Taxonomic Implications

The classification and phylogenetic relationships of the genus Blarinella have been traditionally based on morphologicalcharacteristics, and there have been no studies published about the molecular phylogenetic relationships and biogeographyfor this genus. Here, we reconstructed the phylogenetic relationships of the genus Blarinella based on one nuclear (ApoB)and two mitochondrial (cyt-b, 16S rRNA) genes. Our results supported the monophyly of the genus Blarinella and thevalid species status of Blarinella wardi. Nevertheless, two morphologically defined Blarinella species, B. quadraticaudaand B. griselda, were poorly differentiated by molecular data; B. quadraticauda was found embedded within B. griseldamaking the latter a paraphyletic group. These results indicate that B. quadraticauda might be under a budding speciationscenario or is a restricted geographical subspecies of B. griselda. Phylogeographic analyses suggest that diversificationand speciation of Blarinella might have been promoted by vicariance events associated to the complex topography of Southwest China. Further morphological, genetic and ecological studies are necessary to examine these hypotheses.

A recent nomenclatural change based on molecular data (Duellman et al. 2016) resurrected genus Ololygon to accommodate all taxa in the former Scinax catharinae clade (Faivovich 2002; Faivovich et al. 2005). Most Ololygon species inhabit Coastal Atlantic rainforests in northeastern and southeastern Brazil (Duellman et al. 2016), but some species occur in the Cerrado Domain (Cardoso & Haddad 1982; Pombal et al. 2010; Lourenço et al. 2013). Ololygon pombali (Lourenço, Carvalho, Baêta, Pezzuti & Leite, 2013) is a small species only known from the southern portion of Parque Nacional da Serra da Canastra, in the municipality of Capitólio, state of Minas Gerais, southeastern Brazil. Here, we describe the vocal repertoire of Ololygon pombali and provide notes on dorsal color pattern variation, while briefly discussing their taxonomic implications.

AbstractAlthough the infratribal classification of the Lactuceae has been the focus of several studies, relationships between the genera are not yet fully resolved. While trichome characters have been shown to be an important tool in taxa delimitation in many plant families, a detailed study on trichomes within the Lactuceae was still lacking. We assess here how trichome types can contribute to the clarification of generic relationships in this tribe. Trichome diversity was investigated on stems and leaves of 135 representatives of 53 genera by light and scanning electron microscopy. According to their morphology and anatomy, trichomes were classified into eight types and several subtypes. Phenetic analysis based on the presence or absence of particular trichome types was performed. The previously supposed monophyly of exclusively American genera and affinities between several closely related genera were confirmed. A new circumscription of the subtribe Hieraciinae is proposed, in accordance with recent molecular data. According to the present study, this subtribe is characterized by a unique combination of two trichome types and comprises the following genera: Andryala, Hieracium, Hispidella, Pilosella, Stenotheca. The previously included genera Arnoseris, Hololeion and Tolpis do not belong to this assemblage and their removal from the Hieraciinae should be reconsidered.

Historical Issues

Members of the New Zealand Enantiobuninae constitute some of the most charismatic soil arthropods of the archipelago, and a striking example of sexual dimorphism, with nondescript females but colourful males boasting exaggerated chelicerae many times longer than their bodies. The genera Forsteropsalis and Pantopsalis recently underwent revision, but many questions remained about the validity of species designations owing to historical issues of characters of dubious taxonomic value, female specimens designated as holotypes despite the males holding all the diagnostic characters, and the suspected presence of more than one male form within some species. We present the first phylogeny based on molecular data for the New Zealand species in the genera Forsteropsalis, Pantopsalis and Mangatangi, and comment on the taxonomic implications of our results, including the diagnostic viability of important morphological characters. Our analyses reject the monophyly of Neopilionidae and Forsteropsalis, but support the monophyly of Pantopsalis. Finally, we comment on the taxonomic implications of the results, including the diagnostic validity of morphological characters traditionally used on the groups.

