Adult specimens reach a considerable size of about 70 mm. The overall color is uniformly yellow to yellow-reddish with darker carinae on the metasoma. The scorpion shows the typical characteristics of the genus Androctonus including slender pedipalpchelae and a thick, robust metasoma with a proportionally large vesicle (bulbous part of telson containing the venomglands). Granulation of the cephalothorax and mesosoma is slightly more pronounced in the male than in the female and the males have an excavation at the base of the fixed finger of the chelae to accommodate the females pincers during mating "dance".[1]
A. maroccanus is distinct from most of the potentially sympatric, dark-colored species of Androctonus by its brighter coloration.[1] It differs from the similar A. australis in having a strongly hirsute "fore-arm" (patella) of the pedipalps and a more reddish coloration. Furthermore, in Morocco A. australis is so far known only from the easternmost part of the country.[2] Another yellow-colored species, A. amoreuxi, occurring in the south and southwest of Morocco, is distinguished by a much slender metasoma.[3]
Toxicity
There are no data on the toxicity of this species. However, as it is the case in many other species of Androctonus,[4] the presence of very potent toxins and a potential medical importance to humans can be anticipated.
Range and habitat
A. maroccanus is known so far only from its type locality, the semi-arid coastal plain at Sidi Smaïl, c. 120 km southwest of Casablanca, Morocco. As several other of the seven species of Androctonus currently known from Morocco, it is considered endemic.[1]
