Okajima, Shûji & Masumoto, Masami, 2025, Some Poaceae-inhabiting Phlaeothripinae (Thysanoptera, Phlaeothripidae) in East Asia, with descriptions of six new genera and 18 new species, Zootaxa 5726 (1), pp. 1-68 : 58

Takeazamiuma gen. nov.

( Figs 61 , 71–74, 81–82 )

From Veerabahuthrips , this genus can be distinguished by the following characteristics: head not protruded in front of compound eyes ( Figs 71 & 72 ) (distinctly protruded in Veerabahuthrips ); cheeks without constriction behind eyes ( Figs 71 & 72 ) (with distinct constriction in Veerabahuthrips ); mesonotum with median cleft incomplete, scarcely reaching middle ( Figs 73 & 74 ) (complete or nearly complete in Veerabahuthrips , cf. Figs 69 & 70 ).

Type-species. Takeazamiuma exilis (Okajima) comb. nov.

Comments. This genus is closely related to Veerabahuthrips , but probably also related to Mychiothrips . The relationship between these genera is discussed in detail under Mychiothrips above. Two species are transferred from Veerabahuthrips to this new genus: Takeazamiuma exilis (Okajima) comb. nov. and Takeazamiuma simplex (Okajima) comb. nov. These two species can easily be distinguished from each other by the key couplet 2 in Okajima (1993b, P. 728). Unfortunately, little is known about these thrips other than that they live on bamboo. There are no new findings to be revised for these two species.

The genus name is derived from two Japanese words, ‘ take ’ and ‘ azamiuma ’ meaning ‘bamboo’ and ‘thrips’ respectively. Gender: feminine.