Mitochondrial 16S Rrna Gene

Micryletta inornata (Boulenger 1890), the type species of the genus Micryletta, was originally described from the island of Sumatra in Indonesia. Subsequently, this species has been widely reported from Sundaland (Sumatra and Malay Peninsula), Indo-China, Northeast India and South Andaman, up to southern China and Taiwan. However, since the original description there has been no further report of this species from the type locality or the island. During a herpetofaunal survey in Sumatra, several specimens that are morphologically concordant with the original description and the syntypes of M. inornata were found, and thus the species was rediscovered after 125 years. Here, we provide a redescription of the species based on the freshly collected specimens, along with a detailed morphological and molecular comparison with known congeners. Further, using molecular data from the mitochondrial 16S rRNA gene, our study recovered the Sumatran M. inornata as a phylogenetically distinct lineage from all other populations previously referred to this species. This confirms that all known Micryletta ‘inornata’ populations from regions outside Sumatra constitute several other lineages representing either new species or previously available names currently considered as synonyms, consequently requiring taxonomic validation in the future.

Proclossiana Eunomia

The Proclossiana eunomia (Esper, 1799) complex is currently composed of the several subspecies distributed throughout Palaearсtic region and North America. Despite the fact that some of the taxa have differences in wing pattern and body size, previous assumptions on taxonomy not supported by molecular data. Therefore, the identity of certain populations of this complex has remained unclear and the taxonomic status of several recently described taxa is debated. Here, we provide insights into systematics of some Palaearctic members of this group using molecular approach, based on the analysis of the barcoding fragment of the COI gene taking into account known morphological differences.

Morphological And Molecular Data

The recent catalogues of the family Dolichopodidae considered Syntormon pallipes (Fabricius, 1794) and S. pseudospicatus Strobl, 1899 as separate species. In this study, we used three approaches to estimate the significance of differences between the two species: molecular analysis (COI and 12S rRNA sequences), analysis of leg colour characters and geometric morphometric analysis of wing shape. The morphological data confirmed the absence of significant differences between S. pallipes and S. pseudospicatus found in the DNA analysis. Significant differences in the wing shape of two species have not been revealed. Hence, according to our data, there is no reason to consider S. pseudospicatus as a distinct species.

OBJECTIVEIntraoperative seizures during craniotomy with functional mapping is a common complication that impedes optimal tumor resection and results in significant morbidity. The relationship between genetic mutations in gliomas and the incidence of intraoperative seizures has not been well characterized. Here, the authors performed a retrospective study of patients treated at their institution over the last 12 years to determine whether molecular data can be used to predict the incidence of this complication.METHODSThe authors queried their institutional database for patients with brain tumors who underwent resection with intraoperative functional mapping between 2005 and 2017. Basic clinicopathological characteristics, including the status of the following genes, were recorded: IDH1/2, PIK3CA, BRAF, KRAS, AKT1, EGFR, PDGFRA, MET, MGMT, and 1p/19q. Relationships between gene alterations and intraoperative seizures were evaluated using chi-square and two-sample t-test univariate analysis. When considering multiple predictive factors, a logistic multivariate approach was taken.RESULTSOverall, 416 patients met criteria for inclusion; of these patients, 98 (24%) experienced an intraoperative seizure. Patients with a history of preoperative seizure and those treated with antiepileptic drugs prior to surgery were less likely to have intraoperative seizures (history: OR 0.61 [95% CI 0.38–0.96], chi-square = 4.65, p = 0.03; AED load: OR 0.46 [95% CI 0.26–0.80], chi-square = 7.64, p = 0.01). In a univariate analysis of genetic markers, amplification of genes encoding receptor tyrosine kinases (RTKs) was specifically identified as a positive predictor of seizures (OR 5.47 [95% CI 1.22–24.47], chi-square = 5.98, p = 0.01). In multivariate analyses considering RTK status, AED use, and either 2007 WHO tumor grade or modern 2016 WHO tumor groups, the authors found that amplification of the RTK proto-oncogene, MET, was most predictive of intraoperative seizure (p < 0.05).CONCLUSIONSThis study describes a previously unreported association between genetic alterations in RTKs and the occurrence of intraoperative seizures during glioma resection with functional mapping. Future models estimating intraoperative seizure risk may be enhanced by inclusion of genetic criteria.
