The genus Limonius Eschscholtz, 1829 was last treated as a whole by Candèze (1860). Since then, members have been placed in eight other genera: Cidnopus Thomson, 1859; Gambrinus LeConte, 1853; Elathous Reitter, 1890; Kibunea Kishii, 1966; Limoniscus Reitter, 1905; Nothodes LeConte, 1861; Pheletes Kiesenwetter, 1858; and Solskyana Dolin, 1978. Based on the examination of adult and larval characters, five genera are recognized: Elathous Reitter, 1890; Gambrinus LeConte, 1853; Limonius Eschscholtz, 1829; Pheletes Kiesenwetter, 1858; and Tetralimonius new genus. Limoniscus Reitter, 1905 and Sichuanelater Platia and Gudenzi, 2006 are new synonymies of Gambrinus LeConte, 1853; Micrathous Lane, 1971, Neoathousius Schimmel and Platia, 1991 and Solskyana Dolin, 1978 are all new synonymies of Limonius. A total of 84 new combinations are proposed: Nearctic: Elathous huguenini (Van Dyke, 1932) new combination; Gambrinus angulatus (Motschulsky, 1859) new combination; Gambrinus bicolor (Van Dyke, 1932) new combination; Gambrinus clypeatus (Motschulsky, 1859) new combination; Gambrinus confusus (LeConte, 1853) new combination; Gambrinus cribriceps (Van Dyke, 1943) new combination; Gambrinus crotchii (Horn, 1872) new combination; Gambrinus flavomarginatus (Knull, 1938) new combination; Gambrinus fulvipilis (Candèze, 1860) new combination; Gambrinus griseus (Beauvois, 1805) new combination; Gambrinus humidus (Lane, 1941) new combination; Gambrinus interstitialis (Melsheimer, 1846) new combination; Gambrinus lanchesteri (Lane, 1941) new combination; Gambrinus meridianus (Knull, 1947) new combination; Gambrinus mirus (LeConte, 1853) new combination; Gambrinus norahae (Al Dhafer, 2009) new combination; Gambrinus olentangyi (Knull, 1947) new combination; Gambrinus plebejus (Say, 1825) new combination; Gambrinus propexus (Candèze, 1860) new combination; Gambrinus rudis (Brown, 1933) new combination; Gambrinus rufihumeralis (Lane, 1941) new combination; Gambrinus seminudus (Van Dyke, 1932) new combination; Gambrinus shircki (Lane, 1965) new combination; Gambrinus sinuifrons (Fall, 1907) new combination; Gambrinus snakensis (Lane, 1965) new combination; Gambrinus stigma (Herbst, 1806) new combination; Gambrinus pictus (Van Dyke, 1932) new combination; Gambrinus ulkei (Horn, 1871) new combination; Gambrinus ursinus (Van Dyke, 1932) new combination; Gambrinus venablesi (Wickham, 1913) new combination; Limonius brevis (Van Dyke, 1932) new combination; Limonius sordidus (Van Dyke, 1932) new combination; Pheletes lecontei (Lane, 1971) new combination; Tetralimonius definitus (Ziegler, 1845) new combination; Tetralimonius humeralis (Candèze, 1860) new combination; Tetralimonius maculicollis (Motschulsky, 1860) new combination; Tetralimonius nimbatus (Say, 1825) new combination; Tetralimonius ornatulus (LeConte, 1857) new combination.

With the purpose of promoting nomenclatural stability, this paper addresses a number of errors, omissions, and controversial conclusions in a recent revision of the green lacewing genus Ceraeochrysa by Freitas et al. (2009). 1. Valid species, new combinations and synonymies: (a) We identified Ceraeochrysa chiricahuae Freitas and Penny (in Freitas et al. 2009), Chrysopa forreri Navás, and Chrysopa intacta Navás as subjective synonyms. Thus, Ceraeochrysa intacta, a species that was previously synonymized under Ceraeochrysa placita (Banks), becomes the valid name of the species [New status, new combination]. Chrysopa forreri is now synonymized under Cer. intacta, not Cer. placita [New synonymy]. And, Cer. chiricahuae becomes a junior synonym of Cer. intacta, not a valid species of Ceraeochrysa [New synonymy]. (b) We enumerate specific internal and external features of the Chrysopa cornuta Navás type that identify it as conspecific with Ceraeochrysa caligata (Banks), not Ceraeochrysa cincta (Schneider) as proposed by Freitas et al. (2009). Thus, Ceraeochrysa cornuta (Navás), which has priority, is reinstated as the valid name [Reinstated status, reinstated combination], and Ceraeochrysa caligata (Banks) is reinstated as a junior subjective synonym of Cer. cornuta, not a valid species [Reinstated synonymy]. (c) We provide documented evidence for reinstating three synonymies that Freitas et al. had reversed [Reinstated synonymies]: (i) Allochrysa parvula Banks is a junior subjective synonym of Ceraeochrysa lineaticornis (Fitch); (ii) Chrysopa columbiana Banks is a junior subjective synonym of Ceraeochrysa lineaticornis (Fitch); (iii) Chrysopa rochina (Navás) is a junior subjective synonym of Ceraeochrysa cincta (Schneider). 2. Generic assignments: (a) Visual evidence is provided for the placement of Ceraeochrysa laufferi (Navás) in Ungla. Therefore, Ungla laufferi (Navás) is reinstated as the valid name [Reinstated combination]. (b) We question Freitas et al.’s rationale for including Cer. placita (Banks) and Cer. intacta (Navás) (as Cer. chiricahuae Freitas and Penny) in the genus Ceraeochrysa; female and larval features of the two species differ markedly from those used to characterize Ceraeochrysa species. As an alternative that recognizes the uncertainty surrounding the generic placement of these species and that avoids additional, unnecessary name changes, we propose including the caveat “genus incertae sedis” with the names, as follows: Ceraeochrysa placita (Banks), genus incertae sedis, and Ceraeochrysa intacta (Navás), genus incertae sedis. 3. Type designations: (a) Errors concerning the Chrysopa furculata Navás type in the Muséum national d’Histoire naturelle, Paris (MNHN), are corrected, and doubts raised by Freitas et al. (2009) concerning the identification of this specimen as the holotype are removed. (b) The earlier designation of the Chrysopa rochina (Navás) type in the MNHN as the lectotype (not holotype) is verified.

