A new Brazilian species of the cricket genus Megalogryllus Chopard (Orthoptera: Gryllidae) Neotropical Entomology
Mesa,Alejo; García-Novo,Paula.
Megalogryllus clamosus a new species of cricket from the São Paulo State (Brazil) is described. Photographs of the holotype (male) and of the paratype (female) are provided, as well as a drawing of the structure of the right tegmen of the male and of the phallic sclerite structure. Photographs of the pars stridens teeth and sonogram of the male calling song are also provided.

Mesa,Alejo; Zefa,Edison.
Adelosgryllus rubricephalus, a new genus and species of phalangopsid cricket are described. Illustrations of male and female specimens as well as descriptions of phallic sclerites, chromosomes and geographical known distribution are furnished. A discussion on the species taxonomic status of this cricket within the family is also included.

Cytogenetics of six Brazilian species of Psocoptera Braz. J. Genet.
Zefa,Edison; Fontanetti,Carmem Silvia; Mesa,Alejo.
The karyotypes of the following six species of Brazilian Psocoptera are reported: Caecillius sp. (Caecillidae), Triplocania ? caudata New (Ptiloneuridae), Brachinodiscus cf. lepidus (Banks) (Psocidae), Psococerastis interrupta New (Psocidae), Ptycta nr reticulata New (Psocidae) and Trichadenotecnum sinuatum New (Psocidae). All of them had males with 2n = 17 and an XO sex determining mechanism.

Cytogenetics studies in Brazilian species of Pseudophyllinae (Orthoptera: Tettigoniidae): 2n(♂)=35 and fn=35 the probable basic and ancestral karyotype of the family tettigoniidae Neotropical Entomology
Ferreira,Amilton; Mesa,Alejo.
The karyotypes of five species of Brazilian Pseudophyllinae belonging to four tribes were here studied. The data available in the literature altogether with those obtained with species in here studied allowed us to infer that 2n(♂)=35 is the highest chromosome number found in the family Tettigoniidae and that it is present in species belonging to Pseudophyllinae, Zaprochilinae and in one species of Tettigoniinae. In spite of that all five species exhibit secondary karyotypes arisen surely by a mechanism of chromosomal rearrangement of centric fusion, tandem fusion and centric inversion types from those with 2n(♂)=35 and FN=35, they share some common traits. The X chromosome is submetacentric (FN=36), heteropicnotic during the first prophase, the largest of...

Cytogenetics studies in thirteen Brazilian species of Phaneropterinae (Orthoptera: Tettigonioidea: Tettigoniidae): main evolutive trends based on their karyological traits Neotropical Entomology
Ferreira,Amilton; Mesa,Alejo.
The thirteen species of Phaneropterinae here studied can be arranged in four different groups according to their basic karyological traits. All of them share the same kind of chromosomal sex determining mechanism with X0(male) and XX(female). The X chromosome differs among species and always appears heteropycnotic during prophase I, it is the largest in the set and segregates precociously during anaphase I. Among the species, the karyotypes varies in fundamental number between 31 to 21. The meaning of these significant changes in the karyotypes in relation to the phylogeny within some large taxonomic group of species is discussed.

Morphological characters and karyology of Miogryllus piracicabensis Piza (Orthoptera: Gryllidae) Neotropical Entomology
Mesa,Alejo; García-Novo,Paula; Roat,Thaisa; Portugal,Cauré.
The genus Miogryllus includes a considerable number of species, most of them still undescribed. From those already described, the amount of afforded details on morphology is not always enough to recognize the species, missing information on phallic and pars stridens structures as well as karyology. The present paper aims to improve these information, on the species M. piracicabensis.
