Many species of liverworts (<i>Hepaticae</i>) are morphologically plastic to such an extent that their proper recognition may cause difficulties even for a specialist. Central European species of the genus <i>Pellia</i> are notorious in this respect. Searching for less malleable diagnostic characters (than morphological and/or anatomical ones) we showed recently that the electrophoretic phenotypes (obtained by means of separation of enzyme proteins on starch gels) can be used for reliable identification of <i>Pellia</i> species with much reliability. During the last 20 years we performed electrophoretic identification of over 500 (exactly 541) colonies and discovered that at least two of the "classic" species of the genus <i>Pellia</i> are in fact species complexes comprising taxa having the character of sibling species. In this paper we have mapped all stations of electrophoretically identified <i>Pellia</i> species, including the sibling species mentioned; marked differences in their geographical distributions are discussed. Our work clearly shows that using more natural taxa (i.e.genetically defined sibling species instead of weakly characterised species complexes) in bryogeography, one can obtain meaningful results even in a geographically restricted area as, for instance in Poland.

Formerly Cnemidophorus was thought to be the most speciose genus of Teiidae. This genus comprised four morphological groups that were later defined as four different genera, Ameivula, Aurivela, Cnemidophorus and Contomastix. The last appears as paraphyletic in a recent phylogenetic reconstruction based on morphology, but monophyletic in a reconstruction using molecular characters. Six species are allocated to Contomastix. One of them, C. lacertoides, having an extensive and disjunct geographic distribution in Argentina, Uruguay and Brazil. Preliminary analyses revealed morphological differences among its populations, suggesting that it is actually a complex of species. Here, we describe a new species corresponding to the Argentinian populations hitherto regarded as C. lacertoides, by integrating morphological and molecular evidence. Furthermore, we demonstrate that the presence of notched proximal margin of the tongue is a character that defines the genus Contomastix.

AbstractThe aim of this review is to summarize the literature knowledge about how abiotic environmental factors and biotic interactions affect the sequentially overlapping longitudinal distribution of Central European species of the net-spinning freshwater caddisfly larvae of the genus Hydropsyche (Trichoptera: Hydropsychidae). In this relation, several physical and chemical parameters of water are discussed, as well as different species-specific traits, behavioural aspects and the interaction of coexisting species. Longitudinal gradients of river networks, especially annual temperature range, flow velocity and the particle size of suspended food material play a crucial role in forming the downstream succession of characteristic species, while increased levels of organic pollution, nutrients, salinity and heavy metals facilitates the presence of more tolerant ones. Several species-specific traits, such as respiration range, net-building frequency, head capsule size or optimal net-building velocity correlate with the position of a given species in the sequence. Coexistence of species with similar ecological demands in the overlapping zones of distribution is facilitated by differences in feeding and net-building habits, microhabitat preferences and staggering life cycles, but complicated at the same time by means of inter- and intraspecific territorial behaviour, such as fighting for the ownership of larval retreats or the practice of stridulation.

The subgenus Sidonis Mulsant, 1850 is elevated to generic status and two new species from Brazil are described and illustrated: Sidonis bira sp. nov. and Sidonis biguttata sp. nov. New geographic distribution records are provided. In addition, lectotypes of Sidonis consanguinea (Mulsant, 1850) and S. guttata (Sicard, 1912) are designated. Illustrations of diagnostic characters from five of six species of the genus, comments on the differences from similar species and a key to all recognized taxa are included.

Incertae Sedis

The genus Macroderes Westwood, 1842 (Scarabaeidae: Scarabaeinae, tribe incertae sedis) is practically endemic to South Africa with only one species that is found little north in southern Namibia. The ranges of the species are limited to the winter-fall and bimodal biomes of South Africa comprising the regions of Richtersveld as extreme points of its northerly distribution, and extending to the south through Namaqualand to Cape Agulhas. The taxonomy of the genus is revised. Fourteen valid species are recognised and three others are of doubtful validity. Seven new species are described, these are: M. cederbergensis Abdalla & Deschodt, new species, M. tortuosus Abdalla & Scholtz, new species, M. gifboomi Abdalla & Scholtz, new species, M. leipoldti Abdalla & Deschodt, new species, M. oreatus Abdalla & Deschodt, new species, M. porselinus Abdalla, new species, and M. soleiana Abdalla & Deschodt, new species. Macroderes nitidus Harold, 1877 is redescribed and its lectotype is designated. The diagnostic characters as well as an updated geographic distribution of each species are summarised. An updated key of the genus, photographs of habitus, sclerites of internal sac, pronotum, pronotal punctures and elytra also are provided.

Eristalis tecta sp. n. is described, based on material from the Macedonian Museum of Natural History (Skopje, Macedonia, former Republic of Yugoslavia). This species is closely related to E. interrupta (Poda, 1761). Diagnostic characters of the species, together with figures of the male terminalia, are given. A checklist ofthe Eristalis species known from the Balkan Peninsula is presented.

The taxonomy of the American Onthophagus Latreille, 1802 included in the “hirculus” group is revised, and a study of their morphology allows for the delineation of five species-complexes. Herein, we provide a diagnosis of the “hirculus” group, an illustrated key to the complexes, along with a descriptive overview of their taxonomy and geographic distribution. Onthophagus hirculus Mannerheim, 1829 is considered to be a junior synonym of O. hircus Billberg, 1815, which is here demonstrated to be a valid species name. Thus, the “hirculus” group is here renamed the “hircus” group. Furthermore, a general scheme of the genital organs of American Onthophagus is provided, including names of different anatomical parts and a brief discussion on the need for nomenclatural stability for the genitalia of scarab beetles.

First Time

In the tenthredinid hymenopteran genus Empria, the European species with a paired whitish patch on tergum 1 are considered tentatively as a species-group termed the E. hungarica group. The type materials of Empria pumila (Konow), E. pumiloides Lindqvist and E. tricornis Lindqvist were examined. The lectotype and paralectotypes of E. pumila are designated, and new diagnostic characters for E. pumila and E. pumiloides are given. A key for the Northern European species of the E. hungarica group is compiled. The results of a comparison of the phenology and some metrical characters of the adults of E. pumila and E. pumiloides are presented in the form of diagrams. E. pumiloides is recorded for the first time from Russia and Germany. The records of E. hungarica from Estonia (Saaremaa) are reported as the northernmost for that species. All available distributional records of Empria hungarica in the Palaearctic are given in the text, and those localized reliably are also mapped.
