Hexophthalma Hexophthalma is a genus of spiders in the family Sicariidae.[1] Although the genus was originally erected in 1878 (then with the name Hexomma), it was merged into the genus Sicarius in the 1890s, and remained unused until revived in 2017, when it was discovered that the African species then placed in Sicarius were distinct.Â External links.

Hexophthalma hahni (synonym Sicarius hahni), known along with other members of the genus as the six-eyed sand spider, is a member of the family Sicariidae, found in deserts and other sandy places in southern Africa.Â All species of Hexophthalma produce venom that can have necrotic (dermonecrotic) effects, capable of causing serious or even life-threatening wounds, particularly if the wound becomes infected or the venom spreads in the body. Hexophthalma is a genus of spiders in the family Sicariidae. Although the genus was originally erected in 1878 (then with the name Hexomma), it was merged into the genus Sicarius in the 1890s, and remained unused until revived in 2017, when it was discovered that the African species then placed in Sicarius were distinct. The English name six-eyed sand spiders is used for members of the genus, particularly Hexophthalma hahni. Species in the genus have necrotic (dermonecrotic) venom, and can potentially.

The Phylogenetic Distribution of Sphingomyelinase D Activity in Venoms of Haplogyne Spiders

Wells Department of Biochemistry and Molecular Biophysics, University of Arizona, Tucson, AZ 85721, USA Received 6 October 2002; received in revised form 8 February 2003; accepted 10 February 2003 Abstract The venoms of Loxosceles spiders cause severe dermonecrotic lesions in human tissues. The venom component sphingomyelinase D (SMD) is a contributor to lesion formation and is unknown elsewhere in the animal kingdom. This study reports comparative analyses of SMD activity and venom composition of select Loxosceles species and representatives of closely related Haplogyne genera. The goal was to identify the phylogenetic group of spiders with SMD and infer the timing of evolutionary origin of this toxin. We also preliminarily characterized variation in molecular masses of venom components in the size range of SMD. SMD activity was detected in all (10) Loxosceles species sampled and two species representing their sister taxon, Sicarius, but not in any other venoms or tissues surveyed. Mass spectrometry analyses indicated that all Loxosceles and Sicarius species surveyed had multiple (at least four to six) molecules in the size range corresponding to known SMD proteins (31–35 kDa), whereas other Haplogynes analyzed had no molecules in this mass range in their venom. This suggests SMD originated in the ancestors of the Loxoscelesy Sicarius lineage. These groups of proteins varied in molecular mass across species with North American Loxosceles having 31–32 kDa, African Loxosceles having 32–33.5 kDa and Sicarius having 32–33 kDa molecules.

The three genera share a common characteristic in their venoms: the presence of Sphingomyelinases D (SMase D). SMases D are considered the toxins that cause the main pathological effects of the Loxosceles venom, that is, those responsible for the development of loxoscelism. Some studies have shown that Sicarius spiders have less or undetectable SMase D activity in their venoms, when compared to Hexophthalma. In contrast, our group has shown that Sicarius ornatus, a Brazilian species, has active SMase D and toxic potential to envenomation. However, few species of Sicarius have been characterized for their toxic potential. In order to contribute to a better understanding about the toxicity of Sicarius venoms, the aim of this study was to characterize the toxic properties of male and female venoms from Sicarius tropicus and compare them with that from Loxosceles laeta, one Citation: Lopes, P.H.; Fukushima, of the most toxic Loxosceles venoms.

Eggcase Construction and Further Observations on the Sexual Behavior of the Spider Sicarius (Araneae: Sicariidae)'* by Herbert W
EGGCASE CONSTRUCTION AND FURTHER OBSERVATIONS ON THE SEXUAL BEHAVIOR OF THE SPIDER SICARIUS (ARANEAE: SICARIIDAE)'* BY HERBERT W. LEvi AND LORNA R. LEvi Museum of Comparative Zoology, Harvard University The eggcase of Sicarius is unique among spiders. Its masonry wall resembles in texture the nests of mud dauber wasps.. And, unlike other spider eggcases, it is buried in sand, attached to stones. We do not know of any other masonry construction by spiders, or of other buried eggsacs. Some spiders incorporate sand grains and detritus into their webs or their trapdoors. The European theridiid A chaearanea saxatile (C. L. Koch) makes a thimble-shaped retreat for herself and her silken eggsac (P6tzsch, 963), and covers the thimble with large sand grains and little stones. The colonial European zodariids, Zodarion germanicum (C. L. Koch) and Z. elegans Simon, build retreats under stones. Each semispherical retreat is covered by sand grains from the surroundings, and pieces of bark and spruce needles are woven into the wall. The retreat is used by the .spider and the eggsac is hung up in it. As far as I know, the building of the retreat has not been observed. Wiehle (1953) illustrates a row of large setae in front of the zodariid spinnerets and peculiar branched setae that cover the legs and tarsi. These seta.e are perhaps used for handling the detritus. The unusual 8icarius eggcase was first noted by Simon (I899) 1. Al- though we have two species of Sicarius in culture the possibility of watching eggsac construction seemed at fir.st remote because the only eggcase made in the laboratory appeared to.

Nswatugi Cave – Paintings, Dust and Spiders
Nswatugi Cave – Paintings, Dust and Spiders By Moira FitzPatrick Nswatugi Cave is probably one of the most visited cave in the Matobo Hills because of its fine paintings and easy access. The name, Nswatugi, means the ‘place of jumping’ and, according to local legends, Mlimo (God) leapt from his home at Njelele Hill, landing from his first leap on Nswatugi hill, leaving a ‘footprint’ in the granite. The ‘footprint’ is a natural The floor of this cave is covered in fine clay dust mark, enlarged by artificial pecking.

To increase the number of lead candidates, here we discuss a phylogeny-guided approach for the rational selection of venomous taxa, using tarantulas (family Theraphosidae) as a case study. We found that previous biodiscovery programs have prioritized the three subfamilies Ornithoctoninae, Selenocosmiinae, and Theraphosinae, which provide almost all of the toxin sequences currently available in public databases. The remaining subfamilies are poorly represented, if at all. These overlooked subfamilies include several that form entire clades of the theraphosid life tree, such as the subfamilies Eumenophorinae, Harpactirinae, and Stromatopelminae, indicating that biodiversity space has not been covered effectively for venom biodiscovery in Theraphosidae. Focusing on these underrepresented taxa will increase the likelihood that promising candidates with novel structures and mechanisms of action can be identified in future bioprospecting programs.

Arachnida, Order Araneae. These common arachnids are found in grasslands, forests, orchards, cultivated fields, backyards, gardens, empty lots, parks, and homes. There are some 570 genera and 3,700 species of spiders in North America, north of Mexico. According to an Oklahoma State University checklist at least some 187 genera and 432 species were recorded in the state. Cokendolpher and Bryce (1980) examined arachnid specimens collected at the Wichita Mountains Wildlife Refuge by various groups between 1926 and 1978. Their work yielded a total of 182 arachnid species, of which 170 were spiders. Figure 1.
