 , 15-19mm. Externally, this species is indistinguishable from P.
pannosa (Himalaya,
Taiwan), the facies being distinguished under P. metagona above.
However, the male and female genitalia are significantly different. The male
(see note below) has the uncus more elongate, slender and apically spatulate.
The valves have a straight, tapered distal process with a lateral spur, rather
than a markedly coiled one, and a triangular process from the sacculus, rather
than a slender, parallel-sited one. In both species the saccus is acute and the
vesica has a cornutus basally, an asymmetric one on one long diverticulum and a
group of short, robust spines on the other. In the female (compared with the
holotype of duplicilinea
Hampson),
there are larger lateral lobes to the reduced seventh sternite, the posterior
margin of which is much shorter, straight rather than concave. The lateral
sclerotisation of the ductus is narrower but extends significantly into the
corpus bursae.

Taxonomic
note. The BMNH syntype of pannosa from
Darjeeling is a female that has lost its abdomen. A male from Sikkim (slide
15968) is taken here to represent pannosa,
as syntypic material in MNHU, Berlin, has not been located. A male from Taiwan
(slide 15962) has similar genitalia. The taxon griseistriga Bethune-Baker is a good species as
discussed above under paragona. Hampson, in his original description of duplicilinea
(currently
a synonym of pannosa), referred to ‘Type’ in the singular and
annotated as such the Sikkim specimen he referred to as female. His material
from Borneo and Java, that Poole (1989) referred to erroneously as syntypic, is
probably that treated under paragona above. A male from the Naga area,
mistakenly labelled as the type of duplicilinea,
is in fact metagona.
A specimen from N. Thailand (slide 15969) may represent a third species in the pannosa complex, having a longer but only slightly sinuous
distal process to the valve and a smaller, digitate one on the sacculus. A
female from Peninsular Malaysia has genitalia (slide 19266) as in the holotype
of duplicilinea.
Geographical
range. Borneo, Java (slide 19268).
Habitat
preference. The species is frequent from 1000m to 1930m.
