Additional Notes on the Reproduction of the Formosan Grass Lizard, Takydromus formosanus (Boulenger, 1894) (Squamata: Lacertidae), from Southwestern Taiwan

Abstract

We collected 13 (male = 2; female = 10; juvenile = 1) Takydromus formosanus on an ad hoc basis from a Betelnut Palm (Areca catechu) plantation in Santzepu, Sheishan District, Chiayi County, as part of a herpetofaunal survey of the area. The smallest reproductively active female had a snout-vent length (SVL) of 44mm, and the smallest male with an enlarged tail base had a SVL of 41 mm. A histological examination and oviposition indicated that the female reproductive cycle commences in April and lasts until at least June. We recorded no clutch sizes greater than two eggs. Takydromus formosanus is a poorly studied species, and many aspects of the reproductive biology of this species merit further research.
