Description. Adult (Figs 2–3, 5, 18) wingspan 16.0–24.0 mm.
Female genitalia (Figs 40–43). Apophyses posteriores about 6× length of subgenital plate. Subgenital plate moderately long, nearly triangular, extending posteriorly beyond base of apophyses anteriores, weakly emarginated distomedially. Apophyses anteriores about 5/6 length of subgenital plate, with a pair of wedge-shaped sclerites posteriorly. Ductus bursae with a weakly sclerotized plate accompanied by a triangular sclerite at distal 2/3. Corpus bursae oval; signum small, about 1/3 width of corpus bursae, rhomboidal, surface with dense denticles.
Diagnosis. This species is unique in having the uncus with middle emargination extremely shallow; the gnathos with middle process short, not reaching anterior margin of tegumen, not hook-shaped but sub-triangular or only with an extremely short hook; the sacculus rather long and narrow, about 1/4 length of valva (Figs 6, 35– 35g). It can be further distinguished from its allies by the triangular subgenital plate in the female genitalia (Figs 40–43). In addition, this species with phallus bearing more microthorns (mostly more than thirty) than other species on average.
Variation. The shapes of uncus in different specimens can be variable within a small range, the details are illustrated in the figures 35– 35g.
Host plants. Fagaceae: Quercus sp.; Juglandaceae: Juglans mandshurica Maxim.; Salicaceae: Salix sp. (Liu & Bai 1979).
Distribution. China (Beijing, Hebei, Henan, Heilongjiang, Liaoning, Shanxi, Tianjin), Korea (Park & Karsholt 1999), Japan [?] (Park 2004; Park & Ponomarenko 2007; Park 2012).
Remarks. A few of specimens with phallus with less than twenty microthorns on distal half, which is in contrast with other specimens, we refrain from considering the number of microthorns as a diagnostic character. In addition, Park & Karsholt (1999) pointed out that “the male genitalia figured by Liu & Pai (1979: Fig. 12) under the name of gibbosella obviously belong to latignathosa ”, we agree with Park & Karsholt (1999), but another figure (Fig. 13) of male genitalia in Liu & Pai (1979) is distinctly belong to P. gibbosella, Liu & Pai (1979) also provided an illegible figure (Fig. 23) which was hand-painted of the female genitalia under the name P. gibbosella, we can’t confirm the female genitalia provided by Liu & Pai (1979) was actually belong to P. gibbosella or P. latignathosa, Park & Karsholt (1999) also indicated that the female of P. latignathosa was “unknown”, here we have given detailed description and diagnosis of the female genitalia under the name P. latignathosa.
As for the distribution of P. latignathosa, Park (2004), Park & Ponomarenko (2007) and Park (2012) mentioned that Japan is one of distribution localities. But the specimen mentioned in these literatures was the same one, the holotype of P. latignathosa. At present, there is no information about Japanese specimens. Therefore, the distribution of P. latignathosa in Japan is doubtful.
