Description of a new species and the karyotype of the cavernicolous millipede Pseudonannolene Silvestri and the karyotype of Pseudonannolene strinatti Mauriès (Diplopoda, Pseudonannolenida, Pseudonannolenidae)

Abstract

ABSTRACT. Pseudonannolene /ocaiensis, sp.n. is described from Brazil, Sao Paulo, ltirapina. The kalyotypes of P. /ocaiellSis, sp.n. and P. s/ril1alli Mauries, 1974 are also presented, both species are found in cave environments. P. locaiensis has 2n=20, XV and P. s/rinalli, 2n=16; it was not possible to observe the sex determination mechanism in the latter.

Two new species of Pseudonannolene Silvestri, 1895 from Brazilian iron ore caves (Spirostreptida: Pseudonannolenidae)

“…In relation to the distal region, the presence of two points in the solenomere and the shape of the internal branch in P. gogo, were similar to the species P. imbirensis (Fontanetti 1996a). In P. rolamossa, the proportion between the length and the width in the base of telopodite is similar to the species P. chaimowiczi, P. anapophysis (Fontanetti 1996a), P. tocaiensis (Fontanetti 1996b) and P. mesai (Fontanetti 2000), but the oblique shape of the internal branch distinguishes it from these species.…”

“…n. can be distinguished from other species of the genus by the following combination of characters. The pre-femoral process in the males resembles that of the species P. spelaea (Iniesta & Ferreira 2013a) P. tocaienses (Fontanetti 1996b), P. mesai (Fontanetti 2000), P.…”

“…strinatii (Mauries 1974) by the projection parallel to the femur and rounded aspect, while the widths and lengths of the processes are different. The darkened color of the prozonite resembles some species such as P. tocaienses (Fontanetti 1996b) and P. mesai (Fontanetti 2000), although P. anapophysis (Fontanetti 1996a) and P. chaimowiczi (Fontanetti 1996a) show a lighter prozonite and metazonite with a darkened color. Regarding the eyes, both species have ocelli numbers usual for the genus, between 20-43 ocelli.…”

The first troglobitic <i>Pseudonannolene</i> from Brazilian iron ore caves (Spirostreptida: Pseudonannolenidae)

“…According to Fontanetti (2002), another important taxonomic trait of the group is the prefemoral process in the first pair of legs of the males. Concerning this process, P. spelaea is similar to P. tocaienses (Fontanetti 1996b), P. mesai (Fontanetti 2000), P. chaimowiczi (Fontanetti 1996a), P. strinatii (Mauriès 1974) in presenting processes parallel to the coxa. Such a characteristic differs from P. anapophysis (Fontanetti 1996a), which does not present such a process.…”

New species of Pseudonannolene Silvestri, 1895 from Brazilian limestone caves with comments on the potential distribution of the genus in South America (Spirostreptida: Pseudonannolenidae)

“…In caves, the first Brazilian species described was P. strinatii Mauriès, 1974, found in the Gruta das Areias cave, São Paulo state (Mauriés 1974). Other species were subsequently described, mainly by Fontanetti (1996a;1996b) and Iniesta & Ferreira (2013b, 2013c.…”
