Type species: divergens Moore
Species in this genus are a medium reddish brown, the forewings having
two fine, straight fasciae darker red brown, a submarginal arising from the
tornus that converges with or meets an oblique postmedial at the costa. The
postmedial arises subbasally on the dorsum.
The fore tibia has an apical white patch, as does the coxa. The antennae
and palps are as in other members of the crescent-signum group.
In the male genitalia the uncus has the apex sclerotised and flexed
slightly ventrad. Arms arise from the base of the sacculus in a furca. These are
slender with a terminal cluster of long setae in one lineage and broad with a
terminal mass of shorter setae in a second lineage. P. irrorata West from
the Philippines and Sulawesi lacks a furca but has forewing facies similar to
that of the other species. P. kinabalua Holloway comb. n. and P.
divergens Moore belong to the first lineage, and P. albitermina Hering
stat. n. and a sister species or subspecies in the Himalaya belong to the
The female genitalia are of typical 'crescent signum' form.
The larva was compared by Piepers & Snellen (1900) to that of Cania
species, but they refer to complete rows of tubercles so the form may
approximate to that of Thosea.
