The mite species Barbutia arasbaraniensis Mohammad-Doustaresharaf & Bagheri, 2021, until now only known from four specimens from Iran, was discovered in epilithic crustose lichen on the Königstuhl mountain in Heidelberg in Germany. It is designated as the type species of the new taxon Albertibarbutia gen. nov. Based on the new collection material, a supplementary description of the species is provided and facets of its taxonomy and morphology are discussed. The homologies of the setae and solenidia of both the legs and the pedipalps of Albertibarbutia are indicated. The family
Barbutiidae Robaux, 1975 is rediagnosed, its phylogenetic relationships are commented on and it is here recorded for Germany for the first time.
A father's story
(2004)
All across the world, in all walks of life, families everywhere look forward to Summer vacations as a way to spend meaningful time together. When my own children were young, I made it a point every year to take them to someplace exciting and new-Florida and New York in the United States, Switzerland and Italy in Europe, Ecuador and various Colombian cities in South America. I always hoped that, as adults, they would look fondly upon the memories they had of their vacation days with their father and one day do the same with their own children.
We report the unexpected discovery of foliicolous lichen communities at several localities in the Black Forest, south-western Germany, with a total of seven truly or facultatively foliicolous taxa: Bacidina chloroticula, Fellhanera bouteillei, F. subtilis, F. viridisorediata, Fellhaneropsis myrtillicola, Gyalectidium setiferum, and Scoliciosporum curvatum. The communities are similar to those reported previously from Belgium, western Germany (Mosel valley), and Austria (Styria), apparently forming a characteristic association across central Europe (Fellhaneretum myrtillicolae SPIER & APTROOT), but are richer in species in the Black Forest than in any of the other areas studied. An identification key is provided to the species of this association in the Black Forest. Gyalectidium setiferum is new for central Europe, and Scoliciosporum curvatum is new to southern Germany.
Since these lichen communities appear to be confined to well-conserved forest and depend on favorable, warm-humid climatic conditions, their potential use as indicators of global climatic change is discussed.
Three new Geotomine species of the genus Paraethus Lis, 1994, have been discovered in the collection of the Muséum national d’Histoire Naturelle (Paris). Description of these species, Paraethus riegeri n. sp. and P. raunoi n. sp. from Africa and P. lisi n. sp. from Australia are given with illustration of male and female genitalia. The African species Aethus seyidiensis Jeannel, 1913, is transferred to Paraethus. New localities are given for this species. Additional generic characters are given for
Paraethus as well as a key to species of the genus.
The architectural features of the five Nasutitermes species occurring in a Neotropical floodplain (varzea) forest on llha de
Marchantaria in central Amazonia are described: external nest and runway architecture, nest volume, nest height above ground, nesting trees, degree of polycalism). These characteristics are used to build a tentative field key to the nest-building
termite species which should be tested for its usefulness for ecological studies of central Amazonian termites.
Orthotylus (Pachylops) neoriegeri sp. n. is described from Morocco (South Anti-Atlas). Colour dorsal habitus and illustrations of male and female genitalia are provided. The specimens were collected by beating Cytisus balansae (Fabaceae). Based on the pilosity, the male genitalia and the host-plant association, the new species is placed in the subgenus Pachylops Fieber, 1858.
It differs from the other species mainly by the brown coloration and the phallic sclerotized appendages of the male. Host-plant association within the subgenus Pachylops is briefy discussed.
Additional information on the distribution of eleven species of stilt bugs (Heteroptera, Berytidae) from the Afrotropical region is reported and discussed with respect to the major biomes of Africa. For some species, remarks on ecology, identifcation and taxonomy are included. New country records are indicated for Gampsoacantha pumilio, Gampsocoris africanus cornutus, Micrometacanthus trichoferus, Cametanthus madagascariensis, Metacanthus microphthalmus, M. mollis, M. nitidus,
Neostusakia picticornis and Yemma gracilis.
We provide a short history of the development of the Höwenegg quarry between 1985 and 1996, the rationale for continuing the excavations in 2003, and the progress made during the 2004-2006 campaigns. In the 2004 field season we completed our excavation at the western extent of the Main Höwenegg Trench, and retrieved a disturbed Miotragocerus skeleton in close proximity to the other two skeletons retrieved in 2003. We also opened a 5 m thick section in a trench 50 m north of the JÖRG and TOBIEN Quarry, and established the presence of vertebrate fossils and even richer deposits of fossil plant material. The 2005 and 2006 field seasons were dedicated to establishing and opening a new quarry adjacent to, and on the immediate western border of the Main Höwenegg Trench. The establishment of this new Western Quarry required extensive support from the Town of Immendingen for cutting down trees, removing a 1 m thick soil horizon with a
thick mat of roots, and undertaking trenching and bulldozing of disturbed sediments. The Western Quarry, approximately 100 m² in area, was extensively excavated by stratigraphic horizon, and initial correlations to the JÖRG and TOBIEN stratigraphic section made. We provide here statistics on the relative percentages of biotic elements collected, and their representation in our excavations. These analyses demonstrate that Unit 11, a marl where the Miotragocerus and Trionyx skeletons were excavated in 2003 and 2004, is both the richest and contains the most diverse biotic elements at the Höwenegg. These horizons were not excavated in 2004-2006 in the new Western Quarry, but will be in the 2007 field season.
A new species of Tingis (Hemiptera: Heteroptera: Tingidae) is described from the Spanish provinces of Valencia, Alicante, Murcia and Almería (southeastern Iberian Peninsula). Tingis (Tropidocheila) christianriegeri n. sp. is very similar to T. alberensis Péricart, 1979, and also seems to depend on plants of the genus Sideritis. However, it is easily distinguished by its dorsal setae, besides differences in distribution and, presumably, plant host species.
An inclusion in Miocene Dominican amber contained a well preserved velvety shore bug (Ochteridae), Riegerochterus baehri gen. nov., spec. nov., which is described and figured in this article. This is the first fossil representative of the family recorded from Cenozoic, as all previously described taxa are much older, e.g. from the Early Jurassic of England and the Late Jurassic-Early Cretaceous of China. It is distinguished from all extant genera of Ochteridae by several distinct characters that are shortly discussed. Figures and photos of representatives of fossil (Riegerochterus) and recent (Megochterus, Ochterus and Ocyochterus) genera are provided.
