Background information.
While Moroccan presence of
S. algira
remained restricted to areas characterized by high rainfall west of the Moulouya Basin (
Pasteur & Bons 1959
), Melhaoui and Chavanon (1989) reported on a finding of a single individual on Jbel Ouartass, south of Berkane in the Beni Snassen Massif. Due to the karstic nature of this massif and presence of
S. algira
across the Algerian border near
Oran
, Melhaoui and Chavanon (1989) presumed populations of Beni Snassen to have gone unnoticed due to their nocturnal behaviour, while expecting them to be more widely dispersed across the massif. Subsequently, no additional sightings were recorded for nearly two decades, after which Escoriza
et al.
(2006) rediscovered the presence of
S. algira
in the Beni Snassen Massif. A year later,
Escoriza and Comas (2007)
described this isolated population as
S. a. spelaea
(
holotype
: MNCN 2005-05550; type locality: "Ouartass, Beni Snassen massif, Northeast-Morocco (Locality 5, at approximately
1300 m
above sea level)"). The presence of minor red discoloration on several parts of the head and body appears to be congruent with descriptions of individuals from Rhar el Maden located near Remchi, north-western
Algeria
(
Doumergue 1901
), which is situated less than
100 km
eastwards of the Beni Snassen Massif.
Natural history.
Within the
Beni
Snassen Massif,
S. a. spelaea
can be found from
600–1300 m
, occurring in the direct vicinity of water bodies which are used for reproduction (
Escoriza & Comas 2007
). Generally, populations are located in mixed forests consisting of
Quercus
,
Pinus
and
Olea
trees, characterized by an abundance of karstic limestone crevices and fissures (Escoriza
et al.
2006). Due to the nature of the soil most water bodies used for reproduction are man-made, such as cattle watering troughs or springs, although small puddles and temporary streams are also used to deposit larvae. The onset of the activity period is initiated by the late autumn rains, and continues throughout the winter. Active individuals have been observed in November during humid or rainy weather, both in the late afternoon and night. During these observations, air temperature varied between 5.8 and 7 ºC while humidity ranges between 75–85% (
Escoriza & Comas 2007
). Larvae have been found in November and January, while fully metamorphosed juveniles were observed in mid-February (
Escoriza & Comas 2007
).
Distribution.
The distribution map (
Fig. 9A
) is composed of the single record from
Bons and Geniez (1996)
. The range of
S. a. spelaea
was thought to be restricted to an area of less than
45 km
2 (
Escoriza & Comas 2007
), but is found largely continuous within (D. Escoriza pers. obs.). See also

.
National Red List Status.
Vulnerable (as part of
S. algira
).
Salamandra algira spelaea
was proposed to qualify as Endangered by
Escoriza and Comas (2007)
. The entire range of
S. a. spelaea
is subject to intensive human impact by means of logging, construction of buildings, canalization of natural springs and construction of fountains which prevent access to the limited water bodies by pregnant females. These actions have led to considerable desertification, especially on the southern slopes of the massif (
Escoriza & Comas 2007
).
