Un nouveau symphyle (Myriapoda) de Colombie et considérations sur les appendices régénérés

H. colombiana n.sp. exhibits, like H. ivorensis Juberthie-Jupeau et Kehe, 1978, one pair of macrochetae on tergitae II, III, IV, VI, VII and IX. It differs from H. ivorensis by the characters of antennae, legs and spinnerets, but like this one, the male exhibits secondary sexual characters. These two species have wide hairs truncated at the top on segments 5 and 6 in H. ivorensis, segments 4, 5 and 6 in H. colombiana. The origin of these species from a common stock is discussed. The very high number of regenerated appendages leads to suppose the presence of an active predator.
