This individual was collected at CIMAR24 station 77 at a depth of 212 m at the mouth of the Aysen Fjord, Aysen region. This male specimen matches the diagnosis for the genera. There is clear lateral differentiation of the cuticle from the mid-oesophageal region to the tail. The spicula is short and slightly curved, difficult to distinguish from the gubernaculum. There is a thickening of the cuticular rings for approximately 3 a.b.d., this region ends anteriorly with four papiliform supplements. The tail is elongate conical.
Atochromadora dissoluta
Chromadorella circumflexa
Chromadorella parabolica
Chromadorina germanica (Bütschli, 1874) = C. minor
This individual was collected at Coihuin, Los Lagos region. This species has 17 distinct “cup” shaped precloacal supplements, a distinct oesophageal bulb, and an pigment-spot.
Chromadorina laeta
Chromadorita leptopharynx
Chromadorita menor (Allgen 1927)
This individual was collected at CIMAR24 station Polygon 2B at a depth of 1020 m on the slope of the continental shelf, Los Lagos region. Wieser (1954) only describes a single female collected in intertidal exposed algae. However, the specimen collected at the CIMAR24 station matches the description given by Wieser (1954). The collected specimen is male, there are no visible precloacal supplements, the spicule is short and robust, and the tail is elongate conical.
Dichromadora dissipata
This individual was found at Coihuin, Los Lagos region. It differs from D. dissipata described by Wieser in that it has 9 small precloacal supplements and a single precloacal seta. The amphid appears to be a small rounded loop.

Neochromadora lateralis
Neochromadora torquata
Prochromadorella paramucrodonta (Allgen 1929)
This individual was collected at CIMAR24 station Polygon 2B at a depth of 1020 m on the slope of the continental shelf, Los Lagos region. This specimen is female, the heterogeneous cuticular ornamentation is much stronger in the oesophageal region. The vulva is located mid body. The tail is elongated conical with an unstriated recurved tip.
This individual was collected at CIMAR station 21 at a depth of 163 m in the channel between the islands of Chaulinec and Chulin in the Chiloe inland sea, Los Lagos region. This female specimen fits the diagnosis for the genera, but is distinct from P. paramucrodonta. There are three very obvious solid teeth. The cuticular ornamentation in the cephalic region is homogeneous for about one head diameter, there is then a obvious division of the cuticle and then very strong ornamentation of dots that merge with each other. There is also lateral differentiation which appears to consist of an absence of dots.
