The eggs and nymphal stages I-V of Rhagovelia gastrotricha Padilla-Gil, 2011 and Paravelia daza Padilla-Gil & Moreira, 2011, species from southwestern Colombia, are described and illustrated for first time. Immature stages I-III of R. gastrotricha are very similar but differ in the morphometric measures mainly in the width of the head and the width of the pronotum; stages IV and V are characterized by patches of dark color on the ventral abdomen, in the development of the abdomen, of the antennas and the sexual characters of the last abdominal segments. Immature stages of P. daza are distinguished by ocular setae in all instars and by having a dorsal pit on the corner of each eye; the morphometric measures of the width of the head and the width of the pronotum, and the location of the dorsal thoracic plates; stages IV and V by its sexual dimorphism and patches of dark color on the ventral abdomen.
