Adults of Thiotricha spp. A , T. subocellea (Stephens) , ♂; B, T. apicispinea sp. nov. , ♂, holotype; C, T. fasciaria sp. nov. , ♂, holotype; D, T. atralata sp. nov. , ♂, holotype; E, T. lativalva sp. nov. , ♂, holotype; F, T. gracilis sp. nov. , ♂, holotype; G, T. vittata sp. nov. , ♂, holotype; H, T. minuta sp. nov. , ♂, holotype. Diagnosis. Adult ( Fig. 6A ). Wingspan 9.0− 14.5 mm . Thiotricha subocellea closely resembles T. apicispinea in superficial appearance, but the forewing is slightly broader and the markings are more vivid in the former. In the male genitalia ( Figs 5B , 69A ), the asymmetrical valvae with a digitate process on the right valva are similar to those of T. apicispinea and T. fasciaria . However, distal 1/3 of the valva is spatulate in T. subocellea whereas those are sharply narrowed in two other species. Biology. The larva is concealed in a portable case and feeds on the seeds of the host plants from August to late October ( Bland et al . 2002 ). Agathis fuscipennis (Zetterstedt) ( Hymenoptera ) has been reported as a parasitoid of the species in Europe ( Loni et al . 2011 ). Host plants. Lamiaceae : Calamintha sp. , Mentha aquatica L., Origanum vulgare L., Satureja montana L., Thymus polytrichus A. Kern. ex Borbás and T. vulgaris L. ( Bland et al . 2002 ; Sakamaki 2013 ). Distribution. China ( Anhui , Gansu , Hebei , Jilin , Ningxia , Shanxi ), Korea , Japan , Russia (all regions), Europe. Remarks. Thiotricha subocellea is one of the best well-known species in the genus and is widely distributed in the Palaearctic Region. Descriptions for adults and genitalia are provided by Huemer (1993) and Bland et al . (2002) , and a detailed history of synonymy is given in Huemer (1993) .
