Bauer (2018) it is likely that the names Euprepes olivieri var. albo-punctatus Bocage, 1867 and 
Euprepes angolensis Bocage, 1872 apply to this clade. Boulenger (1887) and Bocage (1895a, 
1896a) incuded both in the synonymy of varia. The original description of albopunctata is consis¬ 
tent with the morphological characters of members of the Angolan clade, and given its precedence, 
we tentatively recognize it as the name applicable to varia-XikQ Trachylepis in Angola, exclusive of 
the southeast. Euprepis angolensis, which we consider as a probable junior synonym of T. albop¬ 
unctata has been considered by some to refer to the same species as Mabuia striata angolensis 
Monard, 1937 (see Trachylepis monardi account). Unfortunately, all of the original Bocage speci¬ 
mens associated with this name were destroyed, exacerbating the task of trying to link this name 
with particular specimens in the T. varia complex. It is likely that some of the older literature 
records may refer to other species of Trachylepis outside the T varia complex, so our assessment 
of the distribution of this group in Angola should be interpreted as a rough estimate at best. 
A review of the Angolan Trachylepis being prepared to resolve this and other similar problems.

Mabuya bayonii huilensis (Laurent 1964a:67). Holotype: MD 1886 (collector A. Barros Machado). Type loca¬ 
lity: “Boca de Humpata, environs de Sa da Bandeira, Huila” [= Humpata], Huila Province, Angola.

Traehylepis bayonii: Menegon and Spawls (2011), Ceriaco et al (2016b:57). 
Global conservation status (lUCN): Data Deficient. 
Global distribution: The species has been reported from Angola, the Democratic Republic of 
Congo, and Kenya and Tanzania, although the East African forms are referable to T b. keniensis 
(Loveridge, 1956) and are almost certainly specifically distinct from the West African T b. bayonii 
and T b. huilensis. 
Ocurrences in Angola (Map 217): The species mainly occurs in central Angola and south¬ 
western Angola. Zaire: “S. Salvador do Congo” [-6.26667, 14.23333] (Bocage 1887a: 179,
