Grasshoppers (Orthoptera Acridoidea) from the Lake Baringo area of Kenya

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...

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...

Studies in Guatemalan Caelifera: New grasshoppers and monkey grasshoppers (Orthoptera: Caelifera: Acridoidea & Eumastacoidea) and an updated checklist.

We describe six species of Acridomorpha, Orthoptera from Guatemala: Paralethus rowelli n. sp., Paralethus cerezoi n. sp., Episactus schusteri n. sp. (Episactidae: Episactinae), Pararhicnoderma eniocanoi n. sp. (Romaleidae: Bactrophorinae), Tela neumanni n. sp. and Leioscapheus faustinoi n. sp.

Immersion Tolerance in Rangeland Grasshoppers (Orthoptera: Acrididae)

New and little-known pygmy grasshoppers (Orthoptera: Tetrigidae) from Thailand.

An annotated list of 39 species in 25 genera and seven subfamilies of the pygmy grasshoppers (Orthoptera: Tetrididae) from Thailand is given; from these 18 species are recorded from this country for the first time. Five new species are described: Cotysoides gaponi sp. nov. (subfamily Metrodorinae), Eucriotettix anisyutkini sp. nov., Gavialidium bufocrocodil sp. nov., Scelimena bellula sp. nov. ...
