Isophya kraussii Brunner von Wattenwyl, 1878, one of the widest spread bush–crickets within this genus, is confirmed to be present east of the Carpathian Mountains. Based on acoustic analysis and morphological characters, the populations from NE Romania are considered to belong to a different subspecies, I. kraussii moldavica ssp. n. A map with distribution of both subspecies is presented.

Abstract Prinias (Cisticolidae: Prinia) are resident warblers of open areas across Africa and Asia and include many polytypic species whose species limits have not been seriously reevaluated recently. Based on an integrative taxonomic analysis of morphology, song, and mitochondrial DNA (mtDNA), we suggest that 2 species should be recognized in the Graceful Prinia (Prinia gracilis) complex. In addition, our morphological analyses show the existence of a well-marked undescribed form in southeastern Somalia, which we name herein as a new subspecies. Prinia gracilis is a small, drab, long-tailed species with streaking above and plain pale underparts that has been suggested to fall into 2 groups: the southwestern nominate group (from Egypt to Oman) and the northeastern lepida group (from Turkey through India). However, the characters presented to justify this grouping are variable and show a mosaic pattern, and whether genetic and vocal differences exist is unknown. We found consistent between-group song differences, with the nominate group giving consistently longer inter-phrase intervals, whereas the members of the lepida group sing an essentially continuous reel. An mtDNA tree suggests a deep split between the nominate and lepida groups, with a coalescence time between these clades of ~ 2.2 million years ago. Vocal and mtDNA analyses provided evidence that the northeastern Arabian Peninsula taxon carpenteri belongs to the lepida group. We found that, of all the morphological characters proposed, only proportions and tail barring and spotting relatively consistently distinguish the 2 groups. However, these characters strongly suggest that the eastern Arabian Peninsula is populated by taxa of both the gracilis and lepida groups, in different areas, but we lack genetic and bioacoustic data to corroborate this. Although further study is needed in potential contact zones, we suggest that 2 species should be recognized in the P. gracilis complex, and we propose the retention of the English name Graceful Prinia for P. gracilis sensu stricto, while we suggest that P. lepida be known as Delicate Prinia.

AbstractGenus-group taxon Rhombodineutus Ochs, 1926 is related to Paracyclous Ochs (Indonesia) and Callistodineutus Ochs (Melanesia), classified under Dineutus MacLeay. It occurs in New Guinea and New Britain Island, inhabiting streams and rivers primarily at low and medium altitudes where the species may occur abundantly. Most species live in the forests and have a fairly restricted range, while D. pectoralis Régimbart has passed a niche shift and adapted to exposed and exploited land and spread widely, splitting into a considerable number of races, some of which were found at an elevation of 1500-2000 m. The morphological characters are reviewed and their differentiation examined as a background for the classification of the taxon and a revision of its species which have been placed in three groups, containing 8 species and 11 subspecies. One new species and four new subspecies are described. Keys are provided to the various groups of taxa.

Comprehensive Account

Since the publication of the comprehensive account of the genus Nicotiana by Goodspeed and his collaborators (1954), extensive collecting by the author has revealed the existence of a number of undescribed species and has resulted in the compilation of data which allow a better understanding of specific relationships between those previously known. In this paper the morphological characters by which species can be recognized are discussed, and five new species and two new subspecies are described. Two of the new species proved to have 23 pairs of chromosomes, thus filling a gap in the series of from 16 to 24 pairs which, with the exception of 17 pairs, has now been recorded for the Australian taxa. Notes on the relationships, the more important morphological features, and the geographical distribution are provided for all previously recognized species.

AbstractSome insect herbivores can regulate their nourishment intake by different feeding behaviour. This mechanism allows them to persist with utilising different food resources according to the composition of the vegetation within their habitats. Using a two-choice experiment, we analysed foraging behaviour in females of the tree-dwelling bush-cricket Barbitistes constrictus (Orthoptera), which originated from two different forest habitats, spruce and beech forest. We found that individuals from the spruce forest mainly foraged on needle tips, and thus they nibbled more needles per day than individuals from the beech forest (medians 106.0 vs. 42.5; p < 0.0001). However, when the contents of droppings were dissected, the volume of consumed spruce was similar in both groups of bush-crickets (median > 90%), which is explained by the different feeding techniques of bush-crickets from different habitats. We propose possible scenarios for bush-cricket feeding adaptations to the deleterious effects of the host plant chemical compounds serving as a plant defence against herbivores.

