Abstract Anastrangalia reyi (Heyden, 1889) and Anastrangalia sequensi (Reitter, 1898) are morphologically similar species described in late of XIX century. The recent barcoding revealed that A. reyi is almost identical to another species, Anastrangalia dubia (Scopoli, 1763), by the sequence of nucleotides in cytochrome C oxidase subunit I (COI). Consequently, the taxonomic position of these species is unclear. We have conducted a comprehensive meta-analysis of available data of COI sequences combined with a study of morphological characters of the male genitalia of A. reyi, A. sequensi and A. dubia. Based on 87 sequenced samples we built well-resolved phylogenetic maximum likelihood tree. We found the clades of A. dubia, A. reyi and A. sequensi to be closely related and arranged in the dense cluster. Despite this, numerous cases of introgressive hybridization of A. reyi and A. dubia were identified, indicating an inadequate reproductive barrier between them. The study of morphological features of male genitalia of A. reyi, A. sequensi and A. dubia shows minor differences between them. Based on these facts and the results of the phylogenetic analysis we propose to consider A. reyi and A. sequensi to be subspecies of A. dubia.

In 2017 the second author encountered a rather small Noctuidae species in western Sichuan (China) with unicolorous brown forewings and ochre reniform stigmata. Initially the six males collected resembled the taxa of the genus Cerapteryx Curtis, 1833, but the more gracile body, the finely serrate (and not bipectinated) male antennae and the late flight period indicated the need of further study. Dissection of the male genitalia revealed that the peculiar species belongs to the genus Blepharosis Boursin, 1964. The most recent review with descriptions of new Blepharosis taxa is available from Hreblay, Ronkay & Plante (1998). Comparison of external and genitalia features of the newly found taxon with the known species confirmed that it represents an undescribed species, which is very different externally from all but one of the members of Blepharosis. Regarding the configuration of the male genitalia, the only similar species is Blepharosis anachoretoides (Alphéraky, 1892), displaying only surprisingly small differences between the two species. The large difference between their barcodes (13.5% difference in the COI sequences) indicate however their specific distinctness despite their similar male genitalia structures.

Ba Den is an isolated mountain in southern Vietnam and home to two endemic species of lizards. Herein, we describe another endemic species, a new skink of the genus Scincella Mittleman, 1950, from the area based on morphological data, including hemipenial characters and nucleotide sequences of COI. The following morphological characters diagnose Scincella badenensis sp. nov.: medium size in adults (snout-vent length up to 64.4 mm); toes reach to fingers when limbs adpressed; midbody scale rows 32–36, smooth; paravertebral scales 67–71; dorsal scales not enlarged; ventral scale rows 68–74; supraoculars four; prefrontals in broad contact with one another; loreal scales two; tympanum deeply sunk, without auricular lobules; two enlarged anterior temporal scales; smooth lamellae beneath toe IV 18–20; pair of enlarged precloacal scales; hemipenes short, smooth and forked near the tip with two short lobes and two small terminal papillae; no dorsal pattern in males; and females with black interruptive vertebral line. The new species differs from its congeners by at least 10.4% uncorrected p-distance in COI sequences.

The fossil Prosyntexis species from the Lower Cretaceous Crato Formation of Brazil are revised. The examination of three new specimens of the sepulcid species Prosyntexis gouleti Sharkey, 1990 allows amending its species diagnosis by adding new morphological characters, especially from the wing venation and from the hitherto unknown antenna. A close comparison with Prosyntexis legitima Martins-Neto et al., 2007 demonstrates that this species is a junior synonym of P. gouleti (syn. nov.). The taxonomic position of the genus Prosyntexis within Sepulcidae: Trematothoracinae and of the enigmatic Prosyntexis montsecensis Rasnitsyn and Ansorge, 2000 are discussed on the basis of the new morphological data.

