Differential diagnosis: see key for a separation between P. aureus  and P. vohibasiensis  sp. n. The colour pattern of Pseudocentrobolus aureus  is unique for Malagasy millipedes and allows for an easy identification.

Description. Measurements: males with 40 body rings, 40–48 mm long, 4.4–4.6 mm wide. Females with 39 or 40 body rings, 40–47 mm long, 4.9–5.0 mm wide.

Coloration affected by alcohol. Head, legs, antennae, telson and mesozonites of body rings golden. Metazonites of body rings black ( Figs 31View Figure 31 A–D). Antennae very short, protruding back to body ring 2 ( Fig. 31DView Figure 31). Male coxal processes short and conical, only present on coxae 3 and 4. Coxae 5–7 slightly swollen in appearance ( Fig. 31BView Figure 31). Preanal process well-rounded, prominently extending beyond anal valves ( Fig. 31CView Figure 31).

Anterior gonopod sternite elongated into a wide, mesally slightly notched lobe ( Fig. 34AView Figure 34). Coxite shorter than sternite ( Fig. 34AView Figure 34). Telopodite on anterior side visible, on posterior side apically with a well-rounded process ( Fig. 34BView Figure 34). Telopodite process short and well-rounded, laterally curved, only slightly longer than coxite ( Fig. 34BView Figure 34).

Posterior gonopods: telopodite disc covered with numerous teeth ( Fig. 35BView Figure 35). Membranous process well-developed, basally wide, apically slightly tapering ( Fig. 35AView Figure 35).

Intraspecific variation: although specimens from the type series were collected from three different localities, no intraspecific variation of gonopods, colour or size was observed. Females are always 0.5 mm wider than males.

Distribution and ecology: this species was recorded from spiny forests close to the West Coast ( Fig. 30View Figure 30).

Etymology: aureus  , adjective, refers to the characteristic golden colour pattern of the species ( Fig. 31AView Figure 31).
