The “Lozopera” species group of the genus Aethes Billberg, 1820 comprises at least 26 described valid species distributed in the Palaearctic region. Most of them share similar external morphology and are identified mainly after their genitalia. The genitalia morphology of both sexes is comparatively complex and the taxa of the group are surrounded by numerous taxonomical problems. A thorough study of the genital morphology, aiming to solve some of the problems, revealed the existence of a microscopic seta on the vesica of the male phallus. SEM and light microscopy observations suggest that it is sensillum chaeticum and probably has a (mechano) receptive function. It is present in some species and absent in others, but always located near the gonopore. In some species a large acantha with similar location was found, instead. Apart from the “Lozopera” species group, such a sensillum was observed in other Aethes spp. and in other genera of the tribe Cochylini as well. Such a structure has never been reported on the vesica of a moth.

The genus Episcepsis Butler, 1877 is widely distributed in the Neotropical region and currently includes 43 valid species many of them described solely based on external morphology. The existence of species complexes makes their identification difficult without examination of genital morphology. Four new species from Brazil, Cuba and Peru are described herein; Episcepsis andina sp. nov., E. diversa sp. nov., E. insularis sp. nov. and E. travassosi sp. nov. Comparisons with other similar species as well as photographs of external morphology and male genitalia are provided.

The Neotropical D. agenor species group of the subgenus Luederwaldtinia Martínez, 1951 is taxonomically reviewed. After examination of specimens in collections, the D. agenor species group will consist of seventeen species, a leap from the former nine species: D. agenor (Harold, 1869), D. amplicollis (Harold, 1869), D. belus (Harold, 1880), D. centralis (Harold, 1869), D. deyrollei (Harold, 1869), D. sagittarius (Harold, 1869) stat. rev., D. tristis (Luederwaldt, 1923), D. triquetrus (Luederwaldt, 1923), D. validipilosus (Luederwaldt, 1931), D. fornicatus (Luederwaldt, 1931) [transferred to D. lucasi species group and to which D. bosqi (Pereira, 1941) is considered to be a new synonym], D. inachoides (Felsche, 1901) [transferred from the group fisus (Selenocopris)], D. simplicicornis (Luederwaldt, 1935) [transferred from the group fisus (Selenocopris)], D. subaeneus (Castelnau, 1840) [transferred from the D. carbonarius species group], D. rafanunezi sp. nov. from Mato Grosso, D. henripittieri sp. nov. from Venezuela and D. enioi sp. nov. from Guatemala and Costa Rica. This review was based on external morphology and characters of the male genitalia (aedeagus and internal sac). Descriptions of new species and redescriptions were made after examining the type-specimens of the already described species. Lectotype designations, species revalidations, redescriptions and new species descriptions are provided.

Annotated List

A subgeneric classification for the 318 currently recognised species of the genus Evylaeus recorded from the Palaearctic Region (in the narrower understanding) is suggested. It includes 29 subgenera all of which are keyed. An annotated list of subgenera contains diagnoses and information about type species, general geographic distribution, and species included. The following 19 new subgenera are described: Aerathalictus subg. n. (type species: Melitta aerata Kirby), Biennilaeus subg. n. (type species: Halictus marginatus Brullé), Crassevylaeus subg. n. (type species: Halictus crassepunctatus Blüthgen), Fratevylaeus subg. n. (type species: Halictus fratellus Pérez), Glauchalictus subg. n. (type species: Halictus problematicus Blüthgen), Laevinodilaeus subg. n. (type species: Halictus laevinodis Morawitz), Limbevylaeus subg. n. (type species: Halictus limbellus Morawitz), Loethalictus subg. n. (type species: Halictus loetus Brullé), Malachevylaeus subg. n. (type species: Melitta malachura Kirby), Minutulaeus subg. n. (type species: Hylaeus minutulus Schenck), Monilevylaeus subg. n. (type species: Halictus immunitus Vachal), Nitidiusculaeus subg. n. (type species: Melitta nitidiuscula Kirby), Nodicornevylaeus subg. n. (type species: Halictus nodicornis Morawitz), Pallidevylaeus subg. n. (type species: Nomioides pallida Radoszkowski), Pauxevylaeus subg. n. (type species: Hylaeus pauxillus Schenck), Tricinctevylaeus subg. n. (type species: Halictus tricinctus Schenck), Truncevylaeus subg. n. (type species: Halictus truncaticollis Morawitz), Virenshalictus subg. n. (type species: Hylaeus virens Erichson), Viridihalictus subg. n. (type species: Halictus viridis Brullé). Hylaeus politus Schenck is fixed as the type species of the subgenus Pyghalictus Warncke 1975. Evylaeus albitarsoides (Blüthgen) is resurrected as a valid species. The following new synonymies are ascertained: Halictus fedtschenkoi Blüthgen 1938 = Lasioglossum andromeda Ebmer 1978, syn. n.; Lasioglossum fratellus betulae Ebmer 1978 = L. nupricola Sakagami 1988, syn. n. The lectotype of Halictus fedtschenkoi Blüthgen is designated. Advantages of a more finely divided and hierarchically deeper classification of large taxa are discussed. A synonymic catalogue of species-group names of the Palaearctic Evylaeus, comprising 679 names, appended.

