Assing, V. 2003. A review of the Himalayan species of Amaurodera (Coleoptera: Staphylinidae: Aleocharinae). Entomol. Probl. 33(1-2): 5-20.

The types and additional material of the Himalayan representatives of Amaurodera Fauvel are revised. Twelve species are recognized, (re-)described, and illustrated, among them five species new to science: Amaurodera cameroni sp.nov., A. verrucosa sp.nov., A. coriacea sp.nov., A. fulgens sp.nov., and A. granata sp.nov.

Tierno De Figueroa, J.M. & Derka, T. 2003. Egg description of Isoptena serricornis (Plecoptera: Chloroperlidae). Entomol. Probl. 33(1-2): 55-57.

The egg of Isoptena serricornis (Pictet, 1841) is described and illustrated. Data on morphology (general oval shape, circular in cross-section, absence of chorionic cells), colour (yellow), and size (approximately 3.3 x 106 µm3 volume) of the egg and presence and size of the egg collar (approximately 70 µm diameter, 20 µm high) are supported. The maximum quantity of eggs found per dissected female is less than 50, which shows a low fecundity for this species.

Shaverdo, H.V. 2003. A new species of Hydroporus from Chukotka, Northern Far East of Russia (Coleoptera: Dytiscidae). Entomol. Probl. 33(1-2): 59-62.

Hydroporus amguemensis sp.nov. is described from the lower reaches of Amguema River, Chukotskiy Autonomous Okrug of Russia. The species could not be placed in any existing species-group of Hydroporus Clairville, 1806. Therefore, a new species-group is recognized, the Hydroporus amguemensis-group (monobasic, including only H. amguemensis, sp.nov.) based on the following character combination: body outline in dorsal aspect discontinuous at pronotal elytral conjunction, pronotum and elytron without microreticulation, metacoxal processes with posterior margins conjointly slightly broadly angulate, anterior face of protibia with one row of punctures, broad form of the median lobe of the aedeagus with U-shaped notch at its apex.

Assing, V. 2003. A revision of Othiini. XIII. Horizontal and vertical distribution of Othius, new species, and additional records (Coleoptera: Staphylinidae: Staphylininae). Entomol. Probl. 33(1-2): 69-88.

The current state of knowledge regarding the distribution of the Palaearctic genus Othius Stephens is summarized and mapped. The vertical distribution patterns of Western and Eastern Palaearctic Othius species are analysed and compared in relation to the extension of the respective horizontal ranges. Seven Eastern Palaearctic species of Othius Stephens are described, illustrated, and distinguished from closely related congeners: O. hirthei sp.nov. (central Nepal), O. caecitubus sp.nov. (central Nepal), O. resultus sp.nov. (central Nepal), O. schuelkei sp.nov. (China: Daba Shan), O. longilabris sp.nov. (China: Daba Shan), O. schillhammeri sp.nov. (Guizhou), and O. sericipennis sp.nov. (China: Sichuan). Additional records are presented for 28 species of Othius and 3 species of Atrecus Jacquelin Du Val. The distributions of Othius lapidicola Märkel & Kiesenwetter, O. crassus Motschulsky, O. subuliformis Stephens, O. brevipennis Kraatz, and O. wunderlei Assing are mapped. Based on biogeographic evidence, interspecific competition is hypothesized to be an important factor limiting the ranges of these and possibly also other species of the genus.

Pelletier, J. & Borovec, R. 2003. A new species of Trichocaulus from Tunisia (Coleoptera: Curculionidae s. l.). Entomol. Probl. 33(1-2): 89-91.

A new species of Trichocaulus, T. brevipilis is described from Tunisia. The new species is closely related to T. longipilis Fairmaire, 1877 but can easily be distinguished from the latter by the short setae bent on the integument of elytrae instead of very long erected hairs. In addition, in the only known females, the form of spermatheca is clearly different, S-shaped in T. brevipilis and just folded in T. longipilis.

Canale, A., Conti, B. Petacchi, R. & Rizzi, I. 2003. Thysanoptera collected in an onlive-growing area o the northern Tuscany (Italy). Entomol. Probl. 33(1-2): 105-110.

