and the median metanotal setae are a little posterior to the lateral setae. The 

 sculpture of the anterior half of the metanotum consists of parallel lines concentric 

 about the mid-point of the anterior border of the sclerite, and the posterior and 

 lateral areas bear elongate reticulations. The male does not have abdominal 

 drepanae.

 Scirtothrips longipennis (Bagnall) ; Bailey, 1964 : 342-343. 



This is a large species of Scirtothrips with very stout tergal microtrichia. The 

 sternites are devoid of microtrichia medially, the metanotum is reticulate and the 

 median pair of metanotal setae are only a very little posterior to the lateral pair. 

 Pair III of the ocellar setae are on the anterior margins of the ocellar triangle. The 

 species was described from specimens taken on the flowers and leaves of Chamae- 

 dorea under glass at the Brussels Botanic Gardens, Belgium. None of this series 

 remains in the Bagnall collection and the two females labelled by Bagnall ' Type ' 

 were collected in England, Newcastle-on-Tyne, on Adiantum, xii.1908.

This South African genus has recently been revised and a key published for the 

 identification of the eleven species. Limphysothrips was distinguished from Homo- 

 thrips by the presence of a pair of stout spines on the tenth abdominal segment, but 

 the size of these spines is known to vary in at least one member of the genus.
