Untangling Taxonomy: a DNA Barcode Reference Library for Canadian Spiders
Molecular Ecology Resources (2016) 16, 325–341 doi: 10.1111/1755-0998.12444 Untangling taxonomy: a DNA barcode reference library for Canadian spiders GERGIN A. BLAGOEV, JEREMY R. DEWAARD, SUJEEVAN RATNASINGHAM, STEPHANIE L. DEWAARD, LIUQIONG LU, JAMES ROBERTSON, ANGELA C. TELFER and PAUL D. N. HEBERT Biodiversity Institute of Ontario, University of Guelph, Guelph, ON, Canada Abstract Approximately 1460 species of spiders have been reported from Canada, 3% of the global fauna. This study provides a DNA barcode reference library for 1018 of these species based upon the analysis of more than 30 000 specimens. The sequence results show a clear barcode gap in most cases with a mean intraspecific divergence of 0.78% vs. a min- imum nearest-neighbour (NN) distance averaging 7.85%. The sequences were assigned to 1359 Barcode index num- bers (BINs) with 1344 of these BINs composed of specimens belonging to a single currently recognized species. There was a perfect correspondence between BIN membership and a known species in 795 cases, while another 197 species were assigned to two or more BINs (556 in total). A few other species (26) were involved in BIN merges or in a combination of merges and splits. There was only a weak relationship between the number of specimens analysed for a species and its BIN count. However, three species were clear outliers with their specimens being placed in 11– 22 BINs. Although all BIN splits need further study to clarify the taxonomic status of the entities involved, DNA bar- codes discriminated 98% of the 1018 species. The present survey conservatively revealed 16 species new to science, 52 species new to Canada and major range extensions for 426 species. -
Araneae, Anapidae)
Proc. 16th Europ. ColI. Arachnol. 151-164 Siedlce, 10.03.1997 Egg sac structure and further biological observations in Comaroma simonii1 Bertkau (Araneae, Anapidae) Christian KROPF Natural History Museum Berne, Department oflnvertebrates, Bernastrasse 15, CH-3005 Berne, Switzerland. Key words: Araneae, Anapidae, Comaroma, behaviour, ecology, reproduction. ABSTRACT Specimens of Comaroma simonii Bertkau from Styria (Austria) were kept in the laboratory in order to investigate biological details. Egg sacs were built at the end of June and the beginning of July. They were white-coloured, round in shape with a diameter of 1.47 mm on the average (n = 5) and were attached to vertical surfaces. Each egg sac contained three eggs of pale yellow colour. Normally the egg sac is protected by a silken funnel ending in a tube that points toward the ground underneath. It is assumed that this functions as a means of protection against egg predators and parasites. Spiderlings hatched after 27 days; they most probably moulted twice before leaving the cocoon on the 35th day. They built webs closely resembling those of the adults. Juveniles and sub adults showed no sclerotization of the body and were rarely found in the natural.habitat. There, vertical and horizontal migrations probably occur as a means of avoiding wetness or drying out, respectively. The sex ratio of all collected specimens was 98 females to 54 males. C. simonii is regarded as a 'k-strategist' and an eurychronous species. INTRODUCTION The biology of Anapidae is insufficiently known. For example, data on egg sacs or juveniles are fragmentary (Hickman 1938, 1943; Platnick & Shadab 1978; Coddington 1986; Eberhard 1987). -

The male of Rhoicinus gaujoni Simon and the new species Rhoicinus lugato are described. They co-occur in a whitewater-inundation forest in central Amazonia, Brazil, but were not found in a nearby, inten- sively studied blackwater-inundation forest .

This report enlarges the distribution of the genus from western Sout h America to the central Amazon basin . The spider genus Rhoicinus was proposed by uated on Ilha de Marchantaria (3°15'S, 59°58'W) , Simon (1898a), based on the type species R. gau- the first island in the Solimoes-Amazon river , joni, from Ecuador.

ZooKeys 509: 1–12. doi: 10.3897/ zookeys.509.9711 Abstract Reproduction in arthropods is an interesting area of research where intrasexual and intersexual mecha- nisms have evolved structures with several functions. The mating plugs usually produced by males are good examples of these structures where the main function is to obstruct the female genitalia against new sperm depositions. In spiders several types of mating plugs have been documented, the most common ones include solidified secretions, parts of the bulb or in some extraordinary cases the mutilation of the entire palpal bulb. Here, we describe the first case of modified setae, which are located on the cymbial dorsal base, used directly as a mating plug for the Order Araneae in the species Maeota setastrobilaris sp. -
Psalmopoeus Cambridgei (Trinidad Chevron Tarantula)

Trinidad chevron tarantula, Psalmopoeus cambridgei. [http://www.exoreptiles.com/my/index.php?main_page=product_info&products_id=1127, downloaded 30 April 2015] TRAITS. A large spider, maximum size 11-14cm across the legs, with chevrons (V-shaped marks) on the abdomen (Fig. 1). Males are either grey or brown in colour, and females vary from green to brown with red or orange markings on the legs (Wikipedia, 2013). The Trinidad chevron tarantula is hairy in appearance, has eight legs, and its body is divided into two parts, the cephalothorax and the abdomen which are connected by a pedicel that looks like a narrow stalk (Fig. 2). The cephalothorax has eight legs plus a pair of smaller leg-like appendages (pedipalps) used to catch prey; in males these have palpal bulbs attached to the ends for holding sperm (Fig. 3). The mouth has chelicerae with fangs at the ends and swollen bases that house the venom glands, and there are eight small eyes (Foelix, 2010). However, even with eight eyes the Trinidad chevron tarantula can hardly see and so depends mostly on touch, smell, and taste to find its way. There are organs on their feet to detect changes in the environment and special type of hair on their legs and pedipalps for taste. The second part, the abdomen attached to a narrow waist, can UWI The Online Guide to the Animals of Trinidad and Tobago Ecology expand and contract to accommodate food and eggs; two pairs of spinnerets are located at the end of the abdomen (Fig. -

C. P. 04510. Del. Coyoacán, Ciudad de México, México. E-mail: [email protected] 2Corresponding author Abstract Spider community inventories have relatively well-established standardized collecting protocols. Such protocols set rules for the orderly acquisition of samples to estimate community parameters and to establish comparisons between areas. These methods have been tested worldwide, providing useful data for inventory planning and optimal sampling allocation efforts. The taxonomic counterpart of biodiversity inventories has received considerably less attention. Species lists and their relative abundances are the only link between the community parameters resulting from a biotic inventory and the biology of the species that live there. However, this connection is lost or speculative at best for species only partially identified (e. g., to genus but not to species). This link is particularly important for diverse tropical regions were many taxa are undescribed or little known such as spiders. One approach to this problem has been the development of biodiversity inventory websites that document the morphology of the species with digital images organized as standard views. -