Euphorbia otjipembana was hitherto only known from the type locality within the Kaokoveld Centre of Endemism, northwestern Namibia. Subsequently several additional populations were discovered, allowing for an amplified description of the species and the recognition of two subspecies. Euphorbia otjipembana subsp. okakoraensis, here described as a new subspecies, is only known from a small area within the Kaokoveld Centre. Diagnostic characters for subsp. okakoraensis include a shrubby habit and medium (up to 1 m) height, 5–7-angled, scarcely constricted branches with two pairs of spines per node and single cymes comprising of three horizontally arranged cyathia. A key as well as a comparative table with diagnostic morphological characters to distinguish between the two subspecies of E. otjipembana is provided.

Three New Species

Species of the genus Tephritis usually have the wing pattern with dark rays on veins R4+5 and M connected to the preapical dark spot or to each other (often called the “apical fork). Some species, however, have a solid apical crossband (Korneyev, 2013), whereas others have an isolated pair of apical spots. Specimens with the latter morphological character occasionally occur in many species with typical wing patterns, but in this article we focus on the species that normally have it. They occur mostly in the Palaearctic Region, except T. candidipennis Foote, 1960 from North America. A total of twenty species are recognized in this complex, including three new species and two new subspecies: Tephritis arsenii S. Korneyev, 2015, T. bardanae (Schrank 1803), T. conyzifoliae Merz 1992, T. crepidis Hendel 1927, T. dilacerata (Loew 1846), T. dilacerata kaszabi new subspecies, T. formosa (Loew 1844), T. ghissarica new species, T. hendeliana Hering 1944, T. hyoscyami (Linnaeus 1758), T. kyrghyzica new species, T. kogardtauica Hering 1944, T. kovalevi Korneyev & Kameneva 1990, T. kovalevi kumana new subspecies; T. postica (Loew 1844), T. stictica Loew 1862, T. theryi Séguy 1930, T. tridentata S. Korneyev & Mohamadzade-Namin 2013, T. truncata (Loew 1844), T. valida (Loew 1862), T. youngiana new species, and T. zernyi Hendel 1927. Most of the species are keyed, redescribed and illustrated based on extensive material from the Palaearctic Region. Lectotypes of T. dilacerata, T. formosa, T. hendeliana, T. truncata, T. valida, T. posis, T. heiseri, T. procera and a neotype for T. postica are designated. Known host plants of this complex belong to the tribes Anthemideae, Cardueae, Cichorieae, Inuleae, and Senecioneae (Asteraceae); preliminary comparison of the morphological characters (other than the wing pattern) with the distribution among host plants shows that the flies apparently do not form a monophyletic group, belonging to several different lineages, which also include other species with the typical “forked wing pattern. New distribution records and host plants are reported.        The following synonymies are established: Musca hyoscyami Linnaeus 1758 = Tephritis heiseri Frauenfeld 1865 new synonym; Trypeta postica Loew 1844 = Tephritis posis Hering 1939 new synonym.

Morphometric Evaluation

Due to some biological features, species belonging to genus Dorcadion Dalman, 1817 (Coleoptera: Cerambycidae) can be easily divided into isolated populations. This can be considered as an important factor of speciation process and allows the observation of various effects of biological evolution of taxa. These effects can be measured on morphological characters with some different approaches such as geometric morphometrics. This study aims to determine pronotum and elytra shape differences of the samples of three isolated localities of Turkey (Akyurt, Bala, and Beynam) detected in Ankara, and to contribute to taxonomic and evolutionary knowledge of Dorcadion micans Thomson (1867) by evaluating the analysis of outcomes. As a result, significant differences between populations were detected both in pronotum and elytra. Besides, common variations were observed in some morphological characters of the Bala and Beynam populations, unlike Akyurt population. Accordingly, the distinguishing characters are discussed, and the following new subspecies is described: Dorcadion micans majoripunctum ssp. nov. from Ankara province in Northern part of Central Anatolia.

AbstractCompetition is a basic type of interaction between species. Because complete competitors cannot exist in one habitat, closely related species must show at least slight differences in their biology or ecology. In the present study, we analyzed the habitat use of the two closely related bush-cricket species Tettigonia caudata and T. viridissima which often occur syntopically. The meso- and microhabitat use of males was compared in an agricultural landscape in NE Germany. Males of both species were found to use similar mesohabitats and to prefer dense and high vegetation. Microhabitats differed significantly in two aspects: Microhabitats of T. caudata had a higher proportion of herbs, while T. viridissima used higher song posts. These differences in microhabitats might explain the co-occurrence of the bush-crickets in open habitats. However, variation between the two species might also take place during other life-cycle stages such as during egg development.
