Li & Jacobus, is described based on egg, nymph, and winged stages from Dali Bai Autonomous Prefecture, Yunnan Province, China. The nymph of the new species is closely related to (Allen, 1971), whose nymphs share a similar tuberculation of head, pronotum, and mesonotum. However, the nymph of our new species can be distinguished based on the structures of male sternum IX and abdominal tergal tubercles. In addition, the new species is distributed in subtropical high-altitude areas. The description of the male imago of the new species is the first certain one for the genus . Data associated with our new species allow for expanded discussion and diagnosis of and closely related genera. An identification key for nymphs of these groups is provided.

Background: Brazilian spotted fever is a tick-borne disease caused by the bacterium Rickettsia rickettsii, whose main vector in Brazil is the tick Amblyomma sculptum. Amplifying hosts are essential for the perpetuation of this bacterium in the tick population as they can be sources of infection during bacteremic periods. Recent studies demonstrated the ability of suids (Sus scrofa) to sustain populations of A.

Troponin C (TnC) is a calcium-binding subunit of the troponin complex that regulates muscle contraction in animals. However, the physiological roles of TnC, especially in insect development and reproduction, remain largely unknown. We identified seven TnC genes encoding four EF-hand motif protein in the rice pest, the brown planthopper Nilaparvata lugens.
