Zettel, H. 2000. The Helotrephidae (Heteroptera) of Borneo. Entomol. Probl. 31(1): 1-22.

Thirteen new species of Helotrephidae are described from Borneo: Trephotomas kodadai sp.nov. (Sabah), Helotrephes ciampori sp.nov. (Sabah), Helotrephes mazzoldii sp.nov. (Kalimantan), Helotrephes recurvatus sp.nov. (Sabah, Sarawak), Hydrotrephes grabenwegeri sp.nov. (Sabah), Hydrotrephes hybridus sp.nov. (Sabah), Hydrotrephes intermixtus sp.nov. (Sabah), Hydrotrephes jani sp.nov. (Sabah), Hydrotrephes kalimantanensis sp.nov. Kalimantan), Hydrotrephes rarus sp.nov. (Sabah), Hydrotrephes sarawakensis sp.nov. (Sarawak), Hydrotrephes yangae sp.nov. (Sabah), and Distotrephes (Polhemotrephes) maculatus sp.nov. A new species group, the Hydrotrephes sarawakensis group, containing H. sarawakensis sp.nov. and H. kalimantanensis sp.nov. is defined. Trephotomas insulanus Zettel, 1997, and Helotrephes otoeis Nieser & Chen, 1999, are recorded from Kalimantan for the first time. Keys to the genera and to the species of Helotrephes and Hydrotrephes, which occur in Borneo, are presented. A check-list of Bornean Helotrephidae is provided. The female subgenital plate of Hydrotrephes corporaali (China, 1930) and the male genitalia of H. angulatus (China, 1930), both from Sumatra, are described for the first time.

New records of Ochthephilus brachypterus and Oxypoda tirolensis from the National Park of High Tatry in northern Slovakia are provided, both species being recorded for the first time from Slovakia.

Canale, A. & Raspi, A. 2000. Host location and oviposition behaviour in Opius concolor (Hymenoptera: Braconidae). Entomol. Probl. 31(1): 25-32.

Observations on host location and oviposition behaviour of the parasitoid Opius concolor Szépligeti in presence of Ceratitis capitata (Wiedemann) larvae as host were carried out. In addition, a S.E.M. study on the external morphology of the structures involved in each step of the behavioural sequence was performed. Results showed that the searching behaviour exhibited by O. concolor comprises a combination of search modes, as the insect responds to a hierarchy of different stimuli while locating a host. The antennae (in particular the last antennomeres) appear to be the most important structures involved in the host location process. Thus after a latency period (40-50 sec) the parasitoid walks rapidly, drumming the antennae alternately on the surface. After host location, when the parasitoid is upon the patch where the host is situated, the ovipositor plays an important role in host discrimination, often being used by females to probe a potential host before accepting or rejecting the host for oviposition. Stings resulting in successful oviposition generally last for 30- 40 sec, a time considerably longer than possible preceding attempts in which oviposition is aborted. A S.E.M. magnification of the last antennomeres showed the existence of different types of sensilla that may be directly involved in host location. Moreover, a morphological survey on the external feature of the tarsi revealed the presence of sensilla that could be involved in reception of vibrational signals. Finally, a morphological analysis of the ovipositor external structure is presented and discussed.

Csefalavay, R. & Zaťovičová, Z. 2000. Check list of Slovak species of the genus Hydroporus. Entomol. Probl. 31 (1): 33-34.

At present 29 species of the genus Hydroporus (Coleoptera: Dytiscidae) are recorded from Slovakia.

Schillhammer, H. 2000. A new genus and species of the subtribe Philonthina from Kashmir (Coleoptera: Staphylinidae). Entomol. Probl. 31(1): 35-37.

A new genus and species of the subtribe Philonthina is described: Gabriopalpus gen.nov. ecitolycoides sp.nov. (Kashmir). The male copulatory organ and some morphological details as well as the habitus are illustrated. The systematic position of the new genus is discussed.

Hernando, C. 2000. Description of a new Microtyphlus from the Catalonian Littoral Mountain Range ( NE Iberian Peninsula) (Coleoptera: Carabidae: Anillini). Entomol. Probl. 31(1): 39-40

A new species of endogeous ground-beetle from the Iberian peninsula, Microtyphlus bateti sp.nov., is described. The species has to be included in the M. zariquieyi Bolivar, 1916 species group, because of the presence of a denticle in the labium, the shape of the median lobe, and the inner piece of the internal sac of the aedeagus.

Jäch, M.A. & Díaz, J.A. 2000. Descriptions of eight new species of Hydraena (Coleoptera: Hydraenidae). Entomol. Probl. 31(1): 41-58.

(Hydraenopsis) cordiformis [China], H. (Hydraenopsis) cristatigena [New Guinea], H. (Hydraenopsis) cyclops [New Guinea], H. (Hydraenopsis) paucistriata [Vietnam], and H.