World Fauna

In 1929 the writer described a British Columbian blackfly pupa with most unusual characteristics—unique among North American species in that the customary slender respiratory filaments are replaced by a closed, ringed, club-like horn with tw-o short, curved basal spurs. An examination of the literature at our disposal of the pupae known from Europe, Africa, Asia, Australasia and South America, indicates that a number of other unusual forms have been described, especially from Africa. Although the valid species of Simuliidae in the world fauna probably number more than three hundred and fifty, only about twelve of the known pupae of which we have records have breathing organs that are not of the filamentous type. In Northern Europe, Simulium equinum L., as described by Edwards and Puri, has breathing organs consisting of wide, thin-walled tubes, the basal and main branches of which form a ring on the thorax.

The Charipinae (Cynipoidea: Figitidae) are a small group of Hymenoptera biologically characterized as being secondary parasitoids of aphids and psyllids (Hemiptera) (Menke & Evenhuis, 1991).  A total of 281 species of Charipinae have been described since the first species was described by Westwood (1833) (including two fossils, one of them recently transferred in a new family, Protimaspidae). An updated world catalogue of the Charipinae is presented here, with 168 valid species: 111 included in Alloxysta Förster, 31 in Phaenoglyphis Förster, 13 in Dilyta Förster, 5 in Apocharips Fergusson, 4 in Thoreauana Girault, and 1 in Dilapothor Paretas-Martínez & Pujade-Villar, Lobopterocharips Paretas-Martínez & Pujade-Villar, Lytoxysta Kieffer and †Protocharips Kovalev. Eight species are considered as nomen nudum: Allotria fusca Dahlbom, 1842; Allotria thoreyi Dahlbom, 1842; Xystus xanthocephala Dahlbom, 1842; Allotria pusillina Giraud, 1877; Charips aphidiinaecida de Santis, 1937; Alloxysta keudelli Hedicke, 1927; Allotria amygdali Buckton, 1879 and  Allotria polita Provancher, 1881. Six as nomen dubium: Allotria (Allotria) recticornis atra Kieffer, 1902; Allotria (Allotria) brevicornis Kieffer, 1902;  Allotria (Allotria) orthocera Kieffer, 1902; Xystus femoralis Hartig, 1841; Charipsella laevigata Brèthes, 1913; Dilyta (Alloxysta) ignorata Kieffer, 1900. Three species are incertae sedis: Charips silvicola Belizin, 1928, Cynips atriceps Buckton, 1879 and Allotria (Allotria) testaceipes Kieffer, 1902. Two species are here synonymized: Alloxysta discreta (Förster, 1869) with A. ramulifera (Thomson, 1862) and A. megaptera (Cameron, 1889) with A. ruficollis (Cameron, 1883). Two species are raised from synonymy and considered here as valid species: Alloxysta cameroni (Cameron, 1883) and A. marshalliana (Kieffer, 1900). New names for species of Alloxysta are presented for homonimies with other Alloxysta species derived from the new combinations: Alloxysta ionescui Pujade-Villar & Ferrer-Suay new name for Alloxysta luteipes (Ionescu, 1969) n. comb., Alloxysta forshagei Pujade-Villar & Ferrer-Suay new name for Alloxysta bicolor (Ionescu, 1959) n. comb., and Alloxysta mattiasi Pujade-Villar & Ferrer-Suay new name for Alloxysta luteipes (Ionescu, 1959) n. comb. Also a new name to Phaenoglyphis is presented for the same reason before mentioned but without new combination: Phaenoglyphis hedickei Pujade-Villar & Ferrer-Suay new name for Phaenoglyphis longicornis Hedicke, 1928 and two new combinations are presented: Alloxysta rufa (Ionescu, 1959) n. comb and Alloxysta consobrina (Zetterstedt, 1838) Forshage n. comb. This catalogue includes: (i) a diagnosis of the subfamily with the most important taxonomic characters for species recognition, and illustrations of these characters; (ii) a key to genera; (iii) a list of all authors describing species of Charipinae; and (iv) a host table. The distribution of the Charipinae includes 106 Palaearctic species, 37 Nearctic, 11 Neotropical, 10 Afrotropical, 7 Oriental and 11 Australian. The species Alloxysta victrix (Westwood, 1833), A. fuscicornis (Hartig, 1841) and Phaenoglyphis villosa (Hartig, 1841) are cosmopolitan.

