La présente étude a pour objectif d'inventorier les scorpions de la région de Tiaret qui se situe au nord-ouest de l'Algérie d'une part, et d'autre part d'établir les modèles de répartition de chaque espèce. Durant deux ans de prospection entre 2021 et 2022, plus de 467 spécimens de scorpion ont été collectés, repartis en 17 espèces appartenant à cinq genres (Androctonus, Buthacus, Buthiscus, Buthus et Scorpio) et groupées en deux familles (Buthidae et Scorpionidae). La famille des Buthidae est la plus représentée avec 14 espèces dont 5 espèces endémiques de l'Algérie. Par contre, la famille des Scorpionidae renferme seulement 3 espèces avec une espèce endémique en Algérie. Le résultat relatif à l'abondance relative (AR %) montre quel'Androctonus australis est le plus abondant avec une valeur de 22,06 % contre 5,78 % de celle deScorpio maurus. L'indice de Shannon est estimé à 1,57 bits et témoigne d'un niveau élevé de diversité scorpionique dans la région d'étude (Tiaret). Il est à signaler que l'inventaire que nous avons dressé constitue une étude pionnière sur les scorpions dans cette importante région qui abrite plus de 31% des espèces scorpioniques algériennes et réuni plusieurs espèces signalées pour la première fois dans cette région.
Abstract The present study aims to inventory the scorpions of the region of Tiaret which is located in the northwest of Algeria on the one hand and on the other hand to establish the distribution patterns of each species. During two years of prospecting between 2021 and 2022, more than 467 scorpions were collected, divided into 17 species belonging to five genera (Androctonus, Buthacus, Buthiscus, Buthus and Scorpio) and grouped into two families (Buthidae and Scorpionidae). The Buthidae family is the most represented by 14 species of which 5 species are endemic to Algeria. On the other hand, the Scorpionidae family contains only 3 species with an endemic species in Algeria. The result of the relative abundance (RA%) shows that Androctonus australis is the most abundant with a value of 22.06% against 5.78% of that of Scorpio maurus. Shannon's index is estimated at 1.57 bits, indicating a high level of scorpion diversity in the study region (Tiaret). It should be noted that the inventory that we have drawn up constitutes a pioneering study on scorpions in this important region Arachnides 109, 2023 2 which contains more than 31% of Algerian scorpion species and brings together several species reported for the first time in this region.
... Scorpion fauna of Algeria are truly native, and the endemic species represent more than 59% [40,41]. More than 49 species can be found [42,43], and the species are assembled in three major groups: scorpions of Algerian-Tunisian compartment (Mediterranean area), those of Saharan sector and scorpions of Saharo-mountainous sector [44]. ...
... Most of those species are recorded as Saharan endemic scorpions [40,44,71]. In neighboring regions of Ghardaïa, [72] identified eight scorpions species in El-Oued and nine scorpion species in Ouargla, [40]. ...
... Most of those species are recorded as Saharan endemic scorpions [40,44,71]. In neighboring regions of Ghardaïa, [72] identified eight scorpions species in El-Oued and nine scorpion species in Ouargla, [40]. In the Algerian forest and mountainous ecosystems, up to ten scorpion species were identified in Sidi Bel Abbes, northwest Algeria [73] and eight scorpion species were identified in the Ouarsenis massif of Tissemsilt, northwest Algeria [23]. ...
