Abstract:A new species of Tityus, subgenus Atreus (Scorpiones: Buthidae) is described from the Province of Pichincha in the Ecuadorian Andes. Ecuadorian scorpion fauna remains one of the less well studied among those of South America. Nevertheless, some comments are addressed about its remarkable diversity and high level of endemic elements.
“…We have excluded Tityus ( Atreus ) spinatus Pocock from the list of Ecuadorian species since this was synonymized with Tityus ( Atreus ) forcipula Pocock by Lourenço [ 59 ] and was not included by Fet et al [ 41 ] in their catalog of world scorpions. Lourenço and Ythier [ 17 ] indicated, however, that T. ( A. ) spinatus is a species associated with the “ Tityus forcipula ” group but provided no details regarding its validity [ 17 ].…”

“… Tityus ( Atreus ) crassicauda Lourenço & Ythier, 2013:2–9. Type material from Tandayapa (0.01667S, 78.76667 W), Pichincha Province [ 17 ]. T. crassicauda belongs to the “ Tityus forcípula ” morphological group (in the subgenus Atreus ), which comprises medium- to large-sized (above 50 mm), reddish-brown (in adults) species, characterized by the presence of strong spinoid granules at the end of dorsal metasomal carinae [ 59 ].…”

“…Although less known, the work of the Ecuadorian taxonomist Francisco Campos [ 14 , 15 ], together with Behr-Castillo and Correa [ 16 ], also contributed to the knowledge of local scorpions, particularly in the province of Guayas. The work of Wilson R. Lourenço has allowed recognition of Ecuador as part of a region exhibiting the highest alpha-diversity for scorpions in the world, also encompassing Southern Colombia, the Northeast region of Peru, and the Upper Amazon region of Brazil [ 17 ].…”

Ecuador harbors one of the most diverse Neotropical scorpion faunas, hereby updated to 47 species contained within eight genera and five families, which inhabits the “Costa” (n = 17), “Sierra” (n = 34), “Oriente” (n = 16) and “Insular” (n = 2) biogeographical regions, corresponding to the western coastal, Andean, Amazonian, and the Galápagos archipelago regions, respectively. The genus Tityus Koch, in the family Buthidae, responsible for severe/fatal accidents elsewhere in northern South America and the Amazonia, is represented in Ecuador by 16 species, including T. asthenes, which has caused fatalities in Colombia and Panama, and now in the Ecuadorian provinces of Morona Santiago and Sucumbíos. Underestimation of the medical significance of scorpion envenoming in Ecuador arises from the fact that Centruroides margaritatus (Gervais) (family Buthidae) and Teuthraustes atramentarius Simon (family Chactidae), whose venoms show low toxicity towards vertebrates, frequently envenom humans in the highly populated Guayas and Pichincha provinces. This work also updates the local scorpion faunal endemicity (74.5 %) and its geographical distribution, and reviews available medical/biochemical information on each species in the light of the increasing problem of scorpionism in the country. A proposal is hereby put forward to classify the Ecuadorian scorpions based on their potential medical importance.
