The aim of this study is to deepen the knowledge of five poorly studied Longitarsus species in order to elucidate their taxonomic position within the genus. For each of them further diagnostic characters and many new collecting localities are supplied. One new synonymy and one change of status are proposed: L. callidus Warchalowski 1967 = L. aphthonoides Weise 1887 syn. nov., and L. lateripunctatus personatus Weise 1893 is raised to valid species. The morphologically similar L. curtus (Allard 1860) and L. monticola Kutschera 1863 are also examined, providing new male and female diagnostic characters for their identification, as well as several European and Italian new collecting localities.

AbstractThe 75 valid species of the genus Bursaphelenchus are listed together with their synonyms. Diagnostic characters and their states are discussed and illustrated. Tabular and traditional text keys are provided for the genus. Two new subspecies are proposed to distinguish populations of B. piniperdae and B. poligraphi, as described by Rühm (1956), from the original descriptions of these species published by Fuchs (1937). Known records of Bursaphelenchus species with their associated natural vectors, plants and plant families are given. Dendrograms of species relationships (UPGMA, standard distance: mean character difference) based on combined taxonomic characters and also on spicule characters only, are provided. Discussion as to whether the species groups are natural or artificial (and therefore purely diagnostic) is based on their relationships in the dendrogram and the vector and associated plant ranges of the species. Of the six species groups distinguished, two appear to represent natural assemblages, these being the xylophilus-group (with ten species) and the hunti-group (seven species), of which two, B. cocophilus and B. dongguanensis, form the cocophilus-cluster which is separated on the dendrogram from the main clusters. The remaining four species groups appear to be artificial and purely diagnostic in function, namely the aberrans-group (four species); the eidmanni-group (six species); the borealis-group (five species), and the piniperdae-group (43 species). Two new subspecies, both in the piniperdae-group, viz. B. piniperdae ruehmpiniperdae n. subsp. and B. poligraphi ruehmpoligraphi n. subsp., are proposed and diagnosed from B. piniperdae piniperdae and B. poligraphi poligraphi the respective type subspecies. Bursaphelenchus dongguanensis is regarded as being a valid member of the genus and its transfer to Parasitaphelenchus is rejected.

AbstractThe species of the genus Macrophya Dahlbom (Tenthredininae) of North America are revised. Forty-six species and two subgenera are recognized, Macrophya s. str. with 45 species, and Pseudomacrophya Enslin with a single species. The subgenus Paramacrophya Forsius is newly synonymized with Macrophya s. str. Eleven species are described as new: amediata, epinolineata, macgillivrayi, masneri, masoni, mensa, nirvana, phylacida, senacca, serratalineata, and smithi; and the following new synonymy proposed: albomaculata (Norton) = contaminata Provancher, errans Rohwer, and fuscoterminata Rohwer; bifasciata (Say) = pulcherrima Kirby; cassandra Kirby = albilabris Harrington, bellula MacGillivray, and externiformis Rohwer; flavolineata (Norton) = confusa MacGillivray, crassicornis Provancher, (?) lineata Norton, and proximata Norton; flicta MacGillivray = fistula MacGillivray; fuliginea Norton = castanea Rohwer; fumator Norton = pumila Norton, and subviolacea Cresson; mixta MacGillivray = bilineata Dyar; nigra (Norton) = minuta MacGillivray; oregona Cresson = obaerata MacGillivray, and oregona var. dukiae Ross; pannosa (Say) = flaccida MacGillivray, and raui Rohwer; pulchella (Klug) = albifacies Kirby, dyari Rohwer, ornata MacGillivray, and trosula (Norton); pulchelliformis Rohwer = sambuci Rohwer; trisyllaba (Norton) = zonalis Norton; and varia (Norton) = fascialis Norton, and fascialis var. puella Ross. Macrophya varius var. festana Ross is removed from synonymy with M. varia (Norton) and accorded specific status, and the following species removed from previous synonymy and recognized as valid species: simillima Rohwer from intermedia (Norton); flavolineata (Norton), lineatana Rohwer, and zoe Kirby from pulchella (Klug); and oregona Cresson from pumila Norton. Macrophya dejecta (Norton) is removed from the list of Nearctic species, and is removed from synonymy with M. cinctula (Norton) but synonymized with the Palearctic species M. ligata (Müller). Macrophya annulipes Cresson and M. coquilletti (Rohwer) are considered to belong to an undescribed genus and are excluded from Macrophya; and Allantus cestus Say, and the fossiliferous species Macrophya pervetusta Brues, are considered as unrecognized taxa of Tenthredinidae. Neotypes are designated for Allantus intermedius Norton and A. epinotus Say, and lectotypes designated where necessary. The limits of the genus and subgenera are discussed, and the Palearctic and Nearctic faunas compared through species-groups. Keys to the males and females are given, all species described, and the taxonomic characters used to separate the Nearctic species illustrated in figures taken by electron photography and microphotography.

