Trachypeplus jacobsoni (not Horváth): Jing, 1981: 314, misidentification.
Description. Body brown (Fig. 4); head dark brown, antennae and leg brown, but fourth antennal segment and apex of tarsus dark brown; calli black; thorax ventrally dark brown or black; abdomen ventrally brown. Female paler than male, light yellowish brown (Fig. 5).
Head densely covered with yellowish brown pruinosity; spines long, slender, suberected, pointed forwards (Fig. 14). Antennae relatively short, first two antennal segments stouter, third one slender, nearly two times as long as fourth one, last inflated. Bucculae covered with many scale-like hairs, mostly biseriate, apex a little surpassing in front of clypeus, closed in front. Rostral sulcus nearly parallel but slightly widened posteriorly (Fig. 32); rostrum reaching posterior margin of mesosternum.
Pronotum long, slightly gibbose (Fig. 14), covered with many scale-like hairs (Fig. 24). Collar biseriate wide, median portion raised as a small hood, bell-shape dorsally, but dorsal margin nearly straight in lateral view, produced forwards (Fig. 14). Three carinae subparallel, indistinctly uniseriate; lateral carinae as high as median carina. Paranota triseriate broad anteriorly, then gradually narrow behind, biseriate opposite humeri; greatly reflexed, mostly resting onto pronotum, but outer margins slightly elevated. Distance between outer margin of paranotum and lateral carina narrow anteriorly; posteriorly, this distance widening and slightly wider than that between lateral and median carinae. Distance between lateral and median carinae on posterior pronotal process triseriate. Anterior margin of collar, dorsal margin of head and carinae, longitudinal ridges of areolae on paranota armed with many tubercle-spines (tubercle apically armed with a short spine) regularly spaced, tubercle long, slender, twice longer than spine on tubercle.
Hemelytra long, wider than pronotum, each area covered with many scale-like hairs, costal and boundary veins raised and armed with a row of tubercle-spines regularly spaced, but tubercle shorter than that on pronotum. Costal area biseriate uniformly all along. Subcostal area narrower than costal area, erected, biseriate. Discoidal area extending backwards, nearly as long as 2/3 of hemelytra, eight areolae broad at widest part. Sutural area seven to eight areolae broad at widest part. Hypocostal area narrow, uniseriate, areolae small.
Measurements. Males (N =1) and females (N =1) respectively. Body length: M, 2.36, F, 2.36; width: M, 1.06, F, 1.16. Length of pronotum: M, 1.22, F, 1.22; width: M, 0.84, F, 0.88. Length of hemelytra: M, 1.60, F, 1.56. Length of discoidal area: M, 1.00, F. 1.03. Antennal segments measurements: M, I: 0.10, II: 0.08, III: 0.40, IV: 0.22; F, I: 0.10, II: 0.08; III: 0.38; IV: 0.20.
Material examined. Holotype: male, China, Yunnan Province, Xishuangbanna, Xinmanbing, 21.V.1958, No. IOZ(E)535921 (IZAS). Paratype: 1 female, China, Yunnan Province, Xishuangbanna, Menglong Township, Mengsong Village, 22.IV.1958, No. IOZ(E)535922 (IZAS).
Etymology. The specific name refers to Prof. Xili Jing, in honor of her contribution to the studies of Chinese Tingidae.
Comment. This new species is based on two specimens misidentified as Trachypeplus jacobsoni Horváth, 1926 by Jing (1981: 314). Personal examination of the digital photographs of the type of T. jacobsoni, prepared by Yvonne D. van Nierop of NCB Naturalis, and examination of Hainan specimens of T. jacobsoni, show that the new species differs from T. jacobsoni by its hood being flattened above with the dorsal margin nearly straight in lateral view (the hood distinctly elevated with the dorsal margin distinctly arched in T. jacobsoni) (Figs. 14–15), its sulcus laminae on the metasternum nearly straight (sulcus laminae arched, cordate in T. jacobsoni) (Figs. 32–33).
Trachypeplus jingae sp. nov. differs from T. bakeri Drake, 1927 (Philippines) by its narrower costal area (biseriate vs. quadriseriate) and its body densely covered with many scale-like hairs (in T. bakeri, the body sparsely clothed with short scale-like hairs).
