AE10F518C90B4B05FF71F8E4FD3E5CD7.taxon	discussion	Remarks. Five syntypes were examined, provided with detailed data of three in this study. Among them, one female with same data as lectoparatype was mismatched with the male according to our present study. Two additional examined specimens collected in Malaysia are confirmed to be misidentified as E. ancylopa Meyrick. They belong to a different species, which needs to be further studied. This species is newly recorded for China.	en	Li, Houhun, Zhang, Zhenguo (2016): Five species of the genus Epicephala Meyrick, 1880 (Lepidoptera: Gracillariidae) from China.

AE10F518C9024B06FF71FDF6FDA15837.taxon	diagnosis	Diagnosis. Epicephala duoplantaria sp. nov. is more similar to E. ancylopa Meyrick, 1918 in appearance, but can be distinguished from the latter in the male genitalia by the costa arched medially, the sacculus acute apically, the broad saccus parallel to rounded apex, and the cornutus with a spiniform spine of varying length distally; and in the female genitalia by the lamella postvaginalis shallowly and widely concave on the posterior margin, and the antrum about 1 / 4 the length of the ductus bursae. In E. ancylopa Meyrick, the costa is straight, the sacculus is blunt at apex, the clubbed saccus is narrowed to rounded apex distally, and the cornutus is absent of the apical spiniform spine in the male genitalia; and the lamella postvaginalis is deeply concave in broad V shape or U shape on the posterior margin, and the antrum is about 1 / 3 the length of the ductus bursae in the female genitalia. Epicephala duoplantaria sp. nov. can also be separated from E. daltonii sp. nov., E. jianfenglingina sp. nov. and E. assamica sp. nov. by having a saccus about half width of the sacculus and the cornutus being a wrinkled elongate plate bearing an apical thorn in the male genitalia, and the suboval lamella postvaginalis (Fig. 17). In E. daltonii sp. nov., the narrower saccus is less than 1 / 5 width of the sacculus and the cornutus is an elongate ovate plate bearing numerous denticles, and the torch-like lamella postvaginalis posterolaterally produced to triangular process with sharply pointed apex (Fig. 18); in E. jianfenglingina sp. nov., the saccus is slightly less than half width of the sacculus and the cornutus consists of a row of clustered long spines (Fig. 9 b), and the H-shaped lamella postvaginalis posterolaterally produced to a triangular process with narrowly pointed apex (Fig. 19); in E. assamica sp. nov., the broad saccus is about 4 / 5 width of the sacculus and the cornutus consists of a row of clustered short spines (Fig. 10 d), and the inverted trapezoidal lamella postvaginalis posterolaterally produced to a long thorn-like process with sharp apex (Figs. 15 a, 15 b).	en	Li, Houhun, Zhang, Zhenguo (2016): Five species of the genus Epicephala Meyrick, 1880 (Lepidoptera: Gracillariidae) from China.

AE10F518C9004B00FF71F9C6FB86587F.taxon	diagnosis	Diagnosis. This new species is similar to E. duoplantaria sp. nov. in appearance. It can be further separated from the latter in the male genitalia by the phallus subovately dilated basally; in the female genitalia by the lamella postvaginalis with lateral margins subparallel and posterior margin deeply concave in broad V shape. In E. duoplantaria sp. nov., the phallus is slightly expanded basally in the male genitalia; the lamella postvaginalis is arched laterally and shallowly concave on the posterior margin in the female genitalia.	en	Li, Houhun, Zhang, Zhenguo (2016): Five species of the genus Epicephala Meyrick, 1880 (Lepidoptera: Gracillariidae) from China.

AE10F518C9074B01FF71FA1EFF7B5B57.taxon	diagnosis	Diagnosis. Epicephala assamica sp. nov. is similar to E. frenata Meyrick, 1908 in appearance and male genitalia. It can be separated from the latter in the male genitalia by the sacculus narrower than 1.5 times of costal part at maximum width, and the phallus with two denticles at apex. In E. frenata Meyrick, the sacculus is wider than 2 times of costal part at maximum width, and the phallus has a small apical thorn in the male genitalia. Epicephala assamica sp. nov. is also similar to E. ancylopa, and the differences between them can be found under E. ancylopa Meyrick.	en	Li, Houhun, Zhang, Zhenguo (2016): Five species of the genus Epicephala Meyrick, 1880 (Lepidoptera: Gracillariidae) from China.
