Supplementary description.

Adult female (n = 12) ( Figs 17–18 ).

Gnathosoma. Measurements of the specimens collected for the cheliceral digits, corniculi, hypostomal and subcapitular setae are within the respective ranges mentioned in the original description.

Dorsal idiosoma. Dorsal shield about 20% shorter and narrower than reported in the original description of the species. Setal measurements were always within the respective ranges mentioned in the original description.

Ventral idiosoma. Measurements of tritosternum, ventral shields and setae compatible with measurements given in the original description, overlapping the corresponding ranges.

Spermatheca. Phytoseiid-type, clearly distinguishable as a sclerotised, elongated cup-shaped structure projecting from the posterior external margin of the base of the coxa IV, ending in a membranous saccular structure.

Legs. Lengths and setation very similar to what were reported in the original description. Leg IV with six macrosetae: three on genu [ad1 63 (60-65), ad2 41 (36-44) and pd1 55 (52-57)]; two on tibia [ad1 41 (34-44) and pd1 54 (52-57)] and on one on basitarsus [pd3 64 (62-65)].

Remarks. This is the first record of this species outside of Brazil. The specimens collected from Ecuador fit well the description provided by Castilho et al. (2012b), based on females from Brazil. Given the very satisfactory original description of this species, new illustrations are not presented in this paper, except for the spermatheca and leg IV macrosetae. The presence of macrosetae on leg IV is not shown in the original description, but an examination of the type specimens showed that they are similar to what is shown herein for the Ecuadorian specimens.
