Ruttellerona pulverulenta

Ruttellerona pulverulenta

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 (see below).

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.
