Arachnida

Reiter

Info

From a curatorial perspective, this section represents not only the arachnids but also the 'basal' hexapods (primarily wingless insects, mayflies, odonates), as well as pantopods and crustaceans. The collections hold about 70,000 specimens. Our research focuses on spider taxonomy, phylogeny, and biology as well as on function and evolution of arthropod genitalia.

Flight strategies and wing parameters in North American dragonflies (Odonata)

Wing morphology is largely shaped by intra-, intersexual and natural selection.Dragonfly wings are subject to various selection pressures. Territoriality, courtship displays, different kinds of mating systems, seasonal migrations, foraging behavior and other aspects of dragonfly life history and behavior all require specific functional traits of the wing.

Evolution of Ninetinae

This project focuses on the spider subfamily Ninetinae, tiny cryptic ground-dwellers that are largely restricted to arid habitats. They seem to be ‘basal’ within Pholcidae and thus crucial for reconstructing the evolutionary history of the family.

Establishing a standardized and universally applicable set of nuclear-encoded markers for genome-wide multi-locus species delimitation of metazoans

Methods for delimiting species based on multi-gene nucleotide information are well established and provide the means to complement the classical COI barcoding approach, whose limitations are well known. Our research project aims at establishing a standardized set of single-copy nuclear-encoded markers for genome-wide multi-locus species delimitation by exploiting comparative genomic data and applying target DNA enrichment. Candidate markers are so-called Universal Single-Copy Orthologs (USCOs).

The pholcid spider collection of González-Sponga

Between 1998 and 2011, the Venezuelan arachnologist Manuel Ángel González-Sponga created a total of 22 new genera for Venezuelan pholcids. Previous efforts to evaluate González-Sponga’s genera were hampered by the inaccessibility of his private collection. As a result, work on Venezuelan pholcid spiders has been almost impossible. After González-Sponga’s death in 2009, his collection was transferred to the Museo del Instituto de Zoología Agrícola in Maracay. The aim of the present project is to initiate collaboration on Venezuelan pholcid spiders and to draft a joint collaborative project on Venezuelan pholcid spider taxonomy and systematics.

Collecting expedition to Ghana

In August 2018, a team of exhibition planners, scientists and taxidermists of the Museum Koenig undertook a collection expedition to the Ankasa River Rainforest Reserve in the southwest of Ghana to collect original plant material for the authentic reproduction of the rainforest canopy habitat in the new Rainforest exhibition.

Egg parasitism in pholcid spiders

Pholcid spider females carry their egg-sacs with their mouthparts until the spiderlings hatch and it is probably for this reason that the eggs are not densely covered by a protective layer of silk as in most other spider families. It seems that few egg parasites have managed to access these protected eggs of Pholcidae. During recent trips in SE Asia several new cases of egg-parasitism in Pholcidae were discovered that will be described in this project.

Southeast Asian pholcid spiders

This project focuses on three major questions : (1) how do Southeast Asian taxa fit into the phylogeny of Pholcidae? (2) Are patterns of diversity and distribution comparable to those in New World and African regions? (3) Is there evidence for a causal relationship between evolutionary shifts among microhabitats and species diversity (adaptive speciation)?

Asymmetry in Panjange

While asymmetric genitalia are very common in insects, they are extremely rare in spiders. This project studies a species group of Panjange spiders from the southern Philippines that has only recently been discovered and in which all species have asymmetric genitalia.

Global pholcid spider diversity

Ratios of known to unknown pholcid spider species collected around the world suggest that only about 20% of the species have been described. Current efforts concentrate on Southeast Asia and Brazil.

Harvestmen genitalia

Harvestmen genitalia are often complex structures that vary among species but little is known about their functioning. We investigate mating behavior, genital morphology as well as interactions of male and female genitalia using histology and X-Ray microtomography of cryo-fixed pairs.

Hotspot Atlantic Forest

Recent collecting trips in the Brazilian Amazon Forest have revealed an extraordinarily rich pholcid fauna. This project aims at documenting this diversity, at exploring its relationships with the faunas of other South American regions, and at comparing diversity and distribution patterns with those in the Brazilian Amazon.

Revision of crab spiders

This project aims at a stable phylogenetic hypothesis for the family Thomisidae by analysis of morphological and DNA sequence data for most taxa of the family. I will use this phylogenetic hypothesis to propose a revised taxonomy for the family, to study the evolution of the diverse behaviors of the family and to test biogeographic hypotheses.

Revision of Smeringopina

With leg spans of up to 18 cm, some Smeringopina species are the largest known pholcids. Nevertheless, the genus is very poorly known and recent expeditions to Guinea, Cameroon, and Gabon have provided more than 30 new species.

Collection

The collections in this section hold about 70,000 specimens, including the worlds most diverse collection of Pholcidae spiders (Huber), extensive spider material from fogging campaigns in East Africa (Wagner, Freund) and from pitfall trapping in West and Central Africa (previously Trier collection), a large and partly historically important Odonata collection, as well as smaller collections of parasitic mites and other Arachnida, Ephemeroptera, Plecoptera, and Crustacea.

Currently the collections are being digitized and prepared for the transfer to Biodiversity Workbench. Preliminary data are available as Excel files:
