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.Due to their flattened stance and laterigrade legs, they are also sometimes known as six-eyed crab spiders.The species name honours Carl Wilhelm Hahn Loxosceles parrami Newlands, 1981 is here renamed to L. parramae (Newlands, 1981), as it was named for a Miss Parram. ............................................................................................................ 13. Flying Sparks Gzsz, 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.

We provide revised distribution information for all of these, and discuss the importance of correct information in the preparation of national faunistic lists. The necrotic effects are caused by a family of proteins related to sphingomyelinase D, present in the venom of all sicariid spiders. Female inner spermathecae consist of a broad chamber, extending anteriorly in, numerous tubes, each ending in one or more spherical vesicles (Fig. While hunting, it uses its front legs to catch the prey. on the signs and symptoms of envenomation. The six-eyed sand spider has a shy temperament but its potential venomous bites make it one of the deadliest spiders. (NMZB A/11518); 1 ♀, 1 imm., Sentinel Ranch, Hunters Camp, 2229Ab. 19); this is. In the present paper the Afrotropical species of the genus, thorough examination of all the available specimens from nine major collections, the species. In evaluating all of the localities provided in the treatments of species in these two papers, as well as subsequent taxonomic literature, we found that 25 of the 68 nominative species treated by Purcell and 38 of the 92 species treated by Simon had incorrect distribution data in the World Spider Catalog (2019).

Spider venoms are cocktails of toxic proteins and peptides, whose composition varies at many levels.  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.  In 1893, Eugène Simon transferred Hexophthalma hahni to the genus Sicarius, and Hexophthalma fell out of use, until a phylogenetic study in 2017 showed that the African species of Sicarius, including Sicarius hahni, were distinct, and revived the genus Hexophthalma for them.

We estimated a time-calibrated, total-evidence phylogeny of Sicariinae, and used published distribution records to estimate climatic niche and biome occupancy. Due to their flattened stance and laterigrade legs, they are also sometimes known as six-eyed crab spiders. The genus was ﬁ rstly described as Hexomma (Karsch 1878) for the species H. hahni, but this name was preoccupied and replaced with Hexophthalma (Karsch 1879).
