The nomenclature used for the dorsal idiosomal chaetotaxy follows that of Lindquist and Evans (1965), the leg chaetotaxy follows that of Evans (1963), and the names of the pores on the dorsal shield follow Johnston and Moraza (1991). Measurements of structures are expressed as minimum-maximum ranges in micrometres (μm).The leg length was measured from the base of coxa to the apex of tarsus, including the pretarsus.

The draft drawings were scanned and then embellished under the software Adobe Photoshop CS6. The morphological drawings of the new species were done by the help of the drawing instrument (Leica DM 3000 LED microscope) equipped with a drawing tube. The specimens of the new species of laelapine mites were observed and measured under a Leica DM 3000 LED microscope. The new species of laelapine mites reported in this paper was collected from the body surface of the red spiny rat ( Maxomys surifer Miller, 1900) in Jingha, Yunnan province, southwest China, on the thirteenth of May 2016. Those collected gamasid mites were preserved in vials with 70% ethanol and then mounted into glass slide specimens ( Pan and Deng, 1980 Deng et al. Gamasid mites on each host’s body surface, together with those scattered on the white cloth bag, were comprehensively collected over a large white tray with the help of a magnifier. Gamasid mites were conventionally collected from each host ( Guo et al. In our field investigations from 1990 to 2016, the rodents and some other small mammal hosts were mainly trapped with mousetraps (18 × 12 × 9 cm, Guixi Mousetrap Apparatus Factory, Guixi, Jiangxi, China) from different localities in Yunnan province, southwest China.Įvery captured host was placed in a pre-marked white cloth bag and transferred to a laboratory where all hosts were anesthetized and identified to species following Wilson and Reeder (2005) for mammalian taxonomy. This paper described the morphological features of this new species of laelapine mites. From the collected specimens of gamasid mites in the above field investigation, a new species associated with red spiny rat ( Maxomys surifer Miller, 1900) in Laelapidae was identified and named as Laelaps jinghaensis sp.

From 1990 to 2016, a series of field investigations on gamasid mites were made in Yunnan province, southwest China, and some results have been published, for example, the gamasid mites associated with the Asian house rat, Rattus tanezumi ( Huang et al. HFRS is widely distributed in China, and the southwest China is an important focus of the diseases ( Deng et al. In China, some species of gamasid mites (including laelapine mites) have been proved to be the potential vector and reservoir host of hemorrhagic fever with renal syndrome (HFRS) and they may play an important role in keeping and extending the foci of HFRS ( Baker et al. More than 20 kinds of zoonoses have been suspected to be related with gamasid mites ( Chen and Xu, 1995). Some ectoparasitic gamasid mites (including laelapine mites) may have potentials to transmit or preserve the pathogens of some zoonoses ( Zemskaya, 1973 Frolova, 1990). nuttalli) have been reported as attacking humans, resulting in varying degrees of dermatitis ( Sandosham and Nordin, 1967 Nadchatram and Ramalingam, 1974).
Ornithonyssus bacoti, Laelaps echidninus and L. The ectoparasitic gamasid mites on rodents are of medical significance and some of them ( i.e.
, 2017 ), plant debris, humus and even some warehousing goods (granary and flourmills), some gamasid mites (including laelapine mites in the family Laelapidae) can be ectoparasites, living on the body surface of vertebrates (mammals, birds, reptiles and amphibians, etc.) and even some other invertebrates ( Pan and Deng, 1980 Deng et al.
Apart from many species found in soil ( Khan et al.

As a big group of arthropod, gamasid mites usually involve a diverse variety of habitats with different living behaviors, such as free living, predation and parasitism, etc. Laelapidae Berlese is a large and cosmopolitan family of gamasid mites in the order Mesostigmata, subclass Acari in class Arachnida, including hundreds of species ( Pan and Deng, 1980 Deng et al.
