Hylekobolus anjanaharibe Wesener

sp. n.

Hylekobolus anjanaharibe Wesener  , sp. n.


Material examined: 1 ♂, 1 ♀ Holotype: 1 ♂ (52 mm long), BLF CAS 8152, Madagascar, Province Toamasina, Montagne d’Anjanaharibe , 19.5 km 27° NNE Ambinanitelo, montane rainforest, 1100 m, 15°10’42” S, 049°38’06” E, leg. Fisher, Griswold et al., 12–16.III.2003GoogleMaps  Paratype: 1 ♀, BLF CAS 8152, same data as holotypeGoogleMaps  .

Differential diagnosis: the posterior gonopods of H. anjanaharibe  sp. n. are very wide, unique for Hylekobolus  . The apical membranous area (y) is greatly enlarged, forming two large lobes ( Fig. 66BView Figure 66).

Description. Measurements: male with 50 rings, circa 52 mm long, 3.8 mm wide. Female (with eggs) with 50 rings, 54 mm long, 4.2 mm wide.

Coloration: faded in alcohol. Central part of collum, anterior parts of rings, head and anal valves dark green, appendages, posterior margin of rings and preanal process light brown. Eyes with 32–34 ocelli.

Anterior gonopod sternite wide, with a well-rounded tip ( Fig. 66AView Figure 66). Mesal coxite process slender and elongated ( Fig. 66AView Figure 66). Apical process of telopodite large and wellrounded. Retrorse margin wide, slightly projecting above telopodite ( Fig. 66CView Figure 66); margin basally of process not projecting ( Fig. 66CView Figure 66).

Posterior gonopods telopodite always straight ( Fig. 66DView Figure 66). telopodite of posterior gonopod only 1.5 times longer than wide ( Fig. 66BView Figure 66). Projection absent from lateral margin (w, Fig. 66BView Figure 66), but area and tip completely covered by a whitish membranous area. Apical process (x) absent ( Fig. 66BView Figure 66). Membranous lobe (y) bilobed, very large, covering whole tip ( Fig. 66BView Figure 66). Projection of sperm canal (z) long and slender ( Fig. 66DView Figure 66).

Distribution and ecology: H. anjanaharibe  sp. n. is currently only known from Anjanaharibe, a mountain in north Madagascar ( Fig. 54View Figure 54).

Etymology: anjanaharibe  , noun in apposition, refers to the type locality, Anjanaharibe.
