<P> The Solifugae apparently have neither venom glands nor any venom - delivery apparatus such as the fangs of spiders, stings of wasps, or venomous setae of caterpillars (e.g., Lonomia or Acharia species). One 1978 study is frequently quoted, in which the authors report detection of an exception to this rule in India, in that Rhagodes nigrocinctus had venom glands, and that injection of the secretion into mice was frequently fatal . However, no supporting studies have confirmed either the facts of the matter, such as by independent detection of the glands as claimed, or the relevance of the observations if correct . Even the authors of the original account denied having found any means of delivery of the putative venom by the animal, and the only means of administering the material to the mice was by parenteral injection . Given that many non-venoms such as saliva, blood and glandular secretions can be lethal if injected, and that no venomous function was even speculated upon in this study, there is no evidence as yet for even one venomous species of solifugid . </P> <P> Because of their unfamiliar spider - like appearance and rapid movements, Solifugae have startled or even frightened many people . This fear was sufficient to drive a family from their home when one was discovered in a soldier's house in Colchester, England, and caused the family to blame the solifugid for the death of their pet dog . An Arizona resident developed painful lesions due to a claimed solifugid bite, but could not produce a specimen for confirmation . Though they are not venomous, the powerful chelicerae of a large specimen may inflict a painful nip, but nothing medically significant . </P>
