Sex chromosome diversity in Armenian toad grasshoppers (Orthoptera, Acridoidea, Pamphagidae)

Although previous cytogenetic analysis of Pamphagidae grasshoppers pointed to considerable karyotype uniformity among most of the species in the family, our study of species from Armenia has discovered other, previously unknown karyotypes, differing from the standard for Pamphagidae mainly in having unusual sets of sex chromosomes. Asiotmethis turritus (Fischer von Waldheim, 1833), Paranocaracr...

The Cytology of Tasmanian Short-Horned Grasshoppers ( Orthoptera: Acridoidea)

Mainly because of their large size, and general suitability for cytological study the chromosomes of the short-horned grasshoppers (superfamily Acridoidea) have been the subject of wide research. In the largest and most widely studied family, the Acrididae, early workers (McClung, 1905; Davis, 1908) reported the male number as being uniformly twentythree rod-shaped chromosomes, but Granata (191...

Two new species of the genus Eotmethis (Orthoptera, Acridoidea, Pamphagidae) from China.

Two new species of the genus Eotmethis Bey-Bienko, 1948, namely Eotmethis xiai sp. nov., and Eotmethis platyverticus sp. nov. from the Ningxia Hui Autonomous Region and Gansu province are described in this paper. The new species Eotmethis xiai sp. nov. is allied to E. recipennis Xi & Zheng, 1986, but differs from latter by the vertical diameter of eye about 1.2 times as long as horizontal diame...

Origin and Evolution of the Neo-Sex Chromosomes in Pamphagidae Grasshoppers through Chromosome Fusion and Following Heteromorphization

In most phylogenetic lineages, the evolution of sex chromosomes is accompanied by their heteromorphization and degradation of one of them. The neo-sex chromosomes are useful model for studying early stages of these processes. Recently two lineages of the neo-sex chromosomes on different stages of heteromorphization was discovered in Pamphagidae family. The neo-sex chromosome heteromorphization ...
