| Summary: | Genus Draconema Cobb, 1913 Synonymy: Decraemer et al. (1997): 187. Diagnosis (after Allen & Noffsinger 1978; Decraemer et al . 1997, Venekey et al. 2005, emended): Draconematinae. First anterior 7–14 annules of the cuticle enlarged. Twelve CATs on rostrum in two transverse rows. Amphids on rostrum, usually loop-shaped in males, open spiral or unispiral in females. No postanal PATs. Type species: Draconema cephalatum Cobb, 1913. The first extensive review of the genus Draconema was undertaken by Allen & Noffsinger (1978). They listed six valid species, two of them were described new for science ( D. chilense Allen & Noffsinger, 1978 from Chile and D. antarcticum Allen & Noffsinger, 1978 from Antarctica) and four known species were redescribed from type specimens ( D. cephalatum Cobb, 1913, Jamaica) or from specimens from the type or other localities ( D. haswelli (Irwin– Smith, 1918), from the type locality of New South Wales, Australia; D. claparedii (Metscnikoff 1867), from Naples, Italy close to the type locality; D. ophicephalum (Claparéde 1863), from Naples, Italy and Marseille, France while the type locality is Normandy, France). Redescriptions of the older species D. claparedii (Metscnikoff, 1867), D. haswelli (Irwin-Smith, 1918) and D. ophicephalum (Claparède, 1863) were supplied with long lists of junior synonyms. Decraemer et al . (1977) reviewed Draconematidae and largely accepted the synonymization of Allen & Noffsinger. They listed seven valid species of Draconema , with the addition of D. japonicum Kito, 1976 (Kito 1976, 1979). A few new Draconema species have been recorded since. Venekey et al . (2005) described two new species D. brasiliensis and D. fluminensis from Brazil and provided a useful table summarizing mensural and numerical characters of all valid species of the genus. Kito & Chatterjee (2012) added a further new species D. andamanense from the coast of Andaman Islands, Indian Ocean, and a dichotomous key for the identification all valid Draconema species known ... |
