al. 2016:9, 12, 14). Undetermined Locality: “Without precise location” (Bocage 1887a:191, Lau¬ 
rent 1961:88); “north of Quanza” (Bocage 1895a: 164); “Between Benguela and Bihe” (Boulenger 
1905:109); “Locomi” (Boulenger 1905:109); “plateaus regions” (Cei 1977:17); “areas of forest and 
savanna in the north and northeast of Angola” (Cei 1977:17) 
Taxonomic and distributional notes: This species was first described as Hyperolius angolen- 
sis Steindachner, 1867 based on a single specimen from “Angola,” now corrected to “Duque de 
Brangan^a” [= Calandula] (Ceriaco et al. 2014b); note, however, that Haupl and Tiedemann (1978) 
cited two syntypes from “Angola” deposited in the Naturhistorsches Museum in Wein, Austria. 
This species has been reported from Angola by many previous authors under a variety of names. 
This taxon is considered to be a synonym of Hyperolius parallelus Gunther, 1858 by some authors 
such as Wieczorek et al. (2000), Fretey et al. (2011), Ceriaco et al. (2014b), and Frost (2016). Other 
authors, including Schiotz (1999), considered it part of the Hyperolius parallelus-marginatus 
subgroup — corresponding to one of three taxa, parallelus, insignis and angolensis — or instead a 
subspecies of Hyperolius marmoratus (Rapp, 1842) as was suggested by Loveridge (1953a) and 
Poynton and Broadley (1987). Channing (2001) and Conradie et al. (2012a) comidQVQdi Hyperolius 
angolensis to be a valid species. Both H. parallelus and H. marmoratus are taxonomically prob¬ 
lematic. Poynton and Broadley (1987) regarded all the forms in southern Africa as subspecies of 
H. marmoratus, while Channing (1999) regarded angolensis and possibly other forms from Ango¬ 
la as specifically distinct from the eastern marmoratus-forms (Schiotz 1999). Hyperolius parallelus 
is represented in southern and southwestern Africa, including Angola (Schiotz 1999) whereas, 
H. marmoratus, is widespread across southern and eastern Africa and appears to be absent from 
Angola (Channing 2001; Frost 2016). The nomina parallelus and marmoratus were previously 
reported from the country under various names associated with many different species and 
subspecies names (Ferreira 1906; Loveridge 1953a; Monard 1937a, 1938; Mertens 1938; Laurent 
1964a; Perret 1976a; Fretey et al. 2011). This is explained partly by the considerable intraspecific 
and interspecific variation in coloration and pattern across populations (Ceriaco et al. 2014b). 
There are several studies in progress on the genus Hyperolius that will help to clarify species 
boundaries among these challenging taxa. Given the current state of knowledge, we refer all of 
these records to Hyperolius angolensis, though we recognize that this may contain multiple 
biological species.
