Die Symphyta der Äthiopischen Region. Neue Gattungen und Arten aus der Verwandtschaft
der Neacidiophora-und Netroceros-Gruppe (Hymenoptera: Symphyta:
Tenthredinidae: Allantinae). Entomol. Probl. 29 (1): 1-17.
As a result of the revision of the Afrotropical sawfly genera Neacidiophora
Enslin and Netroceros
Konow some new genera and species
are described and new combinations proposed: Pseudoneacidiophora
bicolor gen. nov. et sp. nov. and P. pleuritica (
Forsius) comb. nov.; Mucheana mandibularis gen. nov. et sp. nov. and Paranetroceros
mirabilis (Forsius) comb. nov. Netroceros
luteiventris Pasteels is considered a subspecies
of Netroceros rufiventris Konow
(N. rufiventris luteiventris Pasteels
stat. nov.). The male of N. rufiventris luteiventris
Pasteels and the female of Pseudoneacidiophora pleuritica
(Forsius) are described for the first time. All
species are illustrated, their distribution and relationships are discussed.

Two new mesostigmatic mites (Acarina; Proctolaelaps, Hypoaspis) associated
with erotylid and melolonthine beetles (Coleoptera: Erotylidae, Scarabaeidae) from Slovakia.
Entomol. Probl. 29 (1): 19-22.
Two new mesostigmatic mites (Acarina: Mesostigmata) were described. Proctolaelaps
slovacus sp. nov. (Ameroseiidae) has been described on the basis of collections from the
subcorticolous mycophilous erotylid beetles (Tritoma bipustulata
Fbr. and Triplax aenea
Shall.) and Hypoaspis (Hypoaspis) rhizotrogi
sp. nov. (Hypoaspididae) from the phytophagous melolonthine beetles (Rhizotrogus aequinoctialis
Hrbst., Scarabaeidae), both species from Slovakia.

Sebasthetops omaliniformis gen. et sp. nov. from South Africa
(Coleoptera: Elmidae). Entomol. Probl. 29 (1): 23-25.
Sebasthetops omaliniformis gen. et sp. nov. (Hydraenidae) is described from South Africa
(Cape Province). The new genus belongs to Prosthetopinae.
Mazur M. 1998.
Systematik und geographische Verbreitung der Otiorhynchus perdix-Gruppe (Coleoptera:
Curculionidae). Entomol. Probl. 29 (1): 27-68.
In the Otiorhynchus perdix group thirteen species, three subspecies and seven
varietes have been previously described. Among these only O.
perdix (Olivier, 1807), O. cephalonicus
Pic, 1902, O. adonis
Apfelbeck, 1906, O. valonensis
Apfelbeck, 1918 and O. conjungens
Apfelbeck, 1918 are distinct species. For
Otiorhynchus perdix the following synonymies are established: O. perdix ssp.
thalassinus
Apfelbeck, 1905; Otiorhynchus perdix
ssp. hypsobius Apfelbeck, 1905;
O. sturanyi
Apfelbeck, 1905; O. brachyscelis
Apfelbeck, 1911; O. brachyscelis var.
cetinjensis Apfelbeck, 1911; O.
squamiperdix Reitter, 1913; O. perdix
var. brutius
Reitter, 1913; O. dorotkanus
Reitter, 1913; O. striginurus
Reitter, 1913; O. thalassinus ab.
ascendens
Apfelbeck, 1918c; O. thalassinus ssp.
kiorensis
Apfelbeck, 1918b; O. perdix var.
excelsior
Apfelbeck, 1919; O. perdix var.
eugubinus
Solari, 1932; O. thalassinus var.
sanctus
Solari, 1932. Furthermore, it has been stated that:
1). O. perdix var. carpathorum Csiki,
1913 is a parthenogenic form of O. adonis; 2). O.
prokletiensis Apfelbeck, 1918 and O.
dukatiensis
Apfelbeck, 1919 do not differ specifically from
O. valonensis; 3). O. vodenensis Formanek,
1922 is a synonym of O. conjungens. Otiorhynchus perdix has been split in
two morphotypes (A and B). Their ranges and possible migration routes (the trans-Adriatic,
east-Alpine, Carpathian and several secondary paths) are characterised. Differences in the
distribution of the parthenogenic and bisexual forms of Otiorhynchus perdix and O.
adonis have been pointed out. The area of the "perdix" group has been defined
as circum-Pannonian with the dispersion centre in the South-West of the Balkan Peninsula.
Rozkošný R. & Kovac D. 1998.
Four new Oriental species of Ptecticus, with taxonomic and biological notes on some other
species (Diptera: Strationmyidae). Entomol. Probl. 29 (1): 69-77.
Ptecticus bifidus sp. nov. from Singapore, P. bilobatus sp. nov. from East Malaysia
(Sabah), P. siamensis sp. nov. from Thailand and P. subaustralis sp.
nov. from West and East Malaysia are described, illustrated and
their relationships are briefly discussed. A female of P. proximus
Rozkosny & Kovac is characterized for the first
time and two extreme colour forms of P. tricolor
V.D.Wulp are recorded from Thailand.
Bezděk J. & Bezděk A. 1998.
Cassida bergeali Bordy, 1995 (Coleoptera,
Chrysomelidae) - first record for Slovakia. Entomol. Probl. 29 (1): 18.
Based on material collected in Štúrovo, Cassida bergeali is recorded
from the territory of Slovakia for the first time. The characters
distinguishing Cassida bergeali from the closely related
species Cassida vibex L., 1767 are briefly mentioned.
Hlaváč P. 1998. New records of
Olisthaerinale (Coleoptera: Staphylinidae) from Slovakia. Entomol. Probl. 29 (1): 26.
The new records as well as all old records of Olistaerinae from Slovakia are
mentioned. Olisthaerus megacephalus Zetterstedt,
1828 is recorded for the first time in Slovakia.
