Fisher , Griswold et al., 12–16.III.2003 Paratype : 1 ♀ , BLF CAS 8152, same data as holotype . 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. 66B ). 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. Figure 66. Hylekobolus anjanaharibe sp. n. , male holotype. A anterior gonopod, anterior view B right posterior gonopod, anterior view C anterior gonopod, posterior view D right posterior gonopod, posterior view. Apo = apodeme; Cx = coxite; St = sternite; T = telopodite. Not to same scale. Anterior gonopod sternite wide, with a well-rounded tip ( Fig. 66A ). Mesal coxite process slender and elongated ( Fig. 66A ). Apical process of telopodite large and wellrounded. Retrorse margin wide, slightly projecting above telopodite ( Fig. 66C ); margin basally of process not projecting ( Fig. 66C ). Posterior gonopods telopodite always straight ( Fig. 66D ). telopodite of posterior gonopod only 1.5 times longer than wide ( Fig. 66B ). Projection absent from lateral margin ( w , Fig. 66B ), but area and tip completely covered by a whitish membranous area. Apical process ( x ) absent ( Fig. 66B ). Membranous lobe ( y ) bilobed, very large, covering whole tip ( Fig. 66B ). Projection of sperm canal ( z ) long and slender ( Fig. 66D ). Distribution and ecology : H. anjanaharibe sp. n. is currently only known from Anjanaharibe, a mountain in north Madagascar ( Fig. 54 ). Etymology : anjanaharibe , noun in apposition, refers to the type locality, Anjanaharibe.
