“…However, other species are known only from their preservation in "copal" [76,135,136], thus it is possible that some of them could be found alive in the Malagasy eastern coastal forests [10,19]. Recently, Riquelme et al [137], after a study of scorpions from Miocene Mexican amber, proposed a phylogeny that included three buthid species found in "Madagascar copal"; one species was assigned to the Recent genus Microcharmus (Microcharmidae) and the rest to undetermined species in the Recent genus Palaeogrosphus [8,136,138]. They suggested that "Malagasy copal" is less than 250 years old (without explanation or new data), and that the species recognised, other than fossil or sub-fossil species, may be considered extant species.…”

Unravelling the mystery of “Madagascar copal”: Age, origin and preservation of a Recent resin

The loss of biodiversity during the Anthropocene is a constant topic of discussion, especially in the top biodiversity hotspots, such as Madagascar. In this regard, the study of preserved organisms through time, like those included in "Madagascar copal", is of relevance. "Madagascar copal" originated from the leguminous tree Hymenaea verrucosa, which produced and produces resin abundantly. In the last 20 years, interest has focused on the scientific study of its biological inclusions, mainly arthropods, described in dozens of publications. The age and origin of the deposits of "Madagascar copal" have not yet been resolved. Our objectives are to determine its age and geographical origin, and thus increase its scientific value as a source of biological/palaeobiological information. Although Hymenaea was established in Madagascar during the Miocene, we did not find geological deposits of copal or amber in the island. It is plausible that the evolution of those deposits was negatively conditioned by the type of soil, by the climate, and by the development of soil/litter microorganisms, which inhibit preservation of the resin pieces in the litter and subsoil over 300 years. Our results indicate that "Madagascar copal" is a Recent resin, up to a few hundred years old, that originated from Hymenaea trees growing in the lowland coastal forests, one of the most endangered ecosystems in the world. The included and preserved biota is representative of that ecosystem today and during historical times. Inclusions in this Recent resin do not have the palaeontological significance that has been mistakenly attributed to them, but they do have relevant implications for studies regarding Anthropocene biodiversity loss in this hottest hotspot.

“…Currently the type material of ‘ Tityus’ eogenus is missing [ 12 ]. There are also three buthid species found in the Recent Madagascar copal (less than 250 years old); one species was assigned to the genera Microcharmus (family Microcharmidae) and other two into Palaeogrosphus [ 2 ][ 52 ][ 54 ][ 55 ]. However, these may be considered as extant species, not belonging to the fossil or even subfossil record due to the recent depositional age of copal ( Fig 10 ).…”

New Fossil Scorpion from the Chiapas Amber Lagerstätte

et al. 2015

View full text Add to dashboard Cite

A new species of scorpion is described based on a rare entire adult male preserved in a cloudy amber from Miocene rocks in the Chiapas Highlands, south of Mexico. The amber-bearing beds in Chiapas constitute a Conservation Lagerstätte with outstanding organic preservation inside plant resin. The new species is diagnosed as having putative characters that largely correspond with the genus Tityus Koch, 1836 (Scorpiones, Buthidae). Accordingly, it is now referred to as Tityus apozonalli sp. nov. Its previously unclear phylogenetic relationship among fossil taxa of the family Buthidae from both Dominican and Mexican amber is also examined herein. Preliminarily results indicate a basal condition of T. apozonalli regarding to Tityus geratus Santiago-Blay and Poinar, 1988, Tityus (Brazilotityus) hartkorni Lourenço, 2009, and Tityus azari Lourenço, 2013 from Dominican amber, as was Tityus (Brazilotityus) knodeli Lourenço, 2014 from Mexican amber. Its close relationships with extant Neotropic Tityus-like subclades such as ‘Tityus clathratus’ and the subgenus Tityus (Archaeotityus) are also discussed. This new taxon adds to the knowledge of New World scorpions from the Miocene that are rarely found trapped in amber.

“…Neogrosphus may represent a separate founder allied to Parabuthus (an affinity suggested by the oblique V 1 -V 2 trichobothrial axis on the pedipalp chela shared by the two genera). The genus Palaeogrosphus, known from two subfossils of Pleistocene vintage in Malagasy copal (Lourenço, 1996d(Lourenço, , 2000bLourenço & Henderickx, 2012), also shares a character with Parabuthus (enlarged basal middle lamella on female pectines), but its relationship to the 'Grosphus' group is unclear. More recent local rafting events have been suggested as possible mechanisms to explain the presence of Grosphus mayottensis in the Comoros Archipelago (Lourenço & Goodman, 2009), and the widely separated distributions of Teruelius bistriatus and T. waeberi along the west coast (Lourenço & Wilmé, 2016).…”

Euscorpius

View full text Add to dashboard Cite

Euscorpius is the first research publication completely devoted to scorpions (Arachnida: Scorpiones). Euscorpius takes advantage of the rapidly evolving medium of quick online publication, at the same time maintaining high research standards for the burgeoning field of scorpion science (scorpiology). Euscorpius is an expedient and viable medium for the publication of serious papers in scorpiology, including (but not limited to): systematics, evolution, ecology, biogeography, and general biology of scorpions. Review papers, descriptions of new taxa, faunistic surveys, lists of museum collections, and book reviews are welcome. Derivatio Nominis The name Euscorpius Thorell, 1876 refers to the most common genus of scorpions in the Mediterranean region and southern Europe (family Euscorpiidae).
