FIGURES 1–9. (1–3) Metasternum: (1) Hydatothrips abdominalis , (2) H. proximus , (3) Neohydatothrips trypherus ; (4–5) abdominal tergum V: (4) N. trypherus , (5) H. abdominalis . (6–7) Sericothrips houji : (6) abdominal terga II–IV, (7) head and pronotum. (8–9) H. longjingensis sp. n.: (8) head and pronotum, (9) forewing. (Scale bar=50 microns).

H. jiawensis was described from a single female, and distinguished from the Indian species, H. proximus , by the following characters: wrinkles present on exterior margin of pronotal blotch area outside; abdominal terga without microtrichia on segments II–VII. However, these species are similar especially in the absence of microtrichia on abdominal tergum X and the colour of the body. No differences could be found between the two specimens of jiawensis listed below and the description of proximus . Females of H. chinensis are also similar to H. proximus in morphology, but males of chinensis have a pore plate (=glandular area) only on abdominal sternum V, whereas according to Wang (2007) H. proximus has shorter pore plates only on sterna VI and VII.

Material examined. CHINA: Holotype female of H. jiawensis , Shaanxi Province, Jiawu Mountain, grass, 22.vi.1987, Feng Ji-nian; a paratype female of H. jiawensis , same data except 10.vi.1986, NWAFU.

Distribution. China (Guizho and Shaanxi); India.
