Vertomannus (Vertomannus) parvus sp. nov.

( Figures 5 , 11, 17)

Description. Head reddish brown, strongly shining, basal half and “neck” with long erect hairs. Neck of head substantially shorter than that of any other members of the genus, for nearly one-third of postocular distance. Antennae pale testaceous with distal end of segments II and III dark brown, segment IV dark brown with basal two-fifths yellow-white. Rostrum reaching about the anterior coxae.

Anterior pronotal lobe brightly reddish brown, impunctate and distinctly convex, collar, lateral margins and central area contrasting pruinose black and covered with dense punctures. Posterior pronotal lobe testaceous with lateral areas and posterolateral angles reddish brown, heavily covered with black-brown punctures. Hemelytra with bright colors, clavus and corium testaceous with apical corial angles brown, spots near basal area, before apical angles and in inner angles white. Clavus with three rows of punctures. Scutellum without a distinct elevation. Ventral and pleural surface of thorax reddish brown, prosternum, posterior margins of mesopleura, metapleura except for posterolateral lobe pruinose. Legs pale testaceous, distal half of femora becoming dark, fore femora ventrally armed with two spines.

Ventral surface of abdomen testaceous, shining, covered with sparse pubescences in females or with long erect hairs in males. Male paramere (Figure 17) with blade slim, outer projection finger-like, inner projection broad triangular, sperm reservoir with (Fig. 11) a pair of acutely pointed lobes behind its body.

Measurements (n=4). Length of head 1.13 (1.10–1.16), width 0.89 (0.85–0.92), interocular space 0.57 (0.55– 0.60). Length of antennal segments I 0.41 (0.40–0.42), II 1.23 (1.20–1.26), III 0.87 (0.85–0.92), IV 1.02 (1.0– 1.04). Length of pronotum 0.77 (0.75–0.80), width of anterior pronotal margin 0.53 (0.50–0.56), width of posterior pronotal margin 1.03 (1.0–1.05). Length of scutellum 0.47 (0.45–0.50), width 0.47 (0.45–0.50). Midline distance apex clavus–apex corium 1.05 (1. 0–1.10), midline distance apex corium–apex membrane 1.15 (1.10–1.20). Total body length of male 4.57 (4.5–4.6, n=2), female 4.8.

Type material. Holotype, male, China, Yunnan, Tengchong, Zhengding, alt. 1600–2000m, 3-X-2002, leg. Huaijun Xue. Paratypes: 1 male, China, Yunnan, Tengchong, Dahaoping, alt. 2000m, 24-IX-2002, leg. Huaijun Xue; 1 male, China, Yunnan, Baoshan, Mt. Baihua, alt. 1550m, 21-IX-2002, leg. Huaijun Xue; 1 female, China, Yunnan, Lvchun, alt. 1996m, 30-V-1996, leg. Wenjun Bu.

Etymology. parvus alludes to this new species’ short body compared to other species of the genus Vertomannus.

Distribution. China (Yunnan).

Remarks. This new species can be readily distinguished from all other Vertomannus species by the head with a very short “neck” and a small body. It resembles V.(V.) brevicollum Zheng in having fore femora not incrassate, the fore tibiae straight, the anterior pronotal lobe not longer than the posterior lobe, the neck of the head not longer than the postocular distance; but the fore femora of the new species armed with two spines (there is only one in V.(V.) brevicollum ), the color pattern of antennae and pronotum, paramere and sperm reservoir are also different.
