Flower (1896, 1899b) first recorded H. typus from Singapore from two individuals he collected at Fort Canning. Hemiphyllodactylus typus then went unrecorded in Singapore for 94 years (Table 2) until a photograph of ZRC.2.3282 collected on 24 October 1991 at UPR was illustrated in Lim & Lim (1992).

Then, a couple of years later one was found at SRF on 7 May 1993, and two others were found at MM

and UPR ( Lim 1993a). These records indicated that H. typus was wide-ranging throughout Singapore ,

but Baker & Lim (2012) classified its distribution as restricted to known localities ( CNR, MM, and WC). Subsequently, H. typus was found at Bidadari Park (Thomas 2013), PRPM (Tay & Wind 2013), Mandai (R.

Subaraj 2015), SBG (Ng 2017a), PU (Teo & Thomas 2019), and DFNP ( Fig. 14A ), KM, Tengah Forest , and Woodlands North Coast (A. Figueroa pers. obs.). Occurrence. Wide-ranging. Uncommon. Singapore conservation status. Near-Threatened. Conservation priority. Moderate. IUCN conservation status. Least Concern [2021]. LKCNHM & NHMUK Museum specimens.
