Most species of the Colletes succinctus group sensu Noskiewicz, 1936 are taxonomically uncertain. This study has chosen an integrative approach, including pollen analysis, morphology, male genitalia, morphometry, cuticle sculpture and DNA-barcoding (CO1) to investigate the five species that were reported from Austria. It includes a detailed analysis of the male genitalia and the first description of the C. pannonicus male. A syntype male from the island of Crete was designated as the lectotype of Colletes succinctus brevigena Noskiewicz, 1936 to fix the species identity. New distinguishing characters were found: in females the shape of the dorsal end of the fovea facialis and, in both sexes, the structure of maxillary palpi, as well as the different puncturation on the mesopleura. Unknown structures on sterna and genitalia of the males proved to be reliable morphological characters. An identification key is provided for all studied species. Morphometry of females did not allow a clear distinction of species. CO1 sequencing confirmed previous studies that only C. collaris clearly deviates from the other species, including C. pannonicus that was analysed for the first time. Pollen analysis showed polylectic, as well as oligolectic, pollen-collecting behaviour. The collected pollen of C. pannonicus confirmed the field observations that this species is strictly oligolectic on Tripolium pannonicum. Due to pronounced intraspecific variation, it is assumed that the species of the C. succinctus group are either species in statu nascendi or very young species. Therefore, it remains important to include ecological data in species identification.

Abstract Populations of Atriplex canescens var. gigantea were found in Lamta, Bouficha-Enfidha (central Tunisia), and Medenine (southern Tunisia). Literature data concerning the presence of this species in Tunisia are contradictory but now our data confirm its occurrence in the country. On the other hand, this variety is reported in the present paper for the first time both in Tunisia and in North Africa in general. Morphological characters and ecological data are presented, as well as notes about patterns of infraspecific variability of A. canescens. Nomenclatural notes on infraspecific names in A. canescens, as well as on the closely related species A. garrettii, are provided. The types of the names A. canescens var. laciniata, A. canescens var. macilenta, A. garrettii, Obione occidentalis var. angustifolia, and Pterochiton occidentale, that in earlier publications were erroneously considered to be holotypes, are in fact lectotypes (for most of taxa) under Art. 9.10 of the ICN. Isolectotypes were found at CAS (A. canescens var. laciniata and A. canescens var. macilenta), GH (A. canescens var. macilenta), and YU (Atriplex nuttallii).

Within the scorpion genus Vaejovis C.L. Koch, the “mexicanus” group is composed of species distributed in the mountains of México. This group presents taxonomic problems, because its characterization and the species included in the group have varied through the years. In the present work, we redefine this group based on several morphological characters, and we differentiate it from the other two species groups within the genus: “vorhiesi” and “nit dulus+nigrescens”. Additionally, five new species are described: Vaejovis ceboruco sp. nov., Vaejovis nanchititla sp. nov., Vaejovis santibagnezi sp. nov., Vaejovis talpa sp. nov. and Vaejovis tapalpa sp. nov; the males of three species are described for the first time (V. dugesi, V. nigrofemoratus and V. tesselatus); and the updated diagnosis for all species is included. Keys for the identification of males and females of the 30 species included in this group are given. Lastly, notes on the natural history and distribution of some species are provided, with maps of known distribution for all the species.

A phylogenetic analysis of the polychaete clade Terebelliformia (Terebellida) was undertaken in order to test monophyly of families and subfamilies and to determine their affinities. Parsimony analyses of 41 terebelliform species with outgroup Owenia fusiformis and 46 morphological characters yielded 106–144 most parsimonious trees with length 250, consistency index=0·432, retention index=0·659 and rescaled consistency index=0·285. Monophyly was indicated for Alvinellidae, Ampharetidae, Terebellidae and Trichobranchidae and the terebellid subfamily Polycirrinae. Monophyly of Terebellidae is supported by the presence of a ridge-like tentacular membrane. Monophyly of Polycirrinae is supported by the loss of branchiae, trilobed upper lip, pinnate secondary notochaetae and ventro-lateral pads. Recognition of Polycirrinae renders taxa in the other terebellid subfamilies—Terebellinae and Thelepodinae—paraphyletic. Our results do not support previous classifications that placed Trichobranchidae as a subfamily of Terebellidae; rather it should be considered equal in rank with Alvinellidae, Ampharetidae, Terebellidae and Pectinariidae. The following relationships were obtained: (Trichobranchidae ((Alvinellidae, Ampharetidae) (Pectinariidae, Terebellidae))). This is the first time a Pectinariidae–Terebellidae sister group relationship has been found; it is supported by the synapomorphic presence of ventral glandular shields.

The complexity of the evolutionary history of Senecio is reflected in its conflicted taxonomy. Within this genus, Senecio section Crociseris (Compositae, Senecioneae), a group of perennial herbs distributed in Europe, western and Central Asia, and northwestern Africa, was not fully revised. A worldwide revision of this section recognizing 28 species and eight subspecies is presented here. The main morphological characters revealed as useful for distinguishing between species are the number and shape of supplementary and involucral bracts, synflorescence architecture, indumentum, and the shape and size of leaves and achenes. In this new taxonomic treatment S. provincialis and S. lagascanus have been segregated from S. doronicum, within which three subspecies are recognized (S. doronicum subsp. orientalis is validly published herein). On the other hand, S. ruthenensis from France and S. lusitanicus from Portugal have been synonymized to S. lagascanus, as well as S. ovatifolius, S. pisidicus, and S. tmoleus from Anatolia to S. kolenatianus, S. olympicus, and S. castagneanus respectively, S. bertramii from Lebanon to S. cilicius, and S. delbesianus from Syria to S. racemosus subsp. racemosus. Sixty eight names are lectotypified, the names S. barrelieri, S. pyrenaicus, and S. scopolii are neotypified, and one epitype is designated for the name S. perralderianus. Descriptions and distribution maps are provided for all the species included, as well as an identification key. Nine species are illustrated for the first time.

