Diagnosis
. Members of this species are readily distinguished from all other representatives of
Pseudoodes
by the longest metepisternum (MA/MM ≤0.81) and widest body (BW>
6.10 mm
,
Table 2
). In addition,
P
.
ampliusculus
can be differentiated from
P
.
subcoriaceus
, which is the only other member of the genus with body size more than
15 mm
, by PW/HW>2.10 and PW/PA>1.90; from both
P
.
cribristernis
and
P
.
vicarius
by its larger size; and from
P
.
coelestinus
by its black color of dorsum and larger size. The new species differs from taxa of the “
rambouseki
” group in its larger size, more than
15 mm
, greater values of PW/PL and EL/PL, and metepisternum longer than wide (MA/MM <0.9).
Description
.
Habitus
. Specimens of large size (BL:
15.5–15.7 mm
, BW:
6.20–6.65 mm
), with ovate and subconvex body (
Fig. 8A
).
Ratios and measurements
. See
Table 2
.
Color and luster
. Body black; antennae, palpi and tarsomeres rufopiceous, remaining parts of legs piceous. Integument moderately shiny, without iridescence.
Punctuation
. Dorsal surface without punctuation (in
holotype
only, posterolateral parts of pronotum, with large, moderately deep punctures extending laterally to anterior third); meso- and metepisternum entirely, prosternum, proepisternum, and metasternum at sides finely and densely punctate; abdominal ventrites 1–5 finely rugose and punctate at sides, ventrite 6 punctate at apex.
Head
. Less than half as wide as pronotum (
Table 2
).
Mentum
tooth truncate, with distinct paramedial border (
Fig. 8B
).
Thorax
. Pronotum with sides slightly rounded toward posterior angles (PW/PB: 1.04–1.05); maximum width at posterior third; laterobasal impressions very faint, almost indistinct; base moderately sinuate; anterior angles widely rounded, barely projected. Prosternum with median longitudinal sulcus moderately distinct; prosternal process elliptic, with rounded apex (
Fig. 8C
). Metepisternum longer than wide (MA/MM: 0.78–0.81), with lateral margin straight posteriorly, coadunation with epipleuron long, located anteriorly (
Fig. 8D
).
Elytra
. Apical sinuation moderate, well-defined. Basal margin distinct laterally, forming a small denticle at shoulder, disappearing medially at level of stria 3. Parascutellar striola distinct, less impressed than other striae; striola punctate, striae 1–4 punctate in basal sixth, striae 5–8 impunctate. Intervals 1–4 flat, 5–7 subconvex, 8 more convex than intervals 5-7.
Legs
. Metacoxal basal sulcus extended to lateral third.
Male genitalia
. Unknown.
Female genitalia
. Basal gonocoxite with four or five lateroapical setae situated in line. Apical gonocoxite stout, with very tiny dorsolateral ensiform setae, dorsomedial ensiform seta at base, and nematiform setae equidistant from middle and apex (
Fig. 8E
).
Bursa
copulatrix with a large dorsal sclerite; spermatheca moderately long, less differentiated than in species of “
cribristernis
” group, with receptaculum twisted apically; spermathecal gland connected in apical third of seminal canal (
Fig. 8F
).
Etymology
. The specific epithet,
ampliusculus
is Latin for “fairly large, considerable”, to stress the large size of body.
Distribution
.
China
(
Hainan Province
),
Vietnam
(
Hòa Bình Province
),
Thailand
(
Surat Thani Province
).
Bionomics
. The place in Mingfenggu where the
holotype
was caught is wet, and located very close to a lake. The specimen from the Khao Sok National Park,
Thailand
, was collected by light trap, located close to a pond.
