Original description:
Metrioptera ussuriana Uvarov 1926 Ann. Mag. Nat. Hist. (9)17: 282, fig. 8.

  ♂. Similar in general appearance to M. roeselii (Hag.).
  Pronotum with the disc distinctly widened behind; metazona impressed, obsoletely punctured, with a distinct median carina, very broadly rounded, practically truncate, behind. Lateral lobes distinctly longer than deep, with the hind margin very long, strongly obliquely ascending, and perfectly straight.
  Elytra broad, inflated, reaching beyond the middle of abdomen, widened towards the apex which is very broadly rounded. Speculum large, angulate, without veinlets.
  Last abdominal tergite with a pair of large, subtriangular, divergent lobes. Cerci short, but with the basla portion very thick; apex short conical; armed inwardly with a very long, slightly curved, postbasal spine, attenuate apically, but with the immediate apex incrassate. Subgenital plate long, tectiform, with the median carina sharp and two thick parallel lateral carinae; hind margin deeply and acutely excised; styli long.
  General coloration reddish castaneous. Head paler; apex of fastigium castaneous; postocular fasciae broad, blackish brown, with a narrow pale median line. Lateral lobes of pronotum chocolate-brown, shining, with the lower and hind margin not broadly yellowish. Elytra semitransparent, brownish infumate, with few of the veins partly blackish; apical part with indistinct small darkish spots. Hind femora brownish stramineous, outer area with black longitudinal stripe, emitting short transverse branches on both its sides.
  Total length 17; pronotum 5.5; elytra 9; hind femur 16 ㎜.
  A single male from the district Spassky, prov. Primorskaya, 12. vii. 1924.
  As will be seen from the description, the resemblance of this species to
M. roeselii is only superficial, there being striking differences in the shape of pronotum, of elytra, and particularly, of external genitalia, which make the new species very easily recognizable.
