The freshwater crabs of Macau, with the description of a new species of Nanhaipotamon Bott, 1968 and the redescription of Nanhaipotamonwupingense Cheng, Yang, Zhong & Li, 2003 (Crustacea, Decapoda, Potamidae).

Four species of freshwater crabs from three genera and two families (Cantopotamonhengqinense Huang, Ahyong & Shih, 2017, Nanhaipotamonguangdongense Dai, 1997, Nanhaipotamonmacau sp. n., and Somanniathelphusazanklon Ng & Dudgeon, 1992) are documented from Macau for the first time. One new species, Nanhaipotamonmacau sp. n., is described. The large flap on the male first gonopod terminal segment sets it apart from all other known congeners except N.wupingense Cheng, Yang, Zhong & Li, 2003, from Fujian. Characters of the carapace, male first gonopod and size, however, clearly differentiate these two species. Preliminary genetic studies also suggest that the two are not closely related. A neotype is designated for N.wupingense. The taxonomic status of Nanhaipotamonguangdongense is also discussed. Notes on the general biology and conservation status of these crabs are also included.

Detection of diverse viruses in alimentary specimens of bats in Macau.

Bats carry a variety of viruses, and some of them cause public health problems. Macau, which is famous for its gambling industry, has a complex population structure. The globalization in such an international metropolis has enhanced the chance of disease transmission. Therefore, surveillance of zoonotic viruses is necessary for the early warning of potential emerging infectious diseases. Here, we report the first surveillance of bat viruses in Macau. In this study, we collected 1004 samples involving 10 bat species from 7 sites from April 2015 to May 2016, and examined the presence of viruses using nucleic acid-based methods. Coronaviruses, adenoviruses and paramyxoviruses were detected in these samples, with a high prevalence of coronaviruses. While, none was positive for hepatitis A virus, hepatitis E virus or hantavirus. Co-infections are not common in those bat species, but coronavirus HKU6 and adenovirus can be found commonly occurred in Myotis ricketti.

The immature stages of Polypedilum (Pentapedilum) nodosum (Johannsen) and Polypedilum (Tripodura) masudai (Tokunaga) (Diptera, Chironomidae, Chironominae).

Based on associated material collected from Macau and Guangxi, the pupae and larvae of Polypedilum (Pentapedilum) nodosum Johannsen and P. (Tripodura) masudai Tokunaga are described completely for the first time. Both species are newly recorded from China. Characters for distinguishing the immature stage of these species from other allied Polypedilum species are noted. The previously recorded Polypedilum (Pentapedilum) 'K1' of Cranston  (1996) is shown to be P. nodosum. Information is provided on distribution and ecological tolerances.
