  Climatic and density-dependent drivers of population dynamics in a hazardous urban scorpion species over seven years Abstract This link goes to a Portuguese section Tityus serrulatus Lutz & Mello (Scorpiones: Buthidae) is the most medically important scorpion in Brazil, responsible for a growing number of accidents in urban areas. Despite its relevance, the population dynamics of this species in anthropogenic habitats remain poorly understood, particularly regarding the influence of abiotic factors on its abundance and reproduction. We analysed long-term data (2006–2013) from T. serrulatus collected in an urban cemetery in the municipality of Americana, São Paulo State, Brazil. Using spatiotemporal mixed models, we evaluated the effects of temperature and humidity at the graves on the abundance of brooded and non-brooded individuals, as well as on the ratio between the two reproductive groups. A total of 21,489 individuals were recorded, including 463 brooded individuals. W...

Further additions to the guardstone spider fauna from China (Araneae: Phrurolithidae)


Abstract

Twenty-three new phrurolithid species belonging to eight genera, including two new genera, are described from China: Beatitas gen. nov. and Punctus gen. nov., Abdosetae baoting sp. nov., Aculithus brevispina sp. nov., Alboculus yanling sp. nov., Beatitas octomaculatus sp. nov., Otacilia allomanubrium sp. nov., O. guposhan sp. nov., O. horizon sp. nov., O. impleta sp. nov., O. maliu sp. nov., O. shaoyao sp. nov., O. shennongjia sp. nov., O. spina sp. nov., O. striata sp. nov., O. subdentigera sp. nov., O. subforcipata sp. nov., O. wenbi sp. nov., O. yongjia sp. nov., Pennalithus liaoning sp. nov., P. micous sp. nov., Punctus maoxian sp. nov., P. taibai sp. nov., Xilithus pugious sp. nov., and X. wangi sp. nov.. The male of Otacilia ailan Liu et al., 2019 and the female of Grandilithus fengshan Liu & Li, 2022 are described for the first time. Two new combinations, Aculithus pseudofabiformis (Liang et al., 2021) comb. nov. and Corealithus nigerus (Yin, 2012) comb. nov., are established. Corealithus subnigerus (Fu, Chen & Zhang, 2016) syn. n. is also synonymized with C. nigerus comb. nov.. Three species, Otacilia dawushan Liu & Li, 2022 syn. n., O. xingguo Liu & Li, 2022 syn. n. and O. zhonglong Liu & Li, 2022 syn. n., are synonymized with O. wugongshanica Liu, 2020.
