Imma lathidora Meyrick, 1914

Imma lathidora Meyrick, 1914: 56 ; Diakonoff, 1967: 298, figs. 813, 824.

Material examined. 1 male, 19. V. 2018, Mt. Nankun , Longmen County, Huizhou City, Guangdong Province, P. R. China, leg. Si-yao Huang ( SCAU) .

Diagnosis. Imma lathidora can be distinguished from other congeners by the totally black forewing and hindwing without any markings. The male genitalia of I. lathidora are characterized by the slender and ventrally sinuate distal process of the sacculus, while in other species of Imma this process is usually stout and straight.

Remarks. After being described by Meyrick (1914), this species has not been reported elsewhere nor discovered for the second time, even in Taiwan, the collecting location of the holotype. Diakonoff (1967) examined the unique holotype of I. lathidora and figured it together with its genitalia in his work. By comparing the figure of genitalia in Diakonoff (1967) and the individual from Mts. Nankun, we only found small differences between them, which can be explained by individual or geographic variation. Thus, Imma lathidora ( Meyrick, 1914) is here rediscovered, 105 years after the description, and reported from mainland China for the first time.

Distribution. China (Guangdong *, Taiwan).
