been in continuous use for over a century, Boundy (2014) argued that the former name should be 
treated as a nomen oblitum and the later as a nomen protectum, although he did not use those terms. 
Although Boundy (2014) invoked Article 11 of the International Code of Zoological Nomenclature 
to support his interpretation of the availability of Peters’ name for this taxon, we disagree. Article 
11.5 states “To be available, a name must be used as valid for a taxon when proposed, unless it was 
first published as a junior synonym and subsequently made available under the provisions of Arti¬ 
cle 11.6.1.” As S. scutatum was first proposed as a synonym and was not treated as an available 
name prior to 1961, it is unavailable under the Code. Bauer et al. (1995) incorrectly included 
“Benguella [Angola] (Westafrika)” as part of the type locality for S. scutifrons (Bauer et al. 2002). 
Adalsteinsson et al. (2009), transferred latifrons to the new genus Namibiana. It is possible that 
some specimens from western Angola currently assigned to Leptotyphlops scutifrons may represent 
this species, and such material should thus be carefully rexamined.

Stenostoma rostratum: Bocage 1886a: 173. Holotype: MBL specimen number unknown (collector J. d’Anchi¬ 
eta), destroyed by fire 18 March 1978. Type locality: “envoye du Humbe, sur les bords du Cunene” 
[= Humbe] Cunene Province, Angola. 
Stenostoma rostratum: Bocage (1895a:71, 1897a: 199).

Global conservation status (lUCN): Data Deficient. 
Global distribution: The species is endemic to Angola. 
Ocurrences in Angola (Map 263): The 
species is known from western portions of the 
country, from the type locality, “Humbe” north 
to “Luanda.” Malanje: “Vana e Lumbe” 
(Broadley and Broadley 1999:18). Luanda: 
“Luanda” [-8.83333, 13.26667] (Broadley and

[-15.05000,13.55000] (Broadley and Broadley 
1999:18). Cunene: “envoye du Humbe, sur les 
bords du Cunene (Humbe)” [-16.68333,

1897a: 199; Broadley and Broadley 1999:18;

Locality: “without precise location” (Bocage

new data for the species in Angola, increasing the distribution range further north from the type 
locality. The generic map for Namibiana provided by Adelsteinsson et al. (2009) shows no species 
occurring north of Kwanza Sul.
