Glyptothrips subcalvus ( Hood, 1954)

( Figs 66–73 )

This species has some interesting colour patterns, which are unique within the genus. The first two antennal segments are a very pale yellow, in contrast to the remaining antennal segments and head, which are dark brown in nonmacerated specimens ( Figs 66–68 ). The legs are also highly contrasting, with all tarsi, extreme apex and basal area of tibiae, and apical third or fourth of femora as pale as the basal antennal segments, and the rest of the legs dark brown ( Fig. 66 ); most other Glyptothrips have the legs in some shade of yellow, with at most the junctions between segments slightly paler. Another unusual character state in this species is the presence of only two sense cones on antennal segment IV, which is seen otherwise only in G. flavescens , G. reticulatus and G. interior (all of which with much paler abdomens). The first two also lack a thickened and capitate pterothoracic ventrolateral setae (present in G. subcalvus , Fig. 69 ), and the latter has dilated occipital setae (not dilated in G. subcalvus ).

Known wing forms: micropterous and apterous.

Specimens studied. Holotype ♀; Brazil, Santa Catarina, Nova Teutônia , viii.1952 (F. Plaumann), at NMNH.

Paratype one ♀, same collection data and depositary as holotype .

Five ♂ (non types), same collection data and depositary as holotype (but dated vii.1953, v.1954, v.1955, viii 1955, x.1955).
