In respect of size, relative proportions, colour, puncturation and male secondary sexual characters this new species is identical to
P. fissa
ASSING, 2013
, so these characters need not be described. The large aedeagus of
P. ceylonica
nov.sp.
is of the same
type
as that of
P. fissa
, with a pair of strongly sclerotised structures curved at their apex. In lateral view (
Fig. 10
al) these are abruptly bent at almost right angle, whereas they are gently curved in
P
.
fissa
; the shape of the large bifid ventral process is also different from that of
P. fissa
both in lateral and in ventral view. The pair of apical structures appears to be a partly internal structure, which is extruded in the specimen photographed in
Figs 10
al, 10av and retracted to lie under the dorsal plate in the specimen in
Figs 10
al2 and 10av2 (ventral process detached in 10al; dorsal plate detached in al2) The analogous structure in
P. fissa
illustrated by Assing appears to be in the same extruded position as the one in
Figs 10
al, 10av.
P. fissa
was described from two localities in neighbouring South
India
;
P. ceylonica
nov.sp.
is its vicariant sister species in
Sri Lanka
