the valva in the male genitalia is elliptic, densely covered with coarse setae, uncus is bilobed and saccus is rounded distally (Figs 6 – 9); in the female genitalia, a concavity is present at the middle of the dorsal margin of the papilla analis, posterior apophysis is about 1.5 times as long as the anterior apophysis, and the signum is absent (Figs 10 – 11). However, in the male genitalia, in D. kinkerella, the distal part of the valva is broad and waterdrop-shaped with short thick protuberances distributed in bands except for the normal setae on median part (Nel & Varenne 2012: figs 4, 8; Elsner et al. 1999: Pl. 2); in D. altithermella, the uncus is claw-shaped at the end (Elsner et al. 1999: Pl. 2). In the female genitalia, in D. kinkerella, papilla analis is slightly rectangular in shape; in D. altithermella, a protuberance is present at the basodorsal corner of the papilla analis; in D. kinkerella and D. altithermella, the anterior and posterior apophysis are equal in length, and both have a pair of signa (Elsner et al. 1999: Pl. 42).	en	Yang, Huiduo, Teng, Kaijian, Liu, Tengteng (2023): A new species and new record of the leaf-mining genus Dactylotula Cockerell (Lepidoptera: Gelechiidae) from China.

5A4987D6FFC90A6E64F8FE7AC600F902.taxon	biology_ecology	Biology (Figs 12 – 24). The mine of the new species is located on the upperside of the leaf, mostly near its base. The larva mines into the upper epidermis as soon as hatched (Fig. 13). The initial linear mine of the first instar larva extends along the leaf veins, then gradually becomes wider, 1.0 ~ 1.5 cm in length. The mine of the second instar larva has the width of three leaf veins, then continues to widen, after about 1.0 cm widens significantly to the width of 13 leaf veins, with a total length of about 1.5 cm (Fig. 12). The mine of the third instar larva is slightly wider than the end of the mine of the second instar larva. It is impossible to determine the normal length of the mine of the third instar and the number of instars, due to parasitic influences and limitations of the mine specimens. Mature larva pupates in the distal part of the mine (Fig. 17). During pupation, the frass in the mine are used to wrap the pupa. In the linear mine, the frass filled the entire mine but accumulated on the lateral side in the later stage (Fig. 16). The dry mine is yellow-brown with dark brown margins. It can be easily found from both sides of the leaf (Fig. 17). There are often one to three mines on a single leaf, sometimes as many as five (Fig. 16). Mines of different instars can be overlapped in late July and early August. Larvae are often parasitized by parasitoid wasps, presumably one or two species of the family Pteromalidae. The parasitized larva was unable to pupate. Two larval epicrania of different instars and one dry larval body killed by parasitoid were observed in a single mine (Fig. 15). The epicranium of this dry larval body is located at the end of the mine. It is presumed that the larva was parasitized at the third instar and then died (Fig. 14). Three to ten individuals of the parasitoid wasp in a single mine were observed (Figs 21, 22) (two mines examined). The parasitoid wasps’ emergence holes could be observed on both surfaces of the mine (Figs 19, 20). Pupal exuviae of the wasp and the adult that failed to emerge were left inside the mine (Figs 23, 24). Host plant. Phragmites australis (Cav.) Steud. (Poaceae) (Fig. 18).	en	Yang, Huiduo, Teng, Kaijian, Liu, Tengteng (2023): A new species and new record of the leaf-mining genus Dactylotula Cockerell (Lepidoptera: Gelechiidae) from China.
