Two new species of Phyxelididae are described from southern Africa: Xevioso cepfi sp. nov. (♂♀), mountains in the Niassa Province northern Mozambique, and X. megcummingae urban Harare, Zimbabwe Viphya Mts Malawi. They represent northernmost localities genus. An identification key, partially adapted for species, is presented. The biogeographical importance mountain areas on both sides part Lake Malawi discussed.
Abstract Pisauridae are a global and heterogeneous assemblage of spider genera with diverse morphologies lifestyles. So far, the monophyly inclusion fishing spiders ( Dolomedes ) in this family have not been thoroughly tested. Here, we amend systematics classification these lineages within UCE phylogenomic framework through detailed morphological reappraisal. For estimations their evolutionary age, perform compare outcomes from two divergence estimation approaches, an posteriori likelihood,...
Two Neotropical species of the subfamily Castianeirinae are treated herein. Castianeira spinipalpis Mello-Leito, 1945 was described from a single female specimen; we provide redescription and male is for first time. The newly recorded Paraguay Bolivia. Also, Myrmecotypus rubioi sp. nov. Bolivian Moxos plains, tropical savanna ecoregion Beni department northern new can be distinguished others in genus by having tibia I spination 3-2, coxa II whitish (the remainder dark), unique palpal embolus...
Agriculture is expanding rapidly across the tropics. While cultivation can boost socioeconomic conditions and food security, it also threatens native ecosystems. Oil palm (Elaeis guineensis), which grown pantropically, most productive vegetable oil crop worldwide. The impacts of have been studied extensively in Southeast Asia - to a lesser extent Latin America but, comparison, very little known about its Africa: palm's range, where rapidly. In this paper, we introduce large-scale research...
Abstract Pisauridae Simon, 1890 or “nursery web spiders” are a global and heterogenous assemblage of spider genera with diverse lifestyles, containing builders webless species, as well terrestrial semi-aquatic notably “fishing spiders”, genus Dolomedes Latreille, 1804. Incomplete, unresolved, conflicting phylogenies have so far hampered testing for pisaurid monophyly evolution. Here, we broadly address these questions within phylogenomic comparative framework. Our goals i) reconstruction...
Three new species of Thiratoscirtus are described from Salonga National Park, D.R. Congo: iyomii (), T. kalisia () and khonvoum (). All were caught on the forest floor during a rapid biodiversity inventory represent second report spider collections largest protected tropical rainforest reserve in Africa.
Knowledge on spiders in Paraguay is abysmal, even Salticidae, the most diverse spider family. Prior to this study, 40 species were registered for Paraguay, which may be underestimating true diversity country by five times or more. This study provides a first baseline jumping from evaluation of three salticid collections. We provide 32 new records (a remarkable 76% total number included study) including description PachomiusPeckham & Peckham, 1896, Pachomius rubrogastrussp. nov., and...

A new genus and two species of ant-resembling castianeirine spiders are described from the Neotropics. Grismadox gen. nov. comprises four species: baueri sp. , mazaxoides (Perger & Duperré, 2021) comb. Bolivia, karugua (type species) mboitui (Pett, Paraguay. All diagnosed illustrated. Available ecological data suggests that all primarily epigeal inhabit Grassland savannah type habitats.
A new species of the castianeirine spider genus Copa Simon, 1885, is described from northwestern Mahamavo region in Madagascar. sakalava sp. nov. (♂♀) illustrated and diagnosed against continental Afrotropical congeners.
A new ant-like spider species of the subfamily Castianeirinae, Mazax akephaloi sp. nov., representing second recorded from South America, is described Bolivian orocline and Paraguayan Chaco region. The superficially resembles ramirezi Rubio Daniman, 2014, but can be distinguished this all other congeners by a combination following characters: feathery setae on carapace, tibia I spine formula 54 in males 55 females, embolus sub-apical with spatulate extension, lung-shaped spermathecae II...
Despite being the most diverse family of spiders, Salticidae (jumping spiders) are poorly studied in Madagascar with only 47 total 105 species recorded last 100 years. Here, we describe three new Plexippini Simon, 1901 from dry forests North-western as part an ongoing biomonitoring programme. This paper increases number genus Evarcha 1902 93 to 95 and Thyene 1885 55 56. Additionally, publish specimen records Plexippus petersi (Karsch, 1878) for first time. All diagnosed illustrated through...
Three new species of orb-weaver spider are described from Paraguay. Kaira mbywangiae sp. nov. has a remarkable complexity abdominal humps and hump regions. Two the Humid Chaco flooded wetland region Ñeembucú (Eustala davalosae nov.), one an Atlantic rainforest fragment in eastern Itapuá (Mangora sandovalae nov.).
Abstract There is increasing concern into the decline of insect populations, with corresponding calls for conservation action aimed towards threatened species in particular. However, there a distinct paucity knowledge surrounding habitat requirements, microhabitat selection and actions that may be undertaken vast majority invertebrate species. Carabus intricatus (Coleoptera: Carabidae) Linnaeus, 1761 ancient woodland specialist United Kingdom highly restricted distribution listed as section...
Four new species of Crinopseudoa are described from West Africa. kru sp. nov. (male, female) and C. sinoensis were collected as part a sustainable oil palm project in southern Liberia, nimba expeditions to Mount Nimba Guinea, elisabethae (male) historic museum material Ivory Coast. An updated key is presented we increase the number known 11 15.
A new species of the palpimanid spider genus Scelidocteus Simon, 1907 is described from Salonga National Park, D. R. Congo. The distinguished by structure male and female copulatory organs, both sexes mbembai sp. nov. are illustrated diagnosed against congeners. With this paper, number recorded Salonga, Africa's largest rainforest reserve, rises to a paltry seven, known ten.
Two new species of orb-weaver spiders the genus Larinia Simon, 1874 are described from dry forests Mahajanga region, in north-western Madagascar: mariaranoensis sp. nov. and L. foko Additionally, dasia (Roberts, 1983), previously known only Mahé Island Seychelles, is first recorded for country.
Abstract Microendemic species are of great conservation concern due to their vulnerability stochastic events and environmental change. Therefore, understanding the basic ecology such organisms is integral future efforts conserve them. Here, we present first ecological study only known population Ocyale ghost Jocque & Jocqué 2017 – single within this genus in Madagascar located at a small lake shore north‐west island. We aimed reveal spatial patterns microhabitat selection patch occupancy...
Castianeira monai sp. nov. is described based on specimens from south- western Paraguay and southern Bolivia, the new species has a distribution in Humid Chaco Beni Savanna ecoregion. The distinct embolic morphology with two thicker basal coils four thinner tapering to apex, also proportions of anterior eyes, presence abdominal spines, tibia I ventral spination 3-2 bright red abdomen orange carapace separate this Neotropical congeners.
The castianeirine spider genus Myrmecotypus O. Pickard-Cambridge, 1894 is reported from Paraguay for the first time, with description of a new species, mboitui sp. nov. (♂♀) eembuc Wetlands Complex south-western Paraguay. species belongs to small group elongated and constricted abdomens. Illustrations diagnostic characters are provided. An updated key presented.
