“…However more cyphophthalmid species must be analysed to further test this hypothesis, and they could constitute a novel set of characters to resolve important phylogenetic questions such as the possible paraphyly of Sironidae (Giribet et al . ) or the position of autapomorphic species such as Shearogovea mexasca (Shear 1977) (Giribet ).…”

We present the karyotype of the Australian harvestman Austropurcellia arcticosa (Cantrell, 1980) (Arachnida: Opiliones: Cyphophthalmi: Pettalidae), which represents the first cytogenetic analysis of Opiliones from the Australasian ecozone. The diploid complement comprised 30 chromosomes, as reported earlier for two other species of Cyphophthalmi in the family Sironidae, but with a predominance of biarmed chromosomes in A. arcticosa. Morphologically differentiated sex chromosomes were not observed. The course of meiosis is described in the suborder Cyphophthalmi for the first time.

“…Monotypic genera not represented by molecular data are Ankaratra Shear & Gruber, 1996, Iberosiro de Bivort & Giribet, 2004, Manangotria Shear & Gruber, 1996, Marwe Shear, 1985, Odontosiro Juberthie, 1961, Speleosiro Lawrence, 1931, and Stylocellus . Similarly, Shearogovea mexasca , now not considered as a member of Neogoveidae or Neogovea (Benavides & Giribet, 2007; Giribet, 2011), is not represented by molecular data but was included in the combined analysis.…”

“…Shear (1993b) had also proposed the new family Troglosironidae as sister to (Pettalidae + Sironidae) and this result was refuted by Giribet & Boyer (2002), who found it nested within an unresolved Neogoveidae. After some minor familial reassignments – Huitaca Shear, 1979 was removed from Ogoveidae (Giribet & Prieto, 2003) and subsequently included in Neogoveidae (Giribet, 2007b); Fangensis Rambla, 1994 was transferred from Sironidae to Stylocellidae (Schwendinger & Giribet, 2005); Metasiro was transferred from Sironidae to Neogoveidae (Giribet, 2007b); Meghalaya Giribet, Sharma & Bastawade, 2007 was included in Stylocellidae (Clouse et al ., 2009); and Shearogovea mexasca (Shear, 1977) was excluded from Neogoveidae (Benavides & Giribet, 2007; Giribet, 2011) – the families are currently considered to be stable.…”

We investigate the phylogeny, biogeography, time of origin and diversification, ancestral area reconstruction and large‐scale distributional patterns of an ancient group of arachnids, the harvestman suborder Cyphophthalmi. Analysis of molecular and morphological data allow us to propose a new classification system for the group; Pettalidae constitutes the infraorder Scopulophthalmi new clade, sister group to all other families, which are divided into the infraorders Sternophthalmi new clade and Boreophthalmi new clade. Sternophthalmi includes the families Troglosironidae, Ogoveidae, and Neogoveidae; Boreophthalmi includes Stylocellidae and Sironidae, the latter family of questionable monophyly. The internal resolution of each family is discussed and traced back to its geological time origin, as well as to its original landmass, using methods for estimating divergence times and ancestral area reconstruction. The origin of Cyphophthalmi can be traced back to the Carboniferous, whereas the diversification time of most families ranges between the Carboniferous and the Jurassic, with the exception of Troglosironidae, whose current diversity originates in the Cretaceous/Tertiary. Ancestral area reconstruction is ambiguous in most cases. Sternophthalmi is traced back to an ancestral land mass that contained New Caledonia and West Africa in the Permian, whereas the ancestral landmass for Neogoveidae included the south‐eastern USA and West Africa, dating back to the Triassic. For Pettalidae, most results include South Africa, or a combination of South Africa with the Australian plate of New Zealand or Sri Lanka, as the most likely ancestral landmass, back in the Jurassic. Stylocellidae is reconstructed to the Thai‐Malay Penisula during the Jurassic. Combination of the molecular and morphological data results in a hypothesis for all the cyphophthalmid genera, although the limited data available for some taxa represented only in the morphological partition negatively affects the phylogenetic reconstruction by decreasing nodal support in most clades. However, it resolves the position of many monotypic genera not available for molecular analysis, such as Iberosiro, Odontosiro, Speleosiro, Managotria or Marwe, although it does not place Shearogovea or Ankaratra within any existing family. The biogeographical data show a strong correlation between relatedness and formerly adjacent landmasses, and oceanic dispersal does not need to be postulated to explain disjunct distributions, especially when considering the time of divergence. The data also allow testing of the hypotheses of the supposed total submersion of New Zealand and New Caledonia, clearly falsifying submersion of the former, although the data cannot reject the latter. © 2011 The Linnean Society of London, Biological Journal of the Linnean Society, 2012, 105, 92–130.

fueron descritas previo a la publicación de la descripción del género y de la especie tipo, K. mexicana Goodnight y Goodnight, 1947, el uso del nombre genérico se considera como nomen nudum de acuerdo con el Código Internacional de Nomenclatura Zoológica; sin embargo, los nombres específicos son válidos aunque hayan sido publicados en combinación con un nombre genérico válido o no disponible (Código Internacional de Nomenclatura Zoológica, Art. 11) y conservan la autoría y fechas correspondientes. Krusa flava y K. metallica se mantienen como nominales y distintas a las del género Krusa. El género es diagnosticado con base en caracteres morfológicos externos y genitales masculinos y femeninos, y se redescriben las especies mencionadas además de describir a K. hidalguensis sp. nov. Se discute la problemática taxonómica del grupo, la exclusión de K. flava y K. metallica del género, así como la coherencia de nuestros resultados comparados con trabajos moleculares previos. Se presenta una clave dicotómica para la determinación específica. Como consecuencia de este trabajo, se propone la resurrección del género Krusella Roewer, 1953 de Venezuela.
