( Figs. 1–13 ; Tab. 1 ) Type material: Morocco , trail between Assa and Aouinet Torkoz , 45 km past Assa towards Aouinet Torkoz , 12 April 2004 (W. R . Lourenço), female holotype and female paratype . Deposited in the Muséum national d’Histoire naturelle, Paris . Etymology: specific name refers to the Morocco , the country in which the new species was collected. Diagnosis Moderate sized scorpions, reaching a total length of 27 to 29 mm for females. General coloration brownish-yellow to dark brown. Anterior margin of carapace almost straight in females. Ventral aspect of metasomal segment V without granulations posteriorly. Fixed and movable fingers with 8-8 rows of denticles; accessory denticles present. Pectines with 15 to 16 teeth in females. Trichobothriotaxy: A-β (Beta) neobothriotaxy ‘minorante’ in female. Relationships: Orthochirus maroccanus sp. n. can be distinguished from the other species of Orthochirus , and in particular from Orthochirus atarensis by the following characters: (i) bigger overall size (see Table I), (ii) anterior margin of carapace almost straight in female, (iii) absence of trichobothrium d 2 of femur in female, (iv) paler coloration pattern, (v) carapace, tergites and metasomal tegument more intensely granular. Description based on female holotype and paratype . Measurements in Table 1 . Coloration. Basically brownish-yellow. Prosoma: carapace dark brown; anterior margin slightly yellowish-brown; median and lateral eyes surrounded by black pigment. Mesosoma: brownish-yellow; carinae and granulations dark brown. Metasomal segments dark brown; telson reddish-brown; aculeus reddish with a darker tip. Metasomal carinae marked with blackish. Venter yellowish-brown; pectines pale yellow. Chelicerae yellowish, with dark variegated spots; fingers brownish. Pedipalps, femur and patella brownish to brownish-yellow; chela yellowish. Legs yellowish with diffused dark brown spots. Figures 1–2: Orthochirus maroccanus , female holotype, dorsal and ventral aspects. Morphology. Carapace moderaly granular; anterior margin almost straight in female. Carinae and furrows moderate to weak. Median ocular tubercle slightly anterior to the centre of the carapace; median eyes separated by more than one ocular diameter. Three pairs of lateral eyes. Sternum subtriangular to subpentagonal, wider than long. Mesosoma: tergites with moderately marked granulations; median carina moderate in all tergites. Tergite VII pentacarinate with moderate carinae. Venter: genital operculum elongated, divided longitudinally into two suboval plates. Pectines: pectinal tooth count 15-16 ( holotype ), 15-15 ( paratype ); basal middle lamellae of each pecten not dilated. Sternites almost smooth with small slit-like spiracles; VII with four carinae moderate. Metasoma: segments rounded, with carinae moderately marked; granulations moderately marked; segments I to III with ten carinae; segments IV and V with punctuations; ventral aspect of segment V without granulations in the distal region. Intercarinal spaces with some granulations dorsally; moderately to strongly granular laterally and ventrally. Telson smooth with a few punctuations; aculeus longer than the vesicle and moderately curved; subaculear tooth absent. Cheliceral dentition characteristic of the family Buthidae ( Vachon, 1963 ) ; movable finger with basal teeth reduced but distinct; ventral aspect of both finger and manus with thin setae. Pedipalps: femur with five strong carinae, granular; patella with 6–7 moderaly marked carinae; chela without carinae, smooth. Fixed and movable fingers with 8-8 rows of denticles. Tri-