AbstractA revision of the species in the genus Pityophthorus Eichhoff in North and Central America is presented. The limits of Pityophthorus are expanded to include the species previously placed in Gnatholeptus Blackman. This unit is maintained as a subgenus. One additional subgenus is described, Hypopityophthorus, for P. debilis Wood and P. inops Wood. The genus contains 220 species in North and Central America. The principal subgenus Pityophthorus is divided into 47 species groups. New species are: micans (Mexico), sapineus (Mexico), miniatus (Honduras, Guatemala, and Mexico), pubifrons (Mexico), and acceptus (British Columbia, Wyoming). New synonymy is proposed as follows: P. deletus LeConte (= P. dolus Wood); P. exquisitus (Blackman) n. comb. (= P. inceptis Wood); P. intextus (= P. ornatus Blackman and P. limatus Wood); P. balsameus Blackman (= P. angustus Blackman) and P. indigens Wood (= P. irritans Schedl). Five species are given new status as subspecies: P. tuberculatus Eichhoff as a subsp. of P. pulchellus Eichhoff; P. subopacus Blackman as a subsp. of P. segnis Blackman; P. bellus Blackman as a subsp. of P. confusus Blandford; P. agnatus Blackman as a subsp. of P. confertus Swaine, and P. aurulentus Bright as a subsp. of P. murrayanae Blackman.The monograph includes an historical review, a discussion of diagnostic characters, and a discussion of the general biology of species in the genus. Keys to subgenera, species groups, and species are provided. Each species is described and many are illustrated, and all known bionomic and distributional data are included. Distribution records of many species are mapped.

Bergiantina, a new Agaristinae genus, is described. The genus contains 8 species. Three were previously assigned to Aucula Walker: Metagarista hilzingeri Berg, Euthisanotia magnifica Schaus, and Aucula schausi Jörgensen. Two were previously assigned to Erocha Walker: Heterocampa dolens Druce and Erocha trita Druce. Three new species are described: Bergiantina intermedia, B. parva, and B. familiae. Bergiantina can be distinguished from other Agaristinae by its distinctive forewing pattern with white patches or stripes associated with the postmedial line. Other diagnostic characters include: male genitalia with moderately asymmetric valves, aedoeagus with an apical sclerotized horn-like dorsal projection, and female genitalia with a thin, membranous ductus bursae 3x as long as anterior apophysis. Adults and male and female genitalia are described and illustrated, and a key to species provided. One new synonymy is established and two lectotypes are designated.

We revise the genus Acanthoctenus Keyserling, 1877 recognizing thirteen valid species, of which five are new species and two are re-validated. Further, we find one new synonymy and transfer one species. We describe Acanthoctenus alux sp. nov. from Guatemala, A. chickeringi sp. nov. and A. lamarrei sp. nov. from Panama, A. manauara sp. nov. from Brazil and A. torotoro sp. nov. from Bolivia. We revalidate Acanthoctenus dumicola Simon, 1906 stat. res. from Venezuela, and A. virginea (Kraus, 1955) stat. res., comb. nov. from El Salvador. We transfer Acanthoctenus mammifer to Viracucha mammifer (Mello-Leitão, 1939) comb. nov., from Brazil. Acanthoctenus maculatus Petrunkevitch, 1925 and Gephyroctenus kolosvaryi Caporiacco, 1947 are considered species inquirendae in Acanthocteninae and Ctenidae, respectively, and A. obauratus Simon, 1906 and A. rubrotaeniatus Mello-Leitão, 1947 are considered incertae sedis in Acanthocteninae and Acantheinae, respectively. We also describe for the first time the female of Acanthoctenus spiniger Keyserling, 1877, the type species of the genus. We provide illustrations of male and female diagnostic characters, genitalia, habitus, and measurements to support the genus re-description and further identification of its species. We yield a distributional map of the specimens recorded and the description of the natural history of Acanthoctenus manauara sp. nov.

