description: Key to the <i>Hylekobolus</i> species: 1 Telopodite of posterior gonopod apically with a greatly enlarged membranous area (<i>y</i> in Fig. 66B). Whole posterior gonopod unusually wide........................................................................................... <b> <i>H. anjanaharibe</i> sp. n.</b> – Telopodite of posterior gonopod, membranous area (<i>y</i>) not greatly enlarged. Posterior gonopod very slender (Fig. 55O)................................................. <b>2</b> 2 Apical process of anterior gonopod telopodite tapering towards tip, laterally not projecting (Fig. 34C). Telopodite of posterior gonopod not bending 90° but only 60° (Fig. 64D)............................................ <b> <i>H. andasibensis</i> sp. n.</b> – Apical process of anterior gonopod telopodite laterally always with a wellrounded, wide projection (Fig. 55N). Telopodite of posterior gonopod always bending 90° (Fig. 55O)..................................................................... <b>3</b> 3 Apical process (<i>x</i>) of posterior gonopod enlarged and triangular. Sperm canal discharging on tip (Figs 65B, D)..................................... <b> <i>H. marojejy</i> sp. n.</b> – Apical process (<i>x</i>) of posterior gonopod never triangular (Fig. 55O). Sperm canal on special branch (z) protruding above gonopod............................... <b>4</b> 4 Apical process (<i>x</i>) of posterior gonopod wide and membranous (Figs 57F, 58E). Sternite of anterior gonopod slender, triangular (Figs 57E, 58D)...... <b>5</b> – Apical process (<i>x</i>) of posterior gonopod always completely sclerotized (Fig. 55M). Sternite of anterior gonopod rectangular (Fig. 56D), if triangular then not slender (Fig. 55L)................................................................................ <b>6</b> 5 Central part of collum and anterior half of telson dark grey (Figs 53B, 57A). Retrorse process of anterior gonopod laterally not protruding above telopodite margin (Fig. 57G). Telopodite of posterior gonopod without a membranous lobe (Figs 57F, H).................................................. <b> <i>H. griseus</i> sp. n.</b> – Collum and telson shiny white (Figs 53C, 58A). Retrorse process of anterior gonopods laterally slightly protruding above telopodite margin (Fig. 58F). Telopodite of posterior gonopod with a membranous lobe (<i>y</i> in Figs 58E, G)............................................................................... <b> <i>H. albicollaris</i> sp. n.</b> 6 Lateral margin (<i>w</i>) of posterior gonopod apically with a thick, swollen, wellrounded projection (Figs 55M, 60E). Apical process (<i>x</i>) basally wide, apically extended into a slender projection (Fig. 55M)............................................ <b>7</b> – Lateral margin of posterior gonopod without a swollen projection (Figs 56E, 59E, <i>w</i>). Apical process (<i>x</i>) either wide (Fig. 56E) or slender (Fig. 59E)..... <b>8</b> 7 Collum in anterior half entirely red or white (Figs 53A, 55A). Sternite of anterior gonopods wide, triangular (Fig. 55L). Retrorse process of anterior gonopod laterally not protruding above telopodite (Fig. 55N). Apical process (<i>x</i>) of posterior gonopod basally with a protruding margin (Fig. 55M)................................................................................... <b> <i>H. brachiosauroides</i> sp. n.</b> – Collum grey, only at margins white (Fig. 60A). Sternite of anterior gonopods wide and well-rounded (Fig. 60D). Retrorse process of anterior gonopod laterally widely protruding above telopodite (Fig. 60F). Apical process (<i>x</i>) of posterior gonopod basally wide, but not protruding (Fig. 60E)......................................................................................................... <b> <i>H. montanus</i> sp. n.</b> 8 Apical process (<i>x</i>) of posterior gonopod wide (Figs 56E, 63B). Retrorse process of anterior gonopod slightly protruding above telopodite lateral margin (Fig. 56F)................................................................................................... <b>9</b> – Apical process (<i>x</i>) of posterior gonopod slender (Fig. 59E). Retrorse process of anterior gonopod widely protruding above telopodite lateral margin (Fig. 59F)............................................................................................ <b>10</b> 9 Collum entirely red (Fig. 56A). Sternite of anterior gonopod wide and rectangular (Fig. 56D). Telopodite of posterior gonopod slender, 4 times longer than wide (Fig. 56G). Males 60–65 mm long, 4.8–4.9 mm wide with 49–52 rings...................................................................................... <b> <i>H. rufus</i> sp. n.</b> – Collum anteriorly light, posteriorly darker grey. Sternite of anterior gonopod triangular (Fig. 63A). Telopodite of posterior gonopod very wide, 2 times longer than wide (Fig. 63D). Male 47 mm long, 4.2 mm wide with 46 or 47 rings................................................................................. <b> <i>H. latifrons</i> sp. n.</b> 10 Central part of collum and anterior 3/4 of body rings dark grey (Fig. 59A). Mesal coxite process of anterior gonopod well-developed (Fig. 59D). Retrorse telopodite process relatively slender, but widely projecting (Fig. 59F). Apical process (<i>x</i>) of posterior gonopod almost as slender as projection of sperm canal (Fig. 59E)................................................... <b> <i>H. goodmani</i> sp. n.</b> – Collum and posterior half of body rings light brown (Fig. 62A).
