Lauterer P. & Burckhardt D. 1997. Central and West European willow-feeding jumping plant-lice of the genus Cacopsylla (Hemiptera: Psylloidea). Entomol. Probl. 28 (2): 81-94.

Cacopsylla perrieri sp.nov. is described and illustrated from Southern France and differences to closely related species are discussed. Intraspecific variation in paramere morphology is described and illustrated for C. perrieri, C. saliceti and C. moscovita. A neotype is designated for Psylla salicis Ramírez Gómez, which is synonymised with C. saliceti. The occurrence of two colour races is reported for C. ambigua, and differences are discussed between C. intermedia and the closely related species C. abdominalis and C. ambigua. Based on the study of parts of the a holotype, Cacopsylla picta (Foerster , 1848) is recognised as senior synonym of Cacopsylla costalis (Flor, 1861). The 17 Central and West European Cacopsylla spp. associated with Salix are listed with synonyms, distributions and host plants. SEM pictures are provided of the parameres of 11 species of the saliceti group. top.gif



Vít S. & Hlaváč P. 1997. Euconnus (subg.Tetramelus) from Caucasus and Turkey (Coleoptera: Scydmaenidae). Entomol. Probl. 28 (2): 95-103.

Five new species of Euconnus subg. Tetramelus are described: E. abkhazicus and E. bulirschi, from the Georgian Republic in the Caucasus, and E. ayderinus, E. kaplidjun and E. lazin from the Eastern Black Sea area in Turkey. All species belong to the same species-group which is well characterised by features of the aedeagus. top.gif



Majzlan O. 1997. Barypeithes purkynei Fremuth, 1965, a species of weevil (Coleoptera, Curculionidae) endemic in Slovakia. Entomol. Probl. 28(2): 104.

The species Barypeithes purkynei is one of four endemic species of the genus Barypeithes living in Slovakia. It is found in the highest zones of the mountains (from 800 - 1300 m above sea level). Until now it was determined at two localities in the Vtáčnik and Malá Fatra Mts in central Slovakia. Maximal occurrence was recorded in summer months of July and August. top.gif



Hendrich L. 1997. A new species of cybister Curtis, from the Kakadu National Park in Northern Australia (Coleoptera: Dytiscidae). Entomol. Probl., 28 (2): 105-108.

Cybister weckerwerthi sp nov. is described from the Kakadu National park in the Northern Territories of Australia. The species is well characterized by its small size, the broad yellow banded elytra and pronotum and the testaceous scutellum which is unique in the Oriental and Australian Cybister species known so far. A key to the five Australian species of the genus is presented. Some details about its habitat are also included. top.gif



Shillhammer H. 1997. Turgiditarsus, a new name for Tumiditarsus Schillhammer with description of a new species (Coleoptera: Staphylinidae). Entomol. Probl. 28(2): 109-110.

Tumiditarsus Schillhammer, 1996 (nec Zajciw, 1961) is replaced by Turgiditarsus nom. nov. and a new species is described: Turgiditarsus kodadai (E. Malaysia: Sabah). top.gif



Jäch M. A. & Boukal D. S. 1997. The genus Hedyselmis Hinton (Coleoptera: Elmidae). Entomol. Probl., 28 (2): 111-116.

The genus Hedyselmis Hinton (Elmidae) is redescribed and its phylogenetical position is discussed. Hedyselmis gibbosus sp. nov. is described. top.gif



Zettel H. 1997. Notes on Helotrephidae (Insecta: Heteroptera) from Borneo, with descriptions of two new species of the genera Fischerotrephes and Trephotomas. Entomol. Probl., 28(2): 117-126.