The species belonging to the subgenus Molopsis Schatzmayr, 1943 of genus Tapinopterus Schaum, 1858 are revised. Thestudy is based on 372 specimens and includes, for each taxon, diagnosis, description (only for the new species), references,new distributional records and illustrations. Morphological characters of the male and female genitalia are widely used todelimit the separate species, the significance of some non-gonapophyseal genital structures of the females for the system-atics of Molopsis is explicitly emphasized. For the first time, the male genitalia of T. molopiformis, T. molopinus, T. wie-demanni, and T. rebellis, including also newly described species, as well as female genitalia of Molopsis are described andillustrated. All available type material is listed and represented by habitus photographs.As a result, 9 monotypic species of Molopsis are recognized. Tapinopterus rebellis (Chaudoir, 1868) and T. rebelliskumanensis (Reitter, 1884), formerly assigned to Molopsis are recognized as outgroup-taxa. The following new speciesare described: T. (Molopsis) aenigmaticus sp.nov. (Asian Turkey, „Armenia“ imprecise locality), T. (Molopsis) chaudoirisp.nov. (Asian Turkey, Bursa Villayet, Uludağ Mt., Sakarya (Adapazari) Villayet, Gökdağ Mt.), T. (Molopsis) oyukluensissp.nov. (Asian Turkey, Konya Villayet, Fasihan Pass), and T. (Molopsis) relegatus sp.nov. (Asian Turkey, Bolu Villayet,Mengen env., Dorukhan Pass). The following nomenclatural acts are also proposed: Tapinopterus (Molopsis) molopinus (Chaudoir, 1868) = Tapinopterus (Molopsis) dipojranus brussanus Straneo, 1984, syn.nov.; Tapinopterus (Molopsis)

Taxonomic notes are presented on the former Ascalaphidae (owlflies), now subfamily Ascalaphinae of the family Myrmeleontidae from Pakistan. An updated checklist of new records is provided that accounts for all known 15 genera and 22 species from Pakistan, excluding the species of the tribe Palparini. Geographical distribution maps and an updated identification key to all known genera and species from Pakistan are also given. We synonymized two monotypic genera, Horischema Mészáros & Ábrahám, 2003 and Perissoschema Mészáros & Ábrahám, 2003 both as junior synonyms of Ogcogaster Westwood, 1847 based on very similar male genitalia and external morphological characters. Moreover, Perissoschema evae Mészáros & Ábrahám, 2003 is treated as a junior synonym of Ogcogaster segmentator Westwood, 1847. We recorded three genera for the first time from Pakistan, i.e., Acheron Lefèbvre, 1842, Glyptobasis McLachlan, 1873, and Suphalomitus van der Weele, 1909. To more completely resolve the generic or specific status of those poorly known species from Pakistan, broader sampling throughout the country is needed.

Tipulomorpha (crane flies) comprise one of the largest subgroups of Diptera, but its phylogeny at different levels has been poorly explored. This study presents the most comprehensive cladistic analysis of the group ever made, with emphasis on the genera and subgenera of the subfamily Limnophilinae (Limoniidae), assumed to include some of the earliest lineages of Tipulomorpha sensu stricto and therefore important for the understanding of the early patterns in the evolution of the crane flies. Eighty-eight characters of the male imago were scored for 104 exemplar species. The most parsimonious trees were searched using implied weighting, in the framework of a sensitivity analysis with different values of k (2 to 6). The dataset based on the characters of adult male morphology showed high levels of homoplasy and yielded very incongruent and unstable phylogenetic results, which are very sensitive to changes in analytical parameters. In the preferred and most parsimonious phylogenetic hypothesis, the Pediciidae is the sister-group of all other Tipulomorpha sensu stricto. The results indicate the paraphyly of the Limoniidae with respect to the Cylindrotomidae and Tipulidae, which are considered sister-groups. The Limoniidae subfamilies Limnophilinae, Limoniinae and Chioneinae are considered non-monophyletic. The study allowed a reconstruction of the possible ground plan condition of selected features of the adult male morphology of crane flies. The genera/subgenera Epiphragma (Epiphragma), Acantholimnophila, Shannonomyia, Limnophila (Arctolimnophila), Eloeophila, Conosia, Polymera, Polymera (Polymerodes), Prionolabis, Eutonia, Phylidorea (Phylidorea), Metalimnophila, Gynoplistia (Cerozodia), Gynoplistia (Dirhipis), Nothophila, Pseudolimnophila (Pseudolimnophila), Pilaria and Ulomorpha are considered monophyletic, but in general are defined by combinations of very homoplastic character states. Two Temperate Gondwanan clades, (Tonnoirella + (Edwardsomyia + (Tinemyia + (Rhamphophila + (Nothophila))))) and ((Notholimnophila + Bergrothomyia) + (Mesolimnophila + (Chilelimnophila + Ctenolimnophila))) are recovered. The genera Limnophila, Neolimnomyia, Gynoplistia (sensu lato) and Hexatoma (sensu lato) are considered non-monophyletic. The systematic position and some morphological characters of ‘problematic’ taxa, such as Dactylolabis, Elephantomyia, Helius and Atarba are discussed on the light of the proposed phylogeny and the analysis of the characters. Character states are richly illustrated. A detailed study of the morphology of the male genitalia is made, and several genera and species have the morphology of the male genitalia illustrated for the first time.
