A list of the species described and pictures of 13 primary and secondary types are presented. A synthesis of his classification is given, with comments and comparison to modern classification.
ABSTRACT
An illustrated catalogue of the Palaearctic types of species and subspecies described by Walter Linsenmaier in the genus Hedychridium Abeille de Perrin, 1878 is given. Linsenmaier described 110 species and subspecies of Hedychridium, most of the holotypes are deposited in his collection, at the Natur-Museum (Luzern, Switzerland), with the exception of 25 holotypes which are deposited at the Bristish Museum (London), at the Muse cantonal de zoologie (Lausanne) and in two private collections. Hedychridium atratum is here transferred to Chamaeholopyga Linsenmaier, 1987. Hedychridium krajniki turceyense Linsenmaier, 1968 stat. nov. is upgraded to species rank. The holotype of Hedychridium caireanum Linsenmaier, 1968 is considered lost. A list of the species described and a synthesys of his classification is given. Pictures of 83 primary and secondary types are presented.

An illustrated catalogue of the Palaearctic types of species and subspecies described by Walter Linsenmaier in the genus Hedychrum Latreille, 1802 is given. Linsenmaier described 14 taxa of Hedychrum; almost all primary types are deposited in the collection, at the Natur Museum (Luzern, Switzerland), with the exception of two holotypes which are deposited at the Natural History Museum (London), and Naturalis (Leiden). Hedychrum mithras Semenov-Tian-Shanskij, 1967 spec. resurr. is revalidated from the previous synonymy with Hedychrum luculentum bytinskii Linsenmaier, 1959. A list of the species described and pictures of the holotypes and allotypes deposited in the collection are given.

Historical notes on Walter Linsenmaier, his entomological career and his Chrysididae collection are given. The purpose of this article is to supply the main results obtained during the GBIF digitalization project and the subsequent reorganization of the Chrysididae collection housed in the Natur-Museum Luzern (Switzerland); we also provide the complete list of the 720 taxa described by the Swiss author (species-group and genus-group names). Observations on the type material is given. A new synonymy (valid name is first) is proposed for: C. consanguinea Mocsáry, 1889 = C. consanguinea iberica Linsenmaier, 1959, syn. nov.; C. pyrophana Dahlbom, 1854 = C. pyrophana var. orionea Linsenmaier, 1951, syn. nov.; Hedychridium elegantulum du Buysson, 1887 = H. hybridum Linsenmaier, 1959, syn. nov.; H. perpunctatum Balthasar, 1953 = H. insequosum Linsenmaier, 1959, syn. nov.; Euchroeus (Pseudospinolia) incrassatus (Spinola, 1838) = E. (P.) humboldti jerichoensis Linsenmaier, 1959, syn. nov. A new replacement name Chrysis vulcanica Rosa, nom. nov. is proposed for Chrysis brevicollis Linsenmaier, 1987, nom praeocc., nec Mocsáry, 1899. The lectotype of Chrysis auriceps Linsenmaier, 1959 is designated.

The 60 000 described species of Cyclorrhapha are characterized by an unusual diversity in larval life-history traits, which range from saprophagy over phytophagy to parasitism and predation. However, the direction of evolutionary change between the different modes remains unclear. Here, we use the Scathophagidae (Diptera) for reconstructing the direction of change in this relatively small family (≈ 250 spp.) whose larval habits mirror the diversity in natural history found in Cyclorrhapha. We subjected a molecular data set for 63 species (22 genera) and DNA sequences from seven genes (12S, 16S, Cytb, COI, 28S, Ef1-alfa, Pol II) to an extensive sensitivity analysis and compare the performance of three different alignment strategies (manual, Clustal, POY). We find that the default Clustal alignment performs worst as judged by character incongruence, topological congruence and branch support. For this alignment, scoring indels as a fifth character state worsens character incongruence and topological congruence. However, manual alignment and direct optimization perform similarly well and yield near-identical trees, although branch support is lower for the direct-optimization trees. All three alignment techniques favor the upweighting of transversion. We furthermore confirm the independence of the concepts "node support" and "node stability" by documenting several cases of poorly supported nodes being very stable and cases of well supported nodes being unstable. We confirm the monophyly of the Scathophagidae, its two constituent subfamilies, and most genera. We demonstrate that phytophagy in the form of leaf mining is the ancestral larval feeding habit for Scathophagidae. From phytophagy, two shifts to saprophagy and one shift to predation has occurred while a second origin of predation is from a saprophagous ancestor.
ABSTRACT
Genetic relationships among 62 Vibrio vulnificus strains of different geographical and host origins were analyzed by multilocus enzyme electrophoresis (MLEE), random amplification of polymorphic DNA (RAPD), and sequence analyses of the recA and glnA genes. Out of 15 genetic loci analyzed by MLEE, 11 were polymorphic. Cluster analysis identified 43 distinct electrophoretic types (ETs) separating the V. vulnificus population into two divisions (divisions I and II). One ET (ET 35) included all indole-negative isolates from diseased eels worldwide (biotype 2). A second ET (ET 2) marked all of the strains from Israel isolated from patients who handled St. Peter's fish (biotype 3). RAPD analysis of the 62 V. vulnificus isolates identified 26 different profiles separated into two divisions as well. In general, this subdivision was comparable (but not identical) to that observed by MLEE. Phylogenetic analysis of 543 bp of the recA gene and of 402 bp of the glnA gene also separated the V. vulnificus population into two major divisions in a manner similar to that by MLEE and RAPD. Sequence data again indicated the overall subdivision of the V. vulnificus population into different biotypes. In particular, indole-negative eel-pathogenic isolates (biotype 2) on one hand and the Israeli isolates (biotype 3) on the other tended to cluster together in both gene trees. None of the methods showed an association between distinct clones and human clinical manifestations. Furthermore, except for the Israeli strains, only minor clusters comprising geographically related isolates were observed. In conclusion, all three approaches (MLEE, RAPD, and DNA sequencing) generated comparable but not always equivalent results. The significance of the two divisions (divisions I and II) still remains to be clarified, and a reevaluation of the definition of the biotypes is also needed.
