Glyptothrips arkansanus Hood, 1957a

( Figs 5–8 )

This species is most similar to G. flavescens , the type species of Glyptothrips . However, G. arkansanus can be differentiated by having a suture between antennal segments VII–VIII (whereas in G. flavescens both antennal segments are fully fused), the abdominal pale lines much more apparent ( Figs 6–7 ) than in G. flavescens , and the antennae mostly yellow ( Fig. 5 ), while it is mostly brown from antennal segment III onwards in G. flavescens . Glyptothrips arkansanus also lacks the “tubercles” on pronotal and metanotal sculpture, which is characteristic of G. flavescens .

Known wing forms: macropterous and micropterous.

Specimens studied. Lectotype ♀; United States of America, Arkansas, Fayetteville , on Andropogon virginicus L., 16.iii.1957 (W.H. Whitcomb), at NMNH.

Paralectotypes one ♂ and one ♀, same collection data and depositary as lectotype .
