Heterothrips Hood

Heterothrips Hood, 1908 . Type-species H. arisaemae Hood.

The species of this genus have nine antennal segments ( Fig.2 ), with one or more rows of sensory pores around the apex of segments III and IV ( Figs 28–30 ). In the head, the tentorial bridge is not developed, and the head and thorax bear only short setae ( Figs 1 , 13 ). The metanotal sculpture consists of concentric lines bearing microtrichia ( Fig 3 ). Moulton (1942) recognised two groups within the genus: group I with free or independent microtrichia on the posterior margins of the abdominal segments, and group II with these microtrichia arising from lobes, plaques or craspeda. These two groups were also recognised in the key to species by Mound & Marullo (1996).
