I) Decurved Sri-Lankan twighopper, Cladonotus humbertianus (Saussure, 1862) Tettix (Cladonotus) humbertianus: Saussure, 1862: 478. Cladonotus humbertianus: Walker 1871: 842, Bolívar 1887: 209, Hancock 1904: 113, 1907: 16, 1915: 62, Kirby 1910: 9, 1914: 17, Sandrasagara 1950: 136, Blackith 1992: 22, Hollier 2013: 211. Distribution. Sri Lanka: Peradeniya (see Table 1), Trincomalee (N8.594306, E81.167916) (Saussure 1862), Kandy (for coordinates see Table 1), Gammaduwa: Mavusakanda (= probably Mousakanda Estate) (N7.568020, E80.696309) (Sandrasagara 1950). Habitat. Rainforests. Notes. The decurved Sri-Lankan twighopper has been reported once (Sandrasagara 1950) since the description (Saussure 1862). Syntypes were collected more than 150 years ago, around Peradeniya and Trincomalee (Saussure 1862). In the original description, Saussure (1862) placed this species in the genus Tettix Charp., newly founded subgenus Cladonotus. Because the original combination was Tettix (Cladonotus) humbertianus, the author should be written in brackets according to Article 51.3. of the International Code of the Zoological Nomenclature (ICZN 1999). Besides the type material (MHNG), there are a few specimens of this species in the Colombo Museum, Sri Lanka (Sandrasagara 1950), which should be studied and digitalized in future.
