Type species. Leocrates diplognathus Monro, 1926.

Diagnosis. Hesioninae with two lateral antennae, and one median antenna on dorsal prostomial surface. Palps biarticulate, palpophores large, massive, palpostyles smaller, blunt. Eyes dark, black or brown, anterior ones larger than posterior ones, sometimes approaching each other in lateral view. Nuchal organs lobes L-shaped. Peristomial dorsolateral tubercles large, ventrolateral ones smaller; ventral ridge sometimes with marginal papillae. Pharynx with upper jaws double, lower one transverse plate. Parapodia sesquiramous along anterior 4 or 5 chaetigers, biramous thereafter. Notochaetae subdistally denticulate, delicate, sometimes abundant, size variable, never reaching neurochaetal tips. Neurochaetae compound falcigers, blades bidentate, guards approaching subdistal tooth.

Etymology. The genus-group name is derived from Lamprophaea Grube, 1867 reinstated (see above), with the Greek prefix Para - (= near) to emphasize their close resemblance.

Gender. Feminine, as the stem genus-group name.

Remarks. Paralamprophaea n. gen. resembles Lamprophaea Grube, 1867 because they have palps biarticulate, pharynx with jaws, nuchal organs lobes L-shaped, and parapodia sesquiramous anteriorly and biramous posteriorly. These two genera differ especially by the type of jaws. In Paralamprophaea the pharynx has upper jaw double, T-shaped, and lower one as a transverse plate, whereas in Lamprophaea the pharynx has upper and lower jaws single, fang-shaped.
