As part of a current revision of the Australasian and Pacific orb-weaving spider fauna (family Araneidae Clerck, 1757), a number new combinations are proposed in the genera Acroaspis Karsch, 1878 (3 species), Carepalxis L. Koch, 1872 (1 species), Cyclosa Menge, 1866 (5 species), and Neoscona Simon, 1864 (7 species): Acroaspis lancearia (Keyserling, 1887), comb. n., A. mamillana (Keyserling, 1887), comb. n., A. scutifer (Keyserling, 1886), comb. n., Carepalxis furcifera (Keyserling, 1886), comb. n.; Cyclosa anatipes (Keyserling, 1887), comb. n.; Cyclosa apoblepta (Rainbow, 1916), comb. n.; Cyclosa argentaria (Rainbow, 1916), comb. n.; Cyclosa lichensis (Rainbow, 1916), comb. n.; Cyclosa poweri (Rainbow, 1916), comb. n.; Neoscona decolor (L. Koch, 1871), comb. n.; Neoscona enucleata (Karsch, 1879), comb. n.; Neoscona flavopunctata (L. Koch, 1871), comb. n.; Neoscona floriata (Hogg, 1914), comb. n.; Neoscona granti (Hogg, 1914), comb. n.; Neoscona inusta (L. Koch, 1871), comb. n.; and Neoscona notanda (Rainbow, 1912), comb. n.
The following two Australian species, currently placed in Araneus, are not Araneidae but comb-footed spiders (family Theridiidae Sundevall, 1833): Anelosimus dianiphus (Rainbow, 1916), comb. n. and Theridion xanthostichus (Rainbow, 1916), stat. and comb. n.
The following six species are considered numina dubia as their type material is immature or otherwise unidentifiable (e.g. partly destroyed): Araneus acachmenus Rainbow, 1916; Araneus agastus Rainbow, 1916; Araneus exsertus Rainbow, 1904; Araneus suavis Rainbow, 1899; Carepalxis coronata (Rainbow, 1896); and Heurodes turritus Keyserling, 1886. Heurodes fratellus (Chamberlin, 1924) is considered a nomen dubium and Heurodes porcula (Simon, 1877) is returned to Eriovixia Archer, 1951, Eriovixia porcula (Simon, 1877).
Type material of predominantly Australian species described by E. v. Keyserling (1 species), W. J. Rainbow (10 species), A. T. Urquhart (8 species), and C. A. Walckenaer (2 species) is here considered destroyed or otherwise lost. As it is impossible to identify these species from their original descriptions and considering the known spider fauna from their respective type localities, they are all considered numina dubia: Anepsia crinita Rainbow, 1893; Epeira diabrosis (Walckenaer, 1841); Epeira diversicolor Rainbow, 1893; Epeira ficta Rainbow, 1896; Epeira hamiltoni Rainbow, 1893; Epeira lacrymosa (Walckenaer, 1841); Epeira leai Rainbow, 1894; Epeira mortoni Urquhart, 1891; Epeira notacephala Urquhart, 1891; Epeira obscurta Urquhart, 1893; Epeira phalerata Urquhart, 1893; Epeira pronuba Rainbow, 1894; Epeira rara Keyserling, 1887; Epeira singulara Urquhart, 1891; Epeira sub-flavida Urquhart, 1893; Epeira similaris Rainbow, 1896 (= Araneus urquharti Roewer, 1942 replacement name); Epeira ventriosa Urquhart, 1891; and Epeira viridula Urquhart, 1891.

