These specimens differ in some minor details from the original description. The excretory pore lies more anterior, viz. opposite the posterior part of the isthmus. The phasmids lie also more anterior, 43 % (38 -55) of tail length from the anus. Contrary to Allen's (1955) illustration the cuticle of the terminus is strongly thickened. Tail 2. 1-2.8 anal body widths long, with 34-42 annules. Median bulb located at 46-48 % of neck length from head end. Terminal bulb very long, slightly overlapping. The large dorsal gland nucleus lies close to the base of the bulb. Vulva a transverse slit 11 (JL long. Male not found, female gonads without sperm. Body straight in death.
