Diagnosis
.
Oodes integer
is distinguished from other species of
Oodes
except
O
.
tokyoensis
by the lack of longer and denser, yellowish hairiness on the ventral surface of meso- and metatarsomeres 2–4, rather large size, 10.0–
10.5 mm
(
Table 4
), prosternal process with apex elongate and narrow, and discontinuous granulation in elytral marginal furrow. The species is most similar to
O
.
tokyoensis
(see “Notes”).
Oodes helopioides
and
O
.
integer
differ further from each other in PW/PL, EL/EW, and the shape of the prosternal process apices (
Figs 18J
,
20E
).
Description
.
Habitus
. Specimens of large size (BL:
10.1–10.3 mm
, BW: 3.7–4.0 mm), with subovate and subconvex body (
Figs 20A, C
).
Ratios and measurements
. See
Table 4
.
Color and luster
.
Body dark brown to black, pronotum laterally and posterolaterally rufous, antennae, palpi and legs rufopiceous. Integument moderately shiny, without iridescence.
Punctuation
. Dorsal surface without punctuation; proepisternum and sides of prosternum with punctuation rare and more scattered than that on sides of metasternum, meso- and metepisternum; proepisternum, abdominal ventrites 1–5 at sides, and ventrite 6 at apex finely rugose.
Head
. About half as wide as pronotum (see
Table 4
).
Mentum
tooth with apex rounded and distinct paramedial border (
Fig. 20D
).
Thorax
. Pronotum (
Fig. 20B
) with sides rounded toward posterior angles (PW/PB: 1.04–1.05); maximum width in posterior fifth; laterobasal impressions indistinct; base slightly sinuate; anterior angles rounded, moderately projected anteriorly. Prosternum with median longitudinal sulcus very shallow; prosternal process bordered throughout, with slightly pointed apex (
Fig. 20E
). Metepisternum longer than wide (MA/MM: 0.91–0.92), with lateral margin concave posteriorly and coadunation with epipleuron short, located anteriorly (
Fig. 20F
).
Elytra
.
Apical sinuation moderate, well-defined. Basal margin distinct laterally, forming a minute denticle at shoulder, disappearing medially at level of stria 3. Granulation in marginal furrow discontinuous, interrupted in second fourth. Parascutellar striola and other striae punctate; stria 7 as distinct as stria 6. Intervals 1–7 rather flat, interval 8 subconvex.
Legs
. Metacoxal basal sulcus extending to lateral fifth. Male mesotibia moderately modified, with slight swelling in apical half. Protarsomeres 1–3 of male moderately dilated, with second segment barely wider than long (W/Lp2:1.05).
Male genitalia
. Not examined (see “Notes”).
Female genitalia
. Basal gonocoxite with six lateroapical setae arranged in line. Apical gonocoxite with single, very small dorsolateral ensiform seta, without nematiform setae (
Fig. 20G
). Spermatheca coiled apically (
Fig. 20H
).

A, C: habitus B: pronotum and head; D: mentum; E: prosternal process; F: left metepisternum and metacoxa (arrow shows lateral end of metacoxal basal sulcus); G: left gonocoxite, ventral view; H: spermathecal complex and gonocoxites, ventral view. Scale lines = 2 mm (Figs A, C); = 1 mm (Figs B, D, F); = 0.5 mm (Figs E, H); = 0.2 mm (Fig. G).
Distribution
. Eastern Palaearctic Region: Russian Far East,
Korea
(
Kim
et al
. 1994
). Not yet recorded from
China
, but
Lafer (1989)
suggested it may occur in the northeastern part of the country.
Notes
. The species is most similar to
O
.
tokyoensis
in the shape of prosternal process (compare
Habu 1956: 86
, fig. 18;
Lafer 1973: 848
, fig. 6; present work,
Fig. 20E
) and general structure of gonocoxite which lack nematiform setae (compare
Habu 1956: 101
, fig. 35 and present work,
Fig. 20G
). Besides,
Lafer (1973
, figs 9, 10) and
Habu (1956
, fig. 23a, d) provided drawings of the median lobes of
O
.
integer
and
O
.
helopioides tokyoensis
, respectively, which show great similarity. Without comparison and access to the
type
specimens of both species, it is difficult to define the diagnostic features of either.
The specimens examined from the Kommisarovka River are partly teneral, with appendages seemingly lighter than in mature specimens. The genitalia of the male specimen are not chitinized, so it was not possible to study them.
The original name of the village Bezverkhovo was Ust Sidimi (‘Усть–Сидими’, or ‘Сидими’, in Russian), named for Sidimi Bay on which coast the village was founded.
Sundukov (2013: 190)
stated that the
type
locality of
O
.
integer
is ‘Wladiwostok’ thus omitting the more precise ‘Sidémi’ (= Bezverkhovo); the latter located
35–40 km
southwest of Vladivostok City.
As
Lafer (1973)
supposed,
Jakobson (1906)
was the first to formally propose the synonymy of
Oodes integer
with
Lachnocrepis prolixa
. Soon afterwards,
Reitter (1908)
proposed the same synonymy independently. However,
Habu (1956)
did not accept this identity, based on similarities of
O
.
integer
with
O
.
helopioides tokyoensis
.
Lafer (1973)
found and investigated the
type
specimens of
O
.
integer
and listed their labels: ‘Сидеми 12 IX 87 (οк. Владивοстοка). М. Янкοвский //
Oodes integer
m.

sec. Heyden // coll. Semenov-Tian-Shansky’. Most likely the labels added by Lucas von Heyden were the reason for the confusion of
O

with
