[None. Work starts as follows:]
Loandalia Monro and Parandalia Emerson & Fauchald are two closely allied pilargid genera. Both have a rather cylindrical body with reduced parapodia anteriorly and enlarged parapodia posteriorly. The prostomial appendages are also similar since they both lack antennae and have bifid, often biarticulated palps. Setae are also similar; notosetae are simple spines sometimes with one or two smaller companion setae dorsally and neurosetae are spinulous capillaries.
When establishing Parandalia, Emerson and Fauchald (1971) set the differences between both genera. Loandalia was restricted to the type-species (L. aberrans Monro), described from one specimen collected off Angola which lacks notopodial spines and has unusually well-developed branchiae in posterior setigers. Parandalia was separated from Loandalia by possessing notospines and lacking branchiae in posterior setigers. These authors noted, however, that Monro (1936) had described notospines though they did not find any when the type specimen was examined. The branchiae on Monro's specimen are unusual since they are directed ventrolaterally and free from neuropodial lobes. The original designation of these structures as branchiae has been retained by other authors.
