In this paper we improve the morphological description of the tree cricket Neoxabea brevipes Rehn, 1913 and a new occurrence record for the species at the São Francisco de Paula National Forest Conservation Unit, State of Rio Grande do Sul, southern Brazil. Morphological characterization is provided together with illustrations emphasizing the most significant diagnostic features, such as the metanotal gland, abdominal specializations and phallic sclerites. The calling song was field recorded, comprising a continuous trill with dominant frequency of 3.6 kHz (19.7°C). The karyotype was described for the first time to Neoxabea Kirby, 1906, including diploid number of 2n=26, with two sexual chromosomes.

AbstractTwo species of the genus Thesium (T. ebracteatum and T. linophyllon) are constantly recognized as members of the flora of Lithuania. However, the study on plants currently occurring in Lithuania and usually identified as T. linophyllon revealed that in fact they belong to T. ramosum. The analysis of all available data on the occurrence of T. linophyllon in Lithuania indicated that this species has never been recorded. The report on the occurrence of T. linophyllon, published at the end of the 18th century, was based on misidentified T. ebracteatum. Thus, T. linophyllon should be excluded from the list of vascular plants of Lithuania. Occurrence of T. ramosum was reported for the first time in the country. Currently, one population of this species with two subpopulations are known in the environs of Varnikai village (Trakai distr., Trakai Historical National Park). Morphological description of T. ramosum and diagnostic features of this species were provided. The structure and habitat conditions of two subpopulations were investigated in 2017. The present population of this species was revealed to consist of 52 individuals. Occurrence of young individuals in one subpopulation indicates generative reproduction of T. ramosum. Negative relationship between the number of T. ramosum individuals and the coverage of Poaceae species, and positive relationship between the coverage of Fabaceae species were revealed. Localities of T. ramosum in Lithuania are far from the area of its native distribution, and this species is ascribed to the group of established alien species. Further spread and invasion of the species is not expected.

Abstract Background The Scolopacidae family (Suborder Scolopaci, Charadriiformes) is composed of sandpipers and snipes; these birds are long-distance migrants that show great diversity in their behavior and habitat use. Cytogenetic studies in the Scolopacidae family show the highest diploid numbers for order Charadriiformes. This work analyzes for the first time the karyotype of Actitis macularius by classic cytogenetics and chromosome painting. Results The species has a diploid number of 92, composed mostly of telocentric pairs. This high 2n is greater than the proposed 80 for the avian ancestral putative karyotype (a common feature among Scolopaci), suggesting that fission rearrangements have formed smaller macrochromosomes and microchromosomes. Fluorescence in situ hybridization using Burhinus oedicnemus whole chromosome probes confirmed the fissions in pairs 1, 2, 3, 4 and 6 of macrochromosomes. Conclusion Comparative analysis with other species of Charadriiformes studied by chromosome painting together with the molecular phylogenies for the order allowed us to raise hypotheses about the chromosomal evolution in suborder Scolopaci. From this, we can establish a clear idea of how chromosomal evolution occurred in this suborder.

Gymnocolea borealis is reported for the first time for Asia from Russia based on the morphological and subsequent molecular-genetic comparison of rbcL cpDNA sequence of the specimen from the Gydansky Peninsula, West Siberian Arctic. An extended morphological description, generalizing the species characters throughout its range, and data on its variation, differentiation and ecology, and photomicrographs are provided. The occurrence of G. borealis growing as separate shoots among dense mire vegetation makes it easy to overlook. Presently known isolated records of G. borealis support its disjunctive circumpolar distribution.

The Jaú National Park, located in the Amazon, is the largest National Park of Brazil and still its insect fauna is barely known. Herein we describe two new species of Psychodinae, Alepia iy sp. nov. and Parasetomima timmirima sp. nov., and report 19 other species of Psychodidae, subfamilies Phlebotominae, Psychodinae and Trichomyiinae collected from this Conservation Unit. Micrommatos Quate & Brown, represented by M. stephaniae Quate & Brown, and Platyplastinx culmosus Quate & Brown are recorded for the first time for Brazil. Among the collected phlebotomine sand fly species, three species have previously been implicated in transmission of Leishmania: Nyssomyia anduzei (Rozeboom), Psychodopygus ayrozai (Barretto & Coutinho) and Trichophoromyia ubiquitalis (Mangabeira).

The Neotropical tribe Sphaenorhynchini is composed of 15 recognized species commonly named as “lime treefrogs”. Gabohyla pauloalvini occurs in Atlantic Forest lowlands through the states of Bahia and Espírito Santo, Brazil. Based on field observation, literature review, and evaluation of audio files, we conclude that previous bioacoustic descriptions were erroneously assigned to G. pauloalvini. Here, we describe for the first time the advertisement call of G. pauloalvini from two disjunct populations. In addition, we provide new distribution records and an updated map for this species. The advertisement call of G. pauloalvini is composed of 1–5 closely spaced notes, with duration of 0.016–1.976 s, inter-note intervals of 0.340–1.25 s, and an average dominant frequency (= fundamental frequency) of 4966.0 Hz. Harmonics are visible in the spectrogram. Three new populations of G. pauloalvini have been recorded and extended the distribution by 60 km south. Nevertheless, G. pauloalvini is still known only from few localities. We highlight the importance of depositing audio recordings and specimens in scientific collections to promote systematics and natural history studies.

Discovery of a new population of Rhithrogena delphinensis Sowa & Degrange, 1987, in the Arves Massif, and additions to the morphological description of the larva (Ephemeroptera, Heptageniidae). Rhithrogena delphinensis, described originally on the basis of four larvae from the Western Alps, south of the Arves Massif and from the northern flank of the Ecrins Massif, had not been captured again since 1986. Here, we report the discovery of a new population from river Arvan, whose drainage basin is located between the Grandes Rousses Massif and the northern flank of the Arves Massif. This newly discovered population seems abundant in numbers, and reveals the particular ecological requirements of the species as well as its dependence on glacier fed or nival streams. The morphological characteristics of the larvae are described in detail, and illustrated by photographs. The variability of some of the proposed identification criteria is discussed, and a key to the identification of the Rhithrogena species from the alpestris group of the Western Alps, to which R. delphinensis belongs, is provided. Finally, a portion of 658 base pairs of the COI gene of R. delphinensis is sequenced for the first time and compared to already existing data on the alpestris group in the Western Alps.

This study presents chromosomal data of Megalonema platanum from rio Tibagi, Paraná, Brazil and from rio Paraná, Argentina. The diploid number was equal 54 with karyotype composition of 24m+16sm+2st+12a in both populations. The AgNOR sites were detected in the terminal position of a submetacentric pair of the two analyzed populations, coinciding with secondary constrictions on the short arm of pair 15. CMA3 and FISH with 18S rDNA probe displayed fluorescent signals that correspond to the AgNOR sites and secondary constriction. The presence of a small acrocentric supernumerary chromosome can be observed in M. platanum from rio Tibagi, with centromeric heterochromatin. Others heterochromatic blocks were evidenced in the terminal position of some chromosome and one metacentric large chromosome pair, probably the first pair, showed an interstitial heterochromatin. In the population of the rio Paraná were still observed heterochromatic blocks in both ends in some chromosomes. This work brings for the first time cytogenetic date of M. platanum, which is a very rare species in the rio Paraná basin and may be endangered.
