Barred Kukri Snake

distribution

Distribution. Based on Chan and Ahmad (2009), this rare species was reported to occur in the states of Selangor, Melaka, Johor, Pahang, and Negeri Sembilan. From the previous reports (e. g., Tweedie 1954; Hendrickson 1966), this species was only recorded in the southern part of Peninsular Malaysia. The findings of this study extended its distribution range to the northwestern part of Peninsular Malaysia, with a new locality.

discussion

Remarks. Tillack & Ģnther (2009) noted that several authors called into question the occurrence of O. signatus in Singapore, beginning with Ģnther (1864) who noted that the two specimens he examined are “ said to be from Singapore; but whether this is their real native place, or they have been merely procured there, is uncertain ”. It is likely that subsequent authors are referring to Ģnther (1864). However, not long after Ģnther (1864), Sclater (1891) reported a specimen collected by Davison, and Hanitsch (1899) reported a specimen collected by Ridley at SBG in March 1897 which he found under a pile of tiles (Ridley 1899). The first report of O. signatus from Singapore comes from Ģnther (1863) who noted that NHMUK procured new specimens in 1863. A year later, Ģnther (1864) used the specimens to describe O. signatus as a new species, but he was unsure whether the specimens originated from Singapore (Table 1). In addition, he described each specimen as a variety. Indeed, Boulenger (1894) indicated that Hardwicke and Haslar collected the two specimens from Singapore. Cross (2020 g, k) recorded a few individuals in 1944 that went unpublished until now (Lim 2020). Later, Tweedie (1952)
