Illustrations, photographic and SEMimages are presented. A review of the diagnostic generic characters and a key to the species of Triplonychus and Globothorax from Brazil are also given. The genus Triplonychus was erected by Candeze (1860) to include ten species from South America basedon a combination of several non exclusive characters among which he emphasized the incomplete lateral carina of pro-thorax, the carinate ninth elytral interstice, the elongate antenna and the elytral and prothoracic shapes. He also cited two characters found exclusive to this genus: the tricuspid claws and the elytral striae with two or more rows of punctures.

A key is provided to the genera of Hydropsychidae of the southeastern United States, based primarily on wing characters. The subfamily Arctopsychinae (Trichoptera: Hydropsychidae) in North America contains the genera Arctopsyche McLachlan (4 spp.) and Parapsyche Betten (7 spp.; Morse 2009). Milne and Milne (1938) reviewed the North American species (as family Arctopsychidae), including descriptions of females of Arctopsyche grandis (Banks) and Parapsyche apicalis (Banks). Nimmo (1987) provided a review of the subfamily (as family Arctopsychidae), in which he described or redescribed males and females of the Canadian fauna;but the females of Parapsyche cardis Ross remained undescribed. Recent light trap and Malaise trap collections in the southern Appalachians, in association with the Great Smoky Mountains All Taxa Biodiversity Inventory and other surveys, yielded large numbers of both male and female arctopsychines. Examination of the females revealed that in addition to the females of Arctopsyche irrorata Banks and Parapsyche apicalis, an undescribed female form was collected.
查看更多>>摘要:The genus Stenolis Bates, 1864 is revised. New species described and illustrated include: Stenolis gilvolineata sp. nov., S. xanthostigma sp. nov., and S. giesberti sp. nov. from Panama; S. flavoguttata sp. nov. from Mexico (Veracruz and Chiapas); S.tavakiliani sp. nov. from Trinidad & Tobago, French Guiana, and Brazil (Amazonas and Rondonia); S. multimac-ula sp. nov. from Costa Rica S. marcelae sp. nov. from Brazil (Rondonia), Peru, and Bolivia; and S. nearnsi sp. nov. from Brazil (Amazonas and Para). New transfers proposed: Lepturges circumscripta (Bates, 1881) comb. nov. from Stenolis, and S. vigintiguttata (Bates, 1885) comb. nov. from Nyssodrysternum. New synonyms proposed include: Nyssodrys de-cemguttata Bates, 1885 and Nyssodrys calligrammavar. consobrina Melzer, 1934 = Stenolis calligramma (Bates, 1872). New country records: S. angulata (Fabricius, 1801) from Ecuador and Bolivia, S. calligramma (Bates, 1872) from Venezuela and Ecuador, and S. theobromae (Lara & Shenefelt, 1964) from Panama. A key for species identification is provided.

Later, Emeljanov (1972) established the genus Paralimnellus, designating P. cingulatus Dlabola as its type species. Hamilton (1975) and Webb & Heller (1990) treated Bubulcus as a separate genus. According to the Law of Priority of the ICZN (1999), two genus-group names, regardless of their rank within this category (genus or subgenus), cannot have the same type species. Therefore, Bubulcus and Paralimnellus are objective synonyms and the latter, younger, name is invalid. Recently, Nemesio (2007) proposed a new subgeneric name Dlabolasia to replace Bubulcus Dlabola, 1961, because thelatter is a junior homonym of Bubulcus Bonaparte, 1854. However, because Paralimnellus, an objective synonym of Bubulcus Dlabola, is an older available name, Paralimnellus must be retained as the replacement name for Bubulcus Dlabola. Thus, according toICZN Articles 23.3.5 and 60.1, Dlabolasia Nemesio should be treated as a junior objective synonym of Paralimnellus Emeljanov.

Individual species of this genus are externally similar, but can be separated by characters of the male genitalia. Bireta are mostly distributed throughout Southeast Asia, especially China (Kiriakoff, 1962; Kobayashi & Kishida, 2004; Kobayashi, Kishida & Min, 2008; Schintlmeister & Fang, 2001) and Thailand (Schintlmeister, 2007). In Sichuan Province, China in the springof 2010, the senior author collected a series of Bireta specimens which belongs to a new species, which is described below (acronyms for personal and institutional collections: AFM—Alessandro Floriani [Milan, Italy]; ASV—Aidas Saldaitis [Vilnius, Lithuania]; MWM/ZSM—Museum Thomas Witt [Munich, Germany]/Zoologische Staatssammlung, Munchen [Germany]; NRCV—Nature Research Centre [Vilnius, Lithuania]; PMM—Pavel Morozov [Moscow, Russia]).
查看更多>>摘要:A new species Nihonogomphus schorri Do & Karube, sp. nov. is described on the basis of male specimens collected from Huu Lien Nature Reserve, Lang Son Province, northern Vietnam. It is close to the Chinese species N bequaerti Chao, 1954 due to the similarity of hamules, anal appendages and vesicle, but is easy to-separate from that species by the vesica spermalis structure and body markings. During a field trip to Huu Lien Nature Reserve in Lang Son Province together with Matti Hamalainen in June 2008, a male specimen of a Nihonogomphus was collected. The first author observed also a female of the same species and managed to get some photographs, but unfortunately the dragonfly flew away before it could be collected. In May 2009, Hamalainen returnedto Huu Lien and he collected another male specimen on the same stream. This specimen was sent to the second author. Detailed study of these specimens has convinced the authors that it is a new Nihonogomphus species, which is described here.
