Among them about 100 species are dangerous for human. Members of Latrodectus and Loxosceles share the habitats of human beings. Chemically, spider venom is heterogeneous, and contains poly peptide, poly amine, nucleic acid, free amino acid, monoamine, neurotoxin, enzyme and inorganic elements. In enzymes, proteases, hyaluronidase, sphingo-myelinase, phospholipase and isomerase form necrosis. Venom is neurotoxic, and it causes paralysis. In Turkey, some species of Latrodectus, Steatoda, Loxosceles, Cheiracanthium, Segestria, Agelena, Tegenaria, Araneus and Argiope are venomous. The specimens that collected from different habitats and localities of Turkey were examined under stereo microscope. They were identified as species level, and the venom organs of some spiders were investigated morphologically with the light and electron microscope. Key words: Spider, Venom, Turkey, Araneae. INTRODUCTION The aim of this article is to explain the venomous spiders, and inform their habitats and distributions in Turkey. About 50.000 species have been described on the world. All of the spiders have venom glands except the members of MATERIAL AND METHODS Uloboridae and Archaeidae. Preys of spiders are insects, other arthropods and invertebrates, and from vertebrates small fishes, The specimens were collected from different habitats frogs, lizards, birds and even mammalians such as mice.

  • The First Record of Family Segestriidae Simon, 1893 (Araneae: Dysderoidea) from Iran
    Serket (2014) vol. 14(1): 15-18. The first record of family Segestriidae Simon, 1893 (Araneae: Dysderoidea) from Iran Alireza Zamani Department of Animal Biology, School of Biology and Center of Excellence in Phylogeny of Living Organisms in Iran, College of Science, University of Tehran, Tehran, Iran [email protected] Abstract The family Segestriidae Simon, 1893 and the species Segestria senoculata (Linnaeus, 1758) are recorded in Iran for the first time, based on a single female specimen. Keywords: Spiders, Segestriidae, Segestria senoculata, new record, Iran. Introduction Segestriidae Simon, 1893 is a small family of medium-sized, araneomorph, ecribellate, haplogyne spiders with three tarsal claws which are globally represented by 119 species in three genera (Platnick, 2014). These spiders are six-eyed, and are usually distinguishable by having their third pair of legs directed forwards. From taxonomic point of view, Segestriidae is closely related to Dysderidae, and are considered as a member of the superfamily Dysderoidea. The type genus, Segestria Latreille, 1804, is consisted of 18 species and one subspecies which are mostly distributed in the Palaearctic ecozone (Platnick, 2014). One of the more distributed species is Segestria senoculata (Linnaeus, 1758). This species, like most segestriids, occupies a wide variety of habitats; they prefer living in holes within walls and barks, or under stones, where they build a tubular retreat, with strong threads of silk radiating from the entrance (Roberts, 1995). So far, about 500 spider species of more than 38 families have been reported from Iran (based on our upcoming work on the renewed checklist and the history of studies), but no documentation of the family Segestriidae has been reported from Iran (Mozaffarian & Marusik, 2001; Ghavami, 2006; Kashefi et al., 2013).

  • Spider Bites
    Infectious Disease Epidemiology Section Office of Public Health, Louisiana Dept of Health & Hospitals 800-256-2748 (24 hr number) www.infectiousdisease.dhh.louisiana.gov SPIDER BITES Revised 6/13/2007 Epidemiology There are over 3,000 species of spiders native to the United States. Due to fragility or inadequate length of fangs, only a limited number of species are capable of inflicting noticeable wounds on human beings, although several small species of spiders are able to bite humans, but with little or no demonstrable effect. The final determination of etiology of 80% of suspected spider bites in the U.S. is, in fact, an alternate diagnosis. Therefore the perceived risk of spider bites far exceeds actual risk. Tick bites, chemical burns, lesions from poison ivy or oak, cutaneous anthrax, diabetic ulcer, erythema migrans from Lyme disease, erythema from Rocky Mountain Spotted Fever, sporotrichosis, Staphylococcus infections, Stephens Johnson syndrome, syphilitic chancre, thromboembolic effects of Leishmaniasis, toxic epidermal necrolyis, shingles, early chicken pox lesions, bites from other arthropods and idiopathic dermal necrosis have all been misdiagnosed as spider bites. Almost all bites from spiders are inflicted by the spider in self defense, when a human inadvertently upsets or invades the spider’s space. Of spiders in the United States capable of biting, only a few are considered dangerous to human beings. Bites from the following species of spiders can result in serious sequelae: Louisiana Office of Public Health – Infectious Disease Epidemiology Section Page 1 of 14 The Brown Recluse: Loxosceles reclusa Photo Courtesy of the Texas Department of State Health Services The most common species associated with medically important spider bites: • Physical characteristics o Length: Approximately 1 inch o Appearance: A violin shaped mark can be visualized on the dorsum (top).

