In an historical context, Morocco has been suitably explored
with herpetological expeditions dating back to Gervais (1835).
The distribution of amphibians and reptiles in Morocco is thor-
oughly outlined in the herpetofaunal atlas by Bons and Geniez
(1996); this atlas is used as a primary reference in this paper. The
following is a composite of significant findings from five months
of data gathered in southern Morocco during the periods of May–
July 1985, October 1999, and September–October 2000. Such has
resulted in notable range extensions for six species of lizards and
three species of snakes and several novel comments on natural
history. Voucher specimens were deposited in the Zoologisches
Forschungsinstitut und Museum Alexander Koenig (ZFMK),
Bonn, or the Hessisches Landesmuseum (HLMD), Darmstadt,
Germany. Localities were determined by the use of a handheld
Garmin© global positioning system (GPS) device or by the use of
maps. Specimen identification relative to range extensions were
confirmed by Wolfgang Böhme, Zoologisches Forschungsinstitut
und Museum Alexander Koenig, Bonn.
Anura
Bufo brongersmai – Tafraoute, 29°43.30’N, 8°58.76’W, 11 Octo-
ber 1999. At ca. 2100 h hundreds of animals were encountered in
the flat-packed sand basin between the rocky hills adjacent to the
town. The toads were active and orienting apparently at random,
along with equally abundant Bufo viridis and numerous Bufo
mauritanicus. This was after the second day of heavy rain follow-
ing what locals reported as a two-year drought. No amplectant
pairs were observed. No standing water was encountered. In
Tafraoute on 18 June 1985, during the dry summer period, only
one toad was found. It was located at night under plants which
were routinely watered and was within the town limits. On 9 and
10 October 2000, two nights of searching at the Tafraoute locality
revealed no toads. This was also during an extended dry period.
This illustrates the periodic abundance of this reportedly rare toad
species (Bons and Geniez 1996).
Lacertilia
Stenodactylus petrii – Oued Tissinnt, ca. 5 km E of Mrhimina,
29°49.14’N, 7° 08.18’W, 5 October 2000. This area is character-
ized by low-lying sand dunes interspersed with lava flows and
large lava boulders. Two specimens were collected while search-
ing the Oued Tissinnt dunes at night (ZFMK 73504: SVL 50 mm,
TL 97 mm; ZFMK 73505: SVL 38 mm, TL 72 mm). This find
extends the range of this species by ca. 100 km to the west and is
the first reported locality away from major sand dunes. Dry river-
bed routes may be used by this psamnophilous species as dispersal
pathways.
Stenodactylus sthenodactylus – Tendrara, ca. 9 km N of the town,
33°05.05’N, 1°59.27’W, 4 October 1999. This male specimen
(ZFMK SA2001:1) was found during the day, in a flat, hard-packed
sand desert, under a rock. This find extends the eastern range of
this species by ca. 50 km in Morocco, thus bringing it to the Alge-
rian border.
Ptyodactylus oudrii – Oued Tissinnt, ca. 5 km E of Mrhimina,
29°49.14’N, 7°08.18’W, 5 October 2000. This gecko is cited in
the literature as a dweller of steep and smooth rocks, boulders,
and cliffs (Bons and Geniez 1996; Schleich et al. 1996). Here we
report the use of a tree as a habitat for this species. A night search
revealed two specimens ca. 1.6 m above ground in an Acacia tree.
Ants, which are a prey item of this species, were also active on the
tree at this time. The immediate surrounding habit was low-lying
sand dunes with occasional volcanic rocks. In the distance, larger
rock formations could be found.
Tarentola hoggarensis – Oued Drâa, ca. 20 km S of Âouïnet-
Torkoz, 28°29.00’N, 9°51.17’W, 4 October 2000. This species has
a lengthy and involved history of taxonomic revision (Schleich et
al. 1996). Due to recent findings within the Tarentola ephippiata
group, the taxon should be elevated from subspecific status of
Tarentola ephippiata hoggarensis to full species rank (Böhme et
al. 2001; Böhme, pers. comm.). This Oued Drâa specimen (ZFMK
73503) was found by torchlight at night on an Acacia tree trunk.