In desert ecosystems, arthropods such as scorpions are understudied, and sufficient information is still lacking regarding their biodiversity. Specimen collection was carried out over 24 months (2016–2017). This study assessed the phenology, abundance, richness and diversity of scorpion species in arid ecosystems of the Sahara desert of Algeria (Ghardaïa). It examined the potential influence of climate parameters (precipitation, temperature and wind) on activity density, diversity
and the phenological distribution of the species among seasons. We identified eight Buthidae species: Androctonus aeneas, Androctonus amoreuxi, Androctonus australis, Buthacus samiae, Buthacus spinatus, Buthacus elmenia, Buthus saharicus and Lissothus chaambi. Androctonus amoreuxi and Androctonus australis were the most abundant and omnipresent species, comprising 54.41% and 33.82% of all
species found, respectively. Shannon’s index and the evenness index demonstrated a very poor diversity of scorpions in this region and a poor balance between the number of sampled species. Seasonal variation and climate parameters, i.e., temperature and wind, influenced the number, distribution, and the diversity of scorpions. The number of species found in Ghardaïa Province represent more than 20% of the scorpion species reported in Algeria.
... In Algeria, it is classified as quite rare, limited to "reg" (rock gravel) and palm groves (Sadine et al. 2011;Sadine 2012;Sadine et al. 2020). Its geographical distribution ranges from Central Algeria in the West to northwestern Libya in the East (Lourenço 2002;Goyffon et al. 2012;Sadine 2012;Sadine et al. 2018;Aboshaala et al. 2020). In the Misurata region, we found this species in sandy habitats with a sparse vegetation cover. ...
... Cain et al. (2021) reported that scorpions of the genus Buthacus are commonly known as "sand scorpions". In central Algeria, all Buthacus species were captured in Erg biotopes (Lourenço and Sadine 2015;Lourenço et al. 2016Lourenço et al. , 2017aSadine et al. 2018) or in sand deposits (Lourenço et al. 2017b). We note here that vegetation cover, precipitation and elevation apparently have no effect on Buthacus species. ...
The scorpion fauna of Libya is varied and endemic, but little explored. Our work is a contribution to the study into the ecology and distribution patterns of scorpions from the Misurata region (North Libya). Investigations were carried out at 12 sites between June 2019 and December 2020 using ultraviolet light. We sampled 96 adult specimens belonging to nine species: Androctonus amoreuxi (relative abundance “RA” = 2.08%), Androctonus australis (RA = 31.25%), Androctonus bicolor (RA = 9.33%), Buthacus arenicola, Buthacus sp. 1 and Buthacus sp. 2 (RA = 3.13%), Buthiscus bicalcaratus (RA = 10.42%) Buthus adrianae (RA = 18.75%) and Buthus orientalis (RA = 19.79%). This region is characterized by great scorpion diversity and high community evenness.
Among the specimens belonging to the above-mentioned nine species, we noted two species of Egyptian Buthus: B. adrianae and B. orientalis, representing a new record for Libya, and classified as a very accidental species (Occ = 50%). By frequency of occurrence, the other species were assigned to different categories ranging from very accidental to the common ones. The Canonical Correspondence
Analysis (CCA) performed to detect gradients in species composition and species-environment relations confirmed the existence of a close relationship between some species and their biotopes, i.e., scorpions of the genus Buthacus were associated with sandy habitats, while A. amoreuxi and A. australis were associated with desert conditions (scarce vegetation, low precipitation and elevation). However, the ecological preferences of B. bicalcaratus remain uncertain.
... 1). In many studies, this species was reported in Algerian Northern Sahara (Sadine et al., 2011;Sadine, 2012Sadine, , 2018bSadine et al., 2018), while Lourenço (2006) mentioned this species in Biskra region (North east of Algeria). In our study area, Vachon (1952) has examined a scorpion material from the El-Goléa region and Sadine et al. (2014) cited this species in Erg and sandy Regs of Ghardaïa (central Algeria) (Fig. 7A). ...
... The species was described from Ghardaïa Erg. It was recently found in Ouargla Erg, more than 200 km east of the type locality (Sadine et al., 2018). In this work, B. samiae expanded its range to the south of our study area and it was found in co-habitation with B. elmenia, while, it cohabits with B. spinatus in the North. ...