AbstractThe species of the genus Sepedophilus (Staphylinidae: Tachyporinae) of America north of Mexico are revised. Thirty species are recognized. Thirteen new species are described: wickhami from the northeastern United States and southeastern Canada; brachypterus, frosti, micans, ctenidialis, and kiteleyi from eastern North America; beckeri from the southcentral United States; and hermani, smetanai, stephani, arizonensis, coronadensis, and velox from the southwestern United States. The following species names are placed in synonymy: knoxii LeConte and carissimus Hatch (= littoreus Linnaeus); imbricatus Casey, limuloides Casey, and elongatus Blatchley (= testaceus Fabricius); corticola Casey (= cinctulus Erichson); virginiae Casey (= velocipes Casey); and subtilis Casey (= debilis Casey). The species cinctulus Erichson and bisignatus Horn, formerly considered as synonyms of opicus Say and bipustulatus Fabricius respectively are recognized as valid species. The Palearctic species marshami Stephens is reported for the first time from the Nearctic region. The usage of the generic group names Sepedophilus Gistel, Conurus Stephens, Conosoma Kraatz, and Conosomus Motschulsky is discussed. The North American species are divided into 12 species groups based on an examination of the Nearctic, Neotropical, and Palearctic faunas. The distribution of each species is mapped, and the male and female eighth abdominal sternites and tergites, the male genitalia and other diagnostic characters, are illustrated. A neotype is designated for Tachyporus opicus Say, and lectotypes are designated when necessary for all the North American species of Sepedophilus described by Gravenhorst, Erichson, LeConte, Horn, and Casey. A diagnostic key for all the species except S. heathi Wasmann is given. A brief discussion of the nomenclatural history of the genus, of collecting techniques, and of the major diagnostic characters is included.

Miltochrista Hübner, [1819] is one of largest genera of lichen-moths (family Erebidae, subfamily Arctiinae, tribe Lithosiini) including more than 160 valid species, widely distributed in Oriental and Palearctic Regions. For a long time, the genus was treated in a wide sense. Holloway (2001) treated Miltochrista as a small group of species close to the type species of the genus Noctua rubicunda [Denis & Schiffermüller], 1775 (a junior synonym of Miltochrista miniata (J.R. Forster, 1771)), whereas the majority of other Palaearctic and Oriental Miltochrista-like species was assigned to the genera Lyclene Moore in Horsfield & Moore, [1860] and Barsine Walker, 1854. Kirti & Singh (2016) synonymized Lyclene with Miltochrista and at present the genus is treated in wide sense. Nevertheless, Miltochrista in its modern treatment is a heterogeneous group, the status of Lyclene and some other species-groups with significantly different male and female genital structures is unclear, and the generic/subgeneric structure of Miltochrista sensu lato is under revision by Volynkin & Dubatolov (in prep.).

AbstractThe genus Endeius Coiffait & Sáiz, 1968 (Staphylininae: Staphylinini), distributed from Chile and Argentina through Juan Fernández Is. and Galapagos Is., is revised using characters of external morphology and male and female genitalia. Endeius comprises seven valid species: E. punctipennis (Solier), E. nitidipennis (Solier), E. subpunctipennis Coiffait & Sáiz, E. loensis Coiffait & Sáiz, E. franzi Sáiz, E. lugubris Sáiz and E. ovaliceps Coiffait. Belonuchus multipunctatus (Coiffait), comb. nov., is excluded from Endeius. An identification key to all species of the genus is provided. Monophyly of Endeius, as considered in the present study, is supported by one synapomorphy from the external morphology. Within the genus, the best supported subgroup consists of E. punctipennis (Solier), E. subpunctipennis Coiffait & Sáiz, E. loensis Coiffait & Sáiz and E. ovaliceps Coiffait.
