Sernatropiella malkini comb. nov. is a proposition of generic placement of Neotropiella malkini, Arlé, 1981 described from Páramo Purace (Coordillera Central, Department Cauca) at 3.000 m altitude in Colombia, 2° 19’01” N, 76° 23’ 53” W, about 52 Km from Popayán city, and more than 600 km from Zipacón, type locality of Sernatropiella pinzonae sp. nov. Arlé described the species with 2 specimens, one of 1.5 and other of 2.1 mm long which were lost. He gave the following important characters: Very dark blue color. Legs less dark. Ant. III and IV yellow. Habitus of Pseudachorutes with paratergites type 3 ( Massoud 1967). Pretergites defined, paratergites very developed. Setae about 100–150 µm. Antennae short and strong. Apical bulb trilobed. Sensilla on dorsal surface of Ant. IV. Ventral surface of Ant. II very short setae among granulations. Ant. III organ with 2 sensilla axe shaped in a slight cuticular fold but uncovered. 5 + 5 eyes, long ocular setae, postantennal organ moruliform smaller than one eye, tubercles elongated in the shape of bananas. Diameter of PAO slightly less than eyes diameter. Buccal cone sharp. Maxillae styliform. Mandible elongated, styliform, with small subapical tooth.

The drawings of Arlé (1981) of mouth pieces are identical to the new genus. Ungues with strong lateral teeth and smooth internal crista, with very small basal tooth. Short furcula, mucro triangular, subequal to dens. Dens with 6 dorsal setae (two proximal very short). Presence of pseudocelli not mentioned in the description. This species is much smaller than type species and the dental setae are of different size, two being smaller than others, and the mucro is subequal to dens. That is why we consider this a valid species in the new genus.
