Remarks.
Another specimen from the
type
series that has not been examined is located in the collection at Cambridge. The original description does not mention the designation of a
holotype
, therefore these specimens are regarded as
syntypes
. The specimen from
Mahé
labelled
Type
, H. T., is hereby designated as
lectotype
to provide a diagnostic reference for the species.

Remarks.

Pandanus sechellarum
Balf.

Pandanus multispicatus
Balf.
f.
Colour.
Body including lateral carinae of vertex and frons yellow. Apex of rostrum blackish. Forewing yellow with some whitish areas and with one black spot at the apex of clavus, sometimes with a longitudinal brown streak along entire wing, veins concolorous with cells.
Morphology.
Body length: male
6.8–7.2 mm
, female
7.8–7.9 mm
.
Head: Vertex 0.7–0.8 times as long as wide. Frons 3.3 times longer than wide.
Thorax: Forewing 4.8–4.9 times longer than wide (at level of apex of clavus).
Hind
leg: 1st tarsomere with 6–7 apical teeth.
Male genitalia: Anal tube very long, apex bilobate (
Figs 14
A–B); pygofer laterally with a pointed process, ventromedian process of pygofer long, bifurcate, with a long, straight process on the left and a strongly curved, partially serrate process on the right side (
Fig. 14
C). Aedeagus with five apical spines, very similar to the aedeagus of
P. b i m a c u l a t a
(see below).
Diagnosis.
This species can be differentiated from
P. b i m a c u l a t a
by the colouration of the lateral carinae of the vertex (yellowish in
P. aurea
, blackish in
P. bimaculata
), by the absence of a black spot near the apex of the forewing, by the different shape of the ventromedian process of the male pygofer and the apical lobes of the male anal tube.
