| Distribution | C Taiwan Type locality: Su-ao, Yilan County, Taiwan (24° 35’ 23.4” N, 121° 51’ 37.5” E), elevation 10 m. |
| Reproduction | oviparous |
| Types | Holotype: NMNS 4431, an adult male. Captured when perching on high grasslands (Miscanthus sinensis) near the coastline. Collected at night on 21 June 2003 by Yu-Jun Hong, How-Ying Hsu, Yi-Fen Chen, and Si-Min Lin. Deposited in Natural Museum of Natural Science, Taichung, Taiwan. |
| Diagnosis | Diagnosis: Number of chin shields and femoral pores are commonly applied as the most important characters distinguishing among the Takydromus species in Taiwan and adjacent regions. Only 4 among the 19 currently recognized species in this genus exhibit ‘‘3 pairs of chin shields’’ and ‘‘2 pairs of femoral pores’’: T. hsuehshanensis, T. formosanus, T. viridi- punctatus, and T. luyeanus (Table 3 in LUE & LIN 2008). Conjunction of these two characters helps to separate these four species from the others. Takydromus viridipunctatus can be distin- guished from T. hsuehshanensis by its keeled ventrals. Takydromus hsuehshanensis is the only one among the four that has smooth ventrals. Takydromus hsuehshanensis has a comparatively robust body shape, stronger limbs and toes, a shorter tail without curling ability, and poor ability to climb on vegetation (Huang, 1998; and K.-Y. Lue and S.-M. Lin, personal observation). |
| Comment | Similar species: This species has been previously confused with Takydromus formosanus. In contrast to T. formosanus T. viridipunctatus and T. luyeanus exhibit prominent sexual dichromatism, have males and females with similar body sizes but differ in their head lengths and HL/SVL ratios. Similar species: Takyxdromus viridipunctatus and T. luyeanus were misidentified as T. formosanus in previous decades (Lue & Lin 2008). |
| Etymology | This specific name refers to the ‘‘green spotted’’ (viridi + punctatus) |