Western Palaearctic

The genus Dascillus Latreille, 1797 in the Western Palaearctic is reviewed by examination of nearly 1,000 specimens, predominantly from Italy, but also other European and Western Asian countries. The study of external morphology and male genitalia shows high variability in all previously used diagnostic characters, which does not enable unambiguous characterisation of currently recognised species. Therefore, we retain a single valid species in the Western Palaearctic—Dascillus cervinus (Linnaeus, 1758) of which we designate the lectorype, and establish its following new synonymies: Dascillus sicanus Fairmaire, 1861 syn. nov., Atopa elongata Faldermann, 1835 syn. nov. Consequently, the following taxa previously synonymised with Dascillus elongatus (D. elongatus var. obscuricollis Pic, 1908 and D. elongatus var. ruficollis Pic, 1908) and D. sicanus (D. parallelus Dohrn, 1872 and D. aprutianus Depoli, 1936) are now considered as synonyms of D. cervinus as well. First records of D. cervinus for Albania, Bosnia and Herzegovina, Macedonia, Montenegro, and some Italian regions are given.

AbstractMale genitalia of Choristoneura species from the Nearctic Region and Palaearctic Region are described and illustrated. The study revealed that the male genitalia are among the most important body parts that contain valuable morphological characters for species distinction or grouping in this genus. They are potentially useful in the clarification of the taxonomic status of species in closely related species groups, such as the spruce budworm species complex in North America.On the basis of 17 interpretable male genital characters and their corresponding evolutionary states, the phylogeny of the genus Choristoneura is inferred and proposed. Nine species groups are recognized: (1) fumiferana, pinus, biennis, orae, occidentalis, lambertiana, carnana, retiniana, and spaldingiana; (2) diversana, murinana, metasequoiacola, and jezoensis; (3) longicellana; (4) lafauryana; (5) conflictana and fractivittana; (6) hebenstreitella, adumbratana, and luticostana; (7) albaniana and lapponana; (8) rosaceana and parallela; and (9) obsoletana and zapulata.Morphological evidence obtained in the present study suggests that two conifer-feeding species groups of Choristoneura, species group 1 from the Nearctic Region and species group 2 from the Palaearctic Region, are related. They represent the least evolved species groups in the genus. Choristoneura rosaceana, C. parallela, C. obsoletana, and C. zapulata, representing some of the species feeding on deciduous trees, are among the most evolved Choristoneura species.

New Information

Some species belonging to the subgenus Orthocladius s. str. van der Wulp, 1874 known to occur in the West Palaearctic region (in Italy in particular) are reconsidered according to evidence from pupal exuviae. Male genitalia and larval characters are excluded in the present study and will be examined in future research. O. ticinoi Rossaro & Prato, 1991 is restored to the original status. O. marchetti Rossaro & Prato, 1991 is confirmed as a valid species. O. pinderi Rossaro & Prato, 1991 is confirmed to be a junior synonym of O. oblidens (Walker, 1856). O. pedestris Kieffer, 1909 and O. obumbratus Johannsen, 1905 are analysed for their differences. Diagnostic characters used up to now to identify Orthocladius s. str. species at the pupal stage are reconsidered and criticised, and new information about their distribution and a key to pupal exuviae of the known West Palaearctic species are given.

Here we present a synthesis on the current knowledge of sphodrine carabids of the southern Levant (Israel, areas under Palestinian control, Lebanon, Jordan, Egypt east of Suez Channel: Sinai). A key for the identification of genera, subgenera and species is provided. Two new species are described: <em>Taphoxenus</em> (<em>Lychnifugus</em>) <em>ziegleri</em> sp. n. is described from Jordan (Type locality: Madaba), close to <em>T</em>. (<em>L</em>.) <em>meridionalis</em> Casale, 1988 (valid species), but markedly distinct for several characters both in external features and male genitalia. <em>Laemostenus</em> (<em>Laemostenus</em>) <em>sinaiticus</em> sp. n. is described from southern Sinai (Type locality: St. Catharina Monastery). This species belongs to the <em>L. quadricollis</em> species group (in the sense of Casale, 1988), and is close to <em>L. aegyptiacus</em> Schatzmayr, 1936. An updated key for the identification of the species of this group known so far in that area, which includes both epigean and subterranean species, is provided. The diagnostic features of all species newly described are illustrated, and their possible relationships are discussed. Furthermore, the features of male genitalia of <em>Laemostenus</em> (<em>Laemostenus</em>) <em>aegyptiacus</em> Schatzmayr, 1936 and <em>Laemostenus</em> (<em>Laemostenus</em>) <em>libanensis</em> (Piochard de la Brûlerie, 1876) are illustrated for the first time. The latter, known so far from the remains of the holotype specimen, is redescribed from material recently sampled in Lebanon.
