Aradus tonkinensis Kormilev & Heiss 1976

Aradus tonkinensis Kormilev & Heiss 1976 (Fig. 20,21, Photo 3) Material examined: 1♀, China, Yunnan / Kubalung Mts. 25-28 06 92 / V. Kuban lg. (CEHI); 1♀, Laos-N, 24 IV-16 V 1999 / Louang Phrabang Prov. / 20°33-4’ N 102°14’ E / Ban Song Cha (5km W) / 1200m, Vit Kuban lg. (CEHI). Described from Vietnam, the abovementioned records in the collection CEHI are included here as they are the first ones known since the description of tonkinensis and represent therefore also a new record for the Chinese fauna. Habitus, size, and colouration of A. tonkinensis are very close to A. spinicollis Jakovlev 1880, known from several provinces of China (Heiss 2001b, 2010); it can be confounded with the latter. In tonkinensis the antennae are more slender and relatively longer (compare Figs. 20,21 with Figs. 22,23 and Photos 3 and 4), the preocular acute tubercle is longer, and the paranota are more expanded and dentate; the scutellum is distinctly constricted at its posterior half and the posterolateral angles of dorsal external laterotergites (deltg) are more produced, particularly in the female.Published as part of Bai, X., Heiss, E. & Cai, W., 2010, New records, a synonymy and a new species of Aradus Fabricius, 1803 (Hemiptera: Heteroptera: Aradidae) from China, pp. 59-68 in Zootaxa 2388 (1) on page 62, DOI: 10.11646/zootaxa.2388.1.5, http://zenodo.org/record/530700
