Melanophryniscus orejasmirandai is a species of toad known only from two localities in southern Uruguay. This toad isthe southernmost suggested taxon of the M. tumifrons group, whose species are characterized by a glandular frontal swell-ing on the snout. The study of the type series of M. orejasmirandai and of M. pachyrhynus, along with observations madeon many specimens of both species suggested a close relationship between them. The analysis of the variation of snout-vent length, coloration pattern, relative size of the frontal swelling, and presence/absence of the metatarsal gland showedthat characters previously used to separate both species resulted of no diagnostic value. Further comparison of the externalmorphology, osteological characters, and partial sequences of the cytochrome b gene indicated that M. orejasmirandai isa junior synonym of M. pachyrhynus. Melanophryniscus pachyrhynus is characterized by a reticulated orange ventral pat-tern which is shared only with M. peritus, from which it differs by its smaller size. The ornamentation of the nasal bonesunderlying the frontal swelling in M. pachyrhynus seems to be characteristic of the M. tumifrons group. An updated distribution map of M. pachyrhynus and some new localities are also provided.

The distribution of Sonchus palustris in Slovakia was studied using herbarium specimens and literary sources. The herbarium studies, supplemented with targeted field search in the years 2015–2018, revealed 61 new localities and confirmed many other older locations. The species has been recorded in 19 phytogeographical districts and sub-districts of Slovakia. Most of the records are concentrated in the Podunajská nížina lowland in SW Slovakia and in the Ipel'sko-rimavská brázda region in southern Slovakia. Our results showed that the species is relatively common in different types of wetlands and its re-evaluation in the recent version of the Slovak red list is not needed. Chromosome number data for two new populations in eastern Slovakia (both 2n = 18) were counted. The distribution map is given.

Paralactaga williamsi, a five-toed jerboa, is known to occur in Anatolian Turkey, northern Lebanon, Armenia, Azerbaijan and western Iran. Here, we report the first record of this species in Kopet-Dag Mountains, northeastern Iran. Species identification was based on external morphology, skull and molar teeth morphology and morphometrics studies, as well as molecular an­al­yses. Brief notes on the ecology of the species are also provided. This new record expands the distribution of P. williamsi in Iran about 850 km eastward, however further sampling will be needed for a better judgment on the taxonomic status of this species in eastern Iran and to determine the patterns of its distribution. Since the specimen did not group with other P. williamsi in the cytochrome b analysis, we provisionally classify the specimens as P. cf. williamsi.

Brasilocaenis atawallpa was recently described based on male imago from Colombian Amazon. The original description does not contain a designation of type specimens or locality, and it just states that the type series was studied in order to perform the cladistic analysis. In this context, we herein designate the lectotype and paralectotypes of B. atawallpa and describe its nymphal stage. The nymphs were associated to B. atawallpa by the male genitalia extracted from mature nymphs. The nymphal stage of B. atawallpa can be differentiated from others known nymphs of the genus by absence of pointed microspines on opercular gill, fore coxa without projection, middle coxa with well-developed and semicircular projection, hind coxa with finger-like projection, fore and middle tarsal claws without denticles and hind margin of the ninth sternite almost straight.

Species of the genus Oligoryzomys are commonly found accross Latin America, and several of them play important rolesas natural reservoirs of Hantaviruses. Here we demonstrate that O. utiaritensis, the natural reservoir of hantavirus Castelodos Sonhos in northwestwern Brazil and previously considered a junior synonym of O. nigripes or O. eliurus, is a validspecies. Morphology, morphometry, karyotyping, and phylogenetic reconstructions based on nuclear (intron 7 of the beta-fibrinogen gene) and mitochondrial (cytochrome b) DNA show that O. utiaritensis differs from O. nigripes and from otherforms of the genus, including the recently described taxon O. moojeni. Oligoryzomys utiaritensis differs in external (whit-ish ventral pelage and tail weakly bicolored) and cranial (incisive foramina never extending posteriorly the alveolus lineof M1) characters from sympatric species. It has the highest diploid number (2n=72) within Oligoryzomys, and is charac-terized by three putative synapomorphies in cytochrome b, and one in intron 7 of beta fibrinogen. We also point to theassignment of Oligoryzomys eliurus as a junior synonym of O. nigripes. Finally, we present phylogenetic analyses of in-trageneric relationships showing that O. utiaritensis is a member of a clade containing Amazonian and Cerrado taxa, including O. moojeni, O. rupestris, and O. delicatus.

