Taxonomic and distributional notes: Bocage (1873a) described Psammophylax viperinus 
based on one individual from “Dombe” collected by Anchieta in Benguela Province. Subsequent¬ 
ly he (Bocage 1895a) synonymized P. viperinus with P. nototaenia (Gunther, 1864) and recorded 
six specimens from southwestern Angola: two from “Maconjo,” one from “Capangombe,” two 
from “Humbe,” and the “Dombe” viperinus speciemen. Broadley (1997c) examined the material 
in Museu Bocage in 1968, and found only five specimens, the one from “Dombe” and two each 
from “Maconjo” and “Capangombe” (the reason for the discrepancy in the number of specimens 
from Capangombe is unknown). He suggested that the missing specimens from “Humbe” may 
have been typical H. nototaenia. However, H. nototaenia extends from Kenya to South Africa and 
Mozambique, whereas H. viperina is widely distributed from southwestern Angola to northern 
Namibia (Broadley 1990, 1997c; Broadley and Hughes 2000), suggesting that all records from 
Angola are correctly interpreted as H. viperina.
