The Gryllus genus represents one the most complex in the Orthoptera systematic, characterized by a set of cosmopolite and cryptic species, many of them already described. This study compared the songs emitted by Gryllus specimens collected on the UNESP campus in Rio Claro (SP) and the pars stridens morphology and morphometry, to use the results to recognize possible cryptic species and contribute to the discussion of speciation processes. Three groups of crickets were discriminated by differences in the pars stridens and calling songs, characterized by different rhythms, frequencies and note composition, that indicated the presence of three species in the location analyzed, that presented few morphological differences. It is suggested from the results that... |

The present study compares the metanotal gland through scanning electron microscopy in five species of Eidmanacris: E. corumbatai Garcia, 1998, E. alboannulata (Piza, 1960), E. dissimilis Desutter-Grandcolas, 1995, E. larvaeformis (Chopard, 1938) and Eidmanacris sp. The general external configuration of the gland was determined by the presence of two median projections with apical opening and a cluster of bristles just above these projections. Although there is a general pattern for this gland, each species has its own pattern, which can be defined mainly by the arrangement of the bristles and the position of the median projections. Our results suggest the taxonomical importance of these structures, which should be better analyzed when describing species... |
