Related species

The genus Trichromothrips, together with its synonym Dorcadothrips, currently includes 38 species (Masumoto & Okajima, 2005; Li et al., 2019). These species apparently originated in the area between Southeast Asia and Australia, but several of them are now more widespread around the world (Bhatti, 2000). T. xanthius is reported to be unique within this genus in having coarse-grained dark areas on either side of abdominal sternites V & VI (Nakahara, 1993).

Biological data

Presumably originally from Southeast Asia, but taken in greenhouses widely around the world (Nakahara, 1993: 408).
