with ‘L’ and ‘C’ code numbers for Lovedale and Coonoor handwritten under specimen cards.
Remarks
. Both this species and its synonym were described from an unknown number of specimens (
syntype
) with the following data: ‘Nilgiri Hills; Lovedale (T. V. Campbell)’. One specimen each of
P
.
montana
and
P
.
nilgiriensis
are considered
syntypes
as they have both BMNH registration labels dated before their publication date and original data labels. The remaining specimens listed under ‘Other material examined’ are topotypical but we cannot be sure of their status (see Material and Methods). This species and
P
.
quadrinotata
can be distinguished by their relatively pale dorsum (particularly females) but the former is larger and the genitalia is distinctly different. The aedeagal shaft of
P. montana
and
P. fraterna
is similar in having spicules and serrated lateral margins, however, they differ in the curvature of the shaft in lateral view and shape in caudal view (compare
Figs. 118, 119
with 137, 138). Although
P. nilgiriensis
was described first by
Distant (1918)
we prefer to use the name
P. montana
as its
type