Three New Species

An inventory of Phlebotomine sandflies was carried out in the Ankarana tsingy located in far northern Madagascar. A total of 723 sandflies were used for morphological, morphometric, and molecular studies (sequencing of partial cytochrome B (mtDNA) and partial 28S (rDNA)). Nine species were identified: Phlebotomus fertei, Sergentomyia anka, Se. sclerosiphon, Se. goodmani, two species of the genus Grassomyia, as well as three new species described herein: Se. volfi n. sp., Se. kaltenbachi n. sp., and Se. ozbeli n. sp. The recognition of these new species is strongly supported by molecular analyses. The first two of the new species could not be classified into any existing subgenus, therefore we proposed two new subgenera (Ranavalonomyia subg. nov., and Riouxomyia subg. nov.), with combinations as: Sergentomyia (Ranavalonomyia) volfi and Sergentomyia (Riouxomyia) kaltenbachi. Our study reveals important molecular variability in Se. anka, with the recognition of a population whose taxonomic status remains below that of species. Our research confirms the need to further study the specific diversity of Malagasy sandflies, which until the start of this millennium remained mostly unknown.

A molecular phylogeny of the genus Echinops (Asteraceae, Cardueae) based on plastid and nuclear markers is presented. The study focuses on the Iranian representatives of the genus, which constitute a larger part of Echinops. The Bayesian cpDNA tree resulted in a large polytomy. However, the Bayesian ITS tree displayed a well-resolved topology more compatible with the taxonomic treatment generally accepted in Echinops. An ITS network illustrates a close relationship of haplotypes. Mapping diagnostic morphological characters onto the ITS tree revealed a high level of homoplasy among the studied taxa. Except for the life cycle, all other morphological characters evolved many times among the clades and most of them appeared to be of low taxonomical value. Based on the nucleotide polymorphism and haplotypes, the taxonomic status of some taxa was evaluated. The independent status of E. sect. Phaeochaete was confirmed by molecular analyses and morphological characters. The paraphyletic nature of E. sect. Echinops was confirmed. As for the molecular dating, our results suggest that the genus evolved in the early Miocene but the main speciation events took place in the Pliocene-Pleistocene. The biogeographic results do not support any specific ancestral area for Echinops, yet the model states that its current diversity originated in the Irano-Turanian Region and the Eastern Mediterranean region. Some taxonomic changes are suggested, in the synonymy and placement of some taxa.

In Mexico, the newportiine scolopocryptopid genus Newportia Gervais, 1847, comprises 10 species: N. mexicana (Saussure, 1858); N. azteca Humbert & Saussure, 1869; N. stolli (Pocock, 1896); N. spinipes Pocock, 1896; N. oreina Chamberlin, 1915; N. sabina and pelaezi, both by Chamberlin, 1942; N. atoyaca and morela, both by Chamberlin, 1943, and N. troglobia, n. sp. The last occurs in caves in Tamaulipas and appears to be an obligate troglobite; N. sabina, known only from caves in San Luis Potosi, is redescribed and illustrated. Newportia azteca is revived and returned to its rightful position as the third oldest name in the genus; despite having priority by 27 years, it had been considered to be “the same” as N. spinipes and dropped from nomenclature. Although Newportia and the Newportiinae are not known from the continental United States, they do inhabit the country’s territories in the Caribbean; N. heteropoda Chamberlin, 1918, is reported from Puerto Rico, and N. longitarsis virginiensis Lewis, 1989, is recorded from St. Thomas and St. Croix, US Virgin Islands, and Tortola and Virgin Gorda, British Virgin Islands. The northernmost Mexican record, of N. pelaezi in Nuevo León, is only 96 mi (154 km) south of the US border, suggesting that the taxa may potentially be discovered in the southern periphery of Texas; likewise, rafting from Cuba, where 4–5 species occur, could bring them to the Florida Keys. New localities from Mexico are presented for N. stolli, N. spinipes, N. oreina, N. atoyaca, and N. morela, and ranges are depicted on a distribution map.

A comprehensive molecular study, using sequence data from nuclear ITS rDNA and plastid rbcL and matK exons, rps16 intron, and the trnL-F intronic and intergenic spacer, was used to assess the taxonomic status of Thecanthes Wikstr., and to evaluate the relationships within Pimelea Banks & Sol. ex Gaertn. and Thecanthes (Thymelaeaceae). Both genera are Australasian and they constitute the subtribe Pimeleinae, which is characterised by a reduction to two stamens. Previous studies indicated a close relationship among Pimelea, Thecanthes and Gnidia L. species from tropical Africa. We conclude that Pimelea and Thecanthes form a strongly supported clade, with Thecanthes possibly included within Pimelea, although we await further data before formally proposing a series of new taxonomic combinations.
