Genus Trichromadorita Timm, 1961

The genus Trichromadorita was established by Timm (1961) when the type species T. mobilis was described based in a single male. Timm (1961) considered this genus similar to Chromadorita but different based on the presence of a pharynx with three bulbs. According to this author the first bulb is much smaller than the posterior two. Khan (1991) described a second species, T. marinus , based only on females and considered it different from T. mobilis based mainly on the different body length. Khan (1991) also presented an emended diagnosis of the genus mentioning length of> 1mm but this size would exclude T. mobilis with only 0.8 mm. Both Timm (1961) and Khan (1991) illustrate multispiral amphids for their species, without futher comments, which is more characteristic to other families such as Comesomatidae Filipjev, 1918 ; or if in Chromadoridae it is a diagnostic character of subfamily Spilipherinae .

Lorenzen (1994) considered Trichromadorita as a valid genus of Spilipherinae but Tchesunov (2014) omitted it without explanation. We believe that the bulbs of Trichromadorita can be a misinterpretation and it is particularly difficult to distinguish T. marinus from T. mobilis . Considering all information known until now, we consider Trichromadorita as dubious genus until new records and more detailed descriptions are available.
