BRYOPHILOCAPSUS
YASUNAGA, 2000
Bryophilocapsus
Yasunaga, 2000: 95
.
Type
species:
Bryophilocapsus tosamontanus
Yasunaga, 2000
(by monotypy).
Diagnosis
Recognized by the following combination of characters: antennal segment I about one-half the width of head and somewhat shorter than width of vertex; labium long, reaching apex of middle coxa; pronotal collar wider than width of antennal segment I; pronotum with shallow punctures; margin of exocorium convex; cuneal fracture incised; cuneus broadly triangular, slightly longer than basal width; membrane strongly deflect- ed; right paramere about twice as small as left paramere; left paramere falciform, with indistinct sensory lobe, apically dentate (see figs in
Yasunaga, 2000
). It is similar to
Monalocoris
in the short antennal segment I, incised cuneal fracture, and membrane deflected at base of cuneus, but has many distinctive features, e.g. larger size (3.0–3.6), pronotal collar distinctly wider than width of antennal segment I, and shape of left paramere.
Diversity and distribution
The genus was originally described and remains monotypic with
Bryophilocapsus tosamontanus
Yasunaga, 2000
known from Shikoku Island, southern
Japan
.
Remarks
In contrast to all other species of the tribe,
B. tosamontanus
was found on a thuidiaceous moss,
Thuidium cymbifolium
(Dozy & Molk.) Dozy & Molk.
(Bryophyta:
Thuidiaceae
). No material of this genus was available for examination; the above account is based on the original description and figures present- ed in
Yasunaga (2000)
.
COBALORRHYNCHUS
REUTER, 1906
FIGS 1, 2
Cobalorrhynchus
Reuter, 1906: 1
.
Type
species:
Cobalorrhynchus biquadrangulifer
Reuter, 1906
(by monotypy). Synonymized with
Bryocoris
Fallén
by
Yasunaga & Kerzhner, 1998: 88
. Restored to subgeneric status by
Hu & Zheng, 2000
.
Diagnosis
Recognized by the following combination of characters: labium reaching middle of mesosternum, labial segment IV claw-shaped, distinctly longer than wide, twice thinner than segment III, and strongly tapering from base; antennal segment I distinctly shorter than head width, but somewhat longer than vertex width; pronotal collar matt, slightly longer than width of antennal segment I, finely scalloped posteriorly; pronotum with shallow punctures; hemelytron in lateral view with narrow dark-brown line along entire costal margin, sometimes indistinct at base; genital capsule with large single-coned process above left paramere or without any processes; right paramere about twice as small as left paramere; left paramere falciform, with indistinct sensory lobe and almost straight, gradually tapering apical process; both sexes always macropterous.
The genus is most similar to
Bryocoris
in size range, overall body proportions, and colour pattern of hemelytron; however
Bryocoris
clearly differs from
Cobalorrhynchus
in the short and thick labial segment IV, absence of the brown line along costal margin, the genital capsule with characteristic twinconed process above the left paramere, the reduced right
paramere, the complex shape of left paramere with welldefined sensory lobe and twisted apical process, and the occurrence of brachyptery.
Diversity and distribution
Cobalorrhynchus
has 11 species:
Cobalorrhynchus biquadrangulifer
Reuter, 1906
comb. nov.
;
Cobalorrhynchus convexicollis
(Hsiao, 1941)
comb. nov.
;
Cobalorrhynchus flaviceps
(Zheng and Liu, 1992)
comb. nov.
;
Cobalorrhynchus hsiaoi
(Zheng and Liu, 1992)
comb. nov.
;
Cobalorrhynchus latiusculus
(Hu and Zheng, 2007)
comb. nov.
;
Cobalorrhynchus latus
(Lin, 2003)
comb. nov.
;
Cobalorrhynchus lii
(
Hu & Zheng, 2000
)
comb. nov.
;
Cobalorrhynchus lobatus
(
Hu & Zheng, 2000
)
comb. nov.
;
Cobalorrhynchus paravittatus
(Lin, 2003)
comb. nov.
;
Cobalorrhynchus sichuanensis
(
Hu & Zheng, 2000
)
comb. nov.
; and
Cobalorrhynchus vittatus
(
Hu & Zheng, 2000
)
comb. nov.
The distributional range of this genus is restricted to southern and central
China
(
Xizang
,
Sichuan
,
Gansu
,
Yunnan
,
Shaanxi
, and
Guangxi
provinces,
Taiwan)
with just one species,
C. hsiaoi
, also known from
Japan
.
Remarks
Hu & Zheng (2000)
defined
Cobalorrhynchus
in the currently accepted sense and treated it as a subgenus of
Bryocoris
without discussing the diagnostic features of the latter. Our results are fully congruent with the treatment of Hu and Zheng, but show little support for the monophyly of
Bryocoris
s.l.
Therefore, we propose regarding
Bryocoris
Fallén, 1829
and
Cobalorrhynchus
Reuter, 1906
as two separate genera.
