Taxonomic key to adult females of the scale insect species (Hemiptera: Coccomorpha) associated with coffee roots in Colombia

Abstract

A morphology-based illustrated taxonomic key is presented for the identification of the adult females of 59 scale insects that have been recorded associated with coffee roots in Colombia. Previously published doubtful records of species of Diaspididae, Pseudococcidae, and Rhizoecidae were reevaluated and a revised list of scale insects that can be found on coffee roots is presented. A discussion of the morphological variation of Dysmicoccus neobrevipes Beardsley, 1959, Dysmicoccus texensis (Tinsley, 1900) and Dysmicoccus joannesiae (Costa Lima, 1939) is included. The species Distichlicoccus takumasae is emended to Distichlicoccus takumasai.
