Predatory mites from crops and pastures in South Africa: potential natural enemies of redlegged earth mite Halotydeus destructor (Acari: Penthaleidae) Author Halliday, R. B. text Zootaxa 2005 1079 11 64 journal article 50949 10.5281/zenodo.170355 ab581412-8bf4-4718-b555-e389591088a9 1175­5326 170355 9E06506A-35AC-482A-B8D6-B9FD02FB4A5C Gamaselliphis potchefstroomensis (Ryke) Cyrtolaelaps ( Gamaselliphis ) potchefstroomensis Ryke, 1961 : 101 . Gamaselliphis potchefstroomensis : Lee, 1970 : 57 . Specimens examined : Site 94­11 , 7 females , 4 males ; Site 94­13 , 1 male ; Site 94­14 , 19 females , 10 males ; Site 94­31 , 1 male ; Site 94­33 , 1 female , 1 male . Gamaselliphis potchefstroomensis was described from humus at Potchefstroom ( Ryke, 1961 ) and has not been reported since, except when Lee (1970) promoted Gamaselliphis Ryke 1961 from a subgenus to the status of a full genus. Nothing is known of the biology of this species and the next, except that they are presumed to be predatory by analogy with other species of Ologamasidae . The genus includes only five described species, all of which were described by Ryke (1961) . The male is known for only three of these. The collection also includes three specimens of another apparently undescribed species of Gamaselliphis , which has some distinctive features (site 94­31 , 2 males , 1 DN). However, I refrain from attempting a description because the female is unknown.
