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.
