Diagnosis of Chirothrips  -related genera

Species of Chirothrips  and the related genera generally have bodies that are somewhat flattened dorsal-ventrally.

Female: Head small and produced anterior of the compound eyes, with few to many bristle-like, stout or conical setae; compound eyes with 5 pigmented ommatidia ( Fig. 20View FIGURES 18 – 26); antenna 8 -segmented, without microtrichia, segment I enlarged or not, segment II symmetrical to laterally angulated or produced with an apical or subapical sense cone or seta. Pronotum subtrapezoidal, with short, fine or stout setae; prospinasternum well developed, reduced or absent. Mesonotum, metanotum and abdomen with few bristle-like or conical setae, or with numerous, short stout setae. Mesosternal furcal invaginations separated ( Figs 6View FIGURES 1 – 7, 47View FIGURES 43 – 51) or approximated ( Figs 22View FIGURES 18 – 26, 58View FIGURES 52 – 60). Macropterous except for one brachypterous species (which also lacks ocelli). Abdominal posterior segments well developed, with long ovipositor, or rather short, with reduced ovipositor; tergites with posteromarginal flange entire or with lobed or toothed posterior margins.

Male: Apterous or brachypterous, rarely macropterous; head without ocelli; compound eyes with fewer ommatidial facets and often with fewer pigmented facets than females; abdominal sternites with glandular areas. Larva. Antennae and legs reduced.
