Filling the gaps: Additional notes on the reproduction of the Kühne's Grass Lizard (Takydromus kuehnei Van Denburgh, 1909; Squamata: Lacertidae) from southwestern Taiwan

The Kühne's Grass Lizard (Takydromus kuehnei) is a poorly studied indigenous species in Taiwan. In this report we incorporate additional information concerning reproduction with our previous observations to provide a more comprehensive description of reproduction in T. kuehnei from southwestern Taiwan. We collected 48 T. kuehnei (18 male, 19 female) from a secondary forest in Santzepu, Sheishan District, Chiayi County, as part of a herpetofauna survey in the area. We also obtained five clutches of eggs from these lizards. The smallest reproductively active female was 49 mm snout-vent length (SVL). Oviposition took place from April to July. Clutch sizes ranged from one to two eggs with an average of 1.8. A histological examination of five museum specimens confirmed that females may produce multiple clutches in the same year. We obtained 11 eggs that had an average length, width, and mass of 10.6 mm, 6.1 mm, and 1.8 g, respectively. The average relative clutch mass was 16.7%. Five eggs successfully hatched after an average incubation period of 32.6 days. The hatchlings had an average SVL of 23.8 mm, total length of 51.4 mm, and mass of 0.3 g.
