Bronchocela cristatellus —L.M. Chou, 1995: 147 . “Green Crested Tree Lizard”— Anonymous, 2014: 31 , 87 ( Singapore Polytechnic). Remarks. Bronchocela cristatella was first reported from Singapore based on specimens in NHMUK from Argent, Belcher, and Warwick ( Gray 1845 ). Perhaps because it was so common near urban areas, numerous specimens of B. cristatella were collected throughout the years (e.g., Girard 1858b ; Stoliczka 1870a; Hanitsch 1912a ), and MNHN-RA-1912.15 was collected on 2 January 1912 by an unknown collector. Flower (1896 , 1899b ) found B. cristatella abundant throughout Malaysia and Singapore , and Sworder (1925a) said it was one of the most common lizards in Singapore . Despite no new published observations for 39 years ( Table 2 ), aside from recently published records from 1944 and 1945 ( Cross 2020n ; Lim 2020 ), Johnson (1964) and Chuang (1973) still found B. cristatella common. Bronchocela cristatella remains common today, but Baker & Lim (2012) categorised it as uncommon because it has been outcompeted and largely displaced from most non-forested areas by the non-native Calotes versicolor ( Diong et al. 1994 ) . Calotes versicolor appeared in Singapore in the 1980s, likely reaching as a stowaway ( Lim & Chou 1990 ). Koh (1986) asserted that B. cristatella was still more common than C . versicolor , but by 1989 C . versicolor was already widespread and displacing B. cristatella ( Lim & Lim 1989 ) . By 1997, B. cristatella already seemed confined to forested areas (Teo & Rajathurai 1997). Given how rapid C . versicolor spread throughout Singapore within five years of its arrival, and that over 30 years elapsed since it first appeared, it seems apparent that B. cristatella has found refuge from C . versicolor’s invasion in Singapore’s forested areas. Occurrence. Widespread. Common. Singapore conservation status. Least Concern. Conservation priority. Moderate, because it is being outcompeted by Calotes versicolor , which is non-native. IUCN conservation status. Least Concern [2021]. LKCNHM & NHMUK Museum specimens.
