TÓM TẮT Đầm phá Tam Giang - Cầu Hai thuộc vào hệ đầm phá lớn nhất Đông Nam Á với diện tích 22.000 ha, đặc trưng cho vùng nhiệt đới gió mùa. Hệ đầm phá là vùng có giá trị về đa dạng sinh học, sinh thái và môi trường. Từ 08/2014 đến 07/2015 chúng tôi đã tiến hành thu thập vật mẫu, nghiên cứu và đã xác định được 24 loài động vật hai mảnh vỏ thuộc 19 giống, 11 họ, 7 bộ. Bổ sung thêm 6 loài thuộc 6 giống, 5 họ mới so với nghiên cứu trước đây. Đánh giá được đặc điểm phân bố về thành phần loài, mật độ cá thể động vật hai mảnh vỏ theo ba loại nền đáy (cát bùn, bùn cát và giá thể) và ba nhóm loài theo độ mặn (loài nước ngot, nước lợ và nước mặn). Abstract Tam Giang - Cau Hai lagoon is the largest in Southeast Asia. It is ​​22,000 hectares. Lagoon system is high of biodiversity, ecology and environment. According to a researcher from August 2014 to July 2015, we have identified 24 species of 19 genera of 11 families of 7 orders of bivalve (Bivalvia) to be living in Tam Giang - Cau Hai lagoon. The result added 6 new species of 6 genera of 5 orders compared with previous studies. We have appreciated distribution characteristics of species composition, density of individual animals bivalve in three categories substrata (silt, sand and substrate ) and three groups of species under salinity (species of freshwater, brackish and saltwater).

The genus Rapisma McLachlan, 1866 (montane lacewings) is a rare and little known group of the family Ithonidae (Insecta: Neuroptera). There have been 21 described species of Rapisma, and all of them are distributed from East Asia, South Asia and Southeast Asia. Here I report a new species of Rapisma from northwestern Yunnan, China, namely Rapisma weixiense sp. nov. The new species belongs to a group of Rapisma species with very short antennae.

The powder post beetles (Coleoptera: Bostrichidae) (except Lyctinae) of Yunnan Province in Southwest China are reviewed for the first time. Keys to twenty-six genera and fifty-two species from the Yunnan region are provided. One new genus and seven new species are described: Dinoderus (Dinoderastes) hongheensis sp. nov., Dinoderus (Dinoderastes) nanxiheensis sp. nov., Gracilenta yingjiangensis gen. nov., sp. nov., Calonistes vittatus sp. nov., Calophagus colombiana sp. nov., Xylodrypta guochuanii sp. nov. and Xylodrypta zhenghei sp. nov.. Fourteen species are recorded in China for the first time. The bostrichid fauna of Yunnan is compared with those of the neighbouring bio-geographically related Southeast Asian and Himalayan regions. The fauna has a close affinity with that of tropical Southeast Asia and a much weaker relationship with the Palearctic region. The differences with the Himalayas may reflect the separate evolutionary and complex geological history of the two areas.

Zatypota albicoxa (Walker) is newly recorded from Mt. Merapi, Java Is., Indonesia. This is the first record of Z. albicoxa from this part of the Oriental region and from the Southern Hemisphere, and the first record of the genus Zatypota from Southeast Asia. The Indonesian population of Z. albicoxa attacks a theridiid spider of the genus Parasteatoda, as do populations of Z. albicoxa in other regions. The spider is a new species, and is described under the name of Parasteatoda merapiensis.

The identity of the poorly known bagrid catfish Pseudomystus moeschii (Boulenger, 1890) is clarified and the species redescribed. Two new species of closely related bagrid catfishes are also described: Pseudomystus carnosus from the Way Seputih River drainage in the province of Lampung in the southern tip of Sumatra, and P. fumosus from the Pahang River drainage in eastern Peninsular Malaysia. Pseudomystus carnosus, P. fumosus and P. moeschii can be distinguished from congeners in having an enlarged posterior process of the post-temporal, presence of long hair-like epithelial projections on the skin and long tubular extensions of the sensory pores. Pseudomystus carnosus differs from the other two species in having a pointed (vs. rounded) tip of the nuchal shield, while P. fumosus differs from the other two species in having very well developed procurrent caudal rays which are sinuously curved along the anterior edges (vs. less developed procurrent caudal rays that slope evenly along the edges). A lectotype is designated for P. moeschii.
