Abstract The systematics and taxonomy of the broadly distributed bats of the genus Cynomops has changed considerably in the last few years. Among the major changes, Cynomops abrasus was split into two species of large-bodied forms (Cynomops mastivus and C. abrasus) distributed east of the Andes. However, large Colombian specimens identified as C. abrasus from the western side of the Andes had yet to be included in any revisionary work. Phylogenetic analysis performed in this study, using mtDNA sequences (Cytochrome-b), revealed that these Colombian individuals are more closely related to Cynomops greenhalli. Morphological and molecular data allowed us to recognize populations from western Colombia, western Ecuador and northwestern Peru, as members of a new species of Cynomops. Characters that allow for its differentiation from C. greenhalli include a larger forearm, paler but more uniform ventral pelage, more globular braincase, and well-developed zygomatic processes of the maxilla (almost reaching the postorbital constriction). This study serves as another example of the importance of including multiple lines of evidence in the recognition of a new species. Given its rarity and the advanced transformation of its habitat, this new species is particularly important from a conservation perspective.

The New Zealand spider Clubiona blesti Forster, 1979 is redescribed, with the male described for the first time, and a pre-liminary molecular phylogenetic analysis of cytochrome c oxidase subunit I (COI) mtDNA sequences for eight species ofNew Zealand Clubiona and an outgroup from Tasmania is presented.There is considerable intraspecific variation in C. blesti, both genetic and in the morphology of copulatory organs,which may be explained by its wide distribution. The lack of a geographic structure based on consistent differences be-tween populations may suggest great dispersal ability. Given the limited sample size, further sampling and data on addi-tional genetic markers will be necessary to confirm this.The phylogenetic analysis of seven more species indicated that Clubiona cambridgei is the sister species of C. blestiand confirmed the existence of at least two monophyletic groups among the New Zealand Clubiona: species with a striped abdomen and with a spotted abdomen.

Similarities And Differences

Morphological characters, as presently applied to describe members of the Paguristes tortugae Schmitt, 1933 species complex, appear to be of limited value in inferring phylogenetic relationships within the genus, and may have similarly misinformed understanding of relationships between members of this complex and those presently assigned to the related genera Areopaguristes Rahayu & McLaughlin, 2010 and Pseudopaguristes McLaughlin, 2002. Previously undocumented observations of similarities and differences in color patterns among populations additionally suggest genetic divergences within some species, or alternatively seem to support phylogenetic groupings of some species. In the present study, a Maximum Likelihood (ML) phylogenetic analysis was undertaken based on the H3, 12S mtDNA, and 16S mtDNA sequences of 148 individuals, primarily representatives of paguroid species from the western Atlantic. This molecular analysis supported a polyphyletic Diogenidae Ortmann, 1892, although incomplete taxonomic sampling among the genera of Diogenidae limits the utility of this finding for resolving family level relationships. Several hypotheses regarding the evolutionary relationships among hermit crab genera were refuted by the Kishino-Hasegawa (KH). Shimodaira-Hasegawa (SH) and Approximately Unbiased (AU) tree topology tests, among them the hypothesis that Areopaguristes is monophyletic. A lack of support for the monophyly of Areopaguristes calls into question the phylogenetic validity of gill number for the differentiation of Paguristes, Areopaguristes, and Pseudopaguristes. The study was inconclusive with regard to the relationships among these three genera, but previously unknown diversity within both Paguristes and Areopaguristes was demonstrated. Existence of an undescribed species confounded under the name Paguristes tortugae Schmitt, 1933 was supported by genetics, morphology, and coloration. A second undescribed species with remarkable similarity to Areopaguristes hummi Wass, 1955 was discovered based on genetics and coloration.