This find represents the third discovery of this species in Morocco
and is ca. 50 km east of a previously documented locality (Bons
and Geniez 1996).
Lacerta andreanszkyi – Imlil, ca. 5 km NE of town, 5 July 1985.
The discovery of this specimen (ZFMK 44116) at an alpine
meadow at ca. 2400 m elevation confirms its presence in a ques-
tionable locality as listed in Bons and Geniez (1996).
Acanthodactylus boskianus – Taroudant, ca. 3 km S of town, 25
May 1985. This species is known to be an inhabitant of dry envi-
ronments (Bons and Geniez 1996; Schleich et al. 1996). The dis-
covery of this specimen (ZFMK 44079) resting underneath some
small bushes marks its first known occurrence in a relatively moist
habitat, the Souss River Valley. This report contrasts the findings
of Bons and Geniez (1996) whereby they state that A. boskianus
is absent from the western parts of Morocco, as the Anti Atlas
appears to constitute an insurmountable barrier. This finding shows
the species to have crossed the Anti Atlas, although the westernmost
portion of the Haut Atlas lies due north as a border of this locality.
This find is ca. 80 km from the nearest documented locality, though
more significantly, it places the species for the first time on the
north side of a significantly high mountain range.
Mesalina olivieri – Oued Torkoz – Oued Drâa confluence,
28°29.00’N, 9°51.17’W, 3 October 2000. The discovery of these
specimens (ZFMK 73511–512) confirms a suspected locality (Bons
and Geniez 1996) in the Oued Drâa. This population is ca. 120 km
from the closest confirmed population. Some authors (e.g., Le Berre
1989) regard Mesalina pasteuri (Bons 1960) and olivieri, both
taxa are reported from Southern Morocco (Bons and Geniez 1996),
as conspecific.
Eumeces algieriensis – Tafraoute, 20°43.30’N, 8°58.76’W, 22
September 2000. The diet of this large endemic Mograbin skink
consists of invertebrates (Schleich et al. 1996). After hand capture,
our specimen regurgitated a gecko which, although partially
digested, could be identified as a Tarentola mauretanica.
Serpentes
Leptotyphlops macrorhynchus – Amtoudi (Id-Âïssa), 29°13.66’N,
9°13.24’W, 11 June 1985. This specimen (ZFMK 44098) was
found in an area lacking vegetation within this oasis village. Though
suspected to be a wideranging species in Morocco, secrecy and
subterranean habits have surely restricted this species from being
routinely encountered and is thus far listed from but ten localities.
This discovery in the southern Anti Atlas foothills represents a
distance of ca. 80 km from the closest documented record.
Macropodon cucullatus – Plage Blanche, 28°57.73’N, 10°32.89’W,
28 September 2000. According to Bons and Geniez (1996), M.
cucullatus is represented by three subspecies in Morocco. The Plage
Blanche specimen (ZFMK SA2001:2) keys out to the subspecies
brevis according to head coloration (Schleich et al. 1996; Wade
1988). Our specimen falls within a ca. 160 km gap between the
ranges of the subspecies cucullatus and brevis.
Bitis arietans – Plage Blanche, 28°57.73’N, 10°32.89’W, 117 m
elevation, 28 September 2000. A ca. 90 cm adult female gave birth
two days after capture to eight live and two dead neonates,. This is
a very small litter size as this species is known to commonly have
litters of 20–30 with litters of up to 50–60 not being rare (Schleich
et al. 1996). Bitis arietans from southern Morocco, however, are
known to be much smaller in size than their tropical conspecifics.
Echis leucogaster – Oued Torkoz – Oued Drâa confluence,
28°22.00’N, 9°50.00W’, 120 m elevation, 19 October 1999. This
is one of the rarest of Moroccan snakes (Bons and Geniez 1996),
and although known from the Oued Drâa, ours is only the fifth
Moroccan specimen (Herrmann and Herrmann 2000). Adult fe-
male (SVL 41 cm, TL 44.5 cm) (HLMD RA2888) was found dead,
killed by bedouins, and hanging in a bush.
