TYPE MATERIAL – Female holotype, 89 female paratypes, 3 male paratypes, from <i>Acalypha reptans</i> Sn. (Euphorbiaceae), Piracicaba, São Paulo, Brazil (22 o 42 ’ 30 ” S, 47 o 38 ’08” W), coll. G.J. Moraes, 1 March 2001, on 10 microscopic preparations in the collection of Departamento de Entomologia, Fitopatologia e Zoologia Agrícola, Universidade de São Paulo ­ ESALQ, Piracicaba, São Paulo, Brazil. RELATIONSHIP TO HOST – Small erineal galls on leaves and leaf distortion. ETYMOLOGY – The specific designation <i>korykis</i> is derived from <i>korykis</i>, Greek for gall on leaves, referring to the damage caused by the mite on the host plant.