Fischerotrephes maryatiae sp.nov. and Trephotomas insulanus sp.nov. (both from Sabah, Malaysia) are described as new. This represents the first record of the Southeast Asian genus Trephotomas Papánek, Štys & Tonner, 1988, from the Malay Archipelago. Idiotrephes chinai Lundblad, 1933, is newly recorded from Borneo; the identity of this species is discussed, and a lectotype is designated. New records of Distotrephes (Polhemotrephes) heveli Polhemus, 1990, and D. (P.) sarawakensis Zettel, 1995, are presented from Sabah. The male of D. heveli is described for the first time. Specimens of a possibly undescribed Distotrephes species from Sarawak are treated. The type locality of Fischerotrephes maryatiae sp.nov. in the Danum Valley is described in detail. top.gif



Olejníček J. & Kozánek M. 1997. Systenus slovaki sp. nov. (Diptera, Dolichopodidae) from Korea. Entomol. Probl. 28(2): 127-129.

Systenus slovaki sp. nov. is described from North Korea. The new species should be well distinguished from all the world known species of the genus by the shape of the arista and by the dark field in the wing. A key to Asian species of the genus is given as well as the checklist of world species. top.gif



Buck M., Menzel F. & Rudzinski H.-G. 1997. Necrophage Trauermücken (Diptera, Sciaridae): Ergebnisse aus Zuchtversuchen mit freilandexponierten Ködern nebst Anmerkungen zur Taxonomie. Entomol. Probl. 28(2): 131-139.

Necrophagous sciarid flies (Diptera, Sciaridae): results of rearing experiments with field-exposed baits including taxonomic remarks. Rearing experiments were conducted in the vicinity of Ulm (Germany) using baits and samples of decaying matter collected in the field. Thirteen types of substrates consisted of vertebrate, mollusc and insect carrion (9 types), rotten plant material (3 types) and fungi (1 type). 3869 adult Sciaridae belonging to nine species in four genera emerged from these substrates. Corynoptera blanda (Winnertz) and Lycoriella castanescens (Lengersdorf) dominated in terms of numbers of colonized samples. L. cellaris (Lengersdorf) yielded the highest number of specimens. Most recorded species are eurytopic saprophages which are not specifically related to carrion. The larvae probably feed on fungal mycelia and preferably colonize carrion in an advanced stage of decay. Females of Corynoptera blanda and Lycoriella cellaris are described for the first time and detailed redescriptions of the males are given. top.gif



Neto L. & Pintureau B. 1997. Review of the genus Mirufens Girault (Hym.: Trichogrammatidae). Entomol. Probl. 28(2): 141-148.

The genus Mirufens comprises 14 species which were listed. Its division in two sub-genera, poorly limited, was reconsidered. A modification of this division and a new sub-genus, Pseudotrachocera, were proposed. The study of new material led to the recognition and description of the male of one species (only known by females). Characteristics of two new species from Asia were also supplied; but these two species, named M. sp.1 and M. sp. 2, were not formally described because of limited material. A synthesis of data concerning the geographical distribution (essentially in Asia) and hosts (Homoptera) of the genus Mirufens was carried out. Finally, a key for both females and males of all species was elaborated. top.gif



Barták M. 1997. Rhamphomyia (Diptera, Empididae) from Korea, with descriptions of new species. Entomol. Probl. 28(2): 149-154.

The first information about the genus Rhamphomyia from Korea is given. Four species are described as new: Rhamphomyia koreana sp. nov., R. kozaneki sp. nov., R. ryongaksanensis sp. nov., and R. slovaki sp. nov. Five species are recorded from this country for the first time: R. flavipes Matsumura, R. fulvirostris Saigusa, R. grammoptera Frey, R. lucidula Zetterstedt, and R. setulosa Saigusa. top.gif



Brown B.V. 1997. The undescribed male of Beckerina sinefurca Borgmeier and the recognition of Neotropical Beckerina (Diptera: Phoridae). Entomol. Probl. 28(2): 155-158.

The previously unknown, and structurally unusual male of Beckerina sinefurca Borgmeier is described. Unlike all other known Beckerina species, the male of B. sinefurca has flagellomere 1 greatly elongate and apically narrowed. This characteristic will not allow male specimens of this species to be identified in the latest key to world phorid genera. Many other Neotropical Beckerina similarly will not key properly but can by recognized using the diagnosis given here. top.gif
