The thread-legged bug genus Onychomesa Wygodzinsky 1966 (Hemiptera: Reduviidae: Emesinae: Emesini, formerly Metapterini) and its three described species are reviewed. The Sri Lankan species Ischnonyctes alatus Distant 1903 is resurrected from the synonymy with Schidium marcidum (Uhler, 1896) and transferred to Onychomesa, and O. susainathani Wygodzinsky, 1966 is considered a junior synonym of this species, resulting in the following taxonomic changes: O. alata (Distant 1903), stat. rev. et comb. nov. = O. susainathani Wygodzinsky 1966, syn. nov. The lectotype of I. alatus is designated. A new species, O. schuhi Chen et Cai, sp. nov., is described from Hainan Island, southern China. An updated key to the species of Onychomesa is provided. The species is registered in ZooBank (http://zoobank.org/8F582127-631F-4CD9-9E02-C3CD14AA52DC). [ABSTRACT FROM AUTHOR]

A new species, Momonides neolandbergi Li & Guo sp. nov. is described in detail, which is the fifth species all over the world in Momonidinae Lundblad, 1941, Momoniidae K. Viets, 1926. The family and subfamily are newly recorded for Chinese fauna. The new species are recorded by camera, optical microscope, and scanning electron microscope.

Previously, only three species of the genus Neurigona Rondani of the subfamily Neurigoninae were known from Yunnan Province. Here, we reviewed the species of Neurigona from Yunnan and added the following seven new species: N. apicilata sp. nov., N. basicurva sp. nov., N. brevidigitata sp. nov., N. convexa sp. nov., N. huanglianshana sp. nov., N. quadrimaculata sp. nov., and N. ventriprocessa sp. nov. All seven new species are sympatric and were collected from below a reservoir in the Huanglianshan Nature Reserve in Yunnan using three Malaise traps in 2019. This suggests a very high species richness in the Yunnan fauna. A key to the species of Neurigona from Chinese mainland is provided. [ABSTRACT FROM AUTHOR]

Rhagophthalmus Motschulsky, 1854 is the most speciose genus in Rhagophthalmidae, distributed in the region encompassing South, East, and Southeast Asia. Here, we describe R. nanus sp. nov. from the Houaphanh Province of eastern Laos, which represents the smallest known species in Rhagophthalmus and one of the smallest in Rhagophthalmidae. We compare it with the morphologically similar and geographically close congeners and provide a preliminary identification key to adult males of Rhagophthalmus species from mainland Southeast Asia. Additionally, we discuss the morphology and variability of male genitalia within Rhagophthalmus. [ABSTRACT FROM AUTHOR]

The species belonging to the Strongylophthalmyia coarctata subgroup of the S. punctata group (Diptera: Brachycera: Strongylophthalmyiidae) from China are reviewed. Six species are recognized, including three new species: S. corniculata sp. nov., S. flagellicornis sp. nov., and S. tangwangana sp. nov. Strongylophthalmyia narwhal Evenhuis, 2020 and S. raricornis Shatalkin, 1981 are recorded from China for the first time, and S. raricornis is also recorded from South Korea for the first time. An identification key to the Asian species of the S. coarctata subgroup is provided. [ABSTRACT FROM AUTHOR]

Two new species, Helochares guoi Yang & Jia, sp. nov. and Helochares distinctus Jia & Tang, sp. nov., are described. Two species are recorded for the first time from China: Helochares negatus Hebauer, 1995 from Yunnan, and Helochares minusculus d'Orchymont, 1943 from Guangdong. Additional faunistic data from China are provided for the following species: Helochares hainanensis Dong & Bian, 2021, Helochares nipponicus Hebauer, 1995, Helochares sauteri d'Orchymont, 1943, Helochares densus Sharp, 1890, Helochares lentus Sharp, 1890, Helochares neglectus (Hope, 1854) and Helochares anchoralis Sharp, 1890. The Chinese fauna of Helochares comprises 16 species, 11 of which are illustrated in this contribution. Helochares crenatus Régimbart, 1921 is removed from the Chinese fauna. [ABSTRACT FROM AUTHOR]

The south-east coastal area of Fujian, China, belongs to the Oriental Realm, and is characterized by a high insect species richness. In this work, a new species of Hymenopteran parasitoid, Glyptapanteles gigas Liang & Song, sp. nov. found in Jinjiang within hosts of caterpillars Macrobrochis gigas (Lepidoptera: Arctiidae), is described and illustrated, with differences from similar species. Additionally, we presumed that both parasitoid and host species play very important role in the coevolution and tritrophic interaction between plants, phytophagous insects, and their parasitoids, because these insects probably broke the sporangia and made contributions to their colonization, or some spores were spread for long distances by adult moths after their emergence, or some parasitoids were attracted by the eggs and larvae of these caterpillars, which was also thought to be helpful to spread of spores.

Teloganopsis puigae n. sp., a new species of Ephemerellidae from a Dipterocarpacea forest of Borneo, is described. Teloganopsis was considered as a monotypic genus for a long time, but a recent new systematic concept reveals that it encompasses 14 species. In order to know the phylogenetic position of Teloganopsis puigae n. sp. within the Teloganopsis genus, a cladistic analysis is also performed. Teloganopsis maculocaudata (Ikonomov, 1961) is removed from synonymy with T. mesoleuca (Brauer, 1857). [ABSTRACT FROM AUTHOR]
