Species characters

Adult female habitus

Figure 1


Central (Figs. 2, 3): cuticle with wrinkles or fine folds, longitudinally oriented; cuticle without areolae

Sublateral (Figs. 2,3): posterior region with reticulation forming large cells; anterior region with weak reticulation becoming folds


c1-c1 to d1-d1: cuticle with strong wrinkles and folds; may appear weakly reticulate (Fig. 4)

d1-d1 to e1-e1: cuticle with strong wrinkles and folds, becoming a series of short narrow transverse folds (Fig. 5)

e1-e1 to h1-h1: cuticle with series of short narrow transverse folds; cuticle becoming weakly reticulate towards h1 (Figs. 5, 6)

Sublateral: anterior cuticle reticulate with regular cells becoming longitudinally elonagate towards posterior (Figs. 4, 6)

Dorsal microplates

Separate individual rounded to oblong plates, with multiple series of distinct parallel ridges on dorsal surface aligned in multiple directions (Fig. 7)


palp femur with barbed, broad flat dorsal seta (Fig. 8)


Setae 4a-ventral plate (Fig. 9): cuticle entirely verrucose, with separately formed rounded "warts"; central cuticle often with fused "warts" forming elongate "warts"

Ventral plate (Figs. 10, 11): cuticle weakly verrucose or weakly reticulate with rounded to transversely elongate cells; central cuticle with some fused "warts" forming a few weak transverse bands

Genital plate (Figs. 10, 11): with uniform narrow transverse bands


A long narrow duct, ending in an elongate membranous bulb (Fig. 12)
