The former differs from the latter in the higher number of body rings, differences in the anterior and posterior gonopods including a conspicuous longer posterior gonopod in <i>O. rufus</i> than in <i>O. stellaris</i> sp. n. <b>Description.</b> <i>Measurements</i>: males with 46–49 rings, 43–53 mm long, 3.8–4.4 mm wide. Females with 46–48 rings, 56–65 mm long, 5.5–6.3 mm wide. <i>Coloration</i> red (Figs 48 A–D). Rings dorsally with an irregular yellow stripe. Mesozonites and part of metazonites between stripe and opening of ozopores darker blackish (Fig. 48C). <i>Eyes</i> with circa 25 ocelli arranged in five rows (Fig. 48A). <i>Antennae</i> protruding back to ring 5 (Fig. 48A). <i>Male coxal processes</i> only on coxae 3 and 4, short and conical. Prefemur 3–5 with hollow invaginations (Fig. 48B). <i>Preanal process</i> absent (Fig. 48D). <i>Anterior gonopod</i> sternite basally wide, apically elevated into a lobe with a slender, rectangular tip (Fig. 48G). Sternite tip almost as high as telopodite. Coxite not extending beyond sternite, inconspicuous (Fig. 48H). Telopodite on posterior side apically with a small, erect process. Process not projecting above telopodite margins (Fig. 48H). <i>Posterior gonopods</i>: basal stem of telopodite 3.6 times longer than wide (Fig. 48J). Apical part of telopodite star-shaped (Fig. 48I). At mesal margin with three star arms (<i>x</i>, <i>y</i>, <i>z</i> in Fig. 48J). Telopodite apically with a small membranous process (<i>x</i> in Fig. 48I) and a well-developed membranous fringe (<i>w</i>). <b>Intraspecific variation:</b> although specimens were collected from no less than nine localities, spread over rainforest in the whole southeastern region of Madagascar (Fig. 49), no intraspecific variation was observed. The numbers of rings varied within the same population as much as between populations. Females are always larger and thicker than males. <b>Distribution and ecology</b> : this species could be recorded from each single inventoried rainforest south of the Andohahela Isaka-Ivondro corridor (Fig. 49). It was not found (yet?) in the highly endangered (Vincelette et al. 2003) littoral forest of Mandena. <b>Etymology:</b> <i>rufus</i>, adjective, refers to the characteristic red colour pattern.
