Glyptothrips reticulatus Watson, 1934

( Figs 51–56 )

Originally described from a large series of specimens, Stannard (1955) indicated that Watson’s series represents multiple species. Besides that, two other species have been synonymized with G. reticulatus ( Eurythrips sculpturus Hood and Eurythrips silvarum Hood ; Mound 1976), casting even more confusion over the identity of this name. The original description says it is a “brownish yellow” species, while one of the synonyms ( E. silvarum ) is described as “chestnut brown”. Here we mostly considered the original description for the proposed key and diagnosis, but also considered type specimens of the two synonyms for some observations. This species has only two sense cones on antennal segment IV and lacks a capitate ventrolateral seta, but antennal segments VII and VIII are fully distinct.

Known wing forms: macropterous, micropterous and apterous.

Specimens studied. Paratypes two ♂ and four ♀; United States of America, Florida, from a variety of localities in ferns, pine needles and/or dry leaves, between 1929–1934, at NMNH .

One ♀ (holotype of the synonymized Eurythrips sculpturus ); United States of America, Louisiana, Tallulah , in humus, 11.v.1934 (J.W. Folson), at NMNH .

One ♀ (holotype of the synonymized Eurythrips silvarum ); United States of America, New York, Tompkins County, Enfield Glenn State Park , on fallen pine seedless, 15.ix.1940 (F. R. Nevin), at NMNH .
