Belongs within: Scorpionoidea. Australia’s own scorpions Published 23 September 2023 Popular lore represents the continent of Australia as some sort of death world, a land over-run with creatures (and a few plants) whose only goal in life is the extermination of unwitting trespassers within their demesne. This, of course, is largely rubbish; in most parts… Continue reading Urodacus


Belongs within: Chactoidea.Contains: Urodacus. The Scorpionoidea are a clade of scorpions characterised by katoikogenic development. Females produce small eggs with no yolk or embryonic membranes whose embryos are nourished via attachment of the embryonic chelicerae to modified outgrowths of the ovariuterus (Sharma et al. 2015). Members include the pantropical Hormuridae which have a low median… Continue reading Scorpionoidea


Belongs within: Iurida. The Bothriuridae is a group of scorpions found in Australia and South America characterised by legs with two pedal spurs, a vertically compressed sternum, and pedipalps with chelal trichobothrium Et2 on the ventral surface and ib at the extreme base of the fixed finger or on the palm. Bothriuridae [Bothriuroidae, Bothriuroidea] |–VachonianinaeK77… Continue reading Bothriuridae


Belongs within: Buthoidea. The Buthinae are a pantropical group of scorpions with oblique, non-overlapping rows of tooth-like granules on the movable finger of the pedipalp. The genus Isometrus is found primarily in the Old World tropics, except for the pantropical I. maculatus. The world’s scorpion Published 14 July 2014 With their elongate, sting-tipped tails, scorpions… Continue reading Buthinae


Belongs within: Orthosterni.Contains: Microtityus, Buthinae, Tityus. The Buthoidea are a group of scorpions that lack ventral trichobothria on the patella of the chela (Soleglad & Fet 2001). Members are currently divided between the cosmopolitan Buthidae and the Madagascan Microcharmidae though it has been suggested that the latter represents a subgroup of the former. <==Buthoidea |–MicrocharmidaeSF01… Continue reading Buthoidea

Belongs within: Euchelicerata.Contains: Orthosterni. The Scorpiones, scorpions, are a highly distinctive group of arachnids in which the pedipalps form large chelae and the rear section of the opisthosoma is modified to form a mobile ‘tail’ bearing a terminal sting. Modern scorpions are invariably terrestrial but aquatic habits have been suggested for the earliest known Silurian–Devonian… Continue reading Scorpiones

Belongs within: Scorpiones.Contains: Iurida, Buthoidea. The Orthosterni is a clade including the living scorpions and some fossil relatives, characterised by the presence of trichobothria on the pedipalp (Soleglad & Fet 2001). Molecular phylogenetic analysis supports the division of living scorpions between two basal lineages, the Iurida and Buthida (Sharma et al. 2015). <==Orthosterni [Dionychopodes, Neoscorpii,… Continue reading Orthosterni
