The Relationship

Boldness and aggressiveness are crucial behavioral traits in the field of animal personality, and both have important ecological and evolutionary significance. As swimming crabs (Portunus trituberculatus) are aggressive, their production is affected; thus, it is important to study their behavior. To assess the relationship between boldness and aggressiveness of male P. trituberculatus and the differences between their different life stages, we determined the individual differences in these two traits in juvenile and adult crabs under laboratory conditions. Based on the k-means cluster analysis, boldness of crabs is classified according to their rush to adventure, and aggressiveness of crabs is classified according to their aggressive behavior toward conspecifics. The results show that the personality classification of juvenile and adult crabs was consistent. Boldness was divided into three levels: bold, middle, and shy. Aggressiveness was divided into two levels: aggressiveness and non-aggressiveness. The personality of juveniles and adults P. trituberculatus males was significantly different; juveniles presented higher aggressiveness and lower boldness than adults. Additionally, a significant positive correlation between boldness and aggressiveness of adult crabs was verified (P = 0.001, ρ = 0.271). However, this correlation in juvenile crabs was not significant (P = 0.702, ρ = 0.042). These preliminary results indicate that the personality of P. trituberculatus males has developmental plasticity and adults have the boldness-aggressiveness behavioral syndrome.

A soil actinomycete, strain 80-133T, with the non-validly published name ‘Microstreptospora cinerea’, was the subject of a polyphasic study designed to clarify its taxonomic status. Comparative 16S rRNA gene sequence studies indicated that the organism belonged to the genus Streptomyces, a result in line with previous chemotaxonomic and morphological data. The strain belonged to the Streptomyces griseus clade, but could be distinguished from representatives of species assigned to this taxon by using DNA–DNA relatedness and phenotypic data. In light of these findings, it is proposed that the organism should be recognized as a novel species of the genus Streptomyces. The name proposed for this taxon is Streptomyces yanii sp. nov., with isolate 80-133T (=AS 4.1146T=JCM 3331T) as the type strain. It was also shown that representative strains of Streptomyces argenteolus, Streptomyces caviscabies, S. griseus and Streptomyces setonii belong to the same genomic species and have key phenotypic properties in common. It is proposed that S. caviscabies and S. setonii should be considered as later heterotypic synonyms of S. griseus and that S. argenteolus AS 4.1693T should also be assigned to this taxon.

Taxonomic Point

Phoebis Hübner (1819) is a genus of the Neotropical subfamily Coliadinae (Lepidoptera: Pieridae). The highest diversity is found in the Greater Antilles islands in the Caribbean region. Although from the taxonomic point of view, Phoebis seems to be a stable genus, there is no phylogenetic hypothesis corroborating the monophyly of the genus. In this study, we used both morphological characters and a genetic dataset consisting of one mitochondrial (COI) and three nuclear markers (RpS5, MDH, Wingless). The matrix was concatenated and analysed with parsimony under implied weights (IW). Also, the concatenated data set was analysed using maximum likelihood and Bayesian inference evolutionary methods, and ancestral states reconstruction with characters traditionally used for classification of Phoebis was carried out. The same topology was recovered by Parsimony, ML and BI analysis, and suggest that Phoebis is not a monophyletic genus, with Aphrissa and Rhabdodryas nested within it. Our findings allow us to consider the genera Rhabdodryas syn.rev. and Aphrissa syn.rev. to be synonyms of Phoebis. These results have implications for the systematics of Phoebis and the genera that should be accepted in Coliadinae.

Morphological data on the larvae of 37 species of freshwater mites (Hydrachnidia) known from springs in Luxembourg are reported. Larvae of Sperchon insignis (Walter, 1906), S. longissimus K.Viets, 1920, Lebertia holsatica K. Viets, 1920, Atractides fonticolus (K.Viets, 1920) and, with a question mark, A. pennatus (K.Viets, 1920) are described for the first time; re-descriptions are presented for Sperchon squamosus Kramer, 1879 and S. setiger Thor, 1898. Previous larval descriptions are listed and commented on for all species. Two species are recorded as new for the Luxembourgian fauna: Panisellus thienemanni (K.Viets, 1920) and Pseudofeltria scourfieldi Soar, 1904. A further taxon previously not recorded from springs in Luxembourg is described, probably Tiphys Koch, 1836 sp. An illustrated key is presented suitable for the determination of most parasitic water mite larvae attached to insect hosts from Luxembourgian springs.

