New data are presented for Neotropical Phalangopsidae (Orthoptera, Grylloidea). Four new species are described, Luzara brevipennis Desutter-Grandcolas, n. sp., Miogryllodes hebardi Desutter-Grandcolas, n. sp., Aclella brevipennis Desutter-Grandcolas, n. sp. and Aclella nova Desutter-Grandcolas, n. sp. Nine new recombinations are proposed: Lerneca digrediens (Otte, 2006) n. comb. (Amphiacusta), ...

Amblyrhethus Kirby, 1906 is a genus of arboreal, undergrowth, and shrub crickets comprising, at present, seven species: one from Panama, Peru, two Colombia, Brazil, with an unprecise locality. These are seldom found in regular active collecting night, although males produce rather loud calling song. Unfortunately, their songs have never been recorded, there no ecological information for this so...

The genus Laranda has six described species and is confined to South and Southeast of Brazil. We describe a new species and discuss the biology and distribution of the genus. The new species can be distinguished from its known congeners by the following characteristics: absence of yellow spots on pronotum and base of posterior tibiae; female copulatory papilla: sclerotization in dorsal view for...

Crickets produce stridulated sounds by rubbing their forewings together. The calling song of the cricket species Eneoptera guyanensis Chopard, 1931 alternates two song sections, at low and high dominant frequencies, corresponding to two distinct sections of the stridulatory file. In the present study we address the complex acoustic behavior of E. guyanensis by integrating information on the pec...

Stable isotope analysis (SIA) is an important tool for investigation of animal dietary habits for determination of feeding niche. Ideally, fresh samples should be used for isotopic analysis, but logistics frequently demands preservation of organisms for analysis at a later time. The goal of this study was to establish the best methodology for preserving forest litter-dwelling crickets for later...
