Remarks. The setal measurements are similar to those provided in the original description, except for Z5, approximately 1.2 times longer in Brazilian specimens. See remarks under Amblyseius leai Tixier & Kreiter concerning the possible synonymy between those species. In addition, little morphological differences may be recognized among A. chiapensis , A. impressus and A. pravus and, therefore, the possibility of these species be synonyms must be further examined in the future.
