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. 20); 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 6, 47) or approximated (Figs 22, 58). 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.
