Trachythrips Hood
Trachythrips Hood, 1930: 317 . Type species Trachythrips watsoni Hood.
Alone amongst the urothripine genera, the members of this genus have the pronotal basantra fully transverse across the anterior margins of the ferna, although the posterior margin of the basantra is not always fully sclerotised in some of the specimens examined. This character state of the basantra, paralleling the geographical distribution of the genus, suggests a single New World radiation with the 11 members of the genus restricted to the American continent and Caribbean islands, between California, Texas, Florida and southern Brazil. Structurally similar to each other, the species of this genus apparently are all wingless, with some differing from others in little more than colour patterns.
