Update to the registers of family-group and genusgroup taxa of aphidoidea (Hemiptera, Sternorrhyncha)

P. 1-23Errors and omissions to the Registers of family-group and genus-group taxa of Aphidoidea (Hemiptera Sternorrhyncha) are ammended and new information made available in 2011, 2012 and 2013 is added. The former data are presented in two lists, one for minor corrections, and the other for corrections with important nomenclatural or taxonomic significance. The additions are presented in a third list. Also, Neoaulacorthum Lee (W.) & Lee (S.), 2011 is shown to be a synonym of Pseudomegoura Shinji, 1928, and the consequent combinations are presented: Pseudomegoura magnoliae (Essig & Kuwana, 1918) comb. nov., and P. nipponica (Essig & Kuwana, 1918) comb. nov.S

Molecular data and species diagnosis in Essigella Del Guercio, 1909 (Sternorrhyncha, Aphididae, Lachninae)

Morphological and molecular data are used to describe three new species of Essigella (Sternorrhyncha: Aphididae: Lachninae): Essigella domenechi sp. n., Essigella gagnonae sp. n., and Essigella sorenseni sp. n.; and to re-establish as valid Essigella patchae Hottes, 1957, stat. n., until now considered a synonym of E. pini Wilson, 1919. The catalogue of Essigella species is updated. This study highlights the need and utility to use discreet DNA characters in aphid species diagnoses

The Bhutan pine aphid Pseudessigella brachychaeta Hille Ris Lambers (Hemiptera: Aphididae: Lachninae) from India reveals the hitherto unknown oviparous female and dwarfish male

Here we describe the presence of the monotypic and poorly known aphid genus Pseudessigella Hille Ris Lambers (Hemiptera: Aphididae: Lachninae) in India. So far, the genus has only been known from Punjab, Pakistan. Representatives of P. brachychaeta Hille Ris Lambers were collected from Pinus wallichiana A.B. Jacks. in the Yousmarg region of the state of Jammu and Kashmir in India. Hitherto unknown oviparous females and dwarfish males, the latter reported in Eulachnini for the first time, are described and illustrated. The male’s antennal sensilla and genitalic morphology are additionally studied and presented using Scanning Electron Microscopy. Notes on the biology, distribution, and previously overlooked generic features are given. We provide morphological identification keys to the genera of the tribe Eulachnini and to the species of aphid living on P. wallichiana

\u3ci\u3ePhorodon cannabis\u3c/i\u3e Passerini (Hemiptera: Aphididae), a newly recognized pest in North America found on industrial hemp

Phorodon cannabis Passerini (Hemiptera: Aphididae: Macrosiphini) is reported for the first time as a pest of Cannabis L. crops in North America. The insect has been confirmed from fields of industrial hemp in Colorado and Virginia and has been found present within greenhouses in at least several American states and one Canadian province. The generic position of the aphid species is discussed and other known members of the genus are ruled out. Phorodon cannabis is placed in genus Phorodon Passerini and subgenus (Diphorodon Börner). Phorodon persifoliae Shinji is transferred to Hyalopterus Koch as a nomen dubium

Type species of genera in Aphididae (Hemiptera Sternorrhyncha) with two new generic synonymies

P. 65-68The aphidologist community attending the Seventh International Symposium on Aphids in Fremantle (Western Australia, 2005) entrusted to us the preparation of a Part of the List of Available Names in Zoology devoted to the aphid genus-group taxa names, and this to be presented at the subsequent aphid symposium. During the course of our work (Nieto Nafría et al. 2009), we checked each genus to make sure its type species designation conformed to the International Code of Zoological Nomenclature (International Commission on Zoological Nomenclature 1999) ―henceforth The Code and The Commission―, and that these designations were correctly represented in the literature, especially the two most recent taxonomic catalogues (Eastop & Hille Ris Lambers 1976; Remaudière & Remaudière 1997). Previous authors have used most of the procedures of type fixation enumerated in The Code, The Commission itself has used its Plenary Powers to fix six type species, and 11 genus-group names remain without types (Table 1). In the recent aphid taxonomic catalogues (Eastop & Hille Ris Lambers op. cit.; Remaudière & Remaudière op. cit.), we found three errors caused by mistakes propagated in the literature and two errors caused by incorrect application of Article 11 of The Code. We have also found that in the case of 11 names, the criteria of Article 70.3 of The Code were not met, and regardless, earlier editions of The Code did not allow type designations of that kind (see the last paragraph of the example in Article 70.3). This article corrects the five errors and conforms the 11 aphid type species designations to the nomenclatural standards of The Code.S

Studies on Species of the Aphid Genus Cinara on Pinus Edulis and Pinus Monophylla

102 p.Thesis (Ph.D.)--University of Illinois at Urbana-Champaign, 2003.Cinara are aphids (Hemiptera: Aphididae: Lachninae) that feed exclusively on conifers of the Cupressaceae and Pinaceae. They are speciose and particularly diverse in North America. Their phylogenetics is completely unknown and they historically have been treated based on the taxonomy of their hosts. They are also known to specialize on particular woody parts of their hosts (roots, branches, shoots, etc.). In Chapter 1, using cytochrome oxidase I DNA sequences, I performed molecular phylogenetic analysis of Cinara species feeding on pinyon pines and determined that switching hosts played a key role in the speciation of the genus. This was reflected in the fact that species sharing a common feeding site on different hosts were more closely related than those sharing the same host but at different feeding sites. This study also revealed that Cinara wahtocla Hottes represented two species on the two different pinyon pine species, Pinus edulis Englem. and P. monophylla Torr. & Frem. In Chapter 2, I compared the morphology of C. wahtolca, C. edulis (Wilson) and C. terminalis (Gillette and Palmer) feeding on the two pinyons. All three species were larger when on P. monophylla, but the rostrum of C. terminalis showed the reverse trend, being shorter when feeding on P. monophylla than when on P. edulis. The analysis of rostrum length showed that this particular character can be independent of aphid size. In Chapter 3, I used principal components analysis to determine the validity of several pinyon-feeding species. I concluded by synonymizing five species. Finally, in Chapter 4, I provided a new technique for extracting DNA from aphids which preserves the cuticle intact for slide-mounting. I presented this technique in the context of DNA taxonomy of aphids, a tool that should be developed and will prove to be very useful.U of I OnlyRestricted to the U of I community idenfinitely during batch ingest of legacy ETD
