Species characters

Adult female habitus

Figures 1, 2, 3

Prodorsum

Central (Fig. 4): cuticle with strong, broad areolae

Sublateral (Fig. 4): posterior region with reticulation forming broad rounded cells; with a distinct cluster of small rounded cells medially; anterior region mostly smooth

Opisthosoma

c1-c1 to d1-d1: cuticle strongly wrinkled (Figs. 5, 6); can appear weakly areolate (Fig. 6)

d1-d1 to e1-e1: cuticle wrinkled with a few strong transverse folds (Figs. 5, 6)

e1-e1 to h1-h1: cuticle with a series of transverse folds, becoming weakly reticulate towards h1-h1 (Figs. 7, 8)

Sublateral: cuticle reticulate with large, uniform, distinctly rounded cells (Figs. 7, 8)

Dorsal microplates

Separate individual, rounded to irregularly rounded plates, with irregular multidirectional ridges on dorsal surface; no series of parallel ridges present (Fig. 9)

Palp

palp femurogenu with barbed, broad flat dorsal seta (Figs. 10, 11)

Venter

Setae 4a-ventral plate (Figs. 12, 13): lateral cuticle verrucose, with separately formed rounded "warts"; central cuticle with raised transverse bands (formed by fused "warts"); transverse bands becoming weaker towards 4a-4a and disappear; central cuticle without separately formed "warts"

Ventral plate (Figs. 14, 15): cuticle weakly verrucose; "warts" are fused to form transverse bands; no separately formed "warts" centrally; often with some separately formed "warts" laterally (Fig. 15)

Genital plate (Figs. 14, 15): uniformly verrucose to verrucose-reticulate, with large cells formed by fused or conglomerate "warts"

Spermatheca

A moderately thick convoluted duct terminates distally in a membranous bulb (Fig. 16)

Hosts based on confirmed specimens

Bixa orellana (Bixaceae); Cinnamomum camphora (Lauraceae); Citrus latifolia, Citrus sp. (Rutaceae); Coffea arabica (Rubiaceae); Datura stramonium (Solanaceae); Phoenix canariensis (Arecaceae)
