Tambinia bambusana sp. nov., anew bamboo-feeding species of Tambiniini (Hemiptera: Fulgoromorpha: Tropiduchidae) from China.

The tropiduchid planthopper genus Tambinia (Tropiduchidae: Tambiniini) was established by Stal (1859) with 3 new species from Sri Lanka (type species: T, languida Stal, 1859). Since then, 21 species have been added to the genus, from Sri Lanka (5 species) (Distant 1906, 1916), China (4 species) (Matsumura 1914; Liang & Jiang 2003; Men et al. 2009; Wang & Liang 2011), India (4 species) (Distant 1906, 1916; Muir 1931), Malaysia (4 species) (Distant 1906; Fennah 1982; Wang & Liang 2011), Papua New Guinea (4 species) (Melichar 1914; Metcalf 1954; Wang & Liang 2011), Vietnam (3 species) (Liang & Jiang 2003; Wang & Liang 2011), Burma (2 species) (Distant 1906), Australia (2 species) (Kirkaldy 1906; Wang & Liang 2011), Micronesia (2 species) (Metcalf 1946; Fennah 1956), the Philippines (1 species) (Fennah 1970), Japan (1 species) (Matsumura 1914), Malacca (1 species) (Metcalf 1954), Singapore (1 species) (Metcalf 1954), Laos (1 species) (Liang & Jiang 2003) and Tanzania (1 species) (Wilson 1986).

The tropiduchid fauna of China remains inadequately studied. The 5 species recorded are: T. bizonata Matsumuru, 1914 (Taiwan), T. debilis Stal, 1859 (Guangdong, Fujian, Jiangxi, Hunan, Zhejiang, Anhui, Henan, Hong Kong and Taiwan), T. menglunensis Men & Qin, 2009 (Yunnan), T. rubrolineata Liang, 2003 (Hainan and Yunnan) and T. similis Liang, 2003 (Hainan and Yunnan). There is little biological information about the genus. T. vertically Distant was found breeding on coconuts in Zanzibar, Tanzania (Wilson 1986). T. theivora Fennah was collected on tea in Malay Peninsula (Fennah 1982). T. capitata Distant was recorded feeding on African oil-palm (Wilson 1986). In China, T, debilis Stal was recorded attacking tea plant (Zhang et al. 2004).

During a study of species biodiversity of the bamboo-feeding planthoppers in China, several specimens belonging to an undescribed species of Tambinia were found on one native bamboo, Dendrocalamus latiflorus Munro (Poaceae: Bambusoideae). This represents the first record of the members of genus Tambinia Stal feeding on bamboo. The purpose of this paper is to describe this new species, T. bambusana sp. nov. and to provided a key to all species oiTambinia.


Morphological terminology follows Wang et al. (2009) and Wang & Liang (2011). Dry specimens were used for the descriptions and illustrations. External morphology was observed under a stereoscopic microscope and characters were measured with an ocular micrometer. Body length is measured from the apex of the head to the apex of the forewing in repose. The genital segments of the examined specimens were macerated in 10% KOH, washed in water and transferred to glycerine. Illustrations of the specimens were made with a Leica MZ 12.5 stereomicroscope. Photographs of the types were taken with a Leica D-lux 3 digital camera. The digital images were then imported into Adobe Photoshop 8.0 for labeling and plate composition. The type specimens are deposited in the Institute of Entomology, Guizhou University, Guiyang, China (IEGU), and the Natural History Museum, London (BMNH).

Frons flat, disc slightly depressed, longer in middle than the widest breadth (1.6: 1.0), lateral margins of frons incurved below level of socket of antennae, with basal part of median carina broad then thickened. Clypeus triangular, with thin median carina. Pronotum distinctly shorter than mesonotum in midline (1.0: 3.8), carinae strongly ridged, lateral carinae diverging posteriorly, median carina distinct, reaching posterior margin.
