Phrasterothrips affinis Bagnall 



(Text-fig. 60) 



Phrasterothrips affinis Bagnall, 1924k : 633-634. 



The present author has not examined fuscus Moulton, but the other species 

 included in Phrasterothrips may be recognized as follows : 



1 Sculpture of metanotum consisting of a series of short parallel lines close together, 



not forming any reticulation medially ; epimera with one major seta . omercooperi 



— Sculpture of metanotum reticulate medially, at least near extreme anterior border . 2 



2 Median reticles of metanotum almost as broad as they are long ; epimera with two 



major setae ; anterior marginal setae of pronotum variable in length . conducans 



— Median reticles of metanotum narrow, broad only near anterior border ; eipmera 



with one major seta ; anterior marginal seta of pronotum no longer than discal 

 setae .............. affinis 



Further material is essential to the understanding of these species, since the 

 anteromarginals are variable in conducans and the epimerals are variable in an 

 undescribed species according to Stannard (1957). P. affinis is based on one male 

 and one female.

Phrasterothrips conducans Priesner, 1921b : 210-213. 

 Phrasterothrips braziliensis Bagnall, 1924k : 632. Syn. n. 



This is the type-species of the genus, and the above synonymy is based on a com- 

 parison of the types of braziliensis with material determined as conducans by 

 Priesner, collected in Brazil from galls on Myrica sp.

Phrasterothrips omercooperi Bagnall 

 (Text-fig. 63) 

 Phrasterothrips omer-cooperi Bagnall, 1924k : 633. 



The metanotal sculpture is rather similar to that of affinis, but in omercooperi the 

 pronotal anteromarginals are well developed.

Plectrothrips collar is Bagnall 

 Plectrothrips collaris Bagnall, 1909J : 531-533. 



According to Stannard (1957) Plectrothrips is well represented in the islands of the 

 Western Pacific. Kladothrips has a rather similar pronotum, but in Plectrothrips 

 the pelta is broad basally and the wing retaining setae only weakly developed.
