Genus Ribautiella Brölemann, 1926 View in CoL .
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 View Fig ).
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 View Fig ). 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 View Fig ). Striae – if present – also diagonal rather than transverse, pointing back- and inwards ( Fig. 11F View Fig ).
