Figs 52–53
Diagnosis
Differs from other species of
Raduliverpa
by having the limbus only very shallowly lobed, and the metaplical spinelike process (
msp
) very strongly curved, almost like a pig-tail, as opposed to the serrated limbus and much less curving
msp
seen in other species, see

Etymology
After Donatella Foddai, Italian myriapodologist, former resident of ‘Hotel Dolichoiulus’.

A
. Right telopodite, posterior view.
B
. Left telopodite, subanterior view.
C
. Right telopodite, disto-mesal-basal view.
D
. Close-up of right solenomere tip (also with part of post-torsal spine) to show the genuscharacteristic striation.

PTS
=post-torsal spine;
SLM
= solenomere;
TL
=torsotope lobe;
TM
= telomere;
tlm
= telomere lamellae;
TT
=torsotope. Scale bars: A–C, E =0.1 mm; D =0.02 mm.
MANDIBULAR STIPES. Ventrodistally produced in strong triangular, slightly mesad process, distal margin very shallowly concave.
ANAL VALVES. With with moderate dorsal spine, a protruding ventral ‘corner’, margins raised, each with three setae on poorly developed ravelins.
LIMBUS (
Fig. 52D
). Striate, margin with very shallow lobes.
LEGS. With postfemoral and tibial pads, covering whole length of podomeres, from leg-pair ca 6, diminishing and eventually disappearing toward hind end.
FIRST PAIR OF LEGS (
Fig. 52E–G
). Prefemoral lobes with rounded-triangular in ventral view. Five to six coxosternal seta (
CXS
) close to lateral margin of coxosternum, well separated from prefemoral lobes. Prefemora with 2 of short mesapical setae (
APS
) and 5–12 peglike lateral setae (
LPS
).
STERNUM 9. Transversely rounded-triangular (not illustrated).
GONOPOD COXA (
Fig. 52A–C
). Slender, straight, almost parallel-sided, distolaterally with an almost equilateral triangular lateral process (
LCS
). Proplica (
PP
) simple, proplical lobe hibben behind fold of metaplica. Metaplica (
MP
) with a poorly delimited mesad flange (
MF
) basally, ca at mid-length with small, mesad triangular, process (
mtp
), distally with long, slender, strongly curved spinelike process (
msp
), process first directed basad then making a smooth 180° turn and projecting distad beyond gonopod tip.
GONOPOD TELOPODITE (
Fig. 53
). Arculus 80º. Torsotope (
TT
) extended, with angular lobe (
TL
) fitting into torsion. A long, stout post-torsal spine (
PTS
) making a full turn around post-torsal narrowing which is hence not evident. Solenomere and telomere originating near mesalmost part of telopodite, flexed back in front of and distal to torsotope. Solenomere (
SLM
) not very long, relatively stout, partially concealed within telomere, terminally flattened, pointed and transversely striate (
Fig. 53D
). Telomere (TM) shaped like an irregular bowl, smooth on the outside and along margins, with several contorted lamellae (
tml
) on the inside.
