( Fig. 4 ; Photo 2)

Material examined: Holotype male labeled: Vietnam, Vinphuc Pro./ Melinh 200m / N 21°18’, E 105°47’ / 2 X 2011 Bai,Pham / Ent.Mus. IMNU Huhhot // deposited in IMNU; paratypes 4 males, 1 female collected with holotype, CEHI, IMNU; 1 female: N-Vietnam 370m / 52m SW Wang Son / 21,35 N, 106,30 E IV–V 96 / Pacholatko-Dembicky // CEHI. The types are designated and labeled accordingly.

Diagnosis. Small macropterous species without a transverse sulcus on pronotum and a pair of small prominent tubercles at base of anterior pronotal lobe. The latter character is also shared by membranaceus and loebli n.sp. but differs from both by the lack of transverse pronotal sulcus.

Description. Coloration brown with whitish incrustations on head, pronotum and abdomen; posterior lobe of pronotum glabrous.

Head. Slightly wider than long (25/21); antennae slender 1.9x as long as width of head (47.5/25), length of antennal segments I/II/III/IV =11/7/14.5/13, ratio segment III/II 2.07; Pronotum. 1.62x as long as wide (52/32), anterior lobe narrower (42), lateral margins sinuate, anterolateral angles rounded.

PHOTOS 1–6. Lissonotocoris spp. 1 — membranaceus from China (Hainan); 2 — glabronotus n.sp., paratype female from Vietnam (Wang Son); 3 — loebli n.sp., holotype male from Thailand (Khaeng Krachen N.P.); 4 — siamensis n.sp., holotype male from Thailand (Khao Yai N.P.); 5 — pachycerus n.sp., holotype female from Malaysia ( Cameron Highlands); 6 — loebli n.sp., paratype male, ventral view.

Measurements: Holotype male: length 3.50 mm; length of antennae 1.18 mm, width of abdomen across tergite IV 0.77 mm; Paratype female: length 3.9 mm, length of antennae 1.35 mm; length of antennal segments I/II/ III/IV = 13/8/18 /15, ratio segments III/II 2.25; width of abdomen across tergite IV 0.87 mm.

Etymology. Referring to the glabrous posterior pronotal lobe which is uninterrupted by a transverse sulcus. Distribution. Recorded from 2 localities in N-Vietnam.
