Differential diagnosis: G. andohahelensis   differs from G. endemicus   in a slightly different colour pattern and differently shaped telopodites of the anterior ( Fig. 38F View Figure 38 ) and posterior gonopods ( Fig. 38G View Figure 38 ).

Description. Measurements: males with 37 or 38 rings, circa 31–35 mm long (broken), 3.3–3.5 mm wide. Females with 38 rings, 37–43 mm long, 3.7–4.1 mm wide.

Coloration affected by alcohol. Anterior part of head and appendages white to reddish ( Fig. 38A View Figure 38 ). Mesozona and anterior part of metazona dark grey, posterior part of metazona dark orange ( Figs 38 View Figure 38 A–C). Antennae very short, in males protruding back to ring 4 ( Fig. 38A View Figure 38 ), in females to ring 2. Preanal process well-rounded, extending beyond anal valves ( Fig. 38C View Figure 38 ).

Anterior gonopod sternite elongated into a short, well-rounded lobe ( Fig. 38D View Figure 38 ). Coxite large, inconspicuous, with neither processes, nor projections ( Fig. 38D View Figure 38 ). Telopodite visible on anterior side, on posterior side apically with a rounded process ( Fig. 38F View Figure 38 ). Telopodite process starting at mesal margin, laterally curved, slightly extending beyond coxite ( Fig. 38F View Figure 38 ).

Posterior gonopods: telopodite apex not erect, covered by a membranous area ( Fig. 38G View Figure 38 ). A membranous area present between apex and beak, with a short process projecting above margin ( Fig. 38E View Figure 38 ).

Intraspecific variation: the specimens from Manantantely display, in comparison with the holotype from Vasiha, small differences on the beak of the posterior gonopod. These differences are now regarded as intraspecific variation. No variation at all was observed between the holotype collected in Vasiha 1995 and those collected few hundred meters East in Malio 2007 ( Fig. 30 View Figure 30 ). Like in G. endemicus   , females of different size classes are present.

Distribution and ecology: known from the rainforest of Malio, as well as 20 km east from the forest of Manantantely ( Fig. 30 View Figure 30 ). It is currently unclear if similar specimens collected from Ebosika, the Isaka-Ivondro corridor and Ivorona also belong to G. andohahelensis, Single   specimens taken from the littoral forests of Mandena and Sainte Luce show a uniformly black coloration and most likely belong to a yet undescribed species. All specimens of G. andohahelensis   were collected in thin root layers covering large granitic outcrops.

Etymology: andohahelensis   , adjective, after the type locality.
