“…Such a hypothesis is in conflict with the results of morphological analyses (e.g. Hormiga, 2008;Hormiga and Tu, 2008). A recent interpretation of the male palp sclerites of Stemonyphantes (Gavish-Regev et al, 2013) suggests that in this linyphiid genus the tegular sclerites could be homologues of the conductor and median apophysis, but supported a sister group relationship of Weintrauboa and Pimoa (and thus, Pimoidae monophyly) and of Pimoidae plus Linyphiidae.…”

We test the limits of the spider superfamily Araneoidea and reconstruct its interfamilial relationships using standard molecular markers. The taxon sample (363 terminals) comprises for the first time representatives of all araneoid families, including the first molecular data of the family Synaphridae. We use the resulting phylogenetic framework to study web evolution in araneoids. Araneoidea is monophyletic and sister to Nicodamoidea rank. n. Orbiculariae are not monophyletic and also include the RTA clade, Oecobiidae and Hersiliidae. Deinopoidea is paraphyletic with respect to a lineage that includes the RTA clade, Hersiliidae and Oecobiidae. The cribellate orb‐weaving family Uloboridae is monophyletic and is sister group to a lineage that includes the RTA Clade, Hersiliidae and Oecobiidae. The monophyly of most Araneoidea families is well supported, with a few exceptions. Anapidae includes holarchaeids but the family remains diphyletic even if Holarchaea is considered an anapid. The orb‐web is ancient, having evolved by the early Jurassic; a single origin of the orb with multiple “losses” is implied by our analyses. By the late Jurassic, the orb‐web had already been transformed into different architectures, but the ancestors of the RTA clade probably built orb‐webs. We also find further support for a single origin of the cribellum and multiple independent losses. The following taxonomic and nomenclatural changes are proposed: the cribellate and ecribellate nicodamids are grouped in the superfamily Nicodamoidea rank n. (Megadictynidae rank res. and Nicodamidae stat. n.). Araneoidea includes 17 families with the following changes: Araneidae is re‐circumscribed to include nephilines, Nephilinae rank res., Arkyidae rank n., Physoglenidae rank n., Synotaxidae is limited to the genus Synotaxus, Pararchaeidae is a junior synonym of Malkaridae (syn. n.), Holarchaeidae of Anapidae (syn. n.) and Sinopimoidae of Linyphiidae (syn. n.).

“…The monophyly of the family Linyphiidae is relatively well established on morphological synapomorphies (Hormiga, 1994b; Miller and Hormiga, 2004; Hormiga et al., 2005) as well as its sister group relationship to the relictual family Pimoidae (Wunderlich, 1986; Hormiga, 1993, 1994b, 2003, 2008; Hormiga et al., 2005; Hormiga and Tu, 2008). Within Linyphiidae, the monophyly of the subfamilies Mynogleninae and Erigoninae is also robustly supported, based on the results of several cladistic analyses of morphological data (Hormiga, 1993, 1994b, 2000; Miller and Hormiga, 2004).…”

This study infers the higher-level cladistic relationships of linyphiid spiders from five genes (mitochondrial CO1, 16S; nuclear 28S, 18S, histone H3) and morphological data. In total, the character matrix includes 47 taxa: 35 linyphiids representing the currently used subfamilies of Linyphiidae (Stemonyphantinae, Mynogleninae, Erigoninae, and Linyphiinae (Micronetini plus Linyphiini)) and 12 outgroup species representing nine araneoid families (Pimoidae, Theridiidae, Nesticidae, Synotaxidae, Cyatholipidae, Mysmenidae, Theridiosomatidae, Tetragnathidae, and Araneidae). The morphological characters include those used in recent studies of linyphiid phylogenetics, covering both genitalic and somatic morphology. Different sequence alignments and analytical methods produce different cladistic hypotheses. Lack of congruence among different analyses is, in part, due to the shifting placement of Labulla, Pityohyphantes, Notholepthyphantes, and Pocobletus. Almost all combined analyses agree on the monophyly of linyphioids, Pimoidae, Linyphiidae, Erigoninae, Mynogleninae, as well as Stemonyphantes as a basal lineage within Linyphiidae. Our results suggest independent origins of the desmitracheate tracheal system in micronetines and erigonines, and that erigonines were primitively haplotracheate. Cephalothoracic glandular specializations of erigonines and mynoglenines apparently evolved independently. Subocular sulci of mynoglenines and lateral sulci (e.g. Bathyphantes) evolved independently but glandular pores in the prosoma proliferated once. The contribution of different character partitions and their sensitivity to changes in traditional analytical parameters is explored and quantified.

“…The spider family Pimoidae comprises four genera and thirty one extant species (Platnick, 2008;Hormiga & Tu, 2008). Pimoids are known from Western North America (14 species in two genera, from California through Alaska), Southern Europe (two species in one genus, from Spain, France and Italy) and Asia (15 species in three genera, from the Himalayas area, China, Japan and the Sakhalin islands).…”

“…More recently, Xu and Li (2007) have described another new species from China, W. megacanthus and have reported the occurrence of W. chikunii in the Chinese province of Sichuan. Hormiga and Tu (2008) transferred megacanthus to a new genus, Putaoa, which also includes a second Chinese species, P. huaping Hormiga and Tu, 2008 (the type species). On the other hand, Weintrauboa chikunii had been previously known to occur in Japan and the Sakhalin islands (Hormiga, 2003) and therefore the Chinese records reported by Xu and Li (2007) would represent a significant extension of the distribution range of this species (Sichuan is more than 3,000 km away from the type locality of W. chikunii in Japan; see map in Fig.…”

Weintrauboa yele new species (Pimoidae) is described and illustrated based on specimens collected in China. The taxonomic status and distribution of Weintrauboa insularis (Saito, 1935) new combination and of W. chikunii (Oi, 1979) are discussed and the former species is illustrated based on specimens from the Sakhalin islands. Parsimony analysis of morphological characters provides support for the monophyly of Weintrauboa and for its sister group relationship to the genus Putaoa Hormiga and Tu, 2008. Some comments on the phylogenetic placement of the recently erected family “Sinopimoidae” are provided.
