material under that account. As both names are currently placed in the same genus Monard’s name 
is a junior secondary homonym of Bocage’s. As such Bocage’s name, despite being a junior sub¬ 
jective synonym of Trachylepis varia, must retain the epithet angolensis, and Monard’s name 
requires a replacement (the special conditions of Article 23.9 do not apply as an insufficient 
number of citations by an insufficient number of authors have used Monard’s name). As no junior 
synonyms are known to exist for Trachylepis angolensis (Monard, 1937) we propose Trachylepis 
monardi nom. nov. as a replacement name, in recognition of the contributions of Albert Monard 
(2 September 1886 - 27 September 1952), Swiss naturalist from La Chaux-de-Fonds, who under¬ 
took two major expeditions to Angola and left a legacy of specimens and published papers relating 
to the zoology of not only Angola, but also Cameroon, Guinea-Bissau and North Africa. Monard 
(1937b) noted 26 syntypes in the type series. Fifteen of these remain in La Chaux- 
de-Fonds. Ortiz (1989) cited MHNN (Museum d’histoire naturelle de Neuchatel) 2130 as the 
lectotype, giving both localities “Kuvangu” and “Bimbi”. The MHNC specimens thus are paralec- 
totypes, as is the single Geneva “paratype” cited by Mahnert (1976) and Schatti and Ferret (1997), 
for which the locality is also uncertain. Monard typically dispersed specimens to the many Swiss 
institutions that helped sponsor his field work, including high schools. It is likely thjat the “miss¬ 
ing” nine specimens were or are in such small collections. 
Trachylepis occidentalis (Peters, 1867) Western Three-Striped Skink 
Euprepes vittatus var. australis Peters 1862a: 19. Syntypes: ZMB 4212, 64401-02 (formerly ZMB 4212A-B) 
(eolleetor C.H. Hahn). Type loeality: “Neu-Barmen” [= Gross Barmen, Otjozondjupa Region] Namibia by 
implieation fide Bauer et al. (1995, 2003). 
Euprepes oeeidentalis Peters 1867:20, replaeement name for E. v. australis Peters 1862, preoeeupied by 
Euprepes australis Gray, 1838 [= Ctenotus australis (Gray, 1838 “1839”)]. 
Euprepes oeeidentalis: Boeage (1870:68). 
Mabuia oeeidentalis: Boeage (1895a:42). 
Mabuya oeeidentalis: Laurent (1964a:73), Braneh (1998:156), Broadley (2000:97). 
Traehylepis oeeidentalis: Bates et al. (2014:263), Ceriaeo et al. (2016a:33, 57). 
Global conservation status (lUCN): Not 
Evaluated. 
Global distribution: Distributed from 
arid western South Africa and southwestern 
Botswana through Namibia to arid areas of 
southwestern Angola. 
Ocurrences in Angola (Map 228): The 
species distribution is limited to the desert 
regions in Namibe Province. Namibe: 
“Mossamedes desert, 35 km south from the 
city” [-15.50575, 12.20768] (Laurent 1964a: 
73; Ceriaeo et al. 2016a;57); “Rio Coroca” 
[-15.78333, 12.06667] (Boeage 1895a:42; 
Ceriaeo et al. 2016a;57); “Pico Azevedo” 
[-15.53400, 12.49197] (Ceriaeo et al. 
2016a:33). 
Taxonomic and distributional notes: 
Bauer et al. (2003) also included ZMB 4213,
