Species characters

Adult female habitus

Figure 1

Prodorsum

Central (Figs. 2, 3): cuticle with strong areolae

Sublateral (Figs. 2, 3): posterior region with some reticulation forming a few large cells; anterior region with large smooth region and narrow band of weak reticulation

Opisthosoma

c1-c1 to d1-d1: cuticle smooth or weakly wrinkled; with a pair of distinct oblique folds adjacent to setae d1 (Figs. 4, 5)

d1-d1 to e1-e1: cuticle smooth or with weak irregular folds, with a few strong transverse folds (Figs. 6, 7)

e1-e1 to h1-h1: cuticle with several transverse folds abruptly becoming longitudinal folds towards h1 (Figs. 8, 9)

Sublateral: cuticle reticulate with large uniform cells, some cells rounded; lateral cells becoming longitudinally elonagate towards posterior (Figs. 7, 8, 9)

Palp

palp femur with barbed, broadly setiform dorsal seta (Fig. 10)

Venter

Setae 4a-ventral plate (Figs. 11, 12): cuticle verrucose laterally with separately formed rounded "warts"; central cuticle with transverse bands formed from fused "warts"

Ventral plate (Figs. 13, 14, 15): cuticle with bands of mixed orientation; lateral and posterior bands tend to be transverse, central bands tend to be oblique

Genital plate (Figs. 13, 14, 15): irregular narrow transverse bands

Spermatheca

A long moderately thick duct, ending in a sclerotised spherical vesicle with a crown of minute proejctions (Fig. 16)

Hosts based on confirmed specimens

Carica papaya (papaya; Caricaceae)
