An overview of the Riodinidae of western New Guinea is given. In particular, the species described by Toxopeus (1944), which have remained largely unknown due to a lack of illustrations, are considered. Type specimens of all species described by Toxopeus are illustrated for better evaluation and comparison with closely related forms. Lectotypes of...

Jamides willneri sp. nov. is described in detail and illustrated with its genitalia on the basis of a single male specimen from the East Sepik Province of Papua New Guinea. The new species is assigned to the Jamides bochus (Stoll, [1782]) species-group, but does not match any species described from Papua New Guinea. It is compared with the closely...

Butterflies are a diverse and charismatic insect group that are thought to have evolved with plants and dispersed throughout the world in response to key geological events. However, these hypotheses have not been extensively tested because a comprehensive phylogenetic framework and datasets for butterfly larval hosts and global distributions are la...

Based on molecular as well as on morphological characters, it is concluded that Hypochrysops hypocletus Oberthür, 1880 has to be treated as separate species and not a synonym of H. polycletus (Linnaeus, 1758): Hypochrysops hypocletus Oberthür, 1880 stat. nov.

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...

Report: Devonian Rugose corals and Pelogeography in Central Asia.

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...

In the locality of Colle (Cantabrian Zone, NW Spain), the upper part of the Valporquero Shale Formation (Emsian, La Vid Group) contains an interval of shales and marlstones (barren, greenish-grey shales and fossiliferous, greenish-grey or reddish shales/marlstones) with beds and packages of homogeneous and cross-bedded skeletal limestones. Metre-sc...

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 Paleozoic sequences of the Padaukpin area of the Northern Shan States (Union of Myanmar) and the Baoshan region in Western Yunnan (P. R. of China) are compared. They show many similarities. A hiatus in sedimentation during the Carboniferous is developed in both regions and is therefore of regional importance. The Middle Devonian rugose coral fa...

Two species of Lower Devonian rugose corals are described from the Cantabrian Mountains of Spain: Cantabriastraea cantabrica gen. et sp. nov. and Tabulophyllum bonarense sp. nov. The development of root- or buffer-like attachment structures ("rhizoid processes") in T. bonarense indicates adaption to the soft substrate and supports corallite stabili...

Seven Tabulophyllum-species of the European Devonian are revised and two species are described as new. Tabulophyllum lineatum (QUENSTEDT 1881) from the Sudetes is redescribed and taxonomically fixed by designating a lectotype. Tabulophyllum rotundum FENTON & FENTON 1924, T. sylvaticum ROHART 1988 and probably T. normale (WALTHER 1928) are synonyma...

Rugose corals are described for the first time from the Givetian and Frasnian of the central Pamir Mountains near the Rabatakbaytal area, Tadjikistan. In addition to Hexagonaria reedi sp. nov., Radiophyllum?, Temnophyllum and Disphyllum are recorded. The occurrence of a new species of Hexagonaria and a probable Radiophyllum suggest a possible fauna...

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...

Abstract Two insufficiently known Middle Devonian columnariid species from the collection ofC. Schlüter are redescribed and figured for the first time.Columnaria devonica Schlüter 1889 is regarded as conspecific withC. sulcata Goldfuss 1826, andSpongophyllum tabulosum Schlüter 1889 has to be treated as valid name for the younger synonymColumnaria c...

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...

Die mitteldevonische rugose Korallen-ArtBattersbyia varia (Schlüter 1889) wird revidiert. Die bislang zu dieser Art gestellten Funde haben sich als nicht konspezifisch erwiesen und gehören einer bisher unbeschriebenenXystriphyllum-Art an, die nahe mitXystriphyllum implicatum (Tsien 1969) verwandt ist. Eventuell muß dieses Taxon in zwei Unter-Arten...