Morphological And Molecular Data

Based on a specimen found at Montagne d'Ambre in northern Madagascar morphologically agreeing with Compsophis albiventris Mocquard, 1894, we report on the rediscovery of this enigmatic snake genus and species and its molecular phylogenetic relationships. Compsophis albiventris, considered to be the only representative of its genus and unreported since its original description, bears strong morphological similarities to species of Geodipsas Boulenger, 1896. A molecular phylogeny based on DNA sequences of three mitochondrial and nuclear genes (complete cytochrome b, fragments of 16S rRNA and c-mos) in Compsophis albiventris and three Geodipsas species corroborated close relationships between C. albiventris and Geodipsas boulengeri, and showed that the genera Compsophis and Geodipsas together form a monophyletic unit. Despite the general similarities, morphological data and chromatic features support the existence of two species groups, corresponding to Compsophis and Geodipsas. We consequently consider Geodipsas as a subgenus of Compsophis and transfer all species currently in Geodipsas into the genus Compsophis.

A New Species

The generic classification of Neotropical Eumeninae has been termed chaotic, and synonymisation of taxa has become constant in recent years. Recognition of some generic limits are problematic due to features showing a great deal of variation, such as the length of the first metasomal tergum. This applies to the Neotropical Alphamenes van der Vecht, Minixi Giordani Soika and Pachyminixi Giordani Soika. Minixi has already been demonstrated to be paraphyletic in regards to Pachyminixi. These taxa are the focus of the present study, which used morphological data to infer the phylogenetic relationships among their constituent species. A total of 14 taxa and 34 characters were subjected to cladistic analysis under implied weighting. A single most-parsimonious cladogram was obtained, recovering Pachyminixi as monophyletic. Minixi, however, was paraphyletic relative to Pachyminixi and they are thus synonymised, with the former name having priority. A new species from Mexico, Minixi mariachii, sp. nov., is described. Minixi joergenseni bicingulatus (Zavattari, 1912) is synonymised under M. joergenseni (Schrottky, 1909), comb. nov. Additional new combinations are: Minixi arechavaletae (Brèthes, 1903), comb. nov., M. bifasciatum (von Schulthess, 1904), comb. nov., M. brethesi (Bertoni, 1927), comb. nov., M. sumichrasti (de Saussure, 1875), comb. nov., and M. uruguyense (de Saussure, 1855), comb. nov. Illustrations and a new key to species of Minixi are provided. The present study enhances our knowledge on Neotropical potter wasp systematics, providing one further step into a natural classification for a group whose taxonomy has suffered from irrational splitting of genera in the past century.

AbstractCurrently, the Cochlostoma (Holcopoma) westerlundi (Paulucci, 1879) group includes three subspecies inhabiting southern Italy up to southeastern Sicily. C. w. westerlundi (Paulucci, 1879) is limited to southern Calabria, C. w. yapigium (Westerlund, 1885) is widespread across the Salento (the southeastern extremity of the Apulia region) and C. w. dionysii (Paulucci, 1879) is endemic to the environs of Siracusa (SE Sicily). There is also a fourth taxon, C. paganum (Westerlund, 1885) described for Otranto (LE, Apulia), considered a synonym of C. w. yapigium. Up to now, the molecular genetics of C. westerlundi s.l. have been unknown and the morphological data of several populations are still lacking. Hence, the systematic classification of the group is tentative. Aiming at filling this gap, mtDNA (16S rDNA and COI) partial sequences were investigated and, in addition, the reproductive apparatus of C. w. westerlundi was described for the first time. Molecular sequences and anatomical data were used to test the taxonomic and phylogenetic status of the examined populations. Maximum Likelihood and Bayesian analysis revealed three clusters, strongly supported, corresponding to the three taxa. For the first time, synonymy between paganum and yapigium was confirmed by molecular evidence. Genetic distances between groups (DxyJC) ranged from 2.6% to 5% (16S rDNA) and from 6.3% to 8.3% (COI). Molecular and morphological data led us to suggest elevating the three subspecies to the species rank.
