Perixera
jocosa Warren
comb. n.
Platisodes jocosa Warren 1896, Novit. zool., 3: 114.
Diagnosis. This species shares with the next four a very short male hind-tibia with
a basal tuft of hair and three spurs close together, placed by Prout (1938, Gross
Schmett. Erde 12: 165-182) in his Brachycola section, but it differs
in facies markedly. The ground colour is pale yellow, speckled uniformly with
dull orange. The postmedials are blackish, dentate, and there is a distinctive
array of black spots submarginally: a central pair flanked widely by two single
dots, with an extra pair on the hindwing at the tornus. The forewing discal spot
is a black dot, that of the hindwing a larger black ring.
Taxonomic notes. P. glycydora Turner comb. n. & stat. rev. (= clara Prout
syn. n.; Seram, New Guinea, Queensland, Bismarcks) and P. thysanopoda Prout
comb. & stat. n. (=fimbripedata Warren, praeocc; Solomons)
have distinct male genitalia and represent good species. The group (referable to
Platisodes) has rather unusual naked coremata on the fourth sternite, and
a spine on the eighth sternite in the male abdomen but otherwise it lacks the
generic features. The hind-leg is normal, but the mid-tibia and tarsi have
scale tufts. The ornamentation of the valves is mainly saccular rather than
costal.
Geographical range. N.E. Himalaya to Sundaland.
Habitat preference. Only two specimens have been taken in recent surveys,
both from lowland dipterocarp forest (G. Mulu and Ulu Temburong).
