Remarks.
Specimens studied here fit fully within the variation encompassed by previous descriptions (following the synonymy by
Lewis and Gallagher 1993
). The Ethiopian specimens have 19 antennal articles, three of which are glabrous (
Fig. 23
), 5+5 forcipular teeth (
Fig. 24
), continuous paramedian sutures from
TT
5–20, paramedian sutures confined to a short anterior extent on the sternites, the diagnostic three prefemoral spines (1VL, 1VM, 1 DM) confined to the proximal half of the prefemur (
Fig. 25
), the coxopleural process with two apical spines but no dorsal or lateral spines (
Fig. 26
), two tarsal spurs on legs 1–18, and one tibial spur on legs 1–4.
Lewis and Gallagher (1993)
followed
Attems (1930)
in treating
R. paucidens
as a subspecies of
R. lithobioides
(
Newport, 1845
)
, resulting in a geographically widespread species distributed from
China
through
India
and East Africa to the Arabian Peninsula. They noted, however, that the nominate subspecies (from
East Asia
) was “quite distinct from the others” (1993: 59), and we regard the cited differences in the number of legs bearing two tarsal spurs and prefemoral spine numbers and distributions, as sufficient to defend separate species status. Accordingly we returned
R. lithobioides paucidens
to the species level (as in
Kraepelin 1903
).
