Catascia pulverulenta Warren,
1897, Novit. zool. 4: 250.
Diagnosis. Males in the pulverulenta group (see notes below) tend to be a
warmer, paler brown than those of pseudocessaria, but females are not
easily distinguishable. Both are most reliably diagnosed from their genitalia.
See R. pseudocessaria for male genitalia features. Females have the
ductus bursae surrounded by anterior and lateral sclerotisation as well as a
more extensive lamella postvaginalis similar to that of pseudocessaria, though
this has a central lobe or process that is bifurcate in a New Guinea specimen
(slide 16002) but entire in pulverulenta and R. scotozonea Hampson
Taxonomic notes. This taxon is based on a single female from an unusual locality. The
female genitalic features are held in common with, but are not identical to,
those of R.. scotozonea Hampson (Christmas I., Indian Ocean) and a
specimen from New Guinea (see above). An associated New Guinea male (slide
15973) had genitalia generally as in scotozonea but more close to those
of a male from Sulawesi (slide 15983, illustrated here). Clarification of the
identity of R. pulverulenta must await the acquisition of further
material. The genitalia are distinct from those of the only other Ruttellerona
in the Sundanian area, R. stigmaticosta Prout (Sumatra, Peninsular
Malaysia, Java, Bali): the manuscript name kalisi Prout, noted by
Holloway (1986), is synonymous with stigmaticosta.
Geographical range. Taganak I., 30km N.E. of Sandakan in Sabah,
politically part of the Philippines.
