Diagnosis. This subspecies is close to E. chrysochloris chrysargyrea , but differs by the larger black elytral maculae; outer angle of elytral apex angulate and apparently becoming more strongly angulate in specimens collected further north. Frons of male about twice width of inferior eye-lobe.

In the original description of Glenea chrysochloris, Bates (1879) compared it with two species in the note as follows: “Differs from the allied G. swinhoei by the metallic-coloured clothing of the body. In this respect it agrees with the East-Siberian G. metallescens ( Saperda id., Motsch.), from which its large black markings conspicuously distinguish it. The elytral spots are, on each side two large and angular, placed in succession on the disk before the middle, and one describing nearly an oval between the middle and the apex; the shoulders and lateral carinae of the elytra are also black. The elytra are briefly truncated at the apex, with a short tooth at the external angle of the truncature. The apex of the tibiae is black, the tarsi above pale blue. The antennae are black, with the basal joints more or less marked with blue.” Also in Bates (1884), he distinguished it from E. chrysargyrea by the following note: “Resembles E. chrysargyrea in its black markings and the form and colour of the elytral carinae; the spots are, however, much larger, the elytra have the external angle of the truncature briefly spinose.”

Host plants. Alnus sp. ( Betulaceae ), Pinus tabulaeformis Hort. ex C. Koch (Pinaceae) , Populus sp. ( Salicaceae ), Tilia japonica (Miquel) Simonkai (Tiliaceae) .

Remarks. One male figured by Wang (2014: 721, fig. 3417.1) from Hunan, Nanyue looks quite similar to Eutetrapha chrysochloris chrysochloris ( Bates, 1879) , especially due to the elongated black maculae on the pronotum and the black arc on the apical half of the elytron. But no conclusion can be made without studying specimens. The records from Henan and Sichuan could not be clarified without available specimens.

The records from Shaanxi, Hubei and Gansu should be based on E. shaanxiana Lin & Yang , sp. nov. However, the record from Zhejiang would be E. tianmushana Lin & Bi , sp. nov. The record from Taiwan appeared in Hua (2002) and was repeated by Löbl & Smetana (2010), but it was not included in the Taiwanese faunal books ( Yu & Nara 1988; Yu et al. 2002; Chou 2004; Chou 2008) or catalogue ( Nakamura et al. 1992; Nakamura et al. 2014). We agree with the latter authors and do not believe that this species occurs in Taiwan.

Distribution. Japan, Russia.
