COMMENTS .— Psammophis notostictus is easily recognizable from all other southern African Psammophis by its single cloacal shield and the presence of two preoculars ( Broadley 1975b , 1977 , 2002 ). These two specimens have both of these diagnostic characters. The species is known for Angola , but only from Namibe Province . The closest published records of the species are in Rio São Nicolau ( Loveridge 1940 ; Broadley 1975b , 2002 ), Moçamedes [ Namibe city] ( Bocage 1887 ; Loveridge 1940 ), and Curoca River ( Loveridge 1940 ; Broadley 2002 ). Our records expand the known distribution of the species further south in the country, although it is continuous southwards throughout much of western southern Africa ( Branch 1998 ).
