Seasonal Occurrence of Different Grasshoppers Species (Orthoptera: Acridoidea) in Uruguay

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. (Acrididae: Proctolabinae). four genera and five species are recorded for Guatemala and, at the same t...

DNA Barcoding and Species Boundary Delimitation of Selected Species of Chinese Acridoidea (Orthoptera: Caelifera)

We tested the performance of DNA barcoding in Acridoidea and attempted to solve species boundary delimitation problems in selected groups using COI barcodes. Three analysis methods were applied to reconstruct the phylogeny. K2P distances were used to assess the overlap range between intraspecific variation and interspecific divergence. "Best match (BM)", "best close match (BCM)", "all species b...
