Three new species of the Oriental bamboo delphacid planthopper genus Kakuna Matsumura (Hemiptera: Fulgoromorpha: Delphacidae: Delphacinae: Delphacini), K. lii sp. nov. (Guizhou: Jiangkou, Suiyang, Daozhen), K. nonspina sp. nov. (Guizhou: Jiangkou, Leishan) and K. zhongtuana sp. nov. (Guizhou: Leishan, Suiyang, Daozhen, Libo), are described and illustrated from southwestern China. The generic characteristics are redefined. A checklist and a key to species of genus Kakuna are provided.

This study describes a new species of the genus Leptobrachella, Leptobrachella suiyangensissp. nov. from the Huoqiuba Nature Reserve, Suiyang County, Guizhou Province, China, based on morphological data and phylogenetic analyses (16S rRNA mtDNA). The new species can be distinguished from other congeners by the molecular divergence and by a combination of morphological characters, including body size, dorsal and ventral patterns, dorsal skin texture, size of the pectoral and femoral glands, degree of webbing and fringing on the toes and fingers, dorsum coloration, and iris coloration in life. Currently, the genus Leptobrachella contains 75 species, 21 of which are found in China, including seven species reported from Guizhou Province. The uncorrected sequence divergence percentage between Leptobrachella suiyangensissp. nov. and all homologous DNA sequences available for the 16S rRNA gene was found to be >4.7%. The new record of the species and its relationships with others in the same genus imply that species distribution, habitat variation, environmental adaptation, and diversity of the genus Leptobrachella in southwest China need to be further investigated.

A new species of the genus Cardamine Linn.(Brassicaceae), Cardamine kuankuoshuiense M. T. An, Yun Lin & Y. B. Yang is described, illustrated and photographed from Suiyang County, Guizhou Province, SW China. This species was found growing on damp precipice or between moist rock crevices in evergreen broad-leaved forests or mixed needle-leaved and evergreen broad-leaved forests in carst mountains at altitudes of 1400–1430 m. The new species is related to both Cardamine griffithii J. D. Hook. & Thomson and Cardamine multijuga Franch., but differs from both of them by herbs 15–25 cm tall, scapose, with a few stolons, stems terete, cauline leaves absent.

Lactifluus is a distinct genus of milkcaps, well known as ectomycorrhizal fungi. The characteristics of the genus Lactifluus include grayish-yellow, orange to orange-brown, or reddish-brown pileus, white latex from the damaged lamellae, discoloring to a brownish color, reticulate spore ornamentation, lampropalisade-type pileipellis, and the presence of lamprocystidia. Guizhou Province is rich in wild mushroom resources due to its special geographical location and natural environment. In this study, three novel Lactifluus species were identified through the screening of extensive fungal resources in Suiyang County, Guizhou Province, China, sampled from host species of mostly Castanopsis spp. and Pinus spp. Based on critical morphology coupled with nuclear sequences of genes encoding large subunit rRNA, internal transcribed spacer, and RNA polymerase II, these new species, Lactifluus taibaiensis, Lactifluus qinggangtangensis, and Lactifluus jianbaensis, were found to belong to Lactifluus section Lactifluus. A comparison with closely related species, Lactifluus taibaiensis was distinguished by its lighter-colored pileus, different colors of lamellae, and more subglobose basidiospores; Lactifluus jianbaensis was identified by the height of the spore ornamentation and its subglobose basidiospores; and Lactifluus qinggangtangensis was characterized by having smaller basidiospores, ridges, and pleurolamprocystid.

Sweltsa is a genus of green stoneflies in the family Chloroperlidae and is distributed throughout the Nearctic and East Palaearctic Regions. As they are sensitive to pollutants, they are often used as an indicator species for determining the quality of water bodies. There are around 57 species of this genus worldwide and 11 of those have been identified from China. A new species of the Alloperlini genus Sweltsa Ricker, 1943, Sweltsa ligula Rehman, Huo & Du sp. n. is described from Kuankuoshui National Natural Reserve, Suiyang County, Guizhou Province, southwest China. This is the first report of the family Chloroperlidae from Guizhou Province. Diagnosis, description of male, female and nymph, illustration of terminalia and similarities with closely-related species are provided and discussed.