The genus Araneus Clerck, 1757 (and its junior synonym Epeira Walckenaer, 1805) has been used as a ‘dumping ground’ for many orb-weaving spiders (Araneidae Clerck, 1757) of uncertain affinities world-wide (e.g.
Almost 90 species of Araneus are currently listed for Australia and many more for adjacent biogeographic regions such as South-East Asia and the South Pacific (
The main aim of this study is to transfer species currently listed in Araneus, but also some Carepalxis L. Koch, 1872 and Verrucosa McCook, 1888, to the correct currently recognised genera that occur in Australia and neighbouring regions, such as Acroaspis L. Koch, 1872, Carepalxis, Cyclosa Menge, 1866, and Neoscona Simon, 1864. Two species are transferred to a different family altogether, the comb-footed spiders (Theridiidae Sundevall, 1833). These transfers will allow consideration of these species in future revisionary work in relation to the respective genera, in particular within an Australian context, studies in which they would otherwise likely be overlooked. Similarly, for example, extensive evaluation of Australian type material allowed Araneus mastersi Bradley, 1876 to be considered in a recent study of Australasian Phonognathidae Simon, 1894 (sensu
For a large proportion of Australian Araneidae, including many in the genus Araneus, type material is problematic: either it only includes immature or poorly preserved specimens, or it must be considered lost as it could not be found during intensive investigations of museum collections as part of this study. This includes species described by W. J. Rainbow from Queensland and New South Wales and by A.T. Urquhart from Tasmania, in addition to Australian species described by Graf E. von Keyserling (mainly from the Bradley Collection), and those described by C. A. Walckenaer.
Between ca. 1893 and 1920, William J. Rainbow (1856–1919) published extensively on Australian spiders, but also described spiders from Papuan and Pacific regions (e.g.
Species descriptions in ‘Die Arachniden Australiens nach der Natur beschrieben und abgebildet’ (Koch and Keyserling 1871–1890), published by L. Koch (1825–1908) and Graf E. von Keyserling (1833–1889), were based on several collections, including that of Henry H. B. Bradley (1845–1918), a Sydney-based lawyer and naturalist who himself published on spiders (e.g.
Not all species with lost types are here designated numina dubia. Some of Urquhart’s species could be identified based on the original description; for example, Aerea alticephala Urquhart, 1891 and A. monticola Urquhart, 1893 were recognised as junior synonyms of Arkys simsoni (Simon, 1893) (
In summary, the second aim of this paper is to critically evaluate the species descriptions of species of which type material is uninformative or presumed lost and, in combination with a detailed examination of the respective local fauna, to establish if they can be attributed to a known or undescribed species from collections. If not, they are considered numina dubia here. Some scientists working on mainly the Australian fauna also published papers on spiders from neighbouring regions (e.g.
This study is based on a comprehensive investigation of more than 12,500 records of orb-weaving spiders representing more than 26,000 specimens from collections of all Australian museums and type material lodged overseas, in particular the Natural History Museum, London, the Centrum für Naturkunde (CeNak), Universität Hamburg (Germany), and the Museum für Naturkunde, Zentralinstitut der Humboldt-Universität, Berlin (Germany), where many of the historic types are housed. It forms part of an ongoing revision of the Australian Araneidae that commenced in 2005.
All designations of numina dubia are based on either examination of type material or, in case of lost type material, a critical evaluation of the original description in combination with a consideration of spiders investigated from the respective region where the type material was found.
Some images of type material were taken during visits to the respective institutes with a very simple photographic setup through a tube of a stereomicroscope provided by the institute using an adapter and a Canon Rebel 300D digital camera. The reproductions of these photos here are not necessarily diagnostic at species level but serve to support the taxonomic decisions proposed here.

This study reduces the number of Australian species in Araneus, a genus that presumably does not occur in this country, by 35% from 87 (including 3 subspecies) to 56 (2 subspecies) species. However, it also shows the unsatisfactory taxonomic status within the Australian orb-weaving spiders, as for the remaining 56 Araneus species, new genera need to be established. Similarly, Eriophora Simon, 1864 (three Australian species) and Parawixia F. O. Pickard-Cambridge, 1904 (one Australian species) are unlikely to have true representatives in the Australian fauna as confirmed by multi-loci molecular data (
Three genera of orb-weaving spiders are eliminated from the Australian fauna, one based on a misplaced species (Verrucosa) and two now considered numina dubia (Collina and Heurodes).
The genus Acroaspis was established primarily based on the unique shape of the carapace of the female, specifically the large height of the clypeus and the forward-facing four median eyes that are all placed on a slight forward reaching elevation that forms an extension of the clypeus (
The holotype of the type species of Acroaspis, A. olorina Karsch, 1878 (
The genus has not been treated taxonomically since its description and it is beyond the scope of this study to provide detailed synapomophies of Acroaspis without treating its diverse fauna in Australia, but the examination of male and female genitalia of many Acroaspis males and females in Australian collections representing more than 20 species allows a preliminary characterisation of its genitalic and somatic characters in addition to the characteristic shape of the cephalothorax of the female as described by
The male pedipalp has a single patella spine and a distinct, spoon-shaped paramedian apophysis. The median apophysis is elongated, often with a fleshy protrusion at about half its length, and a curved tip that is armed with two lobes (Fig.
In addition to the type species, two other species are currently listed in Acroaspis: Acroaspis tuberculifera Thorell, 1881 from northern Queensland, placed in the genus when originally described and not examined for the current study, and A. decorosa (Urquhart, 1894) from New Zealand, transferred to the genus by

Cyclosa species generally build small orb-webs with linear web decorations that incorporate undigested prey items. In some species this web decoration has been suggested to function primarily as camouflage to conceal the spider from insects rather than as prey attractant (e.g.

The examination of the immature syntypes of Araneus argentarius clearly shows that these specimens belong to the genus Cyclosa due to the shape of the cephalothorax and abdominal humps.

This species is closely related to Neoscona inusta comb. n. The epigyne scape of the holotype of Araneus notandus is short and spatula-shaped, but some variation, in particular a different course of the fertilisation duct that shines through the scape suggest it to be a different species. A series from Sabai Island (Queensland) in the QM contains five males of this species (in addition to 6 females and 10 immatures) that also confirm it as Neoscona based on the structure of the male pedipalp as reviewed in

The examination of the syntype female of A. dianiphus showed this species to belong to the family Theridiidae. Consultation with specialists working on Australian Theridiidae suggested a placement in Anelosimus based on somatic and genitalic characters (I. Agnarsson, H. Smith personal communication). Therefore, I propose the new generic placement Anelosimus dianiphus (Rainbow, 1916), comb. n. within the spider family Theridiidae pending a generic revision of Australian comb-footed spiders.
Both male and female syntypes of A. dianiphus were recorded in the old, handwritten register of the Australian Museum. The male apparently had disappeared by the time the types were first registered on computer in the 1980s. The original label in the vial of the syntype female mentions only the female, so presumably both syntypes were originally in separate vials. The whereabouts of the male syntype is currently unknown (H. Smith, personal communication).
It is curious to note that

