Mandibles of twenty species of short horned grasshoppers (Orthoptera: Caelifera) have variations among different species

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...

Grasshoppers of the Mascarene Islands: new species and new records (Orthoptera, Caelifera).

The grasshopper fauna of Mascarene Islands (Mauritius, Rodrigues and La Réunion), in South Western Indian ocean is examined. Numerous field surveys and examination of museum specimens recorded twenty species of Grasshoppers on the archipelago. Five of them are new records, including a new species: Odontomelus ancestrus n. sp. restricted to Round Island, a 2 km² islet North to Mauritius. Despite...

SYLVAIN HUGEL (2014) Grasshoppers of the Mascarene Islands: new species and new records (Orthoptera, Caelifera). Zootaxa, 3900 (3): 399-414.

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...