  • Development of the Cursorial Spider, Cheiracanthium Inclusum (Araneae: Miturgidae), on Eggs of Helicoverpa Zea (Lepidoptera: Noctuidae)1
    Development of the Cursorial Spider, Cheiracanthium inclusum (Araneae: Miturgidae), on Eggs of Helicoverpa zea (Lepidoptera: Noctuidae)1 R. S. Pfannenstiel2 Beneficial Insects Research Unit, USDA-ARS, Weslaco, Texas 78596 USA J. Entomol. Sci. 43(4): 418422 (October 2008) Abstract Development of the cursorial spider, Cheiracanthium inclusum (Hentz) (Araneae: Miturgidae), from emergence to maturity on a diet of eggs of the lepidopteran pest Helicoverpa zea (Boddie) (Lepidoptera: Noctuidae) was characterized. Cheiracanthium inclusum developed to adulthood with no mortality while feeding on a diet solely of H. zea eggs and water. The number of instars to adulthood varied from 4-5 for males and from 4-6 for females, although most males (84.6%) and females (66.7%) required 5 instars. Males and females took a similar time to become adults (54.2 ± 4.0 and 53.9 ± 2.0 days, respectively). Egg consumption was similar between males and females for the first 4 instars, but differed for the 51 instar and for the total number of eggs consumed to reach adulthood (651.0 ± 40.3 and 866.5 ± 51.4 eggs for males and females, respectively). Individual consumption rates suggest the potential for high impact of C. inclusum individuals on pest populations. Development was faster and survival greater than in previous studies of C. inc/usum development. Key Words spider development, egg predation Spiders have been observed feeding on lepidopteran eggs in several crops (re- viewed by Nyffeler et al. 1990), but only recently has the frequency of these obser- vations (Pfannenstiel and Yeargan 2002, Pfartnenstiel 2005, 2008) suggested that lepidopteran eggs may be a common prey item for some families of cursorial spiders.

SUMMARY A case of arachnidism produced in a woman by Segestria florentina has been reported from Leverano, a town near Lecce, Salento, South Italy. At a local level, the bite provoked a keen and persistent pain and oedema of the part affected, followed by paresy of the left hand lasting some hours. The consequent symptomatology, both local and systemic, disappeared in about a week. INTRODUCTION In nature all spiders are hunters and use many different and sophisticated strategies, the most effective of them being the production and injection of poison through their chelicerae, used to immobilize and kill their prey. Man is only occasionally bitten, with a derived fear and confusion also among those who must to treat the situation. In Italy a large majority of autochthonous spiders are inoffensive, and usually only a small number of them bite man causing, through its poison, a series of local, rarely systemic, symptoms.

MoRo (Neurophysiology Laboratory, Depart- ment of Zoology, Bangalore University, Bangalore-560056, India) : The disposition and external morphology of trichobothria in two arachnids. Acta arachnol,, 36: 11-23 (1988). The distribution and external morphology of trichobothria in the whip scorpion, Thelyphonus indicus, and the scorpion, Heterometrus fulvipes, have been studied. While the whip scorpion has its trichobothria remarkably reduced in number to just 10 distributed on the tibiae of the legs, the scorpion has totally 96 trichobothria with 48 on each pedipalp. The sockets as well as hair shafts of the trichobothria on the antenniform legs of the whip scorpion differ widely in their appearance from those on the walking legs. The trichobothria of the scorpion resemble those on the antenniform legs of the whip scorpion, but differ due to the lamellated wall of the cup of the trichobothrium in the scorpion. The directions of mobilities of individual trichobothria in both the arachnids have also been mapped. Introduction The trichobothria of arachnids are very fine hair sensilla remarkably sensi- tive to air currents, articulated within and emerging from independent sockets in the cuticle. They were first discovered on the extremities in Araneae by DAHL (1883) who called them `Horhaare' (hairs of hearing). The sensitivity of trichobothria to air currents was demonstrated in a scorpion,. (HOFFMAN, 1967) and a spider (GORNER & ANDREWS, 1969). Since the number and arrangement of trichobothria remain constant within individuals of a species but vary from species to species, trichobothrial patterns are used in systematics and classification and in the study of development (WEY- 12 GEETHABALIand Sulochana D.

J ÄGER Forschungsinstitut Senckenberg, Senckenberganlage 25, D60325 Frankfurt am Main, Germany. email: [email protected] ABSTRACT. The palpal claw is evaluated as a taxonomic character for 42 species of the spider family Sparassidae and investigated in 48 other spider families for comparative purposes. A pectinate claw appears to be synapomorphic for all Araneae. Elongated teeth and the egg-sac carrying behaviour of the Heteropodinae seem to represent a synapomorphy for this subfamily, thus results of former systematic analyses are supported. One of the Heteropodinae genera, Sinopoda, displays variable character states. According to ontogenetic patterns, shorter palpal claw teeth and the absence of egg-sac carrying behaviour may be secondarily reduced within this genus. Based on the idea of evolutionary efficiency, a functional correlation between the morphological character (elongated palpal claw teeth) and egg-sac carrying behaviour is hypothesized. The palpal claw with its sub-characters is considered to be of high analytical systematic significance, but may also give important hints for taxonomy and phylogenetics. Results from a zoogeographical approach suggest that the sister-groups of Heteropodinae lineages are to be found in Madagascar and east Africa and that Heteropodinae, as defined in the present sense, represents a polyphyletic group.
