In 1957, Dr. Olga Hartman published a most valuable account of the family Orbiniidae. She defined the subfamilies and genera, listed the known species with their synonyms and, inter alia
, described three new species and a new subspecies from Australia. In this volume it seems appropriate to carry on with this part of her work and give an account of all of the species now known from Australia and New Zealand.
Excluding records from Auckland and Campbell Islands, an examination showed that 11 valid species had been described under various names. Material in the Australian Museum and in other institutions and museums in Queensland, New South Wales, South Australia, Western Australia and New Zealand provided hundreds of specimens belonging to 20 species, of which six are new. Space does not permit me to deal fully with them all; this must await a separate paper. I have confined myself to the description of the new species and supplementary notes on the others. It is also necessary to erect a new, genus to replace Haploscoloplos
, whose definition does not accord with the character of its type species.
In 1973 I emended the definitions of the genera of the subfamily Orbiniinae and showed that the abruptly tapered "flail-setae" of the abdominal neuropodia that had been thought to characterize the genus Scolaricia
are not restricted to that genus, so that Scolaricia
became a synonym of Scoloplos
. The abundant Australian material showed that flail-setae are common in the genera Scoloplos
, but the abrupt tapering of the setal tip may be either well or poorly marked; it is a useful specific character. Another useful character which has seldom been used in descriptions is the shape of the abdominal neuropodia. They are usually bilobed on the first few feet, but thereafter the two lobes may remain subequal or the inner (preacicular) lobe may grow longer than the outer (postacicular) lobe or vice versa. In some cases one or other lobe is lost and the neuropodium becomes uniramous.
