Diagnosis According to Blake (2017) Leodamas of Blake Group A (including type species L. verax) have large, conspicuous spines in thoracic neuropodia, in several (3 or more) rows, with few or no accompanying capillaries, and branchiae usually from setigers 4–6. Leodamas of Blake Group B have (less conspicuous) thoracic neuropodial uncini in only 1–2 rows, with similar number of capillaries as there are uncini, and branchiae from posterior thoracic or anterior abdominal setigers. Abdominal neuropodial aciculae tend to be projecting in Leodamas species. Whereas Scoloplos species have few uncini, not conspicuous, not in rows, and abdominal neuropodial aciculae tend to be small and imbedded. [details]
Etymology Kinberg can safely be assumed to have chosen Leodamas as another historic Greek personal name, as was his practice, although Blake (2017) has suggested a different imaginative etymology (see below), Kinberg may have been working alphabetically through a Greek dictionary as he also uses Leonnatus and Leocrates in the same work, and many other such names. In Greek history there is Leodamas of Thasos (c. 380 BC), Leocrates was a leading Athenian general of the First Peloponnesian War, and Leonnatus was a Macedonian officer of Alexander the Great. However, Blake (2017: 49) suggested the name could be "formed from Leo, Greek for lion, and dama, Latin for deer [as it] seems likely that Kinberg noticed the branches of the thoracic notopodial lamellae and compared them with antlers of a deer, hence the name." This suggestion is (put politely) not credible (where does the lion fit in?) and should be disregarded. [details]
Grammatical gender Not stated but assumed masculine as Leodamas is a male personal name. Past authors have treated Leodamas as masculine. The type species-group name is not helpful as it is assumed to be from the Latin adjective 'verax' (truthful or speaking truly), which has unchanged ending whether masculine, feminine, or neuter, although Blake (2017: 49) assumes it could only be masculine. [details]
Taxonomy Blake (2000) treated Leodamas as a full genus because of its heavy thoracic neuropodial spines, which differ from the narrow spines of Scoloplos. A morphology-based cladistic analysis indicated this was justified, however molecular support is not yet tested. Blake (2017) extended the number of species in Leodamas with several new combinations and three new species. His diagnosis of Scoloplos versus Leodamas hinges on relatively minor differences. These are that in Scoloplos thoracic neurochaetae include blunt, inconspicuous uncini, few in number, not in distinct rows; abdominal neuropodia with embedded, non-projecting acicula, and in Leodamas the thoracic neuropodial uncini are large, conspicuous, arranged in one to many distinct vertical rows, with accompanying capillaries few; abdominal neuropodia with projecting aciculae, either thin and inconspicuous or large. The problem is these are somewhat subjective gradational differences with some species (eg Scoloplos cylindrifer) not clearly belonging to either genus. Subsequently Zhadan (2020: 454) did not accept Blake's transfer of several Scoloplos (Blake's group B) to Leodamas in part because Scoloplos remained heterogeneous, and molecular support was lacking for the morphological differences noted by Blake. See Scoloplos (Leodamas) for a number of species not yet assigned to either genus. [details]
