Taxonomic revision of fossil Psilodercidae and Ochyroceratidae spiders (Araneae: Synspermiata), with a new species of Priscaleclercera from mid-Cretaceous Burmese amber, northern Myanmar
(Academic Press Ltd - Elsevier Science Ltd, 2021-05)
Psilodercidae contains some 200 known extant species of small spiders that live in tropical rainforests and caves and is mainly restricted to the Oriental biogeographic realm. Interestingly, at least ten different fossil ...
Phylogenomics and genital morphology of cave raptor spiders (Araneae, Trogloraptoridae) reveal an independent origin of a flow-through female genital system
(Wiley Blackwell Publishing, Inc, 2019-11)
The monotypic family Trogloraptoridae was only recently described from caves and old-growth forest of Oregon and California (Western USA). These enigmatic spiders are characterized by striking raptorial claws, and based ...
Insights on vulval morphology in Ochyroceratinae with a rediagnosisof the subfamily and description of the first Argentinean species(Araneae: Synspermiata: Ochyroceratidae)
(Elsevier Gmbh, 2015-12)
We examine the internal morphology of the female genitalia of representatives of the three subfamilies ofthe spider family Ochyroceratidae (Ochyroceratinae, Psilodercinae and Theotiminae) by means of scan-ning electron ...
Molecular phylogeny and revision of the false violin spiders (Araneae: Drymusidae) of Africa
(Wiley Blackwell Publishing, Inc, 2017-12-14)
The family Drymusidae includes 16 cryptic spiders that build irregular websin dark places. The family is distributed in South Africa, the Neotropical,and Andean regions. Here, we use a molecular approach to infer ...
Insights on vulval morphology in Ochyroceratinae with a rediagnosis of the subfamily and description of the first Argentinean species (Araneae: Synspermiata: Ochyroceratidae)
(Elsevier Gmbh, 2016-01)
We examine the internal morphology of the female genitalia of representatives of the three subfamilies of the spider family Ochyroceratidae (Ochyroceratinae, Psilodercinae and Theotiminae) by means of scanning electron ...
Sperm viability in spiders: A first approach using Holocnemus pluchei (Scopoli, 1763) (Synspermiata: Pholcidae)
(American Arachnological Society, 2019-04-27)
Several studies have shown that sperm viability (SV) is a key trait during sexual competition. However, this has not yet been tested in spiders as no protocol has been developed to quantify SV. Here, we describe a methodology ...
The spider Losdolobus nelsoni Pompozzi, 2015 - the first report of the family Orsolobidae in Uruguay (Araneae: Synspermiata)
(Scientific and Technological Research Council of Turkey, 2020)
The family Orsolobidae Cooke, 1965, is newly recorded for Uruguay, with the first record of Losdolobus nelson Pompozzi, 2015, a recently described species that is endemic to the Buenos Aires Province, Argentina, and herein ...
Small pholcids (Araneae: Synspermiata) with big surprises: the lowest diploid number in spiders with monocentric chromosomes
(Amer Arachnological Soc, 2018)
Even though less than 2% of pholcid species have been karyotyped, previous studies documented a wide diversity of diploid numbers and sex chromosome systems. Here, we increase the number of native Brazilian cytogenetically ...
Evolutionary morphology of the male reproductive system, spermatozoa and seminal fluid of spiders (Araneae, Arachnida) e Current knowledge and future directions
(Elsevier, 2014-07)
The male reproductive system and spermatozoa of spiders are known for their high structural diversity. Spider spermatozoa are flagellate and males transfer them to females in a coiled and encapsulated state using their ...
Comparative cytogenetic analysis among filistatid spiders (Araneomorphae: Haplogynae)
(2017-04-01)
The family Filistatidae is considered sister to Synspermiata or sister to Hypochilidae. Cytogenetic knowledge of this family could be useful for understanding the mechanism of chromosome evolution that has occurred within ...
