Remarks. Being a highly variable species, up to seven varieties of C. intestinalis were identified (Boulenger 1896), yet most researchers followed the designations provided in Golay (1993) and recognised six subspecies. The different varieties spawned a taxonomic frenzy which led to numerous species being described from different localities (Taylor 1965). After three subspecies from the Philippines were elevated to species status (Leviton 2014), only three subspecies remained, with C. intestinalis lineata being the only one inhabiting Singapore (Golay et al. 1993).
Calliophis intestinalis was first reported from Singapore by Cantor (1839a) who described it as a new species, Elaps furcata (Table 1). Sworder (1923) found C. intestinalis common in Singapore, and it was collected frequently early on (Peters 1859; Blanford 1881; Sclater 1891a; Boulenger 1896). Although Blanford (1881) examined specimens at the Raffles Museum, Ridley (1899) indicated that there were no specimens during his time in Singapore. As ZRC.2.3978 was collected on 11 May 1899 and ZRC. 2.4007 in June 1899, these must have been after Ridley (1899) already published his checklist. Flower (1896) recounted collecting two specimens from Tanglin, and Buddle (1929) collected one at SNB. LKCNHM has specimens from 1932, 1941, and 1948, and Cross (2020n) recorded several specimens in 1944 and 1945, but C. intestinalis was only next reported 32 years later (Table 2) by Harman (1961). Shortly thereafter, Meers (1968) described a snake bite suffered by one military personnel from a C. intestinalis. After Lim & Lim (1988b) reported a dead specimen at SRF from 16 July 1988, C. intestinalis was reported numerous times up to the publication of Teo & Rajathurai (1997). Also after that time, numerous specimens were deposited at LKCNHM. Yet, Baker & Lim (2012) classified C. intestinalis as rare. Certainly, C. intestinalis is uncommon due to its secretive lifestyle, but given the number of reported records and personal observations, we do not consider it so rare. Recent reported observations include one found in a garden at NUS Kent Ridge on 21 September 2005 (Fig. 22A) (Lim 2014b), four records from PT (Lim et al. 2016), a carcass found in a phytotelma at WNP on 20 April 2017 (Butler 2017c), a record from Alexandra Woodlands (Ho et al. 2019) and records from KRP and NUS Kent Ridge (Tan et al. 2019).
