Sinarella Bryk, 1949 (Erebidae, Herminiinae) is a medium-sized, frail-bodied genus of moths that externally resembles other genera in the Zanclognatha generic complex. All known larvae of this genus feed on fresh leaves of moss. This genus is widely distributed from the Himalayas to Southeast Asia, Japan, Borneo, Sulawesi and New Guinea.A new species of the genus Sinarella Bryk, 1949, S. jinggangshana sp. nov., is described from Jinggangshan National Nature Reserve, Jiangxi Province, China. This species is morphologically similar to S. takasago Wu, Fu & Owada, 2013, S. cristulalis (Staudinger, 1892), S. formosensis Wu, Fu & Owada, 2013 and S. japonica (Butler, 1881), but differs in both external and male genitalia characters. Images of the male adults and their genitalia are provided.

The genus Phyllothelys Wood-Mason, 1876 (Mantodea, Hymenopodidae) includes 22 species, with China being a major diversity hotspot, hosting 15 species in four groups.A new species of this genus from Malipo, Yunnan, China, is described herein, namely Phyllothelys qingjinum sp. nov. A comprehensive taxonomic description, including geometric morphometric analysis, genetic distance and molecular phylogenetic analysis, were employed to illustrate its distinctiveness. This discovery fills a significant distribution gap for the P. werneri species group in southern Yunnan and emphasises the need for further exploration in this region.

Ischnothyreus Simon, 1893 is one of the most speciose genera of Oonopidae, with 124 extant species mainly distributed in the Old World. Currently, 27 species are known in China.A new species, Ischnothyreus ruyuanensis Tong, sp. n., is described from Guangdong Province, China. Morphological description and illustrations are provided.

The genus Anufrievia Dworakowska, 1970 is widely distributed in China, Korea, South Korea, Japan, Nepal, India, Thailand, Vietnam and Vietnam. This work reports on two new species of Anufrievia found at Bijie City and Shibing County, Guizhou Province, China.Two new species of the leafhopper genus Anufrievia Dworakowska, 1970 from Guizhou Province China are described and illustrated, i.e., A. crispata sp. nov. and A. confluensa sp. nov. A key to distinguish the Chinese species of the genus is given.

The informal Pyralis regalis complex, including species of the genus Pyralis Linnaeus, 1758 (Pyralidae), with a bright white or silvery pattern on the forewing, is reviewed, supplemented by observations of the externally distinguished P. perversalis (Herrich-Schäffer, 1849), which also exhibits similarities in genitalia and DNA barcodes. We describe Pyralis cardinalis Kaila, Huemer, Mutanen, Tyllinen & Wikström, sp. nov., based on specimens ranging from Denmark and Sweden in the West to Japan and South Korea in the East. A neotype is designated for the predominantly South European P. regalis [Denis & Schiffermüller], 1775. Lectotypes are designated for Asopia kacheticalis Christoph, 1893 and Pyralis princeps Butler, 1889. Pyralis regalis ssp. sagarrai Leraut, 2005 is considered a valid species, stat. nov.

Diodia kuntzei (Rubiaceae, Spermacoceae) is prostrate herb, rooting at the nodes, with reddish stems, multifimbriate stipules, axillary one-two-flowered inflorescences, corolla with filiform tube, and indehiscent fruit. The species is recorded for the first time for the state of Acre, where it was found in Alto Juruá region, municipality of Cruzeiro do Sul, in waterlogged habitat (07°33′32″S, 072°42′59″W). Images of the plant and comments on its habitat and distribution are provided.

Species of Diaporthe are important phytopathogens with wide host ranges and a global distribution. In the present study multi-locus phylogeny based on combined sequences of rDNA ITS, and partial sequences from the translation elongation factor 1-α (EF l-α), β tubulin (TUB) and calmodulin (CAL) genes, reveal three new species from fresh collections made in northern Thailand. The new species Diaporthe siamensis, D. thunbergii and D. pterocarpicola are introduced in this paper with full descriptions and comparison with similar taxa. Phomopsis pterocarpi which is epitypified and synonymised under Diaporthe pterocarpi is described based on a collection from northern Thailand. [ABSTRACT FROM AUTHOR]