In the framework of research aiming to quantify the presence and damage induced by Liothrips oleae (Costa) (Thysanoptera, Phlaeothripidae) in an olive-growing area of northern Tuscany (Italy), a sampling methodology was found to be effective for monitoring both the phytophagous and other different Thysanoptera species. Results of samplings showed the presence of 16 species, belonging to 3 of the main families of the order. Among these, Bacillothrips longipes (Reuter) is reported for the first time in central-northern Italy and Karnyothrips flavipes (Jones), already known to be present in Sardinia, is now reported on the Italian mainland. The greatest number of Thysanoptera was observed in sampling performed at the beginning of June. At this date, the greatest number of floricolous species was observed, because this period corresponds to the phenologic stage of olive tree flowering. The number of L. oleae specimens captured in the olive-groves was fairly small during early April and early June samplings, but greater in the late April and early August samplings. Their abundant presence in the late April sampling could be due to the numerous specimens of the overwintering generation.

Assing, V. 2003. A revision of the Western Palaearctic species of Diochus (Coleoptera: Staphylinidae: Staphylininae: Diochini). Entomol. Probl. 33(1-2): 111-117.

Four species are recognized, (re–)described, and illustrated: Diochus staudingeri Kraatz, 1869, D. libanoticus Fagel, 1966, D. hatayus sp.nov., and D. sulcatus sp.nov. The distributions of the species are mapped and a diagnostic key to the species is provided.

Vršanský, P. 2003. Unique assemblage of Dictyoptera (Insecta – Blattaria, Mantodea, Isoptera) from the Lower Cretaceous of Bon Tsagaan Nuur in Mongolia. Entomol. Probl. 33(1-2): 119-151.

The Dictyoptera fauna of Lower Cretaceous of Bon Tsagaan Nuur – one of the richest fossil insect sites in Mongolia and one of the most diverse in the world – is described. More than 600 specimens (including 60 complete fossils) are studied, comprising 20 species of roaches, one mantid and one termite. 19 roach and one termite species are new.
Environment interpretation is proposed for the major Bon Tsagan beds. The complicated stratigraphy of the site, with 17 different beds allows one to assess biocenotic changes through the time and to identify the probable climatic maximum. There is considerable similarity of the Barremian species in the Bon Tsagaan and Berriasian – Valanginian of Baissa in Transbaikalian Siberia, where the assemblages existed under different climatic conditions and at least 10 million years apart. Sibling (fixed sensu Vršanský (2000)) species differ only slightly in size and wing variation, therefore it is possible that species from Baissa represent direct ancestors of those in Bon Tsagan. The supposedly ancestral species from Baissa (from “warm” layers) are generally smaller then their Bon Tsagan counterparts. This might indicate a generally more humid climate at Baissa, since the composition of entire entomofauna clearly indicates that the Bon Tsagaan climate was warmer than that of Baissa. Both sites contain Dictyoptera of virtually the same niches, but in different proportions. Bon Tsagaan Nuur, as a warmer site, contains more archaic elements in spite of its younger age. Mantids as a progressive element occupied the warmer cenoses soon after their evolvement, where other advanced roach lineages are absent or very rare yet. The layer best correlated with Baissa (with “warm” and dry cenoses) is 45/19. The 23/22 fauna represent exclusively Jurassic forms, advanced groups are missing, thus making possible the older age of this layer. All other layers appear Barremian.
Due to the warm condition of the palaeolake, the dominant families of the assemblage are represented by Mesozoic elements of the Blattulidae and Caloblattinidae. Bon Tsagaan is the latest record of roaches with long ovipositor. Early Mesozoic Mesoblattinidae (= Blattidae) (Mesoblattininae) are common, extant Blattellidae are absent.
The perfect preservation state of the material allows one to appreciate some new morphological and microstructural characters of fossil cockroaches. The external ovipositor structure of Blattulidae supports the hypothesis of the relationship of Polyphagoidea and Umenocoleoidea. The within-species variability shows that the coloration pattern characteristic for early mantids may be rarely present in roaches.
Coprolites composed of purely roach fragments indicate the presence of a vertebrate species (possibly a bird) specialised in feeding exclusively on Blattaria at least during some period.