Water mites of the genus Hygrobates are widely distributed in all biogeographic regions except the Antarctic. Palaearctic Hygrobates species with reticulated soft integument generally have been considered as representatives of one common and widely distributed species, Hygrobates fluviatilis Strøm, 1768. Based on partial COI sequences (DNA-barcodes) and statistical analysis of morphological data, we show that these mites belong to six distinct lineages. Two of them are widely distributed in Central Europe: Hygrobates fluviatilis here redescribed based on a neotype designated from the type locality in Norway, and a species new to science, H. arenarius Smit & Pešić. The four remaining lineages represent additional species new to science that appear to have more restricted distributions: H. corsicus Pešić & Smit (Corsica, Sardinia), H. marezaensis Pešić & Dabert (Montenegro, Albania, Croatia), H. turcicus Pešić, Esen & Dabert (Turkey), and H. persicus Pešić & Asadi (Iran, E Turkey). Statistical morphometric analysis reveals that the latter two species cannot be separated on morphological characters and should be considered true cryptic species. We provide data concerning biology and geographical distributions together with a key to all species of the complex.

Two kinds of drug-type Cannabis gained layman’s terms in the 1980s. “Sativa” had origins in South Asia (India), with early historical dissemination to Southeast Asia, Africa, and the Americas. “Indica” had origins in Central Asia (Afghanistan, Pakistan, Turkestan). We have assigned unambiguous taxonomic names to these varieties, after examining morphological characters in 1100 herbarium specimens, and analyzing phytochemical and genetic data from the literature in a meta-analysis. “Sativa” and “Indica” are recognized as C. sativa subsp. indica var. indica and C. sativa subsp. indica var. afghanica, respectively. Their wild-growing relatives are C. sativa subsp. indica var. himalayensis (in South Asia), and C. sativa subsp. indica var. asperrima (in Central Asia). Natural selection initiated divergence, driven by climatic conditions in South and Central Asia. Subsequent domestication drove further phytochemical divergence. South and Central Asian domesticates can be distinguished by tetrahydrocannabinol and cannabidiol content (THC/CBD ratios, ≥7 or <7, respectively), terpenoid profiles (absence or presence of sesquiterpene alcohols), and a suite of morphological characters. The two domesticates have undergone widespread introgressive hybridization in the past 50 years. This has obliterated differences between hybridized “Sativa” and “Indica” currently available. “Strains” alleged to represent “Sativa” and “Indica” are usually based on THC/CBD ratios of plants with undocumented hybrid backgrounds (with so-called “Indicas” often delimited simply on possession of more CBD than “Sativas”). The classification presented here circumscribes and names four taxa of Cannabis that represent critically endangered reservoirs of germplasm from which modern cannabinoid strains originated, and which are in urgent need of conservation.

We used a 227-bp fragment of the mitochondrial gene cytochrome oxidase I (DNA “barcode”) in conjunction with morphological data to study specimens of the Neotropical genus Orthocomotis Dognin, 1906, acquired from natural history collections. We examined over 20 species of Orthocomotis from 17 localities in Colombia, Ecuador, and Peru. The analysis identified 32 haplotypes among the 62 specimens and found no haplotypes shared among species. The molecular study revealed not only the usefulness of short COI sequences in discriminating among Orthocomotis species but also showed distinctness of four clusters which correspond to those based on morphological (genitalia) characters. Moreover, the molecular results suggest the occurrence of rapid speciation in Orthocomotis. We hypothesize that this may be linked to the great biodiversity of potential host plants in Neotropical ecosystems.

