Six species, Martella utingae, Sarinda armata, Sarinda marcosi, Simprulla argentina, Simprulla nigricolor, and Zuniga magna, are reported for Bolivia for the first time. The new Bolivian records for M. utingae, S. armata, and S. nigricolor considerably extend the distributional ranges of these species, and the new record for Z. magna shortens a large gap in the known distribution. While the dry diagonal that separates Amazon and Atlantic forests does not appear to act as a dispersal barrier for several Sarindini species, other species appear to be restricted to the areas north or south of the dry diagonal, respectively. Accordingly, high species richness in Bolivian Sarindini may be attributed to the presence of wide spread generalist species and the meeting of several super-regions with their respective faunal elements in Bolivia.","PeriodicalId":38197,"journal":{"name":"Arachnology","volume":"7 1","pages":"20 - 27"},"PeriodicalIF":0.0,"publicationDate":"2022-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85257864","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Because of the difficulty in identifying juveniles, the spider was classified to the genus level only. Dolichothele is represented by 11 small to medium-sized species, with no urticating setae (Valencia-Cuellar et al. 2019; World Spider Catalog 2021). These spiders are typically found under rocks, fallen trunks, and in naturally formed crevices (Valencia-Cuellar et al. 2019).

Even so, investigations which use static allometry as a method for testing specific hypotheses relating to selection remain limited. Sexual dimorphism in the majority of South African scorpion species is poorly investigated, especially in the genus Opistophthalmus, of which the endemic Karoo burrowing scorpion O. karrooensis is nearly completely data deficient. The current study investigates patterns of sexual dimorphism and static allometry in O. karrooensis, based on external morphology. Following character scaling on carapace length, patterns of sexual dimorphism in this species indicate the elongation of male appendages (pedipalp segments, legs, pectines, metasoma, and telson), while females display wider bodies and wide, thick pedipalp segments. These patterns possibly point to an enhanced reproductive output and parental care in females, coupled to a sedentary lifestyle and generalist feeding strategy. Conversely, the male morphology is likely adapted for greater vagility, but should also function during mate-trailing and sexual interactions. In line with these explanations, the body parts in both sexes indicate static allometric patterns pointing (at least in part) to the potential influence of either natural or sexual selection, but further reveal the possibility of intense selection on a number of body parts. Taken together, the selective forces which shape scorpion morphology may be complex, relating to multiple functions of body parts and life-history differences between the sexes.","PeriodicalId":38197,"journal":{"name":"Arachnology","volume":"76 1","pages":"1057 - 1063"},"PeriodicalIF":0.0,"publicationDate":"2021-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82574493","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Spiders build webs that are subjected to wind, thus making habitat selection that much more important for individual spiders. I examined the webs of the grass spider Agelenopsis actuosa (Gertsch & Ivie, 1936), to determine whether they differed in shape, size, and attachment points in short versus tall vegetation in the same general area. I hypothesized that short-grass webs would be larger in diameter, closer to the ground, have more numerous attachments to vegetation, and have specific orientations that accounted for the dominant wind directions. Webs in short grass were significantly shorter in diameter (mean short = 23 ± 6 cm, mean tall = 25 ± 6 cm), lower to the ground (mean short = 7 + 3 cm, mean tall = 17 + 5 cm), and had more numerous attachments (mean short = 24 + 6 attachments, mean tall = 10 + 2 attachments) than webs in tall grass. Short-grass webs were significantly oriented towards north while tall-grass webs showed no significant web orientation. My findings suggest that short-grass webs were smaller because of the wind, and are a predictable circular shape with more attachments. Tall-grass webs were a longer oval in shape, with fewer attachments. Webs are possibly more rigid in short grass with significant orientation perpendicular to the dominant wind direction, possibly for spider thermoregulation.","PeriodicalId":38197,"journal":{"name":"Arachnology","volume":"39 3 1","pages":"993 - 997"},"PeriodicalIF":0.0,"publicationDate":"2021-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78217592","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
