Butterflies are a diverse and charismatic insect group that are thought to have diversified via coevolution with plants and in response to dispersals following key geological events. These hypotheses have been poorly tested at the macroevolutionary scale because a comprehensive phylogenetic framework and datasets on global distributions and larval...

An overview is given of the species of the lycaenid genus Danis Fabricius, 1807, occurring in West Papua and Papua (Indonesia). All taxa are discussed with regard to their systematic position and-as far as possible-the type specimens of several species are shown for the first time. Particular emphasis is placed on the individual characters that are...

Difficulties in separating males of A. herculina (Staudinger, 1888) and A. leo (Druce, 1894) made it desir­able to investigate the relationship of both taxa using DNA analysis. Differences in mitochondrial COI gene and in the nuclear Ef­1α gene sequences appear to be very low (0–0.15%), indicating that only one species with two female phenotypes is...

Morphological studies of androconia were performed for 13 Celastrina species using a digital microscope with Z-stacking mode. Whereas C. ladon lacked androconia, the remaining 12 species were found to possess fan-shaped androconia on the dorsal wing surfaces. The androconia of these species shared the following common features: smaller size than st...

Macgeea is a cosmopolitan genus of Devonian rugose corals that includes numerous, generally highly variable, species. Because of its wide skeletal variation and additional trabecular dilation it is difficult to recognize taxonomically relevant characters and to separate those from ecologically induced modifications. The high variability is probably...

The descriptive terms “Leperditien-Kalke” and “Klotzige Bank-Kalke” were introduced byKräusel (1953) during the reinvestigation of the Dollendorfer Mulde and describe two lower Givetian limestone intervals, each of about 15 to 20 m thickness. As none of those limestones yield biostratigraphically relevant macrofaunas, the age of both deposits can b...

The Middle Devonian rugose coral species Battersbyia varia (Schluter 1889) is revised. Specimens recently regarded as conspecific belong to an undescribed species of Xystriphyllum, which is closely related to Xystriphyllum implicatum (Tsien 1969). This species should most probably be split into two subspecies (or morphotypes?) because of very diffe...

The distribution of several fossil groups from the Middle Devonian of the Eifel region suggest that it may be subdivided into three "faunal regions" (North-, West- and South-Eifel).
