(19) Nemophora issikii Kozlov & Hirowatari, 1997

(Plate X-1)

Nemophora issikii Kozlov & Hirowatari, 1997, Ent. Scand., 28: 95, figs. 5, 7 (TL: China, Taiwan, Sinsuiei [Chinshuiying]; USNM); Shao et al. 2008: 550 (Checklist of Taiwan).

Diagnosis. This species differs from N. aritai and N. marisella by the oblique central fascia of the forewing. and differs from N. honeella by the pale ochreous base of the forewing and relatively larger size.

Specimen examined. Holotype ♀ in USNM.

Distribution. China (Taiwan).

Remarks. Although this species was described based on a single female adult, the special structure of the female antenna is sufficient to make it as an independent species. The base of the female antenna is thickened by covering scales in many Nemophora species, but this character is well developed in this species, which is similar to N. maxinae from Thailand and Myanmar (Kozlov & Robinson 1996b). However, the latter species has no forewing central fascia and is thus distantly related to N. issikii (Kozlov & Hirowatari 1997) .
