Ricinulei are among the most obscure and cryptic arachnid orders, constituting a micro-diverse group with extreme endemism. The 76 extant species described to date are grouped in three genera: Ricinoides, from tropical Western and Central Africa, and the two Neotropical genera Cryptocellus and Pseudocellus. Until now, a single molecular phylogeny of Ricinulei has been published, recovering the African Ricinoides as the sister group of the American Pseudocellus and providing evidence for the…

Historical biogeography of a neglected family of armoured harvestmen (Opiliones : Laniatores : Icaleptidae) with the first record and a new genus for tropical Mesoamerica
The results revealed that E. pilosus is a derived lineage within the family Icaleptidae, thus it is transferred from Zalmoxidae, and the new name Trypophobicica gen. nov. is proposed to accommodate it, with the new combination Trypophobica pilosa comb.
The first troglobitic species of Gymnobisiidae (Pseudoscorpiones : Neobisioidea), from Table Mountain (Western Cape Province, South Africa) and its phylogenetic position
This species is the first troglobitic species of the family and one of the most highly modified pseudoscorpions from the Afrotropical Region.
Phylogeny, evolution and systematic revision of the mite harvestman family Neogoveidae (Opiliones Cyphophthalmi)
A comprehensive molecular phylogeny of the family Neogoveidae including representatives of all genera but the monotypic Tucanogovea Karaman, 2013, and new information on the type species described by Jochen Martens in 1969 are provided, supported by Phylogenetic analyses based on maximum likelihood, parsimony and Bayesian inference.
Four New Species of “Hooded Tick-Spiders” (Ricinulei, Ricinoididae) from South and Central America, with Clarification of the Identity of Cryptocellus leleupi Cooreman, 1976
The present contribution describes four new species of the mostly South American genus Cryptocellus, long considered a nomen dubium, of the Ricinulei Thorell, 1876, or “hooded tick-spiders,” among the least studied arachnid orders.
A remarkable new species of the magnus species-group of Cryptocellus (Arachnida, Ricinulei) from Ecuador, with observations on the taxonomy of the New World genera.
A new ricinuleid species, Cryptocellus chimaera sp. nov., is described based on a male specimen from Northwest Ecuador (Esmeraldas, Reserva Ecológica Mache-Chindul, Estación Biológica Bilsa). This
COI mtDNA barcoding and morphology for the description of a new species of ricinuleid of the genus Pseudocellus (Arachnida: Ricinulei: Ricinoididae) from El Triunfo Biosphere Reserve, Chiapas, Mexico
A new species of epigean ricinuleid of the genus Pseudocellus Platnick, 1980 from El Triunfo Biosphere Reserve, Chiapas, Mexico is described. DNA barcoding utilizing mitochondrial cytochrome c
The Opiliones tree of life: shedding light on harvestmen relationships through transcriptomics
The integration of state-of-the-art molecular techniques and analyses, together with the broadest taxonomic sampling to date presented in a phylogenomic study of harvestmen, provide new insights into harvestmen interrelationships, as well as a general overview of the general biogeographic patterns of this ancient arthropod group.
Advancing mite phylogenomics: Designing ultraconserved elements for Acari phylogeny
This work designs targeted ultraconserved genomic elements (UCEs) probes, intended for resolving the complex relationships between mite lineages and closely related arachnids, and builds a phylogeny using 13 existing Acari genomes as well as 6 additional taxa from a variety of genomic sources.
A transcriptome-based phylogenetic study of hard ticks (Ixodidae)
This work provides a baseline for studying the evolutionary history of ticks and finds an unexpected acceleration of substitutions for mitochondrial sequences of Prostriata, and for nuclear and mitochondrial genes of two species of Rhipicephalus, which it relates with patterns of genome architecture and changes of life-cycle, respectively.


Phylogenomic interrogation of arachnida reveals systemic conflicts in phylogenetic signal.
It is shown that phylogenetic signal for the monophyly of Arachnida is restricted to the 500 slowest-evolving genes in the data set, and that outgroup selection without regard for branch length distribution exacerbates long-branch attraction artifacts and does not mitigate gene-tree discordance, regardless of high gene representation for outgroups that are model organisms.
Forest refugia in Western and Central Africa as ‘museums’ of Mesozoic biodiversity
The phylogenetic and molecular dating results suggest that Ricinulei diversified in association with the fragmentation of Gondwana, and suggest that refugia may have acted as ‘museums’ conserving ancient diversity rather than as engines generating diversity during successive episodes of climatic fluctuation in Africa.
Revision of the fossil ricinuleids
  • P. Seiden
  • Biology
    Transactions of the Royal Society of Edinburgh: Earth Sciences
  • 1992
The fossil ricinuleids are described, and their systematic relationships revised, based on a study of all British and American specimens, and a probable basal dichotomy between the fossil and extant forms is indicated.
Evaluating topological conflict in centipede phylogeny using transcriptomic data sets.
The Amalpighiata hypothesis, which shows little gene-tree incongruence and is robust to the influence of among-taxon compositional heterogeneity, implies convergent evolution in several morphological and behavioral characters traditionally used in centipede phylogenetics, but accords with patterns of first appearances in the fossil record.
Arthropod relationships revealed by phylogenomic analysis of nuclear protein-coding sequences
This work presents strongly supported results from likelihood, Bayesian and parsimony analyses of over 41 kilobases of aligned DNA sequence from 62 single-copy nuclear protein-coding genes from 75 arthropod species, providing a statistically well-supported phylogenetic framework for the largest animal phylum.
A phylogenetic analysis of the arachnid orders based on morphological characters
Results suggest that attempts to resolve specific nodes based on individual characters, lists of similarities, evolutionary scenarios, etc., are problematic, as they ignore broader impacts on homoplasy and analytical effects on non-target nodes.
Two new species of ricinuleids of the genus Pseudocellus (Arachnida: Ricinulei: Ricinoididae) from southern Mexico.
The number of known species of the genus Pseudocellus increases to 25, and Mexican species to 16, indicating that Mexico has the highest diversity of ricinuleids in the world.
A new species of Cryptocellus (Arachnida, Ricinulei) from the Kofán Territory in southwestern Colombia
The new species is described from a male specimen obtained from leaf litter in the Kofan Territory, southwestern Colombia and exhibits a series of interesting morphological features including the presence of cuticular pits and a unique shape of the male copulatory apparatus.
The Phylogeny of the Extant Chelicerate Orders
The phylogeny of the extant chelicerate orders is examined in the light of morphological and molecular evidence, with the placement of solifugids and the status of the pedipalps responsible for most disagreement fairly robust to variation in analysis parameters.
