Genus
Ribautiella
Brölemann, 1926
.
Type
species
Ribautiella zagnanadina
Brölemann, 1926
, described from
Benin
.
Diagnosis
23 tergites, which means that the tergal areas 2, 3, 6, 9, 12, 13, 14 and 15 (
fide
Domínguez Camacho, 2009
, fig. 4, page 108) are subdivided into two subtergites; first tergite small, tergites 3, 5-7, 9-11, 13-15, 17, 18 and 21 with paired, triangular posterior processes. In his
Keys to the Genera of
Symphyla
,
Edwards (1959)
mentions the presence of 24 tergites as a diagnostic feature for this genus. This higher number is due to a supposed subdivision of the first tergite. However, this characteristic is questionable since descriptions and illustrations are
not
satisfactory and this subdivision appears in different grades among the species. The present study using SEM suggests that it is probably an artefact of the mounts for light microscopy (
Fig. 11A, D
).
First pair of legs reduced either to hairy or spiny knobs or spots. This diagnostic character is also present in
Symphylella
. Accordingly, the combination of the characters 1 and 2 is the strongest diagnostic character set for
Ribautiella
.
Only both exterior parts of the tergites 2-21 completely sclerotized (
Fig. 11A, D
). This character is also present in other scolopendrellid genera, such as
Scolopendrellopsis
,
Geophilella, Parviapiciella
(
Domínguez Camacho 2009
) and probably
Remysymphyla
.
Terminal area of cerci small, with basis diagonal, pointing back- and inwards rather than transverse (
Fig. 11B, E
). Striae – if present – also diagonal rather than transverse, pointing back- and inwards (
Fig. 11F
).
