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.
