Stylus with 12–16 microsetae ventrally or laterally (some situated near base of stylus). Measurements (n = 14, except TL where n = 13): TL = 1.84–2.01 (1.93); HL = 0.44–0.50 (0.47); POW = 0.25–0.28 (0.27); HW = 0.26– 0.29 (0.28); PRW = 0.21–0.24 (0.22); PTW = 0.35–0.41 (0.38); AW = 0.34–0.41 (0.37). Female Proximal margin of subgenital plate typically with two setae on each side, but placement asymmetrical and 1–3 setae may be present on each side; lateral setae about twice as long as median setae. Vulval margin with 10–15 slender setae on each side (Fig. 4). Measurements (n = 25, except AW where n = 24): TL = 2.11–2.31 (2.21); HL = 0.49–0.53 (0.51); POW = 0.25–0.29 (0.27); HW = 0.28–0.32 (0.30); PRW = 0.22–0.24 (0.23); PTW = 0.37–0.43 (0.40); AW = 0.40–0.46 (0.43). Remarks Piaget (1880) gives as type locality Madagascar, which is well outside the range of the host species (Madge & McGowan 2002). Clay (1938) examined Piaget’s types, which she found to be identical to material from Borneo. Piaget’s type locality designation is therefore here considered erroneous. We have seen photos of the lectotype and paralectotype (at NHMUK), but not examined these specimens in person. The photo of the female lectotype does not differ from the non-type specimens we have examined.
