Compsothrips Reuter, 1901: 214 View in CoL . Type species: Phloeothrips albosignata Reuter View in CoL , by monotypy.

Of the 27 species listed in this genus (ThripsWiki 2023), only seven are known from Asia. Of these seven, four are dealt with below in this paper: reticulates , sinensis , tenebronus and timur . Of the remaining three, C. ramamurthii ( Ananthakrishnan 1964) from India, is distinguished from all other Asian species in having the body and legs predominantly yellow in colour. C. sumatranus Priesner (1928) was based on a single female from Sumatra, and this is discussed further below under C. timur . The last one, C. albosignatus was recorded from Iran ( Hakimara et al. 2019), which seems widespread in the Mediterranean area (ThripsWiki 2023).

All species of Compsothrips are ant mimics with the legs and slender thorax giving the impression of a slender waist, this being emphasized in several species by the contrasting pale colour of the metanotum and first abdominal tergite. The head varies between two extremes amongst species, with some North American species having the head broadly rounded posterior to the compound eyes, but other species, as in the three considered here from China, having the head more elongate and broadest across or just behind the eyes. The body colour is usually dark brown, but one or more of the basal antennal segments may be pale, the metanotum and pelta are often pale, there is a pair of pale spots laterally on the abdomen, and the tenth abdominal segment is bicoloured in one species considered here.

Generic diagnosis. Apterous ant mimics. Head elongate or rounded, usually contracted at base, projecting in front of eyes, or scarcely projecting; eyes strongly prolonged ventrally; interocellar and postocellar setae usually well developed ( Figs 1 View FIGURES 1–8 , 27 View FIGURES 25–30 ); postocular setae usually small and acute, or developed and blunt to expanded; one pair of postocular cheek setae usually developed ( Fig. 27 View FIGURES 25–30 ), sometimes reduced ( Fig. 1 View FIGURES 1–8 ); stylets V-shaped; antennae 8-segmented, sense cones on and IV small, III with 1 or 2, IV with 2; segment VI usually protruding on outer apex ( Figs 6 View FIGURES 1–8 , 15, 16 View FIGURES 9–17 ); pronotal major setae short, blunt or expanded, notopleural sutures complete ( Fig. 1 View FIGURES 1–8 ); basantra present; mesopresternum broad ( Fig. 3 View FIGURES 1–8 ); metathoracic sternopleural sutures usually complete and long ( Fig. 5 View FIGURES 1–8 ); fore tarsal tooth present in both sexes ( Figs 1, 2 View FIGURES 1–8 , 27, 28 View FIGURES 25–30 ); pelta white and broad, rounded triangular ( Fig. 4 View FIGURES 1–8 ); abdominal tergites usually without sigmoid wing-retaining setae; tergite II with white spots anterolaterally, V usually with white spots laterally ( Figs 9–11, 17 View FIGURES 9–17 ); tube surface smooth, without prominent setae ( Figs 7, 8 View FIGURES 1–8 , 14 View FIGURES 9–17 ); anal setae shorter or a little longer than tube.
