Diagnosis. On wing pattern, the forewing antemedial and postmedial lines of P. boarmiata are traceable as in P. szetschwana , while, the wedge-shaped patch is like an arrow, smaller and narrower. Forewing discal spot is rounded and not as elongate as in P. szetschwana ; antemedial line patch on the inner margin is almost unmodified in shape, at least in P. boarmiata boarmiata and P. boarmiata subcuneata . The male genitalia are close to those of P. conferta , P. moderata and P. fulvaria , while the distal part of the valva is more curved than in the other three species. P. boarmiata is one of four species (the others being P. falcipennis , P. bluethgeni and P. breviprotrusa ) which lack short spines on the vesica, but the cornutus is much longer and more pointed than in P. bluethgeni and P. breviprotrusa , and the manica lacks the two small pointed processes present in P. falcipennis . The female genitalia share a very long and narrow antrum, ductus bursae, and rounded corpus bursae with P. cuneata , while the joint between antrum and ductus is not expanded suddenly as in P. cuneata .

Distribution. China (Heilongjiang, Jilin), Japan, Russia (Amurland); newly recorded for China.

Remarks. Three subspecies of P. boarmiata have been described: P. boarmiata boarmiata Graeser, 1892 is distributed in Russia (Amurland) and China (Heilongjiang and Jilin Provinces), P. boarmiata subcuneata Inoue, 1954 ( Tinea 1 (2): 38, figs 1, 2) is distributed in Japan (Nagano Prefecture, Kamikôchi) and boarmiata masuii Inoue, 1982 (in Inoue et al., Moths of Japan: 562, pl. 103, fig. 11) is also found in Japan (Shikoku, Tokushima Prefecture, Mt Tsurugi). P. boarmiata subcuneata has much fainter wing decoration and longer and narrower valvae in the male genitalia than the nominate subspecies.
