New record and occurrence map of Tityus serrulatus Lutz & Mello, 1922 (Scorpiones, Buthidae) in the state of Rio Grande do Sul, southern Brazil

Abstract: Abstract:The Brazilian scorpion Tityus serrulatus is recorded for the first time in the central region of Rio Grande do Sul, thus filling a gap of 567 km in its distribution. A specimen of the scorpion was collected in the urban area of the municipality of Santa Maria (29°43′51.31″ S, 053°48′5.74″ W) on 31 June 2014. A map was generated with the points of occurrence of the species in the state.

“…Tityus serrulatus is considered the most dangerous of the four and, it is distributed throughout the country. This species is typical of the dry forest environments of the Cerrado and Caatinga but can be found in many different types of natural and urban environments [45]. Historically, T. serrulatus occupied only a small portion of the Cerrado biome in Minas Gerais State, but the current wider distribution is most likely related to human colonisation stretching from the Atlantic Coast to extreme western regions [46].…”

“…serrulatus , popularly known as “yellow scorpion.” Adult specimens typically measure 5 to 7 cm in length. As suggested by its common name, its coloration consists of pale yellow legs and pedipalps , with a darker shade of yellowish brown on the body and tip of the tail [ 70 ]. They display a serration along the dorsal face of the distal segments 3 and 4 of the tail, as small teeth, which confer the name “ serrulatus ” to the species [ 71 ] ( Fig 5 ).…”

“…The spreading of T. serrulatus could have been supported by the road network, the main transportation system used in Brazil. In fact, some reports describe the introduction of this species in nonendemic states relating them to agricultural products transported from other states [70,72,74,80,81].…”

“…While phylogenetic comparative methods are a relatively recent approach to understanding venom variation [ 26 ], studies measuring venom potencies have a rich history, with numerous standardized measures of potencies, such as LD 50 , available across species spanning the scorpion phylogeny. Here, we use this rich history to collate LD 50 potency values [ 20 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 , 38 , 39 , 40 , 41 , 42 , 43 , 44 ] and morphology measures [ 14 , 19 , 35 , 45 , 46 , 47 , 48 , 49 , 50 , 51 , 52 , 53 , 54 , 55 , 56 , 57 , 58 , 59 , 60 , 61 , 62 , 63 , 64 , 65 , 66 , 67 , 68 , 69 , 70 , 71 , 72 , 73 , 74 ,…”
