De kleine wrattenbijter Gampsocleis glabra herontdekt in Nederland (Orthoptera: Tettigoniidae) Naturalis
Berg, A. van der; Haveman, R.; Hornman, M..
Gampsocleis glabra rediscovered in the Netherlands (Orthoptera: Tettigoniidae) Until recently, Gampsocleis glabra was considered to be extinct in the Netherlands since 1987. In 1999, this species was found in large accounts at the military firing range Oldebroek in the province of Gelderland. Gampsocleis glabra seems to prefer open heath (Genisto-Callunetum danthonietosum) and grassland communities (Galia hercynici-Festucetum ovinae) with a low moss abundance. On the Oldebroekse Heide the vegetation is burnt periodically, with a cyclus of 8 years. It is remarkable that on the Lüneburger Heide (Niedersachsen, Germany) the vegetation is burnt on a large scale too. This is the only other site where G. glabra survived in northwestern Europe.

Chromosomal basis for a bilateral gynandromorph in Pycnogaster inermis (Rambur, 1838) (Orthoptera, Tettigoniidae) Naturalis
Barranco, P.; Cabrero, J.; Camacho, J.P.M.; Pascual, F..
Morphological and cytogenetic analyses of a spontaneous gynandromorph of Pycnogaster inermis, found in a natural population in the Spanish Sierra Nevada, have shown that the left side was male and the right side female, with almost perfect bilateral symmetry. Ventral valves of the ovipositor were very short, appearing as two spurs; dorsal valves were longer but still shorter than normal. The specimen had an apparently normal testis on the left side and a well-developed ovary on the right side. Cytogenetic analysis revealed the presence of 2n = 28 + X0 chromosomes in the testis and 2n = 28 + XX in the ovary, the same as standard males and females, respectively, of this species. This suggests that the gynandromorphism occurred at a very early developmental...
