    Sexual Selection Research on Spiders: Progress and Biases

    Biol. Rev. (2005), 80, pp. 363–385. f Cambridge Philosophical Society 363 doi:10.1017/S1464793104006700 Printed in the United Kingdom Sexual selection research on spiders: progress and biases Bernhard A. Huber* Zoological Research Institute and Museum Alexander Koenig, Adenauerallee 160, 53113 Bonn, Germany (Received 7 June 2004; revised 25 November 2004; accepted 29 November 2004) ABSTRACT The renaissance of interest in sexual selection during the last decades has fuelled an extraordinary increase of scientific papers on the subject in spiders. Research has focused both on the process of sexual selection itself, for example on the signals and various modalities involved, and on the patterns, that is the outcome of mate choice and competition depending on certain parameters. Sexual selection has most clearly been demonstrated in cases involving visual and acoustical signals but most spiders are myopic and mute, relying rather on vibrations, chemical and tactile stimuli. This review argues that research has been biased towards modalities that are relatively easily accessible to the human observer. Circumstantial and comparative evidence indicates that sexual selection working via substrate-borne vibrations and tactile as well as chemical stimuli may be common and widespread in spiders. Pattern-oriented research has focused on several phenomena for which spiders offer excellent model objects, like sexual size dimorphism, nuptial feeding, sexual cannibalism, and sperm competition. The accumulating evidence argues for a highly complex set of explanations for seemingly uniform patterns like size dimorphism and sexual cannibalism. Sexual selection appears involved as well as natural selection and mechanisms that are adaptive in other contexts only. Sperm competition has resulted in a plethora of morpho- logical and behavioural adaptations, and simplistic models like those linking reproductive morphology with behaviour and sperm priority patterns in a straightforward way are being replaced by complex models involving an array of parameters.

    Acta arachnol., 43 (1): 33-36, June 30, 1994 A Taxonomical Study of the Japanese Spider Hitherto Misidentified with Argiope keyserlingi (KARSCH,1878) or A, aetherea (WALCKENAER,1841) Akio TANIKAWAI~ 谷 川 明 男1):ム シバ ミ コガ ネ グ モ の 分 類 学 的 検 討 Abstract The orb-web spider, Argiope aetheroides YIN et al., 1989, is recorded from Japan. The spiders of the species have been wrongly identified with Argiope keyserlingi (KARSCH, 1878) or Argiope aetherea (WALCKENAER,1841) by the previous Japanese authors. When LEvI (1983) revised the spiders of the genera Argiope, Gea and Neogea from the Western Pacific region including Japan, he examined 6 Japanese species : Argiope aemula (WALCKENAER,1841), A. boesenbergi LEVI,1983, A. amoena L. KOCH, 1878, A. bruennichii (SCOPOLI,1772), A. minuta KARSCH,1879, and A. ocula Fox, 1938. Moreover, a doubtful species of the genus is occurring in Japan, which has been identified either with A. keyserlingi (KARSCH,1878) (KISHIDA,1936;YAGINUMA, 1968, 1970, 1977; YAGINUMA& SHINKAI,1971) or with A. aetherea (WALCKENAER, 1841) (SHINKAI& TAKANO,1984, 1987; YAGINUMA,1986; YAGINUMAet al., 1990). In 1990, I collected female and male specimens of the species from Yakushima Island, Kagoshima Pref., Japan, and could confirm the fact that the features of these specimens did not agree with LEVI's (1983) redescriptions and figures of A. keyserlingi and A. aetherea. Then, many specimens of the species were offered by colleagues and collected by myself. After a careful examination of these materials, I came to the conclusion that the species was neither A. keyserlingi nor A.

Molecular insights into the phylo- doi:10.1111/j.1463-6409.2007.00280.x genetic structure of the spider genus Theridion (Araneae, Theridiidae) and the origin of the Hawaiian Theridion-like fauna. — Zoologica Scripta, 36, 337–352. The Hawaiian happy face spider (Theridion grallator Simon, 1900), named for a remarkable abdominal colour pattern resembling a smiling face, has served as a model organism for under- standing the generation of genetic diversity. Theridion grallator is one of 11 endemic Hawaiian species of the genus reported to date. Asserting the origin of island endemics informs on the evolutionary context of diversification, and how diversity has arisen on the islands. Studies on the genus Theridion in Hawaii, as elsewhere, have long been hampered by its large size (> 600 species) and poor definition. Here we report results of phylogenetic analyses based on DNA sequences of five genes conducted on five diverse species of Hawaiian Theridion, along with the most intensive sampling of Theridiinae analysed to date. Results indicate that the Hawai- ian Islands were colonised by two independent Theridiinae lineages, one of which originated in the Americas. Both lineages have undergone local diversification in the archipelago and have convergently evolved similar bizarre morphs. Our findings confirm para- or polyphyletic status of the largest Theridiinae genera: Theridion, Achaearanea and Chrysso.

I am also hugely endebted to Dr Keith Spriggs who became my mentor in the field of RNA and without whom my understanding of the field would have been but a fraction of what it is now. Particular thanks go to Professor John Brookfield, an expert in the field of biological statistics and data retrieval. Likewise with Dr Susan Liddell for her proteomics assistance, a truly remarkable individual on par with Professor Brookfield in being able to simplify even the most complex techniques and analyses. Finally, I would really like to thank Janet Beccaloni for her time and resources at the Natural History Museum, London, permitting me access to the collections therein; ten years on and still a delight. Finally, amongst the greats, Alexander ‘Sasha’ Kondrashov… a true inspiration. I would also like to express my gratitude to those who, although may not have directly contributed, should not be forgotten due to their continued assistance and considerate nature: Dr Chris Wade (five straight hours of help was not uncommon!), Sue Buxton (direct to my bench creepy crawlies), Sheila Keeble (ventures and cleans where others dare not), Alice Young (read/checked my thesis and overcame her arachnophobia!) and all those in the Centre for Biomolecular Sciences.

(Salticidae) began well over acentury ago and until now, NZAC - New Zealand Arthropod Collection, Auckland some 50 species have been described or recorded. However, (Trevor Crosby), the lack oftype specimens, poor original diagnoses, great OMD - Otago Museum, Dunedin (Brian Patrick, Erena intraspecific variation in size and colour and interspecific Barker & Simon Wylie), uniformity in genitalic structure make proper verific3tion of 2MB - Museum fUr Naturkunde der Humboldt species a very difficuh task.

Recent field research and the study of major spider collections (see below) revealed that about 30 genera and Taxonomic review 200 species ofSaltieidae occur in New Zealand (Zabka unpub1.), most of them endemics.
