Females with 50 or 51 rings, circa 63 mm long, 5.7 mm wide. <i>Coloration</i> in numerous samples affected by alcohol. Head, collum, antennae, legs, metazonites of body rings and posterior part of telson including anal valves and subanal scale red (Figs 56A, C). Anterior part of body rings and telson dark grey (Figs 56A, C). <i>Eyes</i> with 32–34 ocelli (Fig. 56A). <i>Anterior gonopod</i> sternite basally wide, completely rectangular, apically even slightly wider than basally (Fig. 56D). Mesal process of coxite wide and only slightly protruding (Fig. 56D). Apical process of telopodite large and well-rounded. Retrorse margin wide, projecting above telopodite margin (Fig. 56F) but not protruding basally of apical process (Fig. 56F). <i>Posterior gonopods</i> telopodite bent 90° (Fig. 56G). Lateral margin without a projection (<i>w</i>, Fig. 56E). Apical process (<i>x</i>) wide (Fig. 56E). Membranous lobe (<i>y</i>) large and rectangular (Fig. 56E). In posterior view, an additional small, sclerotized lobe present apically of membranous lobe (Fig. 56G). Projection of sperm canal (<i>z</i>) straight, as long as apical process (Fig. 56G). <b>Distribution and ecology</b> : <i>H. rufus</i> is the <i>Hylekobolus</i> species with the largest area of distribution. It occurs in Southeastern Madagascar from the eastern slopes of the Vohimena range, Midousy Mountains up to Tolongoina (Fig. 54). <b>Etymology:</b> <i>rufus</i>, adjective, refers to the reddish colour pattern (Fig. 56A).