The genus Dragmatucha Meyrick is reviewed and 11 species of a total of 13 are described as new. The new species originate from the Democratic Republic of Congo, Ghana, Kenya, and Uganda. Based on morphological characters, especially the color pattern of both wings, the genus is divided into two species-groups: the proaula species-group with five species (D. proaula Meyrick, 1908; D. galbinea Park, sp. nov.; D. kabarolensis Park, sp. nov.; D. saltualis Park, sp. nov. and D. vittatella Park, sp. nov.) and the hispidula species-group with eight species (D. hispidula Park, 2018; D. goniotes Park, sp. nov.; D. cochliana Park, sp. nov.; D. pedalis Park, sp. nov.; D. ghanaensis Park, sp. nov.; D. crinifrutalis Park, sp. nov.; D. dizostera Park, sp. nov. and D. kakumensis Park, sp. nov.). Adults and male genitalia of all new species are illustrated, but female genitalia are provided only for D. ghanaensis Park, sp. nov. and D. kakumensis Park, sp. nov. When fresh material was available, the analysis of COI sequences was undertaken.

An updated checklist of Mozambican marine brachyuran crabs is generated based on an exhaustive revision of the existing literature, together with the additional records provided by the specimens collected throughout the three “MOZAMBIQUE” surveys carried out in Mozambican waters during three consecutive years (2007–2009) by the Instituto Español de Oceanografía, (Spanish Institute of Oceanography, IEO). A total of 269 species, grouped in 15 superfamilies, 26 families and 172 genera are reported in the checklist, and a detailed inventory is produced with the list and remarks about the brachyuran species collected. Thirty-nine crab species belonging to 19 families were identified based on morphological characteristics and/or genetic tools. DNA barcode sequences (16S rRNA and/or COI) were obtained for 37 species, including 16S and COI sequences that are new for 26 and 14 species, respectively. Colour photographs of fresh specimens illustrate the comments about most species, being the first time that the original colour pattern is described for some of them. New records in Mozambican waters are reported for the species Paromolopsis boasi, Mursia aspera, Carcinoplax ischurodous, Tanaoa pustulosus, Euclosiana exquisita, Oxypleurodon difficilis, Naxioides robillardi, Samadinia galathea, Cyrtomaia gaillardi, Paramaja gibba, Pleistacantha ori, Parathranites granosus, Parathranites orientalis, Ovalipes iridescens and Charybdis smithii, and second records for Moloha alcocki, Samadinia pulchra and Charybdis africana. In addition, Raninoides crosnieri, S. galathea and P. ori were collected for the first time after their descriptions. The female of Samadinia galathea is described for the first time, and a potential new species of Mursia is reported. Some records expand the known bathymetric range of certain species and/or their general distribution. New molecular and morphological data suggest the necessity of the revision of P. boasi, R. crosnieri, C. africana and the genera Platymaia and Carcinoplax. The variability and taxonomic validity of some morphological characters in brachyuran systematic is discussed.

AbstractThe taxonomic status of Dendroctonus vitei Wood (Coleoptera: Curculionidae: Scolytinae) and Dendroctonus mexicanus Hopkins is supported by biological and morphological data. However, the differentiation of these species has been extremely difficult because most of the morphological characters have not been well illustrated and some of them are geographically variable. Seminal rod shape has been the only reliable characteristic to identify these species. The main purpose of this study was to look for new morphological characters for the identification of these species as well as to evaluate geographic variation of those previously reported characters in order to produce a comprehensive redescription of D. vitei. A total of 33 morphological characters from antenna, stridulatory apparatus, male and female genitalia, and external morphology were compared between the similar species D. vitei and D. mexicanus, and we identified five novel diagnostic characters and confirmed previously reported characters that differentiate these two species from each other and from other species in the Dendroctonus frontalis Zimmermann complex (sensu stricto). Furthermore, these characters and those of the seminal rod allowed us to re-evaluate some previously reported records for other species to broaden the known distribution of D. vitei.

Two morphologically similar species of the fungicola species group of Bradysia Winnertz, 1867 were studied in China: Bradysia chenjinae Yang, Zhang & Yang, 1993 and Bradysia minorlobus Yang, Shi & Huang sp. n. The morphological species concepts were supported by the DNA barcodes of COI sequences. The genetic distances of 16 Bradysia fungicola group species were analyzed and a neighbor-joining tree was constructed. The morphological characters of both Chinese species were described and illustrated.