Similar to A. dianiphus, examination of the holotype of Araneus dianiphus xanthostichus showed it to be a theridiid spider. It is more difficult to place this species in a currently recognised genus within the Theridiidae (I. Agnarsson, personal communication). It is clearly not conspecific and likely not congeneric with A. dianiphus comb. n. (see above). Somatic and genitalic characters suggest a placement in or near Theridion (

Rainbow.
Holotype of Araneus suavis Rainbow, 1899: female (abdomen missing), Nendo (Nitendi, Santa Cruz) [ca. 10°25’S, 165°30’E, SOLOMON ISLANDS] (
The abdomen of the female holotype of Araneus suavis is missing and it is doubtful that it will be possible to accurately identify this species by somatic features of the cephalothorax alone. The original description suggests this species may belong to Neoscona, however, the illustration of the epigyne is stylised. Therefore, I consider the species-group name Araneus suavis a nomen dubium.
Epeira coronata Rainbow, 1896b: 629–630, plate. 49, fig. 1.
Carepalxis coronata

Holotype of Epeira coronata Rainbow, 1896: immature female, New England [no exact locality, New South Wales, AUSTRALIA], A.M. Lea (
The holotype of Epeira coronata is immature and of unknown sex and does not allow an accurate species identification. Although the transfer to Carepalxis appears to correctly reflect the somatic characters of this specimen, i.e. the two-humped carapace (Fig.

Heurodes was established based on a juvenile spider from Sydney.
A male and female of H. turritus was illustrated by
Within an Australian context it is likely that Heurodes is a junior synonym of Acroaspis, also characterised by a high clypeus and with many species that show a similar elevated abdomen as H. turritus (see above) (unpublished data). Consequently,
With the unidentifiable type species of Heurodes and a likely junior synonymy of the genus with Acroaspis, it seems most pragmatic to consider the species-group name Heurodes turritus and therefore also the genus-group name Heurodes nomina dubia.
In addition to the type species, H. turritus from Australia, two other species are currently listed in the genus and now require consideration at the genus level: H. fratrellus (Chamberlin, 1924), originally described based on an immature female from China, and H. porculus (Simon, 1877), known currently only from females and initially described from the Philippines and later reported from Singapore (
Heurodes porculus is here returned to Eriovixia, where it was previously placed by
Heurodes fratrellus is here considered a nomen dubium. The type specimen is apparently a juvenile (Chamberlin, 1924, p. 19 “one not fully mature female”) and it was subsequently considered unidentifiable (

The holotype of Anepsia crinita is not present in the Australian Museum and must be considered lost. The original description of this species does not include an illustration of the epigyne nor are female genitalia mentioned anywhere in the text in contrast to all other species described in the same publication.

The holotype female of Epeira hamiltoni is not present in the Australian Museum and must be considered lost. The original stylised description of the epigyne suggests close affinities with Araneus lodicula (Keyserling, 1887), Araneus brisbanae (L. Koch, 1867) or Araneus lutulentus (Keyserling, 1886), none of which are true Araneus (see

Aranea notacephala
(Urquhart).
Syntypes of Epeira notacephala Urquhart, 1891: “several examples” (females), Tasmania [no exact locality, AUSTRALIA] (whereabouts unknown).
The syntypes of Epeira notacephala appear to be lost. The original descriptions suggest close affinities with possibly Araneus arenaceus (Keyserling, 1886). However, there are several undescribed species within this group in south-eastern Australia (unpublished data) and it is not possible to identify Epeira notacephala based on the original description alone. I therefore consider this species-group name a nomen dubium.

Araneus obscuratus

Holotype of Epeira obscurta Urquhart, 1893: female, Tasmania [no exact locality, AUSTRALIA] (whereabouts unknown).
The holotype female of Epeira obscurta seems to be lost. Similar to A. diabrosis, A. singularis (Urquhart, 1891) and A. viridulus (Urquhart, 1891) (see below for the latter two species), this species appears to have affinities to E. pustulosa. Taking the diversity of this group in south-eastern Australian into account, it appears very unlikely that the identity of this species can be elucidated based on the original description alone. I therefore consider the species-group name Epeira obscurta a nomen dubium.

Araneus subflavidus
(Urquhart).
Holotype of Epeira sub-flavida Urquhart, 1893: female, Tasmania [no exact locality, AUSTRALIA] (whereabouts unknown).
The holotype female of Epeira sub-flavida seems to be lost. The original description suggests a large orb-weaving spider, possibly with affinities to Eriophora biapicata or Backobourkia heroine. Taking the diversity of these large spiders in south-eastern Australia into account, it is unlikely that this species can be identified by the original description alone, and therefore I consider the species-group name Epeira sub-flavida a nomen dubium.
