Description.
Adult (
Fig. 42
). Wingspan. Female
23 mm
. Ground colour leaf green, without pale irroration. Forewing with very small white spot at 1/2 of the inner margin. Black discal dots conspicuous on all wings. White, triangular terminal dots at vein endings of all wings. Fringe darker, slightly chequered. Hindwing termen slightly angled at M3. Length of female palpi 2.1 times diameter of eye, length of last segment
0.7 mm
, tip and upperside palpi pale brown, underside white. Frons pale brown. Antennae filiform in female. Female hindtibia with four spurs.
Female genitalia (
Fig. 109
). Sterigma (lamella ante- and postvaginalis) fused to a round sclerite. Ductus bursae very narrow. Corpus bursae large, oval, membranous. Signa developed as conspicuous, paired, large, spinose crests.
Differential diagnosis.
Smaller than
P. gemmifera
sp. n.
From both
P. gemmifera
sp. n.
and
P. albisticta
differing in the more conspicuous discal dots, moreover in
P. discipuncta
sp. n.
the triangular terminal dots are not separated from the green ground colour by a dark line. In female genitalia
P. gemmifera
sp. n.
differs from
P. discipuncta
sp. n.
in the different shape of the sterigma and in the much stronger spinose corpus bursae. In habitus somewhat reminiscent of the examined
type
specimen of
P. salutaria
(Swinhoe, 1904)
(described as
Thalassodes
from
Uganda
), but the latter with triangular terminal dots less conspicuous and in female genitalia without signa.
Genetic data.
BIN: BOLD:ABA3724, one further specimen with identic sequence from
Sierra Leone
. Nearest neighbour in
Ethiopia
:
P. gemmifera
(4.4%). Genetically not far from
P. salutaria
(6.5%), distance from
P. albisticta
7.8%, from
P. niveisticta
8.5%.
