Neolebouria khalili ( Ramadan, 1983) n. comb.

Synonyms: Hamacreadium khalili Ramadan, 1983 .

Records. From Lethrinus mahsena and L. nebulosus in the Red Sea by Ramadan (1983) as H. khalili . From L. mahsena , L. nebulosus and the snubnose emperor, Lethrinus borbonicus Valenciennes , in the Red Sea by El-Labadi et al. (2005) as H. khalili . From the lavender jobfish, Pristipomoides sieboldii (Bleeker) (Lutjanidae) , and the yellow-edged lyretail, Variola louti (Forsskål) (Serranidae) , by El-Labadi et al. (2006) as H. khalili .

Remarks. This species broadly agrees with the concept of Hamacreadium , except that the body is smaller than is typical for Hamacreadium species (1,700–3,100 µm long), the oesophagus is short and the genital pore is prebifurcal. The anterior extent of the excretory vesicle was not determined. Overall, these characters make it most consistent with Neolebouria , to which it is transferred here. It is most similar to Neolebouria krusadaiensis (Gupta, 1956) Gibson, 1976 but the ovary is described with six to nine lobes instead of three, the post-testicular length is longer and the vitelline follicles are interrupted at the level of the ventral sucker. The description provided by El- Labadi et al. (2005) is inconsistent with that of Ramadan (1983) and more likely represents H. morgani , because the body is large (4,224 µm long), the oesophagus is comparatively long and the genital pore is post-bifurcal. The identity of the records of El-Labadi et al. (2006) are difficult to determine because no description was provided and they also reported a species of Cainocreadium from the same hosts.
