(Laurent 1964a:114). Huambo: “Bela-Vista” [-12.36667, 16.20000] (Hellmich 1957b:68); “Nova

Taxonomic and distributional notes: Although Broadley and Wallach (2002) considered 
punctatus a synonym of D. typus, Eimermacher (2012) indicated that multiple distinct lineages of 
boomslang should be probably be resurrected and elevated to species status, including D. t. punc¬ 
tatus. On this basis we list this form as a distinct taxon, but retain its subspecific status pending fur¬ 
ther data. All Angolan material should be reevaluated in order to determine where species bound¬ 
aries lie. It seems likely on biogeographic grounds that some of the more southern and western 
records previously attributed to D. t. punctatus may, in fact, belong to the nominotypical form or 
to D. t. viridis (see Notes und Dispholidus typus typus). 
Genus Grayia Gunther, 1858 
Grayia caesar (Gunther, 1863) Caesar’s African Water Snake 
Xenurophis caesar Gunther 1863:357, pi. 6, fig. c. Holotype: BMNH 1946.1.6.38 (formerly BMNH 
1843.1.10.7) (eolleetor W. Raddon). Type loeality: “Fernando P6” [= Bioko], Equatorial Guinea. 
Grayia caesar: Chippaux (2006:94), Chirio and LeBreton (2007:432), Wallaeh et al. (2014:310). 
Global conservation status (lUCN): Not 
Evaluated. 
Global distribution: The species is 
known from Cameroon, Central African to 
Democratic Republic of the Congo. 
Ocurrences in Angola (Map 346): The 
species has been recorded from the Cabinda 
enclave. Cabinda: “Mouth of the Loango” 
[-5.15000, 12.16667] (Boulenger 1894:288). 
Taxonomic and distributional notes: 
This species was only recorded from Angola by 
Boulenger (1894), this record could correspond 
to Grayia smithii (Leach, 1818), however, the 
extralimital records of G. caesar (Chippaux 
2006; Chirio and LeBreton 2007; Wallach et al. 
2014) are consistent with its occurrence in the 
Cabinda enclave.
