| abstract | Two new species of the sand-mite genus Leptotrombidium collected in China are described: L. (Monosigmum) zhongi sg. & sp.nov. from Medog in Xizang Autonomous Region (Tibet) and L. (L.) shenzhense sp.nov. from Shenzhen in Guangdong Province. Leptotrombidium (M.) zhongi is characterized by one σ1 or one galeala on leg I (σ1 or g1 = 1) only and has a ʼgenuotibial solenidial frameʼ 1111, a pattern that differs from that seen in the other three subgenera of Leptotrombidium (s.l.), all of which have the frame 2111. L. (L.) shenzhense is characterized by a combination of small body, short and slender legs, sparse body setae and a shallow protruded scutum. |