SummaryThe phylogenetic analysis of partial SSU, LSU (rDNA) and COI (mtDNA) sequences was performed for the quimperiid nematode Ichtyobronema hamulatum, a common parasite of the burbot Lota lota. The study of SSU (for 2007 bp long alignment) has shown that in all kinds of analyses I. hamulatum cluster with Paraquimperia africana (Quimperiidae), while another quimperiid, Paraseuratum sp., unites in a separate clade with Spectatus spectatus (Kathlaniidae). Both groups do not form direct phylogenetic links with the rest of seuratoid nematodes (i.e. Cucullanidae and Seuratidae). Obtained data (for 1080 bp long alignment) exhibit the phylogenetic affinity of I. hamulatum and P. africana with kathlaniids of the genus Falcaustra. The analysis of LSU sequences has revealed that I. hamulatum occupies the basal position in relation to all other members of Spirurina and Rhabditina.

Comprehensive Study

Previous observations suggest that the mitochondrial (mt)DNA may confer susceptibility to multiple sclerosis (MS). However, the proportion of affected individuals and the range of contributing mtDNA abnormalities are unknown. To help clarify this question, we analyzed the first hypervariable D-loop sequences of the mtDNA in a group of randomly selected Caucasian MS patients, in MS patients with prominent optic neuritis (PON) and in controls. Phylogenetic analysis of these D-loop sequences revealed that individuals in both groups of patients are generally scattered in the Caucasian phylogeny. However, a small cluster of unrelated MS patients identified by this analysis suggests that a maternal lineage with MS relevant mtDNA sequences may exist, and merits a more comprehensive study.

AbstractKolomyjec et al. (2020). Phylogenetic analysis of Michigan’s freshwater sponges (Porifera, Spongillidae) using extended COI mtDNA sequences. – Zoologica Scripta, 00, 000-000. The phylogenetic relationships of eight species of freshwater sponges sampled throughout the State of Michigan in the North American Great Lakes region were examined as part of a Course-based Undergraduate Research Experience (CURE). An extended version of the standard cytochrome oxidase subunit I (COI) metazoan DNA was used for sequencing and Bayesian phylogenetic inference. The extended gene region (COI-ext) produces a 1,200 bp amplicon instead of the standard 640 bp fragment which compensates for the standard amplicon’s low informatics value in Phylum Porifera. The species examined clustered into strongly supported monophyletic species groups within the family Spongillidae. This study represents the first look at the phylogenetic relationships of freshwater sponges in the Great Lakes Region.Per Kolomyjec, College of Science and the Environment, Lake Superior State University, 650 W Easterday Ave., Sault Sainte Marie, MI 49783, USA.

The Neotropics harbor an enormous diversity of tachinid flies (Diptera: Tachinidae), yet the fauna remains poorly understood. This is especially true of the tribe Blondeliini, which is particularly diverse in this region and in great need of taxonomic attention. Here, the Neotropical blondeliine genus Erythromelana Townsend is revised. This genus is widely distributed from southern Mexico to northern Argentina, with the Andes being a hotspot of diversity. Known hosts belong to the genus Eois Hübner (Lepidoptera: Geometridae). This revision includes the redescription of three previously described species and the description of 11 new species based on characteristics of adults and immatures. The new species are E. arciforceps sp. nov., E. catarina sp. nov., E. convexiforceps sp. nov., E. cryptica sp. nov., E. curvifrons sp. nov., E. distincta sp. nov., E. ecuadoriana sp. nov., E. eois sp. nov., E. leptoforceps sp. nov., E. napensis sp. nov., and E. woodi sp. nov. A morphological database of 62 characters was constructed to assess morphological variation within and among species and species groups using Principal Components Analysis. Means and medians for these morphological traits were calculated to infer phylogenetic relationships using parsimony. Additionally, a maximum likelihood phylogenetic analysis was performed using COI mtDNA sequences for a subset of eight species. Nominal species E. obscurifrons (Wulp) is treated as a nomen dubium within Erythromelana. Two species previously assigned to Erythromelana appear to represent distinct genera with unclear relationships to this genus and are reinstated as monotypic genera: Myiodoriops marginalis Townsend and Euptilodegeeria obumbrata (Wulp), revived status. Biological and phylogenetic data are used to infer modes of diversification within Erythromelana.
