Related and similar species

Bhatti (2000) recognised 10 species-groups in the genus Trichromothrips, and placed T. obscuriceps in the group in which species have sternal discal setae. Unfortunately this species remains known only from the original specimens, about 35 females and one larva, mounted onto three slides. All of these specimens are poorly preserved, and most are uncleared. Two of the slides are labelled “Brisbane Hacker”, but the third slide is labelled “Host Crinum Lily, Brisbane 16-9-31 H.Hacker”.
