Matsumuraja rubi ( Matsumura, 1918)

( Figs 2 , 8b , 10b )

First record in China.

Specimens examined. One apterous viviparous female and one alate viviparous female, CHINA: Hubei (Enshi County), 4.V.2019, No. 45398-1-1, on Rubus , coll. X. L. Zhang; four apterous viviparous females, CHINA: Liaoning (Dandong City), 22.VI.1984, No. Y4909-1-1-2, on Rubus , coll. G. X. Zhang and L. K. Liu (as M. formosana in Zhang et al. 1999b and Jiang et al. 2011).

Diagnosis. Ant. I with one long finger-like process, as long as the segment ( Fig. 2b ); abdominal tergites I–VII each with one paired finger-like spinal tubercles ( Fig. 2e ); abdominal tergites VI–VII with the longest tubercles ( Fig. 2f ); each spinal tubercle with one short, thick, capitate setae distally; abdominal tergites I–V without marginal tubercles or each with one paired, slightly swollen marginal tubercles, and each with one long, thick and capitate setae. Some populations from China have with spinal tubercles shorter than the original description, but the other characteristics are similar.