The genus Buthacus Birula, 1908 (Family Buthidae) regroups about 30 species commonly known as sand scorpions. In the Algerian sandy deserts, in particular, this group shows a micro-endemic populations. The present paper summarizes the exhaustive list of Buthacus species in Ghardaïa region (Central Algeria), basing on sampling period of 12 months (2021). As a preliminary result, five species were recorded from the study area: B. arenicola, B. birulai, B. elmenia, B. samiae, and B. spinatus. Of which, two species are original from Algerian Eastern Erg (B. arenicola and B. birulai) while, the other species were recently identified from Ghardaïa region. All these species show a close affinity to Erg or sandy biotopes except B. samiae which presents a wide distribution in study area and in sandy Reg. Also, it has the ability to cohabit with other Buthacus such as B. spinatus in the North and B. elmenia in the south.

... The geographical distribution of this species extended across North Libya, Tunisia, Algeria and north-eastern part of Mali (Birula, 1905;Pallary, 1937;Vachon, 1941;Sadine et al., 2011;Goyffon et al., 2012;Sadine, 2018;Sadine et al., 2018;Lourenço, 2002;Aboshaala et al., 2020;Sadine et al., 2020). ...
The monotypic genus Buthiscus was described by Birula (1905) with the species Buthiscus bicalcaratus from the Sahara Desert of southern Tunisia. Until now, huge gaps exist in the knowledge of this species which is classified as endemic to North Africa. This paper aims to enrich the existing knowledge on this poorly known species with redescribing specimens of both sexes collected from Libya using widely illustrated redescription, in light of modern standards ruling the taxonomy of scorpions.
... Historically, most of the existing literature is Vachon (1952), El-Hennawy (1992), Sadine et al. (2018) and other similar contributions to the Algerian scorpion fauna are based on morphological and morphometric studies. However, the phylogeny and DNA barcoding of identified species have never been investigated, except for some general attempts focusing on the Maghreb Buthus gene (Sousa et al., 2012;Pedroso et al., 2013;Klesser et al., 2021). ...
... This group is ranked as a sister clad to the clad which includes three sequences (MT955934, MT955935, MT955936) (mOTU 18) that were sampled from Tell Atlas Mountains in Tunisia (Ain Draham) (Klesser et al., 2021). This result shows that Buthus tunetanus occupies a large area from the Tellian Atlas through the Saharan Atlas to the beginning of the northern Sahara (Vachon, 1952;Gantenbein & Largiadèr, 2003;Kovařík, 2006;Sadine et al., 2018;Ouici et al., 2020). Furthermore, the distribution of these sequences into two subclades is confirmed by Klesser et al. (2021). ...
The genus Buthus Leach, 1815 is the most diverse and the most widespread scorpion genus in family Buthidae C.L. Koch, 1837. In the last two decades, an impressive number of publications have demonstrated remarkable progress in the number of Buthus species in Algeria, which has risen to ten species. The taxonomic status of the genus based on morphologic keys, deserves to be elucidated with an exhaustive list of species as taxonomic reference including dichotomous keys and genetic barcodes.
In this paper, a genetic study of Buthus species complex from Aures region (eastern Algeria) has been performed based on DNA barcoding. In addition, a multi-rate Poisson tree process (mPTP) and Assemble Species by Automatic Partitioning (ASAP) methods were used to generate molecular species descriptions of 229 COI sequences. The morphological results lead to the description of two Buthus species in our study area:
Buthus aures Lourenço & Sadine, 2016, and Buthus tunetanus (Herbst, 1800). Among the
important results is the confirmation of the morphological identification of two Algerian
401
Buthus species (B. aures and B. tunetanus) by the genetic identity. Furthermore, 22 molecular operating taxonomic units (mOTUs) were suggested by mPTP method, where
eight mOTUs are distributed all over Algeria, of which Aures region includes four of them. In addition, according to literature data, the number of existing Buthus species and their geographical distribution patterns in Algeria are discussed.
