description: Key to the <i>Colossobolus</i> species: 1 Telopodite of posterior gonopod basally with a finger-shaped coxite branch (Figs 9C, 14A, 15F)................................................................................... <b>2</b> – Telopodite of posterior gonopod lacking coxite branch (Figs 16F, 19A, 20G, 21E).......................................................................................................... <b>4</b> 2 Lateral branch of posterior gonopod telopodite curved towards coxite branch, almost forming a circle with latter (Figs 9H, I). Coxite of anterior gonopod in anterior view with a short, wide, well-rounded process (Fig. 9D)................................................................................................... <b> <i>C. semicyclus</i> sp. n.</b> – Lateral branch of posterior gonopod telopodite straight (Fig. 14A). Coxite of anterior gonopod in anterior view with a short pointed process (Fig. 13C)........... <b>3</b> 3 Tarsi whitish (Fig. 13B). Collum completely red (Fig. 13A). Coxite branch of posterior gonopod short, half as long as lateral branch. Lateral branch irregularly curved, becoming apically thicker (Figs 14A, B). Retrorse process absent from mesal margin of telopodite process of anterior gonopod (Fig. 13D)..................................................................................... <b> <i>C. oblongopedus</i> sp. n.</b> – Legs completely red (Fig. 15B). Collum at margins red, median part dark (Fig. 15A). Coxite branch of posterior gonopod long, as long as lateral branch. Lateral branch regularly curved (Fig. 15F). Mesal margin of telopodite process of anterior gonopod protruding into a very short, but pointed retrorse process (Fig. 15D).............................................. <b> <i>C. giganteus</i> sp. n.</b> 4 Telopodites of posterior gonopods oriented face-to-face to one another. Main branch of telopodite overlapping juxtaposed counterpart (Figs 16E, F). Small, 85–100 mm long. Colour of body rings dark brownish (Fig. 16B)................................................................................................ <b> <i>C. minor</i> sp. n.</b> – Telopodites of posterior gonopods oriented parallel to one another. Telopodite main branches not overlapping (Figs 19A, B). Body large,&gt; 120 mm. Colour of body rings always partly red....................................................... <b>5</b> 5 Mesal margin of telopodite process of anterior gonopod widely projecting, almost protruding up to lateral margin (Fig. 18F). Coxite process extraordinary long, but wide and well-rounded, longer than sternite, but far shorter than process of telopodite (Fig. 18E). Telopodite of posterior gonopod not U-shaped. Lateral branch weakly developed, very slender (Fig. 19A). Telopodite main branch separated into two parts, lateral part with large and long membranes, mesal part short and sclerotized. Telopodite lateral branch and both parts of main branch orientated parallel to one another (Figs 19A, B)...................... <b> <i>C. litoralis</i> sp. n.</b> – Mesal margin of telopodite process of anterior gonopod sharp, but not projecting (Fig. 20F). Coxite process present, but short and well-rounded (Fig. 20A). Telopodite of posterior gonopod U-shaped (Fig. 20E). Lateral and main branches apically of similar width. Telopodite main branch not divided into two parts, branch basally sclerotized, apically membranous (Figs 20E, G)........................ <b>6</b> 6 Preanal process apically sharp-edged, slightly shorter than anal valves (Fig. 20C). Main branch of posterior gonopod telopodite of equal width all along (Fig. 20E), longer than lateral branch (Fig. 20G)............ <b> <i>C. aculeatus</i> sp. n.</b> – Preanal process apically rounded, shorter than anal valves (Fig. 21B). Main branch of posterior gonopod telopodite basally very slender, but with a wide, swollen tip (Fig. 21E), shorter than lateral branch (Fig. 21F)................................................................................................... <b> <i>C. pseudoaculeatus</i> sp. n.</b>
