Taxonomic position of
Pandipalpus lowei
(Kovařík
,
2012)
Prendini & Loria (2020: 442) formally synonymized
Pandinus lowei
KovařÍk, 2012
under
Pandinus viatoris
Pocock, 1890
(both now in the genus
Pandipalpus
), citing only “
unpublished data
” and not providing specific details or analyses to support their taxonomic act. They wrote: “
It is also evident, based firstly on the absence of consistent morphological differences, and secondly on low genetic divergence between samples collected at the
type
locality of
Pandinus lowei
Kovařík, 2012
, and across the distribution of
P. viatoris
(unpublished data), that these taxa are conspecific, justifying the following synonymy
”. However, the claim of “
the absence of consistent morphological differences
” is inconsistent with our data. For example, as illustrated in
Figs. 77–81
, there are pronounced differences in the morphometrics and granulation of the pedipalp chelae of these two species. The
P
.
viatorus
male from Kamonga,
Democratic Republic of Congo
(
Fig. 79
), a locality relatively close (
250 km
) to the
type
locality of
P
.
lowei
(Lusinga, Parc National de Upemba,
Democratic Republic of Congo
) has distinctly more elongate pedipalp fingers and weaker manus granulation vs. the
P
.
lowei
male (
Fig. 77
). The chela of another
P
.
viatorus
male (
Fig. 81
) is very similar, although it originates from
Iringa
,
Tanzania
, a locality separated from Kamonga by
1,100 km
. Also very similar is the chela of another male from
92 km
NW of Mpika,
Zambia
(
460 km
from Kamonga) (see fig.
38 in
KovařÍk, 2012: 12). This indicates that the morphology is stable over the wide geographic range of
P
.
viatoris
(KovařÍk, 2012: 19, fig. 64), and there is no obvious character gradient that links or overlaps with
P
.
lowei
. Other diagnostic characters separating the two species were cited in KovařÍk (2012). The second justification of synonymy by “
low genetic divergence
“ was not demonstrated in Prendini & Loria (2020), and there was no indication that the authors analyzed the
types
of these species. Considering the absence of convincing evidence for synonymy, and the documented morphological differences, we reinstate
Pandipalpus lowei
(KovařÍk, 2012)
as a valid species distinct from
P. viatoris
(Pocock, 1890)
.
