Female macropterous; head and abdomen mostly yellow, thorax and tube brown; legs mostly yellow, femora and tibiae shaded with brown; antennomere I brown with yellow base, II brown, III yellow, IV–VIII brown with yellow base; wings light brown with a dark median line. Antennae 8-segmented, basal antennomeres with stout and capitate setae; III with 3 and IV with 4 sense cones. Head strongly reticulated, about 1.5 times as long as the greatest width; postocular setae much shorter than the length of the eye; lateral margins straight to slightly curved and constricted behind globose eyes; maxillary stylets wide apart. Pronotum reticulated, with 4 pairs of well-developed and capitate setae, anteromarginal pair reduced or absent; prosternal basantra present. Meso- and metanotum strongly reticulated. Pterothorax with a pair of stout and capitate ventrolateral setae on each segment. Pelta trapezoidal and reticulated; abdomen strongly sculptured, tergites II–VII with 2 pairs of wing-retaining setae. Tube cone-shaped, weakly reticulated only at base and without lateral setae, about 2.4x as long as basal width. All legs similar in appearance, tibiae without tubercles, fore tarsi with a tooth. Fore wings without duplicated cilia.
Male macropterous. Similar to female, except for having setae S2 of abdominal tergite IX shorter. Pore plate present on abdominal sternite VIII, covering most of it.
Intraspecific variation
Some specimens bear long and capitate setae on the fore femora.
Genus and similar species information
Glyptothrips is a genus with 14 valid species, with an apparently disjunct distribution between North and South America. The members of this genus have a strongly sculptured body, but tube usually smooth; head incut behind small, globose but well-developed eyes; postocular and main pronotal setae (except anteromarginal pair) well-developed and with capitate apex; and most species bear strong and capitate setae on basal antennomeres and/or ventrolateral region of pterothorax. Glyptothrips longiceps is one of three species in the genus with an elongated head (about 1.5x as long as the greatest width), together with G. divergens and G. saltuarius; it is distinguished from those by the transversely elongate reticulation on the head (equiangular reticulation in the other species), and a relatively shorter tube (less than 0.7x the length of head). A key to the Brazilian Glyptothrips species is available in Lindner et al. (2023).