... Many recent works of Sadine and his co-authors proved the existence of this species in several localities in Septentrional Sahara of East Algeria (Sadine, 2005;Sadine et al., 2011;Sadine, 2012;Sadine, 2018;Sadine et al., 2018). Although, , Lahrech & Souilem (2017), Sadine (2018), and Bengaid (2018) indicated the absence of this species in central of Algeria (Ghardaïa). ...
... Because it prefers shady and humid area. This species is ranged as hygrophilous species (Sadine, 2005;Sadine, 2012;Sadine, 2018;Sadine et al., 2018). However, in Morocco, O. innesi is limited to areas with loamy, clayey soils (pelophilous species), sandy, and earthy habitats. ...
... In Algerian Septentrional Sahara, this species is represented with abundance less than 5% in the palm groves of East Algeria (Sadine, 2005;Sadine et al., 2011;Sadine, 2012;Sadine, 2018;Sadine et al., 2018). Contrariwise, this species, was not reported in central of Algeria, especially in Ghardaïa Lahrech & Souilem, 2017;Sadine, 2018;Bengaid, 2018). ...
This note concerns a small scorpion and a little-known buthid species Orthochirus innesi Simon, 1910. According to the last work about scorpions of Algeria in 2018, this species is located in Algerian Septentrional Sahara at the East of Algeria. This finding provides a new locality of O. innsi outside this geographical distribution range, of which it is extended about 200 km to the central of Algeria (Ghardaïa). This new locality is a palm groves of Zelfana, confirming that O. innesi from Algeria has an affinity to shady and humid area.
... Since the general contribution of Vachon (1952) and El-Hennawy (1992) on scorpions from North Africa, some new contributions focused on scorpions of Algerian Sahara (Lourenço, 2002;Sadine, 2005;Lourenco & Leguin, 2011;Sadine et al., 2011;Sadine, 2012;Sadine et al., 2014;Lourenço & Sadine, 2014;Sadine et al., 2016;Lourenço et al., 2017a;Lourenço et al., 2017b;Lourenço et al., 2018a;Sadine, 2018;Sadine et al., 2018) and in the North-east of Algeria such as in Batna and M'Sila Lourenço et al., 2018b). But in North-west Algeria, all works are very old like the note about Androctonus aeneas (Koch, 1839) and Scorpio maurus trarasensis Bouisset & Larrouy, 1962 in Oran region. ...
Our work is a recent exploration of North-west of Algeria and a preliminary study on the scorpion fauna of Sidi Bel Abbes region. From different biotopes (Steppe, Forest, and Matorral) and during 12 months of 2019, we sampled 90 specimens of scorpions belonging to 10 species under 3 genera distributed in 2 families. The family Buthidae is represented by Androctonus aeneas (relative abundance “RA”= 2.22%), Buthus boussaadi (RA= 14.44%), Buthus oudjanii (RA= 3.33%), Buthus paris (RA= 16.67%), Buthus pusillus (RA= 3.33%), Buthus tunetanus (RA= 38.89%), and a new Buthus species (RA= 6.67%). The family Scorpionidae is represented by Scorpio maurus (RA= 8.89%), Scorpio maurus trarasensis (RA= 2.22%), and Scorpio punicus (RA= 3.33%). Among the important results in this work is a new record of Moroccan scorpion B. oudjanii Lourenço, 2017 in Algeria and reporting the presence of two scorpion species B. boussaadi and B. pusillus known from the North-east of Algeria. The Shannon’s index (H’ = 2.67 bits) indicates that Sidi Bel Abbes region has a high level of scorpion diversity and the value of evenness (E = 0.80) reflects the high equilibrium between the effectiveness of sampled species. There is a close affinity between some species and their biotopes such as A. aeneas has an affinity to herbaceous habitats, B. boussaadi was closely attached to medium altitude (500-800 m) and B. oudjanii probably prefers the forest with Mediterranean climate, high altitudes (1600 m) and with common forest species such as Quercus ilex and Pistacia lentiscus.
