( Figs 60–65 )

Liothrips pallipes Karny, 1913: 110 .

Gynaikothrips kuwanai Moulton, 1928b: 308 ; Mound, 2020: 389.

Liothrips reynvaanae Priesner, 1968: 203 ; Mound, 2020: 389.

Female macroptera. Body length 2.8–3.1 mm. Color brown, antennal segments I and II dark brown, same colour as head, III–VI yellow, VII and VIII greyish brown; all femora brown, tibiae and tarsi yellow; fore wings pale brown with a darker stripe; major body setae hyaline.

Head 1.4 times as long as wide ( Fig. 60 ); po setae situated near middle of dorsum, almost pointed and longer than eyes; maxillary stylets retracted into posterior third of head, widely separated; antennal segments III and IV same length, 1.6 times length of segment II ( Fig. 65 ). Pronotum with 5 pairs of strong setae ( Fig. 61 ), blunt or weakly expanded, aa setae shorter than or equal to am setae; mesopresternum boat-shaped, with irregular median protrusion ( Fig. 62 ); metanotal sculpture dense and longitudinal. Pelta triangular ( Fig. 63 ); tergite II laterally with 4–5 accessary setae ( Fig. 64 ); tube shorter than head.

Specimens examined. Taiwan, Taihoku (Taipei), paratype female from Smilax , 31.x.1926 (Moulton 2214) ; Shulin (Taipei), 4 females, 2 males from Smilax sp., 17.xi.1930 (coll. Takahashi); Kendin (Pingtung), 3 females from Albizia julibrissin , 13.i.1993 .

Comments. The yellow colour of all the tibiae contrasting with the brown colour of all the femora make this species easy to recognise.
