“…40 new species, e.g. Kuwayama (1962), Flint (1964), Asp€ ock et al (1980, 2001a), Vshivkova (1985), Whiting (1991), Hayashi and Suda (1995), Theischinger (2000), Liu and Yang (2006a,b), Liu et al (2008), Contreras-Ramos (2008), and Price et al (2012). Considering the extinct Sialidae, the earliest definite fossil is †Dobbertinia reticulata Handlirsch, 1920 from the Lower Jurassic of Germany, which was originally placed in Mecoptera (Handlirsch, 1920) and was transferred to Sialidae by Ansorge (2001).…”

Sialidae (alderflies) is a family of the holometabolous insect order Megaloptera, with ca. 75 extant species in eight genera distributed worldwide. Alderflies are a group of “living fossils” with a long evolutionary history. The oldest fossil attributed to Sialidae dates back to the Early Jurassic period. Further, the global distribution of modern‐day species shows a remarkably disjunctive pattern. However, due to the rareness of most species and scarcity of comprehensive taxonomic revisions, the phylogeny of Sialidae remains largely unexplored, and the present classification system is in great need of renewal. Here we reconstruct the first phylogeny for Sialidae worldwide based on the most comprehensive sampling and broadest morphological data ever presented for this group of insects. All Cenozoic alderflies belong to a monophyletic clade, which may also include the Early Jurassic genus †Dobbertinia, and the Late Jurassic genus †Sharasialis is their putative sister taxon. Two subfamilies of Sialidae are proposed, namely †Sharasialinae subfam. nov. and Sialidinae. Austrosialis is the sister of all other extant genera, an assemblage which comprises three monophyletic lineages: the Stenosialis lineage, the Ilyobius lineage, and the Sialis lineage. The revised classification of Sialidae is composed of 12 valid genera and 87 valid species. Ilyobius and Protosialis are recognized as valid generic names, while Nipponosialis is treated as a synonym of Sialis. Reconstruction of the ancestral area proposes a global distribution of alderflies in Pangaea before their diversification. The generic diversification of alderflies might have occurred before the breakup of Pangaea, but the divergence of some lineages or genera was probably promoted by the splitting of this supercontinent.

“…Species identification and the determination of postembryonic developmental stage and sex were performed under a stereoscopic microscope (Olympus SZ61, Tokyo, Japan) by TI, using Ishikawa et al (2012), Hayashi and Miyamoto (2005), Yasunaga et al (1993), and Yasunaga et al (2001) as primary references, together with the original descriptions and/or redescriptions of each species, as necessary. For accurate identification, observations of the genitalia, if needed, were made under the stereoscopic microscope and an optical microscope (Olympus BX41) after dissection.…”

“…The approximately 1,300 known heteropteran species of Japan are estimated to represent more than 80% of the possible total number of species (Hayashi and Miyamoto 2005, Ishikawa et al 2012). Of these, 348 species have been recorded in the administrative districts of Tokyo from coastal plains to mountainous regions (excluding islands belonging to the metropolis), and approximately 30% of the 348 species have been found in central Tokyo (Ito et al 2014).…”

BackgroundThe Heteroptera, or true bugs, forms one of the major insect groups with respect to the very diverse habitat preferences, including both aquatic and terrestrial species, as well as a variety of feeding types. The first comprehensive inventory of the Heteroptera at Komaba Campus of the University of Tokyo, or an urban green space in the center of the Tokyo Metropolis, Japan, was conducted.New informationA total of 115 species in 29 families of the suborder Heteroptera were identified. The area had a high species richness compared with other urbanized and suburbanized localities in Tokyo. The campus is found to show a substantial difference in heteropteran species compositions, despite being close to the other localities surrounded by highly urbanized zones in central Tokyo.

“…Only one male from Vietnam and one female from China are known for this new species. In the monograph of Chinese Megaloptera (Yang & Liu ), the female of this new species was identified to be Nipponosialis kumejimae (Okamoto, ) (Current name is Sialis kumejimae Okamoto, ), which is mainly distributed in Taiwan and Ryukyus (Hayashi & Suda ), although this female was collected from south of mainland China. After finding of male of the new species, we consider that this Chinese female was mis‐identified and is likely to be conspecific with the Vietnamese male because of their identical appearance and close geographical distributions.…”

“…Besides the species listed in this catalog, another Sialis species was recently described from Korea (Jung & Bae ). The taxonomy of Sialis has been well studied with almost all known species described or re‐described by modern approaches based on several revisionary works, for example Ross (), Vshivkova (), Hayashi and Suda (), Aspöck et al . (, ) and Yang and Liu ().…”

The alderfly genus Sialis is the most species-rich group of the family Sialidae. However, discovery of new Sialis species is becoming difficult because of previous good faunal exploration. In this paper, we describe two new Sialis species from the southern part of East Asia, S. australis and S. jiyuni, based on materials from historical and recent collections. These two species are closely related to the insular species S. kumejimae and are among the early diverged species within Sialis. Presently, 32 species of Sialis are recorded from Asia. A key to all the Sialis species from Asia is provided.
