Efficient Sequence

DNA barcoding has been recently promoted as a method for both assigning specimens to known species and for discovering new and cryptic species. Here we test both the potential and the limitations of DNA barcodes by analysing a group of well-studied organisms—the primates. Our results show that DNA barcodes provide enough information to efficiently identify and delineate primate species, but that they cannot reliably uncover many of the deeper phylogenetic relationships. Our conclusion is that these short DNA sequences do not contain enough information to build reliable molecular phylogenies or define new species, but that they can provide efficient sequence tags for assigning unknown specimens to known species. As such, DNA barcoding provides enormous potential for use in global biodiversity studies.Key words: DNA barcoding, species identification, primate, biodiversity.

AbstractThis paper focuses on the species diversity among the Trichostrongylidae Leiper, 1912 (Nematoda: Strongylida), and complexity of the family systematics. Polymorphism (subfamilies: Ostertagiinae, Cooperiinae and Haemonchinae), the presence of cryptic species (genus: Teladorsagia) and hybridization (genera: Cooperia, Haemonchus and Ostertagia) are presented and discussed, considering both morphological and molecular evidence. Some of these phenomena are common, nevertheless not sufficiently understood, which indicates the need for expanding the current state of knowledge thereof. Within the Trichostrongylidae, species distinction supported merely by morphological features is difficult, and requires confirmation by means of molecular methods. The parasitic nematode taxonomy is complicated mainly by the genus Teladorsagia, but complexity may also be expected among other Ostertagiinae (e.g. in the genera Ostertagia and Marshallagia). The data presented here show that the members of the Trichostrongylidae can significantly complicate unambiguous species identification. Hence, it is essential to consider the phenomena mentioned, to gather valid and comparable data on the biodiversity of this family.

Gall Midges

Die zur Unterfamilie Micromyinae gehörende Gallmücke Campylomyza serrata wurde vom Autor im Jahre 1998 nach drei Männchen von einem norddeutschen Fundort beschrieben. Seitdem wurden zahlreiche nachträglich gesammelte Exemplare aus mehreren europäischen Ländern dieser Art zugeordnet und als C. serrata publiziert. Nun, fast 20 Jahre später, wurden alle diese Exemplare und einige andere aus bislang undeterminiertem Campylomyza-Material in der Sammlung des Autors – insgesamt 56 Männchen – zusammengezogen und morphologisch nachuntersucht. Im Ergebnis dieser Untersuchung wurde offenbar, dass Campylomyza serrata sensu Jaschhof (1998) ein Komplex aus fünf Kryptospezies ist, einschließlich Campylomyza angulata spec. nov., Campylomyza appendiculata spec. nov., Campylomyza lapponica spec. nov. und Campylomyza zwii spec. nov. In der vorliegenden Arbeit werden Campylomyza serrata und die ihr nahe verwandten Arten aufgrund von Genitalmerkmalen der Männchen definiert. Ein Schlüssel zur Bestimmung der Männchen wird vorgelegt, der die genannten Arten und Campylomyza spinata, den sechsten Vertreter der serrata-Gruppe, einbezieht. Schließlich werden Bestimmungsprobleme diskutiert, wie sie bei der praktischen Arbeit an der serrata-Gruppe (und anderen schwer bestimmbaren Micromyinen) auftreten.StichwörterPalearctic region, gall midges, species identification, morphology, DNA barcoding.Nomenklatorische Handlungenangulata Jaschhof, 2015 (Campylomyza), spec. n.appendiculata Jaschhof, 2015 (Campylomyza), spec. n.lapponica Jaschhof, 2015 (Campylomyza), spec. n.zwii Jaschhof, 2015 (Campylomyza), spec. n.
