Cyrtodactylus quadrivirgatus —I.S. Law, I.T. Law & Serin, 2016: 117 (Upper Seletar Reservoir Park).— Figueroa & I.S. Law, 2021: 1 (Admiralty Park; CCNR; Mandai Track 15; Nee Soon Swamp Forest).—L.L. Grismer et al., 2021: 133.— Janssen & Sy, 2022: 75, 157.

Remarks. As mentioned in the earlier account for C. majulah , before being described as a new species C. majulah was known as C. quadrivirgatus (see Grismer et al. 2012). Then, on 17 July 2016, a live specimen of C. quadrivirgatus was photographed by Law et al. (2016) at a stream in the NSSF section of USRP. Since then, seven additional observations have been recorded with two predating the initial discovery ( Figueroa & Law 2021). These additional observations reveal that C. quadrivirgatus may likely share a similar distribution to C. majulah , but more surveys are needed to determine its distribution in Singapore. Thus far, C. quadrivirgatus is identified solely based on colour pattern ( Figueroa & Law 2021). Hence, explicit research is required comparing the Singapore populations to populations elsewhere to confirm its specific status.
