Diagnosis "As Scoloplos, but with crenate capillary bristles only" (Monro, 1933: 261). [details]
Diagnosis Pre later synonymy, the diagnosis in Fauchald (1977:16) was: ORBINIINAE with pointed prostomium, branchiae not present before setiger 9; posterior thoracic neuropodia with two papillae and maximally two ventral papillae present; never more than four papillae combined. All neurosetae crenulated capillaries; notosetae crenulated capillaries and in some cases furcate setae. [details]
Etymology The name of the genus is formed by the prefix of Greek origin haplo-, meaning 'simple' or 'single', and the name of the stem genus Scoloplos, meaning a thorn or pointed bristle, and refers probably to the presence of one single type of chaetae, which are crenate capillary bristles. [details]
Synonymy Day (1977: 218) placed Haploscoloplos Monro, 1933 as a synonym of Scoloplos because specimens of the type species, Haploscoloplos cylindrifer (was Scoloplos cylindrifer), had some "easily overlooked" 'hooks' (also termed 'uncini', or even 'spines', all somewhat misleading terms as the chaetae are 'blunt' and may simply lack the tapering end of the so-called 'capillaries') in thoracic neurochaetae, whereas the genus definition of Monro stated only neurochaetal capillaries were present. According to Blake (2017) species with prominent 'spines' belong in Leodamas, leaving those with a few inconspicuous 'uncini' belonging in Scoloplos sensu stricto, and those without 'uncini' in Leitoscoloplos, Day's (1977) new genus. However, while there could be said to be imprecise separation solely on this basis, these are not quite the only characters separating the three genera. Blake (2017: 50) has a long comment summarizing the treatments of S. cylindrifer. He places Scoloplos cylindrifer, type of Haploscoloplos, as a Leodamas. Although not noted by Blake (he does not assign Haploscoplos to any genus synonymy), this also logically makes Haploscoloplos a synonym of Leodamas, not of Scoloplos. [details]
