Taxonomic importance of the prefemoral process of the first pair of legs in males of the genus Pseudonannolene (Diplopoda, Spirostreptida)
(2002-12-01)
The first pair of legs in males of some groups of diplopods is modified, having a large coxa and oral projecting prefemoral process; in the family Spirostreptidae (Spirostreptida) this structure has relevance on the genus ...
Cytogenetic studies in Diplopoda
(2002-09-01)
The Diplopoda have received little attention from cytogeneticists owing mostly to technical difficulties in obtaining mitotic chromosomes, restricting the studies to meiosis and eventual spermatogonial metaphases, which ...
High content of constitutive heterochromatin in two species of Pseudonannolene (Diplopoda)
(2005-12-01)
Due to the fact that a considerable amount of constitutive heterochromatin has been commonly found in millipedes, this paper presents the characterization of the chromosomal complement, through C-banding technique, of two ...
