Chromosomal characterization of Pseudonannolene strinatii (Spirostreptida, Pseudonannolenidae)
Campos, Kleber Agari;Fontanetti, Carmem S.;
Iheringia. Série Zoologia , 2004, DOI: 10.1590/S0073-47212004000100009
Abstract: the chromosomes of the cave millipede pseudonannolene strinatii mauriès, 1974 were investigated. the diploid chromosome number was found to be 2n=16, xx/xy; the c-banding technique revealed a large amount of heterochromatin while the silver staining technique (ag-nor) evidenced the presence of heteromorphism of the nors in some cells.

Description of a new species and the karyotype of the cavernicolous millipede Pseudonannolene Silvestri and the karyotype of Pseudonannolene strinatti Mauriès (Diplopoda, Pseudonannolenida, Pseudonannolenidae)
Fontanetti, Carmem Silvia;
Revista Brasileira de Zoologia , 1996, DOI: 10.1590/S0101-81751996000200012
Abstract: pseudonannolene tocaiensis, sp.n. is described from brazil, s?o paulo, itirapina. the karyotypes of p. tocaiensis, sp.n. and p. strinatti mauriès, 1974 are also presented, both species are found in cave environments. p. tocaiensis has 2n=20, xy and p. strinatti, 2n=16; it was not possible to observe the sex determination mechanism in the latter.
Microspines in the pylorus of Pseudonannolene tricolor and Rhinocricus padbergi (Arthropoda, Diplopoda)
Miyoshi, Akio R.;Gabriel, Vagner A.;Fantazzini, Evandro R.;Fontanetti, Carmem S.;
Iheringia. Série Zoologia , 2005, DOI: 10.1590/S0073-47212005000200008
Abstract: the aim of this paper is to report the morphology and distribution of microspines in diplopods pylorus, as these are important structures present along the alimentary tract of arthropods. the morphology of the internal surface of the pylorus of pseudonannolene tricolor brolemann, 1901 and rhinocricus padbergi verhoeff, 1938 was analyzed by sem. pseudonannolene tricolor presents two morphologically distinct pyloric regions: anterior and posterior. the first region is characterized by the presence of thin microspines that increase in number and size towards the posterior portion; the second region presents smaller and triangular-shaped microspines distributed throughout small plates. the pylorus of r. padbergi does not present differentiated regions; the anterior portion is characterized by microspines grouped in plates that decrease in number and increase in size towards the ileum.

Abstract: This paper presents 14 species of Oniscidea and four species of Diplopoda - among them a species new to science belonging to the genus Bulgardicus Strasser, 1966 - collected exclusively in parks of Bucharest.
Vertical distribution of Diplopoda populations from deciduous forests  [PDF]
Gava R.
Archives of Biological Sciences , 2004, DOI: 10.2298/abs0402059g
Abstract: The vertical distribution of Diplopoda populations from deciduous forests is analyzed. The observations were made in oak, beech, and alder forests situated on the southern slopes of the F g ra Mountains in the middle of the watershed of the Arge River (Danube basin).
Diplópoda depredador de tubérculos de batatinha
Boock, O. J.;Lordello, Luís Gonzaga E.;
Bragantia , 1952, DOI: 10.1590/S0006-87051952000400006
Abstract: in two independent irish potato experiments carried out at the lameira exp. sta. of the instituto agron?mico de campinas, in 1952, serious damage was observed in the tubers due to the attack of a diplopoda - pseudonannolenidae, pseudonannolene paulista br?lemann, 1902. one of these experiments was undertaken in order to test the varieties konsuragis and eigenheimer imported from sweden. amonium sulphate, cotton or ricinus meal were used as source of nitrogen at the rate of 80 kg of n per hectare. superphosphate at the rate of 120 kg of p2o5 and potassium sulphate at the rate of 60 kg of k2o were also used in this experiment. it has been observed that the number of affected tubers was greater in the konsuragis variety and also that the attack by diplópoda was more intensive in the plots where cotton or ricinus meal was used. in the other experiment the following varieties were tested, all them received from holland: bintje, eersteling, saskia, gineke, eigeriheimer, voran and alpha. only amonium sulphate was used as source of nitrogen, this element, p2o5, and k2o, having been added at the same rate as in the first experiment. the varieties bintje, eersteling and saskia had a great number of damaged tubers while alpha seemed to be much more resistent. the maximum temperature observed during the experiment varied from 21.3 to 30.2°c and the minimum temperature from 5.5 to 14.2°c. the amount of rainfall was very small, only 16 mm being registered during february to may. chemical analysis of the soil revealed that it was poor in mineral contents and had high acidity. the present observation confirms the findings of blunck, who established that when the soil is hot and dry, diplópoda feeds on potato tubers in order to get water. it has been suggested that the attack by the diplópoda here observed is of the same nature as that caused by the diplópoda cylindroiulus frisius verhoeff and c. teutonicus poc. observed in germany in tubers of irish potato.

Fontanetti, Carmem Silvia;
Revista Brasileira de Zoologia , 1990, DOI: 10.1590/S0101-81751990000400013
Abstract: the morphology of the testicles of some brazilian species of diplopoda is described. one type is scalariform, with two deferent ducts and the other consists of some single deferent duct. phyllogenetic considerations on the structure are made.