The Palearctic genus Cochylichroa Obraztsov & Swatschek, 1958, revised status (type species: Eupoecilia atricapitana Stephens, 1852), is redefined based on North American congeners, resulting in the following new combinations: Cochylichroa arthuri (Dang, 1984), new combination; C. atricapitana (Stephens, 1852), revised status; C. aurorana (Kearfott, 1907), new combination; C. avita (Razowski, 1997), new combination; C. foxcana (Kearfott, 1907), new combination; C. hospes (Walsingham, 1884), new combination; C. hoffmanana (Kearfott, 1907), new combination; C. temerana (Busck, 1907), new combination; and C. viscana (Kearfott, 1907), new combination. Monoceratuncus Razowski, 1992, is reported for the first time from the U.S.A. as Monoceratuncus lantana Pogue, new species. Mimcochylis Razowski, 1985, is reported for the first time from the U.S.A. as Mimcochylis fulvotinctana (Walsingham, 1884), new combination and senior synonym of M. planola Razowski, 1985, new synonym. One new species is described in Aethes Billberg, 1820 (i.e., A. triassumenta Pogue, new species), and one new combination (i.e., A. ringsi (Metzler, 2000), new combination, is proposed. Two other new combinations are proposed: Thyraylia wiscana (Kearfott, 1907), new combination, and Eupinivora parotanus (Razowski and Becker, 2010), new combination.

AbstractNeotherevella n.gen. is proposed as a replacement for Neothereva Kröber sensu Lyneborg (1976). Neothereva Kröber, 1912, is placed in new synonymy with Thereva Latreille, 1796, as the consequence of an overlooked designation of a type-species for Neothereva Kröber, 1912, by Kröber (1935). Neotherevella is fully described. Five specific names are placed in new combination with Neotherevella, which is known from Namibia, Mauritania, Algeria, Sudan, Egypt, Israel, Uzbechistan and Mongolia. It is demonstrated that two species described in combination with Neothereva by Zaitzev (1970) do not belong to Neotherevella.

Cirsium Undulatum

The morphology and specific differences of Cirsium undulatum (Nutt.) Spreng. and of C. flodmanii (Rydb.) Arthur are described and their Canadian distributions are reported in detail. The chromosome numbers are C. undulatum f. undulatum and f. album Farwell, 2n = 26; C. flodmanii f. flodmanii and f. albiflorum D. Löve, 2n = 22. The origin of four North American species of Cirsium that do not follow the world-wide base number 17 is discussed; it is postulated that reduction in number has occurred by translocations. The chromosomes of species with reduced numbers are larger than those of the unreduced species but the total length of the chromosomes of both groups is approximately the same.

Sequence data (COI-5P and rbcL) for North American members of the tribe Pterosiphonieae were compared with collections from around the world. Phylogenetic analyses resolved Pterosiphonia as polyphyletic and many species required transfer to other genera. In our analyses Pterosiphonia sensu stricto included only the type species P. cloiophylla (C. Agardh) Falkenberg and P. complanata (Clemente) Falkenberg, as well as the South African species P. stegengae sp. nov. A new genus, Xiphosiphonia gen. nov., was described for X. ardreana (Maggs & Hommersand) comb. nov., X. pennata (C. Agardh) comb. nov., and X. pinnulata (Kützing) comb. nov. Some Asian, European and North American species previously attributed to Pterosiphonia were transferred to Symphyocladia including S. baileyi (Harvey) comb. nov., S. dendroidea (Montagne) comb. nov., S. plumosa nom. nov. (for P. gracilis Kylin), and S. tanakae (S. Uwai & M. Masuda) comb. nov. We also described two new North American species, Symphyocladia brevicaulis sp. nov. and S. rosea sp. nov. Other species formed a well-supported clade for which the genus name Polyostea Ruprecht was resurrected. Included in Polyostea were P. arctica (J. Agardh) comb. nov., P. bipinnata (Postels & Ruprecht) Ruprecht, P. hamata (E.S. Sinova) comb. nov., and P. robusta (N.L. Gardner) comb. nov.
