Differential diagnosis: H. analavelona  has a unique green/brown colour pattern ( Figs 62A, BView Figure 62). The colour pattern and gonopods clearly identify this species. The gonopods feature a unique combination of characters: the anterior gonopods carry a short

mesal coxite process ( Fig. 62DView Figure 62), the retrorse telopodite process is wide and projecting ( Fig. 62FView Figure 62), the apical process (x) of the posterior gonopods is 4–5 times wider than the sperm canal ( Fig. 62EView Figure 62).

Description. Measurements: male holotype with 45 rings, 56 mm long, 3.6 mm wide. Females with 45 rings, 49–56mm long, 4.65–5.1 mm wide.

Coloration: collum and posterior half of body rings light brown ( Fig. 62AView Figure 62). Body rings in anterior half only laterally with dark green colour, dorsally light brown. Each body ring dorsally with an isolated dark green spot. Legs and antennae light brown ( Fig. 62BView Figure 62). Eyes with 32–34 ocelli ( Fig. 62AView Figure 62).

Anterior gonopod sternite basally wide, apically elevated into a wide, well-rounded rectangular process ( Fig. 62DView Figure 62). Mesal process of coxite wide and only slightly protruding ( Fig. 62DView Figure 62). Apical telopodite process large and well-rounded. Retrorse margin wide, projecting above telopodite margin ( Fig. 62FView Figure 62); margin basally of apical process not projecting ( Fig. 62FView Figure 62).

Posterior gonopods telopodite bent 90° ( Fig. 62GView Figure 62). Projection absent from lateral margin (w, Fig. 62EView Figure 62). Tip of apical process (x) sharp-edged, basally slender, 4–5 times as wide as sperm canal ( Fig. 62EView Figure 62). Membranous lobe (y) large and well-rounded ( Fig. 62EView Figure 62). Projection of sperm canal (z) long and slender, running parallel to apical process ( Fig. 62EView Figure 62).

Distribution and ecology: only known from the Analavelona Mountain ( Fig. 54View Figure 54), an isolated hilltop with rainforest in the otherwise dry southwestern region of Madagascar (DuPuy and Moat 2007).

Etymology: analavelona  , noun in apposition, after the only place where this species can be found, the Analavelona Mountain ( Fig. 54View Figure 54).
