Description.
Adult (
Fig. 27
). Wingspan. Female
32 mm
. Ground colour pale bluish green, irrorated with white strigulae. Forewing without spot at the inner termen. Fore- and hindwings with an inconspicuous black discal dot, terminal dots absent. Hindwing termen slightly angled at M3. Length of female palpi 2.0 times diameter of eye, tip and upperside reddish, underside white. Frons green, reddish towards vertex. Antennae filiform in female.
Female genitalia (
Fig. 95
). Apophyses comparatively long. Sterigma semi-membranous with granulose surface, posteriorly with alate projections, anteriorly shallowly bilobous, bent upwards (ventrad). Ductus bursae long. Corpus bursae oval. Signum developed as a transverse sclerite, anteriorly with two spinules.
Differential diagnosis.
Several species are similar in habitus, e.g.
P. aquamarina
sp. n.
,
P. monikae
sp. n.
and
P. beryllaria
sp. n.
, the last two being available only in the opposite sex but clearly distinct in their COI barcode.
P. aquamarina
sp. n.
differs also in female genitalia in its shorter ductus bursae and the stronger slerotization of the furrowed sterigma. The 'closest' genetic ally
P. amharensis
differs from
P. lutulenta
sp.n.
in the completely lacking discal dots, in female genitalia in the strikingly different shape of the sterigma.
Genetic data.
BIN: BOLD:ACL9893. Nearest neighbour in
Ethiopia
:
P. amharensis
sp. n.
(9.4%), distance from an undescribed
Prasinocyma
species (
Tanzania
, province Iringa) 6.8%. Genetically strongly diverging from all other species (>150 species) so far barcoded from the African continent, thus a description based on a single female seems justified.
Etymology.
The name refers to the red and green frons and palpi, lat. lutulentus = multicolorous.
