Material examined: 2 ♂, Holotype: 1 ♂ (47.5 mm long), CAS BLF 9244 (CASENT 9032795), Madagascar, Province Antsiranana, Parc National de Marojejy , 25.7 km 32° NNE Andapa, 10.3 km 314° NW Manantenina, montane rainforest, 1575 m, 14°26’42” S, 049°44’30” E, leg. B. L. Fisher, 21.XI.2003 Paratypes: 1 ♂ (im m.), CAS BLF 9244, sa me data as holotype .

Differential diagnosis: the posterior gonopods of H. marojejy sp. n. with the large triangular expansion of the tip (x), which even carries the sperm canal ( Fig. 35D ), separates this species from any other Hylekobolus species.

Description. Measurements: males with 48 rings, circa 47.5 mm long, 4.4 mm wide.

Coloration: faded in alcohol. Anterior part of collum, posterior parts of rings, antennae, legs, anal process, valves and entire scale reddish, remaining parts dark grey. Eyes with circa 32 ocelli.

Anterior gonopod sternite basally wide, apically weakly tapering, tip well-rounded ( Fig. 63A ). Mesal coxite process slender and protruding ( Fig. 35D ). Apical process of telopodite elongated and slender. Retrorse margin wide, projecting above telopodite ( Fig. 35C ); margin basally of process not projecting.

Posterior gonopods telopodite bent 90° ( Fig. 35D ). Telopodite 2 times longer than wide ( Fig. 35B ). Projection absent from lateral margin (w, Fig. 35B ). Apical process (x) wide ( Fig. 35B ). Membranous lobe (y) small and well-rounded. An additional sclerotized, rectangular lobe visible in anterior view ( Fig. 35B ). Projection of sperm canal (z) long and slender, slightly curved towards apical process ( Fig. 35D ).

Distribution and ecology: H. marojejy sp. n. is currently only known from Marojejy ( Fig. 54 ).

Etymology: marojejy , noun in apposition, refers to the type locality, the rainforest of Marojejy.
