Contrary to the subtle differences of habitus found between many species of Timarcha their internal sacs of male genitalia have shown a remarkable variation. Thirty-two Palaearctic taxa, mostly from the Iberian Peninsula, have been analyzed for this trait, which can be used for species diagnosis and also for establishing species groups of close relatedness in agreement mainly with genetic analyses. According with this trait, new synonymies and taxonomical changes are proposed: T. intermedia carmelenae Petitpierre, 2013 stat. nov., T. intermedia kiesenwetteri Kraatz, 1879 stat. nov., T. intermedia lugens Rosenhauer, 1856 stat. nov.; T. sinuatocollis monserratensis Bechyné, 1962 comb. nov.; T. piochardi Fairmaire, 1874 stat. nov.; T. tortosensis Bechyné, 1948 stat. nov.; T. perezii Fairmaire, 1884 syn. nov. and T. asturiensis Kraatz, 1879 syn. nov. = T. geniculata Germar, 1824. Furthermore, the endophalli of T. hummeli, T. carmelenae, T. kiesenwetteri, T. lugens, T. tenebricosa, T. parvicollis, T. insparsa, T. marginicollis, T. balearica, T. strangulata spp., T. calceata, T. scabripennis, T. espanoli, T. monticola, T. cyanescens, T. interstitialis, T. aurichalcea, T. oblongula, T. hispanica and T. granadensis are illustrated. One new species, T. aitanae sp. nov. is described.

AbstractThe systematics of Acalymma sensu stricto of North America including Mexico are revised. Acalymma sensu stricto is defined and distinguished from the other species groups of Acalymma. Sixteen species are discussed including four new species: A. blomorum, A. palomarense, A. invenustum, and A. luridifrons all from Mexico. Three new subspecies of A. blandulum (LeConte) are described: blandulum (LeConte) new status, nigriventre, and yucatanense. Acalymma coruscum costaricense Bechyné is placed as a synonym of A. innubum (Fabricius). Keys are presented to all species and subspecies. Habitus and male genitalia drawings are given for all species and distribution maps are given where appropriate.

DNA barcoding has been recently promoted as a method for both assigning specimens to known species and for discovering new and cryptic species. Here we test both the potential and the limitations of DNA barcodes by analysing a group of well-studied organisms—the primates. Our results show that DNA barcodes provide enough information to efficiently identify and delineate primate species, but that they cannot reliably uncover many of the deeper phylogenetic relationships. Our conclusion is that these short DNA sequences do not contain enough information to build reliable molecular phylogenies or define new species, but that they can provide efficient sequence tags for assigning unknown specimens to known species. As such, DNA barcoding provides enormous potential for use in global biodiversity studies.Key words: DNA barcoding, species identification, primate, biodiversity.

Dichagyris is a diverse genus with a Holarctic distribution. Only a few taxa of the subgenus Albocosta Fibiger & Lafontaine, 1997 occur in the northwesternmost part of the Oriental region. The genus is most diverse in Turkey, Iran and the Central Asiatic high mountains. However, there is a distinct Sino-Tibetan group of species, possibly representing an undescribed subgenus. However, this idea is provisional and awaits revision of the genus. For present purposes, we assign these species to the subgenus Dichagyris. They share the following putative synapomorphies: black, dark brown or dark greyish forewing ground colour (with one exception), with obscure, reduced wing pattern and a broad-based, short, conical harpe in the male genitalia. Species of this group can be subdivided to two species-groups. In the astigmata-group which was mentioned for the first time by Hreblay et al. (1998) but without description or diagnosis from the minuta-group, the vesica is elongate and tubular (males), the appendix bursae and corpus bursae are long, sack–like, almost equal in size (females). In the minuta-group, the vesica is more ample than in the astigmata-group, and coiled, and the appendix bursae is globular and much shorter than the corpus bursae. The astigmata-group includes Dichagyris astigmata (Hampson, 1906), D. gansuensis Hreblay & Ronkay, 1998, D. geochroides (Boursin, 1948) and D. vargazoli (Gyulai & Ronkay, 2001). The minuta-group comprises D. minuta Hreblay & Plante, 1998 and D. kormos Gyulai & Ronkay, 2001. During a research expedition in Sichuan in 2019, the existence of a third species in the minuta-group was recognized, which is described here. In addition, the female and its genitalia of D. gansuensis, which was described by Hreblay & Ronkay (1998) based on a single male, are illustrated here for the first time.

Members of the Monoctonina subtribe have long been neglected in applied studies of the subfamily Aphidiinae, due to their low economic importance, as they do not parasitize pests of cultivated plants. Consequently, data about this group are scarce, including its taxonomy and phylogeny. In the present study, we explore inter- and intraspecific genetic variation of Monoctonina species, including genera Monoctonus Haliday 1833, Monoctonia Starý 1962, Falciconus Mackauer 1959 and Harkeria Cameron 1900. We employ two molecular markers, the barcode region of the mitochondrial cytochrome c oxidase subunit I (COI) and the D2 region of the 28S nuclear gene (28S rDNA), to analyze genetic structuring and phylogeny of all available Monoctonina species, and combine them with morphological data for an integrative approach. We report one new species, and three potentially new species which can be formally described when further specimens are available. Analysis of phylogenetic relationships within the subtribe shows a basal position for the genera Falciconus and Monoctonia, and the close relatedness of Harkeria and Monoctonus.

Two new species of the genus Agrisius Walker, 1855, A. orhanti Volynkin, Dubatolov & Kishida, sp. n. and A. leloii Volynkin, Dubatolov & Kishida, sp. n. are described from South Laos and Vietnam respectively. A. orhanti sp. n. belongs to the A. japonicus Leech, 1889 species-group. Whereas, the male genitalia structure of A. leloii sp. n. is intermediate between those of the A. japonicus and the A. guttivitta Walker, 1855 species-groups, therefore, it is assigned to a separated species-group (the A. leloii species-group). Agrisius dubatolovi Orhant, 2012 is downgraded as a subspecies of A. japonicus: Agrisius japonicus dubatolovi Orhant, 2012, stat. nov. Female genitalia of species of the A. japonicus and most of the A. guttivitta species-groups are illustrated for the first time.

The Iberian Peninsula is a repository for biodiversity, presenting high levels of endemism in both plants and animals. In this peninsular region, brook lampreys confined to small, isolated river basins evolved in allopatry giving rise to evolutionary lineages, as revealed by mitochondrial DNA markers. For a better understanding of the taxonomic status and relationships of Iberian populations of the genus Lampetra, we combined previous data from genetics and morphological analysis (assessed here), and describe three new species of the lamprey genus Lampetra Bonnaterre, 1788 in Portugal. In this region L. planeri actually represent a complex of cryptic species, each having smaller geographic ranges than L. planeri, and consequently, greater vulnerability to extinction. The description of Lampetra alavariensis sp. nov. is based on 36 specimens collected on Ribeira de Mangas, a tributary of river Esmoriz, in Northern Portugal. Lampetra auremensis sp. nov. is described on the basis of 31 specimens collected on Ribeira do Olival, a small tributary of river Nabão (Tagus basin). Finally, Lampetra lusitanica sp. nov. is described based on 38 specimens from Ribeira da Marateca, Sado river basin, the southernmost distribution of the genus Lampetra. The recognition of these new species will contribute to the conservation of these already imperilled taxa and will help prevent the extinction of three important evolutionary lineages.
