The purpose of this application, under Articles 29 and 55.3.1 of the Code, is to remove homonymy between the family-group names RHOPAlURINAE Bucherl, 1971 (family BUTHIDAE, Scorpiones) and RHOPAlURIDAE Stunkard, 1937 (phylum Orthonectida) by changing the spelling of the junior homonym. To date both names have had little use, but the name RHOPAlURINAE is likely to be used in future taxonomic revisions of the BUTHIDAE. Before this junior homonym becomes adopted in the literature, it is proposed that the whole of the generic name of the type genus (Rhopalurus Thorell, 1876) of RHOPAlURINAE should be used to form the emended name RHOPAlURUSINAE Bucherl, 1971, leaving the orthonectid senior homonym (RHOPAlURIDAE Stunkard, 1937) unchanged.
Two New Species of Myodocha (Lygaeoidea: Rhyparochromidae: Myodochini) with a Key to Species
Annals of the Entomological Society of America, 2005
Two new species of Myodocha, Myodocha parcicoma Cervantes and Myodocha unispinopilosa Cervantes, are described from Mexico and South America. A key to the 10 known species and new geographic records for the genus are provided. Species in this genus can be separated into two groups by the presence or absence of hairs on the neck region; other characters used to differentiate the species are length of rostrum, presence of tibial spines on forelegs in males; and shape and number of spines on forefemora of males and females. The last two characters (i.e., shape and number of spines on forefemora), although variable, show diverse patterns. KEY WORDS Heteroptera, Myodocha, Rhyparochromidae, Mexico THE GENUS Myodocha Latreille is differentiated from other Myodochini by the presence of a long neck, and posterior margins of ocelli are anterior of the posterior margins of the eyes. Oliver (1811) described M. serripes, which is distributed throughout the United States. Stål (1862) described M. giraffa in 1862, and M. longicollis and M. unispinosa in 1874, all from Mexico. Distant (1882) described M. intermedia and M. inermiba. Harrington (1980), in her review of the Myodochini of the world, included eight species in the genus Myodocha. Later, Harrington (1987) transfered M. inermiba to Dushinckanus. Barber (1954) described M. fulvosa from Cuba, and Slater (1998) described M. froeschneri from the West Indies and suggested that a review of the genus was needed. Several hemipterologists have studied this genus and have mentioned the difÞculty of separating some of the species. Thanks to the large amount of material deposited in Coleccion Nacional de Insectos in Mexico City and a study of rhyparochromids associated with Þgs in Mexico, we have found variability within the species, discovered two undescribed species, and found several characters that are useful at the species level. Materials and Methods Most of the material studied is deposited in Coleccion Nacional de Insectos in Mexico City, Instituto de Biologia, U.N.A.M. (CNIN), but several other collections were checked during this study, including The American Museum of Natural History (AMNH); Richard M. Baranowski Collection, Homestead, FL (RMB); Coleccion Entomologica Instituto de Ecologia, A.C. (IEXA); Florida State Collection of Arth-ropods (FSCA); Natural History Museum London (BMNH); National Museum of Natural History, Washington, DC. (NMNH); and James A. Slater Collection, Storrs, CT (JAS). A few specimens from Universidad Central de Venezuela, Maracay (UCV), and from Universidad Catolica, Quito, Ecuador (UCQE) also were checked. Measurements are base on 10 individuals and are given in millimeters Ϯ SD. Results Myodocha parcicoma new species (Figs. 1, 3H, 4H)

The new genus Scudderocoris (Heteroptera: Rhyparochromidae: Rhyparochromini) is established to accommodate Caridops albomarginatus, a species known from China, Japan, and South Korea: Scudderocoris albomarginatus (Scott, 1874) comb. nov. The species is redescribed and photographs of the adult male and its genitalia are provided. The finding of a male specimen labeled from South America is intriguing. To evaluate if this species could find suitable climatic conditions in the Neotropics, we performed a Species Distributional Model (SDM), based on native distribution records, and compared the bioclimatic variables between the native range and the area where the specimen was supposedly collected. Our conclusion that the specimen was mislabeled, shows that SDM can be a useful tool in detecting collection label biases.
Abstract. The purpose of this application, under Article 23.9.3 of the Code, is to conserve the widely used specific name Elasmucha dorsalis (Jakovlev, 1876) for a species of subsocial acanthosomatid bug from East Asia. The name is threatened by the senior subjective synonym Elasmucha vicina (Uhler, 1861), which has seldom been used since its first publication. Therefore, precedence of the name Elasmucha dorsalis (Jakovlev, 1876) is proposed.

Although 17 species of Rhopalosiphum (Hemiptera: Aphididae) are currently recognized, 85 taxonomic names have been proposed historically. Some species are morphologically similar, especially alate individuals and most synonymies were proposed in catalogues without evidence. This has led to both confusion and difficulty in making accurate specieslevel identifications. In an attempt to address these issues, we developed a new approach to resolve synonymies based on linear discriminant analysis (LDA) and suggest that this approach may be useful for other taxonomic groups to reassess previously proposed synonymies. We compared 34 valid and synonymized species using 49 measurements and 20 ratios from 1,030 individual aphids. LDA was repeatedly applied to subsets of the data after removing clearly separated groups found in a previous iteration. We found our ‡ § | | This is an open access article distributed under the terms of the CC0 Public Domain Dedication. characters and technique worked well to distinguish among apterae. However, it separated well only those alatae with some distinctive traits, while those apterate which were morphologically similar were not well separated using LDA. Based on our morphological investigation, we transfer R. arundinariae (Tissot, 1933) to Melanaphis supported by details of the wing veination and other morphological traits and propose Melanaphis takahashii Skvarla and Miller as a replacement name for M. arundinariae (Takahashi, 1937); we also synonymize R. momo (Shinji, 1922) with R. nymphaeae (Linnaeus, 1761). Our analyses confirmed many of the proposed synonymies, which will help to stabilize the nomenclature and species concepts within Rhopalosiphum.
Case 3584 Erythemis Hagen, 1861: proposed precedence over Lepthemis Hagen, 1861 (Insecta, Odonata)
The purpose of this application, under Articles 23.9.3 and 81.1 of the Code, is to conserve the widespread usage of the generic name Erythemis Hagen, 1861 for a group of common dragonflies from the New World over the simultaneously published nominal genus Lepthemis Hagen, 1861, selected to take precedence by the First Reviser action (Article 24.2), whenever these names are considered to be synonyms. This proposal seeks to achieve the least change in the nomenclature of the species currently placed in these two genera, in strict accordance with Principle 4 of the Code.
