A New Lithophilic Compsobuthus Vachon, 1949 (Scorpiones: Buthidae) From Northern Oman, Graeme Lowe
A New Lithophilic Compsobuthus Vachon, 1949 (Scorpiones: Buthidae) From Northern Oman, Graeme Lowe
Euscorpius
A new species of Compsobuthus is described from the Al Hajar mountains of northern Oman. It is distinguished by a strongly dorsoventrally compressed body, reduced carination on the carapace and tergites, extreme elongation of legs and pedipalps, lack of external accessory denticles on the pedipalp fingers, chelal trichobothrium est placed closer to dt than db, heavy setation on the ventral metasoma, and 28–34 pectine teeth. It is an ultralithophilic scorpion, highly adapted to life in narrow rock fissures.
Two New Hemiscorpius Peters, 1861 (Scorpiones: Hemiscorpiidae) From Northern Oman, Graeme Lowe
Two New Hemiscorpius Peters, 1861 (Scorpiones: Hemiscorpiidae) From Northern Oman, Graeme Lowe
Euscorpius
Two new species of Hemiscorpius, H. falcifer, sp. nov. and H. flagelliraptor, sp. nov., are described from the Al Hajar Mountains of northern Oman. Although both are lithophilic or ultralithophilic scorpions beautifully adapted for living in rock crevices, they exhibit divergent morphologies and may not be closely related. H. falcifer is distinguished by: smaller size, relatively short compact metasoma, bulbous telson, relatively distal placement of lamellar double hook of hemispermatophore, pedipalp chela with wide, sub-triangular manus and exceptionally elongated fingers with single file dentition along distal half of movable finger (in adults); H. …
New Picobuthoid Scorpions (Scorpiones: Buthidae) From Oman, Graeme Lowe
New Picobuthoid Scorpions (Scorpiones: Buthidae) From Oman, Graeme Lowe
Euscorpius
Five new species of diminutive buthid scorpions are described from Oman. Two belong to Microbuthus Kraepelin, 1898, a genus with heavily sclerotized, smooth, strongly pitted posterior metasomal segments, abbreviated telson, and pedipalps with 9 femoral and 6–7 external patellar trichobothria: M. gardneri, sp. nov., from the Al Hajar Mountains, and M. kristensenorum, sp. nov., from the Dhofar Mountains and Hadhramaut of Yemen, which was long misidentified as M. pusillus Kraepelin, 1898. Two additional new species are placed in a new genus Picobuthus, gen. nov., differentiated by granular posterior metasomal segments, elongate telson, pedipalps with …
A New Species Of Odontobuthus (Scorpiones: Buthidae) From Northern Oman, Graeme Lowe
A New Species Of Odontobuthus (Scorpiones: Buthidae) From Northern Oman, Graeme Lowe
Euscorpius
The Asian buthid genus Odontobuthus is newly recorded from the Arabian Peninsula where is represented by O. brevidigitus sp. nov. from the Batínah coast and foothills of the Al Hajar mountains of northern Oman. The new species is characterized by short pedipalp fingers, long pectines with narrow basal middle lamella, 2–3 enlarged denticles on ventrosubmedian carinae of metasoma II–III, stout metasoma IV with 10 anterior transverse granules, 3 lateral anal lobes, and enlarged dentition on the ventral anal arch. A model is proposed for the speciation of Odontobuthus by westward dispersal of an ancestral population on the Indus floodplain, …
